Active video gaming linked with higher energy expenditure in children

  • PDF
TechAndComputer (Sep. 24, 2012) — Compared with rest and sedentary video game play, active video gaming with dancing and boxing were associated with increased heart rate, oxygen uptake and energy expenditure in a study of 18 school children in England, according to a report published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.

Low levels of physical activity have been linked to obesity. Active video game playing compared with traditional sedentary video game playing encourages more movement and could help children increase their physical activity levels, according to the study background.

Built-in germanium lasers could make computer chips faster

  • PDF
TechAndComputer (Sep. 10, 2012) — Paul Scherrer Institute (PSI) researchers have investigated how they could make the semiconductor germanium emit laser light. As a laser material, germanium together with Silicon could form the basis for innovative computer chips in which information would be transferred partially in the form of light. This technology would revolutionise data streaming within chips and give a boost to the performance of electronics. The researchers have demonstrated that...

Towards computing with water droplets: Superhydrophobic droplet logic

  • PDF
TechAndComputer (Sep. 7, 2012) — Researchers in Aalto University have developed a new concept for computing, using water droplets as bits of digital information. This was enabled by the discovery that upon collision with each other on a highly water-repellent surface, two water droplets rebound like billiard balls.

Can videogaming benefit young people with autism spectrum disorder?

  • PDF
TechAndComputer (Sep. 5, 2012) — According to the Centers for Disease Control and Prevention (CDC), 1 in 88 children in the U.S. has autism spectrum disorder (ASD), a broad group of neurodevelopmental disorders. Children and adolescents with ASD are typically fascinated by screen-based technology such as video games, and these can be used for educational and treatment purposes, as described in an insightful Roundtable Discussion published in Games for Health Journal: Research Development...

Scanning for drunks with a thermal camera

  • PDF
TechAndComputer (Sep. 4, 2012) — Thermal imaging technology might one day be to identify drunks before they become a nuisance in bars, airports or other public spaces. Georgia Koukiou and Vassilis Anastassopoulos of the Electronics Laboratory, at University of Patras, Greece, are developing software that can objectively determine whether a person has consumed an excessive amount of alcohol based solely on the relative temperature of different parts of the person's face.
