Visualising the number of people who cannot perform tasks related to product interactions

Understanding the number of people who cannot perform particular tasks helps to inform design decisions for mainstream products, such as the appropriate size and contrast of visual features. Making such informed decisions requires a dataset that is representative at the level of a national population, with sufficient scope and granularity to cover the types of actions associated with product use. Furthermore, visualisations are needed to bring the dataset to life, in order to better support comparing the number of people who cannot perform different tasks. The 1996/97 Disability Follow-up Survey remains the most recent Great British dataset to cover all types of ability losses that may be relevant to using everyday products. This paper presents new visualisations derived from this dataset, which are related to vision, hearing, cognition, mobility, dexterity and reach. Compared to previous publications on this dataset, the new visualisations contain task descriptions that have been simplified, described pictorially and separated out into different categories. Furthermore, two-dimensional visualisations are used to present exclusion results for products that require vision and/or hearing and for tasks that require each hand to do different things. In order to produce these new visualisations, the publicly available version of this dataset had to be reanalysed and recoded, which is described here-in detail.This is the author accepted manuscript.

Brand awareness of new technology in the introduction stage: A study of Blu-Ray vs HD-DVD format

The introduction of a new technology into the marketplace generally is a risky endeavour for a company, however, when there are competing new technologies of which it is believed only one can survive, winning over customers is one of the major corporate battles to be fought. This paper presents results of a survey among 1495 people regarding their awareness of the two DVD competing formats (Blu-ray and HD-DVD) in the early stages of the recent DVD format war. The results reveal that in the early stages of the format war more people were aware of the HD-DVD than of the Blu-ray format. A model is presented that predicts format awareness from four consumer characteristic constructs and four demographic variables

How preferences change after receiving new product information in an experimental choice task

Discrete choice experiments typically assume that preference structures remain stable over time and over multiple exposures to information about choice alternatives. However, this assumption may not be valid when the study concerns a new product, which individuals are less familiar with. This paper tests how attribute preferences shift when respondents are exposed to new product information in an experimental choice task. The findings indicate how attribute utilities vary across the before and after exposure conditions; further analysis however shows these effects to partly disappear when the effect of information on the scale constant is accounted for

Rational Vs Emotional Appeals with Communications to Landholders: A Review of Focus Group Responses

There are many organisations that seek to communicate with landholders for the purposes of engaging them in local environmental or conservation programs and sustainable production. This study examined whether different segments of landholders are likely to respond better to communication based on different appeals (rational or emotional), using different messages and communication channels. Seven hypothetical communication campaigns were designed with specific messages and appeals, each produced in three types of media. Focus groups of three specific landholder groups lifestylers., traditional and absentee landowners were held to obtain their responses to the campaigns. Findings suggest that the effectiveness of communications with landholders can be increased by using preferred messages and appeals, and selecting a combination of media appropriate to the landholder group being targeted
