Extensive research in the field of ambient assisted living (AAL) provides profound knowledge about the design of AAL systems. However, more generic design characteristics for user interaction have not been formalized for this domain yet. Thus, we propose to develop a domain specific taxonomy for the design of user interaction in AAL systems. We adopted a(More)
Due to recent development of TVs in the direction of highly interactive multimedia platforms, interactive TV (iTV) applications gain popularity. In terms of control possibilities a variety of input modalities have become available, though effects on performance and user experience of different age groups when controlling different iTV applications remain(More)
Understanding human attention in mobile interaction is a relevant part of human computer interaction, indica-ting focus of task, emotion and communication. Lack of large scale studies enabling statistically significant re-sults is due to high costs of manual penetration in eye tracking analysis. With high quality wearable cameras for eye-tracking and Google(More)
