Attainment Switch is a switch emulation program designed for used by individuals with cognitive, fine motor or upper extremity disabilities. This application (or app) allows a person to use their Apple iPad, iPhone or iPod Touch as a wireless accessibility switch. Attainment Switch can be used to communicate with scanning-enabled software running on any computer running the Mac or Windows operating system. The user can select from either one-button or two-button switch mode and use the app's built-in images or use his or her own images for each button. The program supports the .png image format for pictures, and the sound can be turned on and off. The user needs to download the free Switch Helper Application to his or her computer to configure the interface. The Windows and Mac drivers for this app are available at: http://switch.attainmentsoftware.com. A wireless network connection to that computer (either via a wireless router or an ad hoc connection) is also needed. COMPATIBILITY: For use with the Apple iPad, iPhone, or iPod Touch. SYSTEM REQUIREMENTS: Apple iOS 3.1.3 or later.
