Video game research project to help blind children exercise

01.06.2010
Exergames takes first steps to accessibility

VI Fit, a project at the University of Nevada, Reno, helps children who are blind become more physically active and healthy through video games. The human-computer interaction research team in the computer science and engineering department has developed a motion-sensing-based tennis and bowling exergame that can be downloaded for free at www.vifit.org.

"Lack of vision forms a significant barrier to participation in physical activity and consequently children with visual impairments have much higher obesity rates and obesity-related illnesses such as diabetes," Eelke Folmer, research team leader and assistant professor in the computer science and engineering department, said.

Exergames are a new type of video game that use physical activity as input and are considered powerful weapons in the fight against obesity. Unfortunately, exergames have not yet been accessible to children with visual impairments, although it is evident they could benefit from them the most.

"Our games are adaptations of the popular Nintendo Wii Sports exercise games that have been modified so they can be played without visual feedback," Folmer said.

VI Tennis and VI Bowling are the first of several games to be made available. VI Tennis implements the gameplay of Wii sports tennis providing audio and vibrotactile cues that indicate when to serve and when to return the ball. It can be played against the computer or against a friend using two Wii remotes.

"VI Tennis was evaluated at Camp Abilities in New York with 13 children who were blind," Folmer said. "We found our game to engage children into levels of active energy expenditure that were high enough to be considered healthy, which shows the feasibility of using video games as a health-intervention method."

The gameplay of Wii sports bowling is implemented through VI Bowling with a novel motor-learning feature that allows players to find the direction in which to throw their ball using vibrotactile feedback. Audio and speech effects are used to indicate the result of each throw. VI Bowling was evaluated with six adults and was found to yield levels of active energy expenditure that are comparable to walking.

Compared to the general population, individuals with visual impairments have even fewer opportunities to engage in physical activities that provide the amounts and kinds of stimulation needed to maintain adequate fitness and support a healthy standard of living. Folmer and his team are exploring alternative forms of interaction that allow individuals with visual impairments to play exercise games and to increase their participation in physical activity.

Folmer's team includes: Tony Morelli, a doctoral candidate at the University of Nevada, Reno; John Foley, a faculty member in the physical education department and expert in movement studies in disability at State University of New York, Cortland; and Lauren Lieberman, a researcher in the Department of Kinesiology, Sports Studies and Physical Education at SUNY, Brockport who specializes in adapted physical education, especially children with sensory impairments.

To play the VI Fit games, a user would need a Wii remote and a Windows PC with bluetooth support or a USB bluetooth dongle. The games can be downloaded using instructions at www.vifit.org. The games are not affiliated with or endorsed by Nintendo.

Nevada's land-grant university founded in 1874, the University of Nevada, Reno has an enrollment of nearly 17,000 students. The University is home to one the country's largest study-abroad programs and the state's medical school, and offers outreach and education programs in all Nevada counties.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
