The "Simple Sound Switch" from tfh (about £65) pictured above enables a person to get an extra switch input from making a loud enough sound. This is great for people who don't get along with speech recognition software such as Dragon Naturally Speaking and Voice Activated Commands but have enough control to make a deliberate loud sound/word.
Accessible Gaming pioneer, Colin McDonnell helped us test this out at SpecialEffect last week with a couple of driving games (pictured below with Wii-U Mario Kart 8). We had it set so you could shout to stop/start the kart, and a head-switch would alternatively steer left/right. It takes practice to get good at it, but just having that one extra input at your disposal means more games can be made accessible. We're looking to develop this further to give more power with sound duration and volume too. The OneSwitch Pulse system will mean that all the menus can be made accessible too.
This was the first time in a while that Colin had been able to drive in a console game. Some really nice ones to consider down the line (using the OneSwitch Pulse system) are Xbox One Forza Horizon 2 and on the Xbox 360/PS3, Driver San Francisco, Blur and Burnout Paradise. Colin and friends are looking to raise money for SpecialEffect at their William Merritt fund-raising page. If you can spare a few quid, please pop by and give them some support for their marathon gaming event.
