In order to gain optimal usability, accessibility and acceptability, the PIA team conducted lab-tests of the user interfaces and general functionality of the PIA system. At the end of 2013 mock-ups (paper prototypes) of all parts of the system were available for the R&D team.
Field trials are organised to pilot the PIA system in real home environments. In addition to primary end-users, both formal and informal carers are engaged in PIA field trials.
For demonstration purposes, a mobile “PIA kit” has been developed. This kit can also be deployed to acquire end-user feedback in different dissemination contexts. The mobile kit contains:
- Large posters which illustrate home appliances in real size (e.g. microwave oven, washing machine, DVD player, etc.)
- NFC tags to be attached to posters.
- Tablet PCs to show a video clip.
