Abstract

A method and system of distinguishing multimodal HCI from ambient human interactions using wake up commands is disclosed. In one embodiment, in a method of distinguishing multimodal HCI from ambient human interactions, a wake up command is detected by a computing system. The computing system is then woken up to receive a valid user command from a user upon detecting the wake up command. A countdown timer is substantially simultaneously turned on upon waking up the computing system to receive valid user commands. The countdown timer is set based on application usage parameters such as semantics of the valid user command and context of an application associated with the valid user command.

Claims

1. A method of distinguishing multimodal HCI from ambient human interactions using wake up commands, comprising:

detecting a wake up command by a computing system;

waking up the computing system to receive a valid user command from a user upon detecting the wake up command; and

substantially simultaneously turning on a countdown timer upon waking up the computing system to receive valid user commands.

2. The method of claim 1, wherein the wake up command includes a user tap on the computing system when the user is up-close to the computing system.

3. The method of claim 1, wherein the wake up command includes a user gaze on a specific location of a screen of the computing system when the user is at-a-distance from the computing system.

4. The method of claim 1, wherein the wake up command includes a user tap on the computing system and a user gaze on a specific location of a screen of the computing system.

5. The method of claim 1, wherein the countdown timer is set based on application usage parameters selected from the group consisting of semantics of the valid user command and context of an application associated with the valid user command.

6. The method of claim 1, further comprising:

receiving valid user commands by the computing system until the countdown timer is active.

7. The method of claim 6, further comprising:

computing system going to a sleep mode when the countdown timer is not active; and

waking up the computing system again upon detecting a subsequent wake up command substantially around the computing system from the user.

8. A non-transitory computer-readable storage medium for distinguishing multimodal HCI from ambient human interactions using wake up commands having instructions that, when executed by a computing system, cause the computing system to perform a method comprising:

detecting a wake up command by the computing system;

waking up the computing system to receive a valid user command from a user upon detecting the wake up command; and

substantially simultaneously turning on a countdown timer upon waking up the computing system to receive valid user commands.

9. The non-transitory computer-readable storage medium of claim 8, wherein the wake up command includes a user tap when the user is up-close to the computing system.

10. The non-transitory computer-readable storage medium of claim 8, wherein the wake up command includes a user gaze on a specific location of a screen of the computing system when the user is at-a-distance from the computing system.

11. The non-transitory computer-readable storage medium of claim 8, wherein the countdown timer is set based on application usage parameters selected from the group consisting of semantics of the valid user command and context of an application associated with the valid user command.

12. The non-transitory computer-readable storage medium of claim 8, further comprising:

receiving valid user commands by the computing system until the countdown timer is active.

13. The non-transitory computer-readable storage medium of claim 12, further comprising:

computing system going to a sleep mode when the countdown timer is not active; and

waking up the computing system again upon detecting a subsequent wake up command substantially around the computing system from the user.

14. A system for distinguishing multimodal HCI from ambient human interactions using wake up commands, comprising:

a processor;

a wake up command detector; and

memory operatively coupled to the processor, wherein the memory includes a wake up command module having instructions capable of;

detecting a wake up command by the wake up command detector;

waking up a computing system to receive a valid user command from a user upon detecting the wake up command; and

substantially simultaneously turning on a countdown timer upon waking up the computing system to receive valid user commands.

15. The system of claim 14, wherein the wake up command detector is selected from a group consisting of a touch sensor and a gaze tracking device.
