Finger-based touch input has become a major interaction modality for mobile user interfaces. However, due to the low precision of finger input, small user interface components are...
Retrieving the stylus of a pen-based device takes time and requires a second hand. Especially for short intermittent interactions many users therefore choose to use their bare fin...
TYPERIGHT is a new tactile input device for text entry. It combines the advantages of tactile feedback with error prevention methods of word processors. TYPERIGHT extends the stan...
