Evolution of Game Controllers: Toward the Support of Gamers with Physical Disabilities

Video games, as an entertaining media, dates back to the \u201850s and their hardware device underwent a long evolution starting from hand-made devices such as the \u201ccathode-ray tube amusement device\u201d up to the modern mass-produced consoles. This evolution has, of course, been accompanied by increasingly specialized interaction mechanisms. As of today, interaction with games is usually performed through industry-standard devices. These devices can be either general purpose (e.g., mouse and keyboard) or specific for gaming (e.g., a gamepad). Unfortunately, for marketing reasons, gaming interaction devices are not usually designed taking into consideration the requirements of gamers with physical disabilities. In this paper, we will offer a review of the evolution of gaming control devices with a specific attention to their use by players with physical disabilities in the upper limbs. After discussing the functionalities introduced by controllers designed for disabled players we will also propose an innovative game controller device. The proposed game controller is built around a touch screen interface which can be configured based on the user needs and will be accessible by gamers which are missing fingers or are lacking control in hands movement

Does methylphenidate improve inhibition and other cognitive abilities in adults with childhood-onset ADHD?

Contains fulltext : 48908.pdf (publisher's version ) (Closed access)We examined the effect of methylphenidate (Mph) on inhibition and several other cognitive abilities in 43 adults with Attention Deficit Hyperactivity Disorder (ADHD) by use of Conners' Continuous Performance Test (CPT) and the Change Task (ChT), an extension of the Stop Signal Test (SST). In a double blind, cross-over, placebo controlled study with Mph, tests were administered during the third week of individually titrated treatment with Mph (maximum dose 1 mg / kg / day) and during the third week of treatment with placebo. We established large medication effects for commission errors, standard error of mean reaction time, and attentiveness on the CPT, as well as moderate medication effects for mean reaction time on the CPT and response re-engagement speed on the ChT. For Stop Signal Reaction Time (SSRT) on the ChT, we also established large effects of Mph, but only in a group of participants who showed slow SSRTs on placebo. Mph indeed ameliorates inhibition, which is the core problem of ADHD, and certain other cognitive abilities in adults with ADHD
