Abstract:
Needs and wishes regarding the interaction with ICT solutions change over time and vary between older adults. They depend on the user’s physical and mental capabilities and preferences. In particular usability, accessibility, as well as the freedom of choice concerning the interaction with such systems are the crucial points for acceptability and applicability. The aim of the AALuis project is to offer a practical solution for adapting user interfaces and services to changing needs and wishes of older adults in a flexible way by providing various devices and I/O modalities. The paper describes the approach for the integration of an avatar into the generated user interfaces. The user interfaces aim to provide consistent look and feel for different services to interact using the user’s preferred modality. In the first development cycle, the focus was on covering the whole transformation process from abstract task descriptions to renderable UIs to be displayed on various I/O devices. First evaluations in a lab setting have been performed to detect usability issues. The participants gave very positive feedback about the identical layout of the application on different I/O devices, but nevertheless some usability issues have been identified. Solutions to tackle these issues are presented in this paper and especially the avatar integration will be a big step towards an increased acceptance of AAL services and their user interfaces.
