Abstract
Multi-touch tables provide a high-level collaborative workspace for multiple users around a physical surface. Users sit and work together to perform different tasks. There is no intermediate device between the users and tablet. Users can select and manipulate digital contents using fingers gestures and virtual keyboards. Virtual keyboard still have limitations that can adversely affect the quality and speed of typing on multi-touch table. For multi-touch tablets, small keys and a lack of tactile feedback make text entry with a virtual keyboard difficult, and the zoom and rotation properties exacerbate the problem. Inserting text quickly and accurately is still a challenge on a multi-touch-table. Our paper introduces a new virtual keyboard design, MT-TYPEHEX, which overcomes some of these limitations, increases the efficiency of human interaction with touch screens, and improves performance and productivity in cooperative work. After describing the MT-TYPEHEX, we will make a comparative study between a conventional virtual keyboard (QWERTY) and the MT-TYPEHEX keyboard by conducting experiments to evaluate their performance and error rates. We will also evaluate the user experience by administering questionnaires. From the final results of this comparative study, we will determine which keyboard is the most effective.
