Abstract

Embodiments of the present invention provide a presentation device that is simple to control for managing time and providing presentation instruction to a host device to make a presentation. In one embodiment, a presentation device is controlled by a user for providing presentation instruction to a host device to make a presentation. The presentation device comprises a timer button configured to be activated by a user to select an end time for a presentation, wherein each time the timer button is activated, a time interval between a current time and the end time is increased by a preset time increment. A timer module is configured to determine the time interval between the current time and the end time for the presentation as time passes; and a display configured to display the time interval between the current time and the end time for the presentation as time passes.

Claims

1. A presentation device controlled by a user for providing presentation instruction to a host device to make a presentation, the presentation device comprising:

a timer button configured to be activated by a user to select an end time for a presentation, wherein each time the timer button is activated, a time interval between a current time and the end time is increased by a preset time increment;

a timer module configured to determine the time interval between the current time and the end time for the presentation as time passes; and

a display configured to display the time interval between the current time and the end time for the presentation as time passes.

2. The presentation device of claim 1 wherein the display is configured to display a countdown of the time interval to the end time to show time remaining for the presentation.

3. The presentation device of claim 1 further comprising a remaining time alert module configured to alert the user of a preset remaining time to the end time.

4. The presentation device of claim 3 wherein the remaining time alert module is configured to alert the user of a first preset remaining time to the end time and a second preset remaining time to the end time, the first preset remaining time being different from the second preset remaining time.

5. The presentation device of claim 3 further comprising a vibration member configured to produce a vibration at at least one of the end time and the preset remaining time to the end time.

6. The presentation device of claim 1 further comprising at least one of a next button to advance to a next presentation display, a previous button to retreat to a previous presentation display, a blank button to provide a blank display, a reset button to reset the timer module, a laser control button to control a laser pointer, a start/stop button to start/stop a slide show presentation, and a current time button to display a current time of an internal clock.

7. The presentation device of claim 1 further comprising a battery alert unit configured to provide notification when a battery level of a battery in the presentation device falls below a preset level.

8. The presentation device of claim 1 further comprising a wireless communication unit configured to provide wireless communication with a host device to make a presentation.

9. A presentation device controlled by a user for providing presentation instruction to a host device to make a presentation, the presentation device comprising:

a timer button configured to be activated by a user to select an end time for a presentation, wherein each time the timer button is activated, a time interval between a current time and the end time is increased by a preset time increment;

a timer module configured to determine the time interval between the current time and the end time for the presentation as time passes; and

a remaining time alert module configured to alert the user of a preset remaining time to the end time.

10. The presentation device of claim 9 wherein the preset remaining time to the end time is shorter than the preset time increment.

11. The presentation device of claim 10 wherein the remaining time alert module is configured to alert the user of a first preset remaining time to the end time and a second preset remaining time to the end time, the first preset remaining time being different from the second preset remaining time.

12. The presentation device of claim 10 further comprising a vibration member configured to produce a vibration at at least one of the end time and the preset remaining time to the end time.

13. A method of managing time for a presentation device used for providing instruction to a host device to make a presentation, the method comprising:

setting, at an initial current time, an initial time interval between the initial current time and an end time for a presentation in response to activation of a timer button;

determining the time interval between a current time and the end time for the presentation as time passes; and

displaying the time interval between the current time and the end time for the presentation as time passes,

wherein each time the time button is activated, the time interval between the current time and the end time is increased by a preset time increment.

14. The method of claim 13 wherein displaying the time interval comprises displaying a countdown of the time interval to the end time to show time remaining for the presentation.

15. The method of claim 13 further comprising providing a notification at a preset remaining time to the end time.

16. The method of claim 15 wherein providing the notification comprises providing a first notification at a first preset remaining time to the end time and providing a second notification at a second preset remaining time to the end time, the first preset remaining time being different from the second preset remaining time.

17. The method of claim 15 wherein providing the notification comprises producing a vibration.

18. The method of claim 13 further comprising wirelessly providing instruction from the presentation device to a host device to make a presentation.

19. The method of claim 13 further comprising providing instruction from the presentation device to a host device to make a presentation, the instruction including at least one of advancing to a next presentation display, retreating to a previous presentation display, and providing a blank display.

20. The method of claim 13 further comprising resetting the time interval between the current time and the end time for the presentation in response to activation of a reset button.
