Haptic Glove

Abstract

The objective of our project is to make a “HAPTIC GLOVE” which is a wearable device that will provide tactile sensation through feedback of virtual objects. Elaborating it further, it is a normal wearable glove, which has a few sensors (primarily flex and force sensors) connected to the microprocessor, such that the movement of the hand reflected in the changing values of the sensors. The 3-D virtual objects are generated through MATLAB. Now the main aim is that when we now try and hold this virtual object, we can actually “feel” the object, which is not present in reality. If the object we are holding is say a sphere, after enclosing the sphere in the hand, we will not be able to close the hand completely, hence giving the effect of holding a real object. Although many people don't realize it, tactile feedback is as important as any of the other four major senses. It's not just about feeling a soft cloth or a furry pet, but the tactile sensations help us accomplish everyday tasks. Ever try tying your shoelaces while your hands are numb? Your hands haven't lost their dexterity, but without the tactile sensation, the task suddenly becomes a lot more difficult. We divided the project into three parts: software, hardware and interfacing. The MATLAB part consists of an MCU serial interface (to obtain object properties) and the 3-D objects created. To draw objects from basic 3D shapes as well as animate them in various ways. We use this as the visual feedback of our system where the user can see the object that he/she is holding, get information about the shape of the object and see it be picked up.
