User-Evaluated Gestures for Touchless Interactions from a Distance

Very big displays are now commonplace but interactions with them are limited, even poorly understood. Recently, understanding touch-based interactions have received a great deal of attention due to the popularity and low costs of these displays. The direct extension of such interactions, touch less interactions, has not. In this paper we evaluated gesture-based interactions with very big interactive screens to learn which gestures are suited and why. In other words, did ‘Minority Report’ get it right? We aim to discover to which extend these gesture interfaces are technology-driven and influenced by prototyped, commercial and fictive interfaces. A qualitative evaluation of a gesture interface for wall sized displays is presented in which subjects experienced the interface while completing several simple puzzle tasks. We found that simple gestures based on the act of pressing buttons was the most intuitive.\ud \u

HTML5 Based Email Client with Touch Enabled Advanced User Interface for Tabs and Tablets

The Internet has become as a very powerful platform that has changed the way we do business and the way we communicate. E-Mail is an essential tool for both cooperative world and individuals for communicating. Web-based e-mail systems have become more popular among the internet users with time. Internet and the devices that we use to access the internet are rapidly changing time to time. Among the recent evolutions the most significant of them is HTML5 incorporated mobile technology with hi-tech devices like tabs, iPads and tablets with touch sensitivity. However, the major problem occurs when different levels of resolutions arisewithmodern devices. Some devices support touch, multi-touch, gestures, keyboards and stylus. User-interface of email web clients hasnt improved in the way hi-tech devices evolved. Handling different types of interactions depends on the device and way that user handles it. We have developed HTML5 off-line supporting web-based UI for e-mail system to overcome this issue and to provide a highly user based interactive, responsive and efficient process even in slow network connections. Our approach is based on HTML5 features and client side on java-scripting. Our system is capable of running on a browser without installing any plug-ins. Depending on the device resolution and user interaction (one finger touch/ both hands or external keyboard) email client has provisions to transform the web UI to give better interaction for the user and email system
