摘要

Many children with motor impairments cannot participate in games and jokes that contribute to their formation. Currently, commercial computer games there are few options of software and sufficiently flexible access devices to meet the needs of this group of children. In this study, a peripheral access device and a 3D computerized game that do not require the actions of dragging, clicking, or activating various keys at the same time were developed. The peripheral access device consists of a webcam and a supervisory system that processes the images. This method provides a field of action that can be adjusted to various types of motor impairments. To analyze the sensitivity of the commands, a virtual course was developed using the scenario of a path of straight lines and curves. A volunteer with good ability in virtual games performed a short training with the virtual course and, after 15 min of training, obtained similar results with a standard keyboard and the adapted peripheral device. A 3D game in the Amazon forest was developed using the Blender 3D tool. This free software was used to model the characters and scenarios. To evaluate the usability of the 3D game, the game was tested by 20 volunteers without motor impairments (group A) and 13 volunteers with severe motor limitations of the upper limbs (group B). All the volunteers( group A and B) could easily execute all the actions of the game using the adapted peripheral device. The majority positively evaluated the questions of usability and expressed their satisfaction. The computerized game coupled to the adapted device will offer the option of leisure and learning to people with severe motor impairments who previously lacked this possibility. It also provided equality in this activity to all the users. (C) 2014 Published by Elsevier Ireland Ltd.
