Abstract

The present invention provides a time tracking device comprising a display incorporated into a housing of a projector, a control pad, and a power source. The time tracking device can provide a presenter with the ability to track the elapsed time of a presentation. The time tracking device is further capable of being projected onto a viewing screen using the light source and lens of the projector device. The device comprises a control pad which controls the functions of the timer device, such as on/off, start, stop, pause, reset, mode, illumination, and time of day. The present invention also provides a presentation timer comprising a presentation timer program module and an input control module operable for controlling timer functions associated with the presentation timer program module.
