    Abstract:

Applications: A wearable device for assisting a visually impaired user is disclosed. The device includes a head-mounted image acquisition device to capture an image of a scene, a wearable computing device to track the visually impaired users hand and fingers coordinates and to construct one or more virtual objects, a haptic glove which includes a controller to receive spatial information of one or more tracked coordinates when the real-time spatial position of the fingers of the visually impaired user overlaps with the one or more virtual objects, to generate a braille code on demand and activate the refreshable braille cell in order to display the character, commanded by the wearable computing device in tactile form, a tactile element to generate a haptic output for indicating reception of a produced detection signal, to provide a sensation of a presence of the virtual object in front of the visually impaired user.
Advantages: 1. The device includes a head mounted image acquisition device mounted on a wearable computing device. The head mounted image acquisition device is configured to capture an image of a scene in front of the visually impaired user. 2. The wearable computing device is configured to obtain a real-time spatial position of fingers of the visually impaired user tracked using the head mounted image acquisition device. The wearable computing device is also configured to construct a virtual screen with one or more virtual objects in a memory. 3. The device also includes a haptic glove which includes a controller operatively coupled to the wearable computing device. The haptic glove includes a marker that enables the head mounted image acquisition device to track, deflection sensors to detect deflection of fingers, accelerometer and gyro-sensor to detect the spatial orientation of hand of the visually impaired user. The haptic glove also includes a controller configured to generate a braille code corresponding to the received information from the wearable computing device and display it on a refreshable braille cell.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
