Design of Intangible Interface for Mouseless Computer Handling using Hand Gestures

AbstractIn this paper, an approach for developing an intangible interface with the help of computer vision technology for human computer interaction using static hand gestures has been discussed. Mouse operations like left click, right click and double click are performed by hand gestures. An image of the human hand is read from the webcam and the hand is segmented to obtain a binary image. The contour of the binary hand image is extracted to draw the convex hull around it as an envelope. The static hand gestures developed make use of feature extraction method. The developed system is compatible with a diverse group of users. It is a fast learning method and does not require extensive training of data facilitating low computational speed and cost. The main aim is to improve the interaction of human with the computer i.e. to make it more natural but keeping the cost factor in mind
