System and method for identifying imminent dropping of a device and providing a warning of the imminent dropping

1. A processing system comprising:

an input device comprising one or more pressure sensors operable to sense pressure inputs from a user; and

a processing unit operable to identify an imminent dropping of the input device from measurements obtained by the one or more pressure sensors, and to affect a warning to the user when the processing unit identifies an imminent drop.

2. A processing system according to claim 1 , wherein the warning comprises one or more of an audible, a visual and a tactile component.

3. A processing system according to claim 2 , wherein the processing system is configured to cause an audible warning as the audible component to be output by one or more of the input device, the processing device or a display device.

4. A processing system according to claim 1 , wherein the input device is operable to perform an action to reduce a risk of damage being sustained by the input device in response to an identification of an imminent drop.

5. A processing system according to claim 1 , wherein the processing system is configured to cause the warning to be shown when a condition is met, the condition including one or more criteria selected from the list consisting of:

i. when pressure inputs fall below a threshold amount;

ii. when pressure inputs change by at least a threshold amount; and

iii. when pressure inputs change at a rate greater than a threshold amount.

6. A processing system according to claim 1 , further comprising a camera arranged to capture images of the input device and the user.

7. A processing system according to claim 1 , wherein the processing system is configured to cause the warning to be provided to the user in response to the user performing a predetermined motion in conjunction with a change in pressure inputs.

8. A processing system according to claim 1 , wherein the processing system is configured to cause the warning to be provided to the user only if the input device is greater than a threshold distance from a surface.

9. A processing system according to claim 1 , further comprising a head-mountable display.

10. A processing system according to claim 9 , wherein the warning comprises video content obtained using a camera associated with the head-mountable display.

11. A processing system according to claim 1 , in which the processing system further comprises a communication unit operable to receive inputs from the input device, the inputs corresponding to operation of the one or more pressure sensors, and

wherein the processing unit comprises a processor operable to generate, in dependence upon the received inputs, a warning to be provided to the user when a change in the sensed pressure is identified as being indicative of an imminent dropping of the input device.

12. The processing system of claim 11 , in which:

the communication unit is operable to receive inputs from the input device indicating an orientation of the input device; and

the processor is operable to generate the warning responsive to both the sensed pressure and the orientation of the input device.

13. A pressure-sensing method for use with an input device comprising one or more pressure sensors operable to sense pressure inputs from a user, the method comprising:

receiving, at a processing device, one or more inputs from the input device, the inputs corresponding to operation of the one or more pressure sensors;

identifying an imminent dropping of the input device from measurements obtained by the one or more pressure sensors; and

generating, in response to an imminent drop being identified, a warning to be provided to the user.

14. The pressure sensing method of claim 13 , further comprising:

receiving, at the processing device, one or more orientation inputs from the input device, the orientation inputs corresponding to the orientation of the input device;

wherein the identifying step comprises identifying the imminent dropping of the input device responsive to both measurements obtained by the pressure sensors and the orientation of the input device.

15. A non-transitory computer-readable recording medium having instructions stored thereon, the instructions, when executed by a computer, causing the computer to perform a method comprising:

receiving, at a processing device, one or more inputs from the input device, the inputs corresponding to operation of the one or more pressure sensors;

identifying an imminent dropping of the input device from measurements obtained by the one or more pressure sensors; and

generating, in response to an imminent drop being identified, a warning to be provided to the user.

16. The non-transitory computer-readable recording medium of claim 15 , wherein the method further comprises:

receiving, at the processing device, one or more orientation inputs from the input device, the orientation inputs corresponding to the orientation of the input device;

wherein the identifying step comprises identifying the imminent dropping of the input device responsive to both measurements obtained by the pressure sensors and the orientation of the input device.
