Abstract

Human machine interfaces that increase selectability and reduce distractibility of an operator controlling a system in a distracted operating environment are disclosed. A method can include receiving a first gesture on a pressure sensitive input device, and receiving a second gesture in temporal proximity to the first gesture on the pressure sensitive input device. The first and second gestures can be characterized by discretized time and pressure metrics. Additionally, the method can include selecting a control message from a plurality of control messages based on a combination of the first and the second gestures, and sending the selected control message to the system. A total number of control messages can be related to a number of each of the discretized time and pressure metrics for the first and second gestures. Additionally, the size of the discretized time and pressure metrics can be tuned to reduce distraction of the operator.

Claims

1. A method for increasing selectability and reducing distractibility when controlling a system in a distracted operating environment, comprising:

receiving a first gesture on a pressure sensitive input device, the first gesture being characterized by a discretized time metric and a discretized pressure metric;

receiving a second gesture in temporal proximity to the first gesture on the pressure sensitive input device, the second gesture being characterized by a discretized time metric and a discretized pressure metric;

selecting a control message from a plurality of control messages based on a combination of the first and the second gestures; and

sending the selected control message to the system.

2. The method of claim 1, further including providing active tactile feedback in response to at least one of receiving the first gesture, receiving the second gesture, or selecting the control message.

3. The method of claim 1, further including providing a sound in response to at least one of receiving the first gesture, receiving the second gesture, or selecting the control message.

4. The method of claim 1, wherein the selected control message is determined by a combination of the discretized time and discretized pressure metrics for the first and second gestures.

5. The method of claim 1, wherein the selected control message determines at least one of a magnitude and rate of system response.

6. The method of claim 5, wherein at least one of the magnitude or rate of the system response increases as at least one of the discretized pressure metric or the discretized time metric for at least one of the first and second gestures changes.

7. The method of claim 1, further comprising receiving a third gesture in temporal proximity to the first and second gestures on the pressure sensitive input device, the third gesture being characterized by a discretized time metric and a discretized pressure metric, wherein selecting a control message from a plurality of control messages is based on a combination of the first, second, and third gestures, and wherein a total number of control messages is related to a number of each of the discretized time and discretized pressure metrics for the first, second, and third gestures.

8. The method of claim 1, wherein the first and second gestures include at least one of:

approximately continuous contact with the pressure sensitive input device between at least two points;

contact with the pressure sensitive input device at approximately a single point;

or

approximately continuous contact for greater than a predetermined amount of time.

9. The method of claim 1, wherein the operating environment includes an in-vehicle system including at least one of an audio system, a media system, a navigation system, a lighting system, a heating and air conditioning system, and a cruise control system.

10. A system, comprising:

a pressure sensitive input device;

a memory; and

a processor in communication with the memory, the processor configured to;

receive a first signal corresponding to a first gesture received on the pressure sensitive input device, the first signal characterized by a discretized time metric and a discretized pressure metric;

receive a second signal in temporal proximity to the first signal, the second signal corresponding to a second gesture received on the pressure sensitive input device, the second signal being characterized by a discretized time metric and a discretized pressure metric;

select a control message from a plurality of control messages based on a combination of the first and the second signals; and

send the selected control message to a sub-system being controlled.

11. The system of claim 10, further including an active tactile feedback device configured to provide active tactile feedback in response to at least one of receiving the first gesture, receiving the second gesture, or selecting the control message.

12. The system of claim 10, further including a speaker configured to provide a sound in response to at least one of receiving the first gesture, receiving the second gesture, or selecting the control message.

13. The system of claim 10, wherein a total number of control messages is related to a number of each of the discretized time and discretized pressure metrics for the first and second signals.

14. The system of claim 10, wherein the selected control message is determined by a combination of the discretized time and discretized pressure metrics for the first and second signals.

15. The system of claim 10, wherein the selected control message determines at least one of a magnitude and rate of system response.

16. The system of claim 15, wherein at least one of the magnitude or rate of the system response increases as at least one of the discretized pressure metric or the discretized time metric for at least one of the first and second signals changes.

17. The system of claim 10, further comprising receiving a third gesture in temporal proximity to the first and second gestures on the pressure sensitive input device, the third gesture being characterized by a discretized time metric and a discretized pressure metric, wherein selecting a control message from a plurality of control messages is based on a combination of the first, second, and third signals, and wherein a total number of control messages is related to a number of each of the discretized time and discretized pressure metrics for the first, second, and third signals.

18. The system of claim 10, wherein the first and second gestures include at least one of:

approximately continuous contact with the pressure sensitive input device between at least two points;

contact with the pressure sensitive input device at approximately a single point;

or

approximately continuous contact for greater than a predetermined amount of time.

19. The system of claim 10, wherein the sub-system includes at least one of an audio system, a media system, a navigation system, a lighting system, a heating and air conditioning system, and a cruise control system.

20. A computer-readable medium comprising instruction which, when executed by a processor, perform a method comprising:

receiving a first gesture on a pressure sensitive input device, the first gesture being characterized by a discretized time metric and a discretized pressure metric;

receiving a second gesture in temporal proximity to the first gesture on the pressure sensitive input device, the second gesture being characterized by a discretized time metric and a discretized pressure metric;

selecting a control message from a plurality of control messages based on a combination of the first and the second gestures; and
