This paper shows a chatbot solution for eGLU-box Pro, a usability testing platform for Italian Public Administration (PA). eGLU-box Pro is a web-based tool designed to help PA practitioners in creating remote usability tests and analyzing participants’ answers and interaction data after they complete the usability tasks. The impact of the chatbot solution on users’ experience was assessed by bio-behavioral evaluation methods such as eye tracking, electroencephalography, and facial expression recognition. This work describes the platform and its integrated chatbot solution and shows the results of a preliminary laboratory study involving 20 end-users. The study is part of an ongoing design and development project based on a user-centered approach.

ObjectiveTo ascertain the reliability of a standardised, short-scale measure of satisfaction in the use of new healthcare technology i.e., the LITE version of the usability metric for user experience (UMUX-LITE). Whilst previous studies have demonstrated the reliability of UMUX-LITE, and its relationship with measures of likelihood to recommend a product, such as the Net Promoter Score (NPS) in other sectors no such testing has been undertaken with healthcare technology.Materials and methodsSix point-of-care products at different stages of development were assessed by 120 healthcare professionals. UMUX-LITE was used to gather their satisfaction in use, and NPS to declare their intention to promote the product. Inferential statistics were used to: i) ascertain the reliability of UMUX-LITE, and ii) assess the relationship between UMUX-LITE and NPS at different stages of products development.ResultsUMUX-LITE showed an acceptable reliability (α = 0.7) and a strong positive correlation with NPS (r = 0.455, p < .001). This is similar to findings in other fields of application. The level of product development did not affect the UMUX-LITE scores, while the stage of development was a significant predictor (R2 = 0.49) of the intention to promote.Discussion and conclusionPractitioners may apply UMUX-LITE alone, or in combination with the NPS, to complement interview and ‘homemade’ scales to investigate the quality of new products at different stages of development. This shortened scale is appropriate for use in the context of healthcare in which busy professionals have a minimal amount of time to support innovation.

People with disabilities or special needs can benefit from AI-based conversational agents, which are used in competence training and well-being management. Assessment of the quality of interactions with these chatbots is key to being able to reduce dissatisfaction with them and to understand their potential long-term benefits. This will in turn help to increase adherence to their use, thereby improving the quality of life of the large population of end-users that they are able to serve. We systematically reviewed the literature on methods of assessing the perceived quality of interactions with chatbots, and identified only 15 of 192 papers on this topic that included people with disabilities or special needs in their assessments. The results also highlighted the lack of a shared theoretical framework for assessing the perceived quality of interactions with chatbots. Systematic procedures based on reliable and valid methodologies continue to be needed in this field. The current lack of reliable tools and systematic methods for assessing chatbots for people with disabilities and special needs is concerning, and may lead to unreliable systems entering the market with disruptive consequences for users. Three major conclusions can be drawn from this systematic analysis: (i) researchers should adopt consolidated and comparable methodologies to rule out risks in use; (ii) the constructs of satisfaction and acceptability are different, and should be measured separately; (iii) dedicated tools and methods for assessing the quality of interaction with chatbots should be developed and used to enable the generation of comparable evidence.

AIMS: To test a hypothesis that cataract operating room (OR) productivity can be improved with a femtosecond laser (FL) using a hub-and-spoke model and whether any increase in productivity can offset additional costs relating to the FL. METHODS: 400 eyes of 400 patients were enrolled in a randomised-controlled trial comparing FL-assisted cataract surgery (FLACS) with conventional phacoemulsification surgery (CPS). 299 of 400 operations were performed on designated high-volume theatre lists (FLACS=134, CPS=165), where a hub-and-spoke FLACS model (1×FL, 2×ORs=2:1) was compared with independent CPS theatre lists. Details of operative timings and OR utilisation were recorded. Differences in productivity between hub-and-spoke FLACS and CPS sessions were compared using an economic model including testing hypothetical 3:1 and 4:1 models. RESULTS: The duration of the operation itself was 12.04±4.89 min for FLACS compared with CPS of 14.54±6.1 min (P<0.001). Total patient time in the OR was reduced from 23.39±6.89 min with CPS to 20.34±5.82 min with FLACS (P<0.001)(reduction of 3.05 min per case). There was no difference in OR turnaround time between the models. Average number of patients treated per theatre list was 9 for FLACS and 8 for CPS. OR utilisation was 92.08% for FLACS and 95.83% for CPS (P<0.001). Using a previously established economic model, the FLACS service cost £144.60 more than CPS per case. This difference would be £131 and £125 for 3:1 and 4:1 models, respectively. CONCLUSION: The FLACS hub-and-spoke model was significantly faster than CPS, with patients spending less time in the OR. This enabled an improvement in productivity, but insufficient to meaningfully offset the additional costs relating to FLACS.

Aim To provide a quantitative assessment of cataract theatre lists focusing on productivity and staffing levels/tasks using time and motion studies.Methods National Health Service (NHS) cataract theatre lists were prospectively observed in five different institutions (four NHS hospitals and one private hospital). Individual tasks and their timings of every member of staff were recorded. Multiple linear regression analyses were performed to investigate possible associations between individual timings and tasks.Results 140 operations were studied over 18 theatre sessions. The median number of scheduled cataract operations was 7 (range: 5–14). The average duration of an operation was 10.3 min±(SD 4.11 min). The average time to complete one case including patient turnaround was 19.97 min (SD 8.77 min). The proportion of the surgeons’ time occupied on total duties or operating ranged from 65.2% to 76.1% and from 42.4% to 56.7%, respectively. The correlations of the surgical time to patient time in theatre was R2=0.95. A multiple linear regression model found a significant association (F(3,111)=32.86, P<0.001) with R2=0.47 between the duration of one operation and the number of allied healthcare professionals (AHPs), the number of AHP key tasks and the time taken to perform these key tasks by the AHPs.Conclusions Significant variability in the number of cases performed and the efficiency of patient flow were found between different institutions. Time and motion studies identified requirements for high-volume models and factors relating to performance. Supporting the surgeon with sufficient AHPs and tasks performed by AHPs could improve surgical efficiency up to approximately double productivity over conventional theatre models.

INTRODUCTION: The slow adoption of innovation into healthcare calls into question the manner of evidence generation for medical technology. This paper identifies potential reasons for this including a lack of attention to human factors, poor evaluation of economic benefits, lack of understanding of the existing healthcare system and a failure to recognise the need to generate resilient products. Areas covered. Recognising a cross-disciplinary need to enhance evidence generation early in a technology's life cycle, the present paper proposes a new approach that integrates human factors and health economic evaluation as part of a wider systems approach to the design of technology. This approach (Human and Economic Resilience Design for Medical Technology or HERD MedTech) supports early stages of product development and is based on the recent experiences of the National Institute for Health Research London Diagnostic Evidence Co-operative in the UK. Expert commentary. HERD MedTech i) proposes a shift from design for usability to design for resilience, ii) aspires to reduce the need for service adaptation to technological constraints iii) ensures value of innovation at the time of product development, and iv) aims to stimulate discussion around the integration of pre- and post-market methods of assessment of medical technology.

Aims(1) To model the process of use and usability of pH strips (2) to identify, through simulation studies, the likelihood of misreading pH strips, and to assess professional’s acceptance, trust and perceived usability of pH strips.MethodsThis study was undertaken in four phases and used a mixed method approach (an audit, a semi-structured interview, a survey and simulation study). The three months audit was of 24 patients, the semi-structured interview was performed with 19 health professionals and informed the process of use of pH strips. A survey of 134 professionals and novices explored the likelihood of misinterpreting pH strips. Standardised questionnaires were used to assess professionals perceived usability, trust and acceptance of pH strip use in a simulated study.ResultsThe audit found that in 45.7% of the cases aspiration could not be achieved, and that 54% of the NG-tube insertions required x-ray confirmation. None of those interviewed had received formal training on pH strips use. In the simulated study, participants made up to 11.15% errors in reading the strips with important implications for decision making regarding NG tube placement. No difference was identified between professionals and novices in their likelihood of misinterpreting the pH value of the strips. Whilst the overall experience of usage is poor (47.3%), health professionals gave a positive level of trust in both the interview (62.6%) and the survey (68.7%) and acceptance (interview group 65.1%, survey group 74.7%). They also reported anxiety in the use of strips (interview group 29.7%, survey group 49.7%).ConclusionsSignificant errors occur when using pH strips in a simulated study. Manufacturers should consider developing new pH strips, specifically designed for bedside use, that are more usable and less likely to be misread.

BACKGROUND: This study was an extension of research which began in the Umbria region in 2009. AIM: To investigate the extent to which assistive technology (AT) has been abandoned by users of the Italian National Health Service (ULHS) and the reasons for this. DESIGN: Observational study. SETTING: Users who received a hearing device (HD) or mobility device (MD) by ULHS between 2010 and 2013. POPULATION: 749 out of 3,791 ULHS users contacted via telephone completed the interview: 330 (44.06%) had a HD and 419 (55.94%) a MD. METHODS: Data were collected using a specially developed telephone interview questionnaire including the Italian version of the Quebec User Evaluation of Satisfaction with AT (QUEST 2.0) and Assistive Technology Use Follow-up Survey (ATUFS). RESULTS: 134 users (17.9%) were no longer using their assigned AT device within seven months of issue and 40% of this group reported that they had never used the device. Duration of use (for how long the AT device was used before abandonment) and satisfaction with service delivery did not predict AT abandonment. People who received a HD where more likely to abandon their device (22.4%) than those who received a MD (14.4%). CONCLUSIONS: Abandonment may be due to assignment of inappropriate devices or failure to meet user needs and expectations. These findings are consistent with previous data collected by Federici and Borsci in 2009. Utility of AT in use, reasons of abandonment, and importance of device and service satisfaction for the use or non-use of an AT are presented and discussed. CLINICAL REHABILITATION IMPACT: AT abandonment surveys provide useful information for modelling AT assessment and delivery process. The study confirms the relevance of person centredness approach for a successful AT assessment and delivery process.

An empirical analysis was performed to compare the effectiveness of different approaches to traininga set of procedural skills to a sample of novice trainees. Sixty-five participants were randomlyassigned to one of the following three training groups: i) learning-by-doing in a 3D desktop virtualenvironment, ii) learning-by-observing a video (show-and-tell) explanation of the procedures, and iii)trial-and-error. In each group participants were trained on two car service procedures. Participantswere recalled to perform a procedure either two or four weeks after the training. The results showedthat: i) participants trained through the virtual approach of learning-by-doing performed bothprocedures significantly better (i.e., p <.05 in terms of errors and time) than people of non-virtualgroups. ii) The virtual training group, after a period of non-use, were more effective than non-virtualtraining (i.e., p <.05) in their ability to recover their skills. iii) After a (simulated) long period from thetraining – i.e., up to 12 weeks – people who experienced 3D environments consistently performedbetter than people who received other kinds of training. The results also suggested that independentlyfrom the training group, trainees’ visuospatial abilities were a predictor of performance, at least forthe complex service procedure, Adj R2= .460, and that post-training performances of people trainedthrough virtual learning-by-doing are not affected by learning styles. Finally, a strong relationship(p<..001 R2 =.441) was identified between usability and trust in the use of the virtual training tool –i.e., the more the system was perceived as usable, the more it was perceived as trustable to acquire thecompetences

Use of in-vitro point of care devices - intended as tests performed out of laboratories and near patient - is increasing in clinical environments. International standards indicate that interaction assessment should not end after the product release, yet human factors methods are frequently not included in clinical and empirical studies of these devices. Whilst the literature confirms some advantages of bed-side tests compared to those in laboratories there is a lack of knowledge of the risks associated with their use. This article provides a review of approaches applied by clinical researchers to model the use of in-vitro testing. Results suggest that only a few studies have explored human factor approaches. Furthermore, when researchers investigated people-device interaction these were predominantly limited to qualitative and not standardised approaches. The methodological failings and limitations of these studies, identified by us, demonstrate the growing need to integrate human factors methods in the medical field.

This paper reports a study which demonstrates the advantages of using virtual-reality-based systems for training automotive assembly tasks. Sixty participants were randomly assigned to one of the following three training experiences to learn a car service procedure: (1) observational training through video instruction; (2) an experiential virtual training and trial in a CAVE; and (3) an experiential virtual training and trial through a portable 3D interactive table. Results show that virtual trained participants, after the training, can remember significantly better (p < .05) the correct execution of the steps compared to video-trained trainees. No significant differences were identified between the experiential groups neither in terms of post-training performances nor in terms of proficiency, despite differences in the interaction devices. The relevance of the outcomes for the automotive fields and for the designers of virtual training applications are discussed in light of the outcomes, particularly that virtual training experienced through a portable device such as the interactive table can be effective, as can training performed in a CAVE. This suggests the possibility for automotive industries to invest in advanced portable hardware to deliver effectively long-distance programs of training for car service operators placed all over the world.

Borsci S, Federici S, Bacci S, Gnaldi M, Bartolucci Fet al., 2015, Assessing user satisfaction in the era of user experience: comparison of the SUS, UMUX and UMUX-LITE as a function of product experience, International Journal of Human-Computer Interaction, Vol: 31, Pages: 484-495, ISSN: 1532-7590

Nowadays, practitioners extensively apply quick and reliable scales of user satisfaction as part of their user experience (UX) analyses to obtain well-founded measures of user satisfaction within time and budget constraints. However, in the human-computer interaction (HCI) literature the relationship between the outcomes of standardized satisfaction scales and the amount of product usage has been only marginally explored. The few studies that have investigated this relationship have typically shown that users who have interacted more with a product have higher satisfaction. The purpose of this paper was to systematically analyze the variation in outcomes of three standardized user satisfaction scales (SUS, UMUX and UMUX-LITE) when completed by users who had spent different amounts of time with a website. In two studies, the amount of interaction was manipulated to assess its effect on user satisfaction. Measurements of the three scales were strongly correlated and their outcomes were significantly affected by the amount of interaction time. Notably, the SUS acted as a unidimensional scale when administered to people who had less product experience, but was bidimensional when administered to users with more experience. We replicated previous findings of similar magnitudes for the SUS and UMUX-LITE (after adjustment), but did not observe the previously reported similarities of magnitude for the SUS and the UMUX. Our results strongly encourage further research to analyze the relationships of the three scales with levels of product exposure. We also provide recommendations for practitioners and researchers in the use of the questionnaires.

Borsci S, Federici S, Mele ML, Conti Met al., 2015, Short scales of satisfaction assessment: A proxy to involve disabled users in the usability testing of websites, Pages: 35-42, ISSN: 0302-9743

Short scales of user satisfaction analysis are largely applied in usability studies as part of the measures to assess the interaction experience of users. Among the traditional tools, System Usability Scale (SUS), composed of 10 items, is the most applied quick evaluation scale. Recently, researchers have proposed two new and shorter scales: the Usability Metric for User Experience (UMUX), composed of four items, and the UMUX-LITE, which consists of only the two positive items of UMUX. Despite their recent creation, researchers in human-computer interaction (HCI) have already showed that these two tools are reliable and strongly correlated to each other [1–3]. Nevertheless, there are still no studies about the use of these questionnaires with disabled users. As HCI experts claim [4–7], when disabled and elderly users are included in the assessment cohorts, they add to the overall analysis alternative and extended perspectives about the usability of a system. This is particularly relevant to those interfaces that are designed to serve a large population of end-users, such as websites of public administration or public services. Hence, for a practitioner adding to the evaluation cohorts a group of disabled people may sensibly extend number and types of errors identified during the assessment. One of the major obstacles in creating mixed cohorts is due to the increase in time and costs of the evaluation. Often, the budget does not support the inclusion of disabled users in the test. In order to overcome these hindrances, the administering to disabled users of a short questionnaire—after a period of use (expert disabled costumers) or after an interaction test performed through a set of scenario-driven tasks (novice disabled users)—permits to achieve a good trade-off between a limited effort in terms of time and costs and the advantage of evaluating the user satisfaction of disabled people in the use of websites. To date, researchers have neither

It is important for practitioners to conceptualize and tailor a prototype in tune with the users’ expectations in the early stages of the design life cycle so the modifications of the product design in advanced phases are kept to a minimum. According to user preference studies, the aesthetic and the usability of a system play an important role in the user appraisal and selection of a product. However, user preferences are just a part of the equation. The fact that a user prefers one product over the other does not mean that he or she would necessarily buy it. To understand the factors affecting the user's assessment of a product before the actual use of the product and the user's intention to purchase the product we conducted a study, reported in this article. Our study, a modification of a well-known protocol, considers the users’ preferences of six simulated smartphones each with different combination of attributes. A sample consisting of 365 participants was involved in our analysis. Our results confirm that the main basis for the users’ pre-use preferences is the aesthetics of the product, whereas our results suggest that the main basis for the user's intention to purchase are the expected usability of the product. Moreover, our analysis reveals that the personal characteristics of the users have different effects on both the users’ preferences and their intention to purchase a product. These results suggest that the designers should carefully balance the aesthetics and usability features of a prototype in tune with the users expectations. If the conceptualization of a product is done properly the redesign cycles after the usability testing can be reduced and speed up the process for releasing the product on the market.

Federici S, Scherer MJ, Borsci S, 2014, An ideal model of an assistive technology assessment and delivery process, Technology and disability, Vol: 26, Pages: 27-38, ISSN: 1878-643X

The purpose of the present work is to present some aspects of the Assistive Technology Assessment (ATA) process model compatible with the Position Paper 2012 by AAATE/EASTIN. Three aspects of the ATA process will be discussed in light of three topics of the Position Paper 2012: (i) The dimensions and the measures of the User eXperience (UX) evaluation modelled in the ATA process as a way to verify the efficient and the evidence-based practices of an AT service delivery centre; (ii) The relevance of the presence of the psychologist in the multidisciplinary team of an AT service delivery centre as necessary for a complete person-centred assistive solution empowering users to make their own choices; (iii) The new profession of the psychotechnologist, who explores user's needs by seeking a proper assistive solution, leading the multidisciplinary team to observe critical issues and problems. Through the foundation of the Position Paper 2012, the 1995 HEART study, the Matching Person and Technology model, the ICF framework, and the pillars of the ATA process, this paper sets forth a concept and approach that emphasise the personal factors of the individual consumer and UX as key to positively impacting a successful outcome and AT solution.
