## Abstract

In an example implementation according to aspects of the present disclosure, a method may include receiving, on a touch sensitive mat of a computing system, a touch input associated with a first event type. The method further includes determining whether to transform the touch input associated with the first event type to a different event type, and sending, to an application, the touch input associated with an event type based according to the determination.
