TIC-TAC has been designed to aid the understanding and management of the concept of time in people with autism and/or intellectual disability, who may have related perceptive and/or sensorial problems. It consists of an alternative system for representing time, devised for use while waiting, to indicated available leisure time, the time remaining for completing a task, or in situations which may result in sensory overload or other situations considered useful.
TIC-TAC consists of a series of supports to make time visible, audible and tangible. It makes it possible to visualize the duration and passing of time in a visual way, accompanied with pictograms or images to identify the activity underway or a period of waiting. The TIC-TAC tool has been devised to be used for waiting periods, free time, working and at times of sensory overload.
