To search for objects in the murky waters of Japanese engineers offer with the help they have created innovative IrukaTact gloves with tactile feedback. During rescue operations specialists will be able to feel objects in the water even touching him. A gloved set of ultrasonic sonar MaxBotix, which is located on the inner wrist of the person. Reflected sonar signals pass through the onboard Arduino computer, which activates three micronesica installed on the fingers – at the expense of their work on the silicone fingertips being pressured. Thus, the closer the facility is located underwater to a specific finger, the stronger will be the pressure. It will help a person to “feel” the contours of objects lurking in the murky waters. Currently the area of operation of the sonar in IrukaTac does not exceed 0.6 meters, but the researchers continue their research, hoping to improve the glove and, in particular, to increase the range of its validity. Also according to the developers, their invention will find application in the growing field of virtual reality.
