Merryweather’s TheTetra Universal Controller Showcased at CES 2017
January 9, 2016
Four teams from the University of Utah presented new technologies at this month’s Consumer Electronics Show in Las Vegas, three of which include faculty from the College of Engineering. Nick Swisher, marketing and communications manager, Technology and Venture Commercialization, and Brooke Adams, communications specialist with the University Marketing and Communications, profile the teams in the U’s campus newsletter.
Four innovative University of Utah technologies will be exhibited at Consumer Electronics Show (CES) 2017, the world’s largest and best-known technology trade show. The event ran from Jan. 5-8 in Las Vegas. It marked the U’s third consecutive year at the event—and largest representation yet. CES, which attracted more than 177,000 visitors and 3,800 exhibitors from around the world last year, introduces next-generation innovations to the marketplace.
“We look forward to our expanded involvement at CES 2017,” said Keith Marmer, executive director of Technology and Venture Commercialization at the U. “It’s likely that only a small portion of the products on display at CES would even exist if it weren’t for the innovations developed and research performed at universities. It is an excellent opportunity for us to showcase the kinds of technologies that may possibly be the future of consumer electronics.”
All four of the U’s technologies at CES offered demonstrations to attendees and the press. The technologies on exhibit included:
TheTetra Universal Controller
TheTetra Universal Controller is a device that greatly expands the number of input commands to individuals with quadriplegia/tetraplegia who use “sip and puff” systems to control mobility devices. Traditional systems typically only recognize changes in pressure. A hard puff, for instance, might enable a wheelchair to move forward, while a soft sip might stop the wheelchair. The ability to perform complex actions or sequences in these current systems is significantly limited. TheTetra Universal Controller combines pattern recognition, timing and pressure intensity which allows for a virtually unlimited number of control directives. Complex sequences can thus be programmed, enabling multistep movements or operations that will give users more control and independence over their lives. The enhanced ability to utilize complex input commands also enables the control of various household and office electronics (e.g., televisions, thermostats, lighting, doors, windows, etc.). It is even used to control both physical and virtual adaptive skis and kayaks.
TheTetra Universal Controller was developed by Jeffrey Rosenbluth, associate professor, physical medicine and rehabilitation and medical director of the Spinal Cord Injury Acute Rehabilitation program; Ross Imburgia, research engineer, Division of Physical Medicine and Rehabilitation; and Andrew Merryweather, assistant professor, mechanical engineering.
Adaptive Glasses are smart lenses that in less than a fiftieth of a second automatically put into focus what a user is looking at, whether that object is at a distance or up close. These liquid lenses use a tiny laser and a small amount of electricity to autofocus. They are controlled by an electronic actuator that compresses or stretches the lens based on what the wearer is looking at, thus providing a variable aperture. The glasses work in a similar way to bifocal spectacles in that they provide the user with a range of focus beyond that of traditional eyewear. They are, however, more versatile than bifocals or multifocal glasses as they possess the same function of having focus and different depths without becoming blurry in the other sections of the lenses. The Adaptive Glasses were developed by these members of the U’s Department of Electrical and Computer Engineering: Carlos H. Mastrangelo, professor; Nazmul Hasan, graduate research assistant; and Hanseup Kim, associate professor.
UPlay Piano is an interactive, web-based instructional software program for teaching young children how to play the piano. Each lesson contains an engaging and beautifully illustrated story to introduce new concepts, demonstrations and game sections to teach theory and musicianship, piano pieces for practice and a test to reinforce knowledge of concepts. The program employs a MIDI link to allow students to interact with the online website while playing on any electronic keyboard. The platform will also include an online database allowing parents and teachers to track student progress. UPlay Piano was developed by these members of the U’s School of Music: Lindsey Wright, associate instructor; Susan Duehlmeier, professor; and Cassandra Olsen-Taylor, adjunct assistant professor. Jared A. Pierce, assistant professor of the BYU School of Music and a U alumnus, also was part of the project team.
The Sentinel 100 is a board and chipset based on the work of Cynthia Furse, associate vice president for research and professor in electrical and computer engineering, that enables engineers, original equipment manufacturers, equipment manufacturers and system operators the ability to monitor electrical systems for detection and location of critical faults in live electrical wires when embedded into a product. The credit card-sized board also allows system operators to collect valuable baseline data that can be used to help predict and prevent outages.
