Hello, I have a 11 year old son with severe global devlopment issues due to his epilpesy. It is a challenge to get his attention to warn him of risks like stairs, tripping hazards, and also when we need him to look at us to give him instructions. I am thinking if I could build a device that vibrated like a pager or cell phone that is activated by a fob, or remote device. I could teach him to stop and look at us when he feels the vibration. I have seen devices for the deaf and blind, but they are hooked up to identify when a phone rings, lights are on, or a door bell rings. The device could be like pager or a small wrist device like a watch. The remote would be carried by the parent or care giver. I do not have an electronics background, so not sure where to start on this. Any help would be appreciated. Thanks Shaun [email protected]
