Computer engineering students at The University of Alabama in Huntsville have designed a tool that could revolutionize new ways of using electronic devices with just one hand. It’s called a Gauntlet Keyboard, a glove device that functions as a wireless keyboard. Instead of tapping keys on a keyboard, the user simply touches their thumb to points on their fingers assigned a letter or other keyboard function.
Conductive thread carries the commands to a matchbox-sized Printed Circuit Board (PCB) affixed to the back of the glove. The PCB transmits it via Bluetooth, whether it’s a computer, a mobile phone, music synthesizer, video game or military device. Think of the Gauntlet as a touch screen that works by tapping your fingers to your thumb on a gloved hand.
Four senior engineering students at UAH made the glove their senior design project for a computer engineering class led by Dr. B. Earl Wells. The students — Jiake Liu, Stephen Doud, Douglas Kirby and Chris Heath — are now seeking a patent to market the product. The project recently won a $20,000 prize from the Best Buy Innovator Fund, beating hundreds of entries.
“It’s basically a keyboard on your hand,” explained Liu, the principal innovator and a graduate of Grissom High School. “You, by tapping your thumb on each segment of your fingers, type to the screen basically. And you can do a swiping gesture that would erase it.”
Gauntlet is an acronym for Generally Accessible Universal Nomadic Tactile Low-power Electronic Typist. That’s a lengthy description of what essentially is a glove with a beehive of conductive threads running throughout the fingers and palm.
Liu said the inspiration came from his interest in science fiction movies and experience with touch-screen technologies. Once he and his project partners came up with the idea, they did some scientific research on the most frequently used characters on a keyboard. Common keystrokes got the easiest finger-thumb alignments like the fingertips. Less common ones required more hand contortions to make the contacts. Until users memorize the new “key” positions, the characters are sewn into the finger and palm positions of the glove.
The students were assisted in their initial work by Huntsville electronics firm ADTRAN after entering it in the company’s senior design showcase. The company assisted largely with the micro soldering of the PCB parts. Liu said the group has been in contact with a patent lawyer and a specialty glove designer about going commercial with the Gauntlet.
The young designers are excited about the possibilities for the Gauntlet. “There are several applications we can think of right now,” Liu said. “The easy one would be as a keyboard for the consumer market. Also, the medical field for people limited to one hand from a disability. We can also think of military uses, as an entertainment device or used as a musical instrument for digital synthesizing.”
Dr. Emil Jovanov, associate dean for Graduate Education and Research in the UAH College of Engineering, commended the students for their innovation. “It is a perfect example of how you take an original idea, find your niche and complete the whole idea.” Jovanov said the project would be pitched to the Alabama Launch Pad, a competition to help fund and launch business plans.
