It’s a given that you can’t imagine life without a smartphone now; everything is becoming linked and you’ll see people frantically typing or swiping on their smartphones to make transactions or to close business deals.
In words of Kai Kunze, team member, ‘The tongue is a well-developed muscle capable of fine-grain movements – so we thought it should be good for control interactions.’ The intended users can be skiers and motorcyclists who can use their smartphone/device without employing their hands. The test phase of the device involved 6 volunteers who were connected to a pad that had 64 pressure sensing elements. The pad was placed on cheeks and six tongue gestures were tested which included; a click (push with tongue), swipe up, down, left and right. A total of 300 attempts were recorded with a recognition accuracy of 98%,
Professor Kunze said; ‘My personal motivation here was skiing. I like to check factors like my speed while on the slope, yet it’s quite cumbersome to take out a smartphone and use a touch-screen in the cold.’
