Kanpur: IIT Kanpur has developed a novel touch-sensitive smart watch for the visually impaired and blind persons that are equipped with modern techniques and can be a boon for them. The watch has been developed at the National Centre for Flexible Electronics, IIT Kanpur by Prof. Siddhartha Panda, Department of Chemical Engineering, and Mr. Vishwaraj Srivastava.

Around 49 million blind and 285 million visually impaired persons in the world face difficulty in easily interacting with devices due to the absence of tactile interface. India is home to about 20% of the total blind people in the world. Addressing the concern, the team at IIT Kanpur has developed a smart watch that operates in haptic mode. Haptics deals with the technology that stimulates the sense of touch.

Prof. Abhay Karandikar, Director IIT Kanpur, said, “One of our objectives at IIT Kanpur has been to make innovations inclusive for all. This haptic smart watch is a significant invention in this regard, which I believe will be of great help for the blind and the visually impaired. The touch-sensitive and vibration-based features would prove to be revolutionary in giving the sense of time to the blind and the visually impaired. I congratulate the team led by Prof. Siddhartha Panda, and Mr. Vishwaraj Srivastava, for this invention.”

The invention is a cost-effective smart wearable device with a touch-sensitive tactile interface that displays information using vibrations. This makes it more suitable for private usage compared to audio-based output devices available in the market.

The dial face consisting tactile touch-sensitive hour markers and vibration-based output is used to read time, create an interface to select different apps, haptically recognize different apps, and to sense the numbers.

The watch comprises of sensors like PPG (Photoplethysmography) to read health parameters such as the heart rate and SpO2. An accelerometer is used to measure the step count to keep track of daily activity. All these parameters can be individually read using the haptic menu.

The developed watch has a special feature called a “smart timer” which is used to set short timers using a simple and unique gesture.

Indian Institute of Technology, Kanpur, is one of the premier institutions set up by the Government of India. Registered in 1959, the institute was assisted by nine leading institutions of the U.S.A in the setting up of its academic programs and laboratories during the period 1962-72. With its record of path-breaking innovations and cutting-edge research, the institute is known the world over as a learning center of repute in engineering, science, and several interdisciplinary areas. In addition to formal undergraduate and postgraduate courses, the institute has been active in research and development in areas of value to both industry and government.
