Here's a a pilot being done at Children's Hospital Boston for cerebral palsy patients. The work is spearheaded by researchers at Spaulding Rehabilitation Hospital and Harvard School of Engineering and Applied Sciences looking to provide innovative therapy to kids with cerebral palsy. Being pilot and focused on kids, they've made it especially fun.
Microsoft Surface is a platform on which a variety of therapeutic apps can be developed depending on the type of cerebral palsy for which the child is receiving therapy. In this case, both direct interaction with hands and objects are used in the custom apps built by the team.
