Serious Games for Mental Health: Are They Accessible, Feasible, and Effective? A Systematic Review and Meta-analysis

Abstract: The development and use of serious games for mental health disorders are on the rise. Yet, little is known about the impact of these games on clinical mental health symptoms. We conducted a systematic review and meta-analysis of randomized controlled trials that evaluated the effectiveness of serious games on symptoms of mental disorder. Method: We conducted a systematic search in the Pubmed, PsycINFO and Embase databases, using mental health and serious games related keywords. Ten studies met the inclusion criteria and were included in the review, nine were included in the meta-analysis. Results: All of the serious games were provided via personal computer, mostly on CD-ROM without the need for an internet connection. The studies targeted age groups ranging from 7 to 80 years old. The serious games focussed on symptoms of depression (n = 2), post-traumatic stress disorder (n = 2), autism spectrum disorder (n = 2), attention deficit hyperactivity disorder (n = 1), cognitive functioning (n = 2) and alcohol use disorder (n = 1). The studies used goal-oriented (n = 4) and cognitive training games (n = 6). A total of 674 participants were included in the meta-analysis (380 in experimental and 294 in control groups). A meta-analysis of nine studies comprising ten comparisons, using a random effects model, showed a moderate effect on improvement of symptoms (g = 0.55 [95% CI 0.28 to 0.83]; P < 0.001), favoring serious games over no intervention controls. Discussion/Conclusion: Though the number of studies in the meta-analysis was small, these findings suggest that serious gaming interventions may be effective for reducing disorder related symptoms. More studies are needed in order to attain deeper knowledge of the efficacy for specific mental disorders and the longer term effects of this new type of treatment for mental disorders.

Security device for controlling the access to a personal computer or to a computer terminal

Abstract: The mouse of the computer is equipped with a reader of an access code located in one or a set of chipcards for users. The reader is connected to an antenna equipping the mouse so that the user has only to present his card to the mouse inside the influence zone of the antenna for obtaining that the access code is transmitted to the computer and that the security device rendering the computer inoperant is unlocked.

Computer controlled stage lighting system

Abstract: A stage or theatre lighting system having a plurality of multiple parameter lamp units each comprising means for producing a light beam having a plurality of adjustable parameters relating to beam characteristics and beam position; drive means for controlling a plurality of said parameters; lamp processor means for controlling said drive means; and lamp memory means for storing data and programs for execution by said lamp processor means; the improvement comprising said lamp memory means having non-volatile memory means for storage of all of said operating program and volatile memory means for storage of all lamp cue data; internal clock means; and command means to operably command said operating program to execute said stored cue data in a desired, pre-programmed time and sequence using said internal clock means. The system can work with a personal computer and does not need a remote control.
