TASK PERFORMANCE BASED ON LOCATION

A task performance system and method including multiple transmitters and multiple task devices distributed in a local area. Each task device includes communication circuitry, a memory, a controller, and output circuitry. The communication circuitry receives timing information and position information from the transmitters. The transmitters may also transmit task information including task location parameters that define the task area. The task area is divided into subblocks each having a corresponding task value. The controller uses the received information to determine its location and accesses the memory when located within the task area to retrieve a corresponding task value based on subblock location. The task information includes task values which may define a different task for each subblock. The controller activates output circuitry in accordance with the task value to perform a corresponding task. The output circuitry may include one or more light sources, a speaker, a vibration device, etc.
