Future Work

1. Recently, the technology for supporting user friendly and intelligent interaction becomes very important as the computer technology advances and the complexity of information systems grows. • A good Multi-Touch gesture library becomes a core component of the information devices adopting dynamic touch surfaces. • Windows 7 supports multi-touch actions such as Rotate , Pan, Zoom in ,Zoom , out ,One and two finger tap. Aim • The aim of the project is to work with the Windows 7 driver and Adobe Flash to develop a series of gestures. • The basic gestures that need to be developed include one and two finger tap, swipe , flick, zoom in, zoom out and rotate. • 3-D gestures • This work can be extended to develop 3-D gesture library as well with the use Microsoft Kinect SDK. Multi-Touch Gesture Library Anoop Gunturi http://www.ceti.cse.ohio-state.edu/ Introduction Analysis and Design Figure 2: Transformation and Gesture Detection • Transformation Logic • The transformation logic watches input points and looks for changes in the points’ positions over time. • The logic changes an interactive object in the same way. • This is commonly termed “gesturing” even though it’s technically not • Gesture Detection • Gesture detection logic detects gestures based on point input stream and emits an event when a gesture has been detected. Library Design Overview The transformation logic can currently track up to two input points. When one of these points moves, the logic transforms the object based on the differences between the line the points used to form and the line the points currently form. Figure 3: Transformation Logic Work Done So far • Transformation logic has been implemented and the interactive object can be moved , rotated and scaled. • The interactive object can work with both Touch and Mouse Input. • Mouse can be used to only move the object. Future Work • Library Design • Implementing the gesture detection part of the gesture Library. • We need to be able to be able to do gesture detection and transformations based on input from either the mouse or the touch screen • 3-D gestures • 2D applications based on multi-touch input are now well known and accepted by the general public. • 3D content on multi-touch surfaces is not as mature. So, a lot of work can be done in this area. Figure 1: Library Design Overview Acknowledgements • A special thanks to Michael A.
