SmartWatch3-2

Researchers from the Max Planck Institute for Informatics  and Aalto University calculate the easiest way to interact by gestures of hand and fingers using a camera-based input device. Owing to recent achievements in computer vision, modern algorithms can recognize even multi-finger gestures in a video stream. The research groups around professors Oulasvirta and  Theobalt used…

touchbiomechanics

Although different types of touch surfaces have gained extensive attention in HCI, this is the first work to directly compare them for two critical factors: performance and ergonomics. Our data come from a pointing task carried out on five common touch surface types: public display (large, vertical, standing), tabletop (large, horizontal, seated), laptop (medium, adjustably…

coactivation2

We present a novel summarization of biomechanical and performance data for user interface designers. Previously, there was no simple way for designers to predict how the location, direction, velocity, precision, or amplitude of users’ movement affects performance and fatigue. We cluster muscle coactivation data from a 3D pointing task covering the whole reachable space of…

menuOptimizer-1

Menu systems are challenging to design because design spaces are immense, and several human factors affect user behavior. This paper contributes to the design of menus with the goal of interactively assisting designers with an optimizer in the loop. To reach this goal, 1) we extend a predictive model of user performance to account for…
