Buttonless Clicking: Intuitive Select and Pick-release Through Gesture Analysis
any interaction input system must provide clicking as the basic functionality. Such a feature is is often difficult to provide in 3D input devices. Here, the tasks of selection, and pick-release is implemented t without any button-like feature. This method is based upon the trajectory and kinematic gesture analysis.
Functions like Pinch to grab must be provided by 3D glove. But the 3D trackers only have 6 degrees of freedom , as a result, it is difficul to implement in such areas. Some devices like Gametrak and the EyeToy , have gestures or voice recognition. In the method implenmented here, is is stated that the actions like selection, picking and releasing can be predicted based on the trajectory and kinematic patterns of the user’s hand. Here, the trajectory and kinematic patterns of users hand is tracked. picking starts the action and placing ends the action of positioning an object.
In the previous work done in 2D environments, the the dontclick project and implimentation allows to navigate a website without using mouse buttons. Here, when the cursor falls on an item , it is automatically selected. Other works have been done which uses 3D spatial gesture as a mean of interaction. keyboard stroke is combined using pen movement analysis by the shapewriter system .
