Mobile usage scenarios afford many completely different interactions, so should be designed accordingly. This paper presents a new type of widget, the T-Bar, designed specifically for finger-based touchscreen interfaces using tactile feedback. Using the tactile feedback for orientation, the user’s fingertip is guided along the T-Bar until an item is successfully selected. This paper offers observations on our finger-based touchscreen widget and two applications of the T-Bar widget. Both, File-o-Feel and Touch ‘n’ Twist are multi-touch information browsing applications that deviate from traditional desktop GUI paradigms and are tailored for fingertip input where all interaction takes place through the use of T-Bars; eliminating the need for any other widgets.</ABSTRACT><URL>http://www.dcs.gla.ac.uk/~stephen/papers/MobileHCI08_hall.pdf</URL></RECORD></RECORDS></XML>
