Assessing Online-form Complexity for the Development of Assistive Technologies for Older Adults

Although cognitive declines occur as a natural product of the ageing process, the majority of online-forms do not cater specifically for the needs of older adult users. As a consequence, online-forms pose significant usability challenges to this target user group. The Delivering Inclusive Access to Disabled and Elderly Members of the community (DIADEM) project aims to develop a plug-in to a web browser that adapts existing online-form content so that it is more accessible and usable for older adults with cognitive decline. In order to identify requirements for developing the DIADEM application, it is necessary to observe users interacting with online-forms, and identify the usability challenges that occur as a result of this. However, the format and functionality of online-form content presented on the web varies greatly. Identifying a representative sample of online-forms that may be presented to users within a trials setting to elicit key usability challenges, has proved to be a non-trivial task. Consequently, we have developed a set of Bespoke Online-form Selection (BOFS) criteria which are used to help identify appropriate and representative candidate online-forms that may be used within the user trials setting to formulate initial requirements for developing the DIADEM application. In the context of the DIADEM project, BOFS has proved to be a valuable tool which has been used to successfully identify online-forms for use in our user trials. This paper presents the BOFS criteria, and shows how these are aligned with cognitive declines that are typically presented by the older adult user group, and demonstrates how BOFS has been of value within the context of the DIADEM project.</p

Towards a practical framework for managing the risks of selecting technology to support independent living

Information and communication technology applications can help increase the independence and quality of life of older people, or people with disabilities who live in their own homes. A risk management framework is proposed to assist in selecting applications that match the needs and wishes of particular individuals. Risk comprises two components: the likelihood of the occurrence of harm and the consequences of that harm. In the home, the social and psychological harms are as important as the physical ones. The importance of the harm (e.g., injury) is conditioned by its consequences (e.g., distress, costly medical treatment). We identify six generic types of harm (including dependency, loneliness, fear and debt) and four generic consequences (including distress and loss of confidence in ability to live independently). The resultant client-centred framework offers a systematic basis for selecting and evaluating technology for independent living

Online form complexity assessment for developing assistive technologies

The DIADEM project aims to develop assistive web-based technologies, in the form of an Expert System (ES), to improve online services access for older adults faced with cognitive decline. Both during the initial analysis and during system trials it is necessary to observe users browsing and interacting with ‘complex’ online forms. However, establishing what constitutes a ‘complex’ online form for this target user group, proved to be somewhat of a challenge. Consequently we have developed a set of Bespoke Online Form Selection (BOFS) metrics, which have been used to inform the online form selection and categorising process. BOFS has proved to be a valuable tool to identify complex online forms for use in DIADEM’s end-user trials. This paper presents the BOFS metrics, shows how these are aligned with the target user group, and demonstrates how BOFS has been of value within the context of the DIADEM project
