What do we mean by ‘Odd’ Behaviour for Seizure Detection?

About Benjamin

Benjamin is very autistic, and has profound learning difficulties, so we are trying to detect behaviour that is ‘odd’ for Benjamin.    This means sitting still for an extended period (he rarely says still) or sitting or lying in unusual postures – but he often lies on his bed in a different directions etc.

Below are examples of normal and odd behaviour.   He will not do things on demand, so I have had to dress as Benjamin and simulate some of them….
