Deaf individuals often experience communication difficulties in face-to-face interactions with hearing people. In order to support deaf individuals in such situations, an active stream of assistive technology (AT) research focuses on real-time translation of sign language. We investigate the impact of real-time translation-based ATs on communication quality(More)
In recent years, mid-air gestures have become a feasible input modality for controlling and manipulating digital content. In case of controlling TVs, mid-air gestures eliminate the need to hold remote controls, which quite often are not at hand or even need to be searched before use.

People who are affected by tremor often have difficulties when interacting with smartphones. The uncontrollable shaking of the hands can complicate fast and accurate interaction with touchscreen based smartphones. Although recent work has shown that motion sensors incorporated in smartphones can be leveraged for detecting tremor, little work has been done(More)
As the availability of smartwatches advances, small round touch-screens are increasingly used.

This paper presents a systematical comparison of pointing gestures in the context of controlling home appliances in smart homes. The pointing gestures were conducted with head, hand, arm and a computer mouse serving as baseline. To the best of our knowledge, we are the first to report on such a systematical comparison of the mentioned modalities. Our(More)
