Aurisicchio M, Langdon PM, Ahmed S, et al., 2003, Investigating knowledge searches in aerospace design, ISSN: 2220-4334
This research was undertaken to develop empirical understanding on how information searches are carried out in the aerospace industry. Ethnographical participation was used in conjunction with observations involving shadowing and diary-study methods. Ethnographical methods were adopted to characterise aspects of the social and organisational behaviour of engineers in an aerospace company and to generate insights into information searches undertaken in a real working environment. A group of fourteen engineers was instructed to fill out real-time design diaries for five weeks. This paper presents a preliminary model of the types of searches carried out, based upon the analysis of the diaries completed by five designers.

Baxter W, Aurisicchio M, Childs PRN, Tear Here: the Impact of Object Transformations on Proper Disposal, IAPRI 20th World Conference on Packaging
Efforts promoting proper disposal of packaging generally focus on infrastructure and messaging. Significantly less attention has been given to how the attributes of packaging can be used to change disposal behaviour. This research shows how changes in packaging attributes (e.g. alterations in shape, colour, or size) influence two disposal behaviours: recycling and littering. Specifically, we use an implicit association test to measure the subconscious tendency to categorize altered objects as trash rather than recycling. The results indicate that 82% or respondents showed at least a slight effect and 53% showed a strong effect towards associating altered objects with waste. Next, we evaluate object transformations on littering behaviour through an observational field study. Observations (N = 2823) indicated that littering is influenced by deformed, torn, disassembled, and partially full packaging. No significant effect was found with regard to packaging that is wet, sticky, has undergone colour changes or that is has remains (e.g. sauce) on it. These findings suggest that the (re)design of packaging can significantly influence proper disposal. Based on this, packaging can be (re)designed in two ways. First, many types of packaging have scripted alterations such as the iconic ‘tear here’ indicator. These can be changed to preserve properties associated with recyclables and non-littering. Second, packaging can be designed so that there are fewer alterations during use. This work can also help identify inherent attributes that encourage proper disposal.
Baxter W, Aurisicchio M, Mugge R, et al., Positive and negative contamination in user interactions, ICED17: 21st International Conference on Engineering Design, Publisher: Design Society
The purpose of this paper is to present contaminated interaction as a design construct. Interactions with an object can be altered,positively, neutrallyor negatively,due to some prior use. In such cases, the interaction departs from the designed condition and is said to be contaminated. This is particularly significant as objects, physical or non-physical, have multiple uses or are shared amongst users. We propose an ontological model of contaminated interaction based on a review of literature and an analysis of user experiences. The model outlines the process of contaminated interaction including the drivers and outcomes. In a negative context, contamination can lead to consumers misusing, negatively experiencing, or avoiding the object altogether. Positive contamination sees the opposite effect in which usability can increase, users report more positive experiences and users seek out or cherish the object. Together, this model presents an approach to understanding and addressing contamination in the design process to enable the creation and maintenance of meaningful experiences.
