Audio feedback is provided by speech synthesis. The paper is organized as follows. Next we would analyze this task for identifying the gesture primitives and keywords which would encompass possible interaction modes. This will be followed by a study on ways of integrating the multiple modalities. It is our goal to achieve a perceptual user interface which will make it possible to perform complicated tasks with ease in an enhanced multimodal display control environment.
Further feedback is an important component of any natural interaction process.
Toward multimodal human-computer interface . Special issue on Multimedia Signal Processing. When we are tracking a human body, the shape is always subject to changes, the position is bound to change, and as the person moves in a 3 D environment, the lighting changes. All these need to be taken care of when we are tracking. In present form, our algorithm provides a solution to some of these problems.
