1.3 GESTURE BASED APPLICATIONS
Gesture based applications are broadly classified into two groups on the basis of their purpose: multidirectional control and a symbolic language. 3D Design: CAD (computer aided design) is an HCI which provides a platform for interpretation and manipulation of 3-Dimensional inputs which can be the gestures. Manipulating 3D inputs with a mouse is a time consuming task as the task involves a complicated process of decomposing a six degree freedom task into at least three sequential two degree tasks. Massachuchetttes institute of technology [3] has come up with the 3DRAW technology that uses a pen embedded in polhemus device to track the pen position and orientation in 3D.A 3space sensor is embedded in a flat palette, representing the plane in which the objects rest .The CAD model is moved synchronously with the users gesture movements and objects can thus be rotated and translated in order to view them from all sides as they are being created and altered. Tele presence: There may raise the need of manual operations in some cases such as system failure or emergency hostile conditions or inaccessible remote areas. Often it is impossible for human operators to be physically present near the machines [4]. Tele presence is that area of technical intelligence which aims to provide physical operation support that maps the operator 4 arm to the robotic arm to carry out the necessary task, for instance the real time ROBOGEST system [5] constructed at University of California, San Diego presents a natural way of controlling an outdoor autonomous vehicle by use of a language of hand gestures [1]. The prospects of tele presence includes space, undersea mission, medicine manufacturing and in maintenance of nuclear power reactors. Download 1.15 Mb. Do'stlaringiz bilan baham: |
