MARIN-LAMELLET et al, 1999. Overview of validated recommendations for evaluation of ATT system with respect to E & D: A methodology for travellers who are elderly and disabled. CEC Transport Telematics Project TR1108, TELSCAN.
The specific objective in WP04 activity 4.1 is to provide help to Telematic Application designers to define and to complete assessment of the usability of systems with integration of potential users with disabilities or who are elderly.
The first level of the assessment methodology framework is related to the definition of the users to be involved in the usability assessment. To this end TELSCAN proposed three indicators :
• The mobility indicator
• The problem indicator
• The extent indicator
These indicators have to be analysed and tailored according to different considerations best accomplished by way of a brainstorming session.
The second level of the framework is related to the choice of the testing environment and context, as some of them could be more suitable or unsuitable to persons with disability or who are elderly.
In the third level, the framework provided guidelines in order to choose the methods/tools which will be the more suitable for use with the persons with disability or who are elderly as well as protocols or ethical issues which need to be considered.
Some information are also provided on the analysis of the results procedure and two cases studies are given in order to illustrate the framework.
