Abstract

A computing device can include a first enclosure and a display enclosure. A tag can be on the first enclosure. A sensor on the display enclosure can detect the tag location and generate sensor data. A controller can determine from the sensor data the relative position between the display enclosure and the first enclosure.

Claims

1. A computing device comprising:

a first enclosure;

a second enclosure;

an IR tag on the first enclosure;

an IR sensor on the second enclosure to detect an IR tag location on the first enclosure and generate IR sensor data; and

a controller to;

determine a restricted field of view from a field of view for the IR sensor;

determine a position of the first enclosure;

determine from the IR sensor data a relative position between the second enclosure and the first enclosure;

determine a gesture volume from;

the relative position between the second enclosure and the first enclosure; and

the restricted field of view for the IR sensor;

determine when an object within the gesture volume is providing a gesture; and

execute an instruction based on a provided gesture.

2. The device of claim 1, wherein the tag reflects IR light different than a material surrounding the tag.

3. The device of claim 1, further comprising a fastener to remove the second enclosure from the first enclosure when the second enclosure is attached to the first enclosure.

4. The device of claim 1, a hinge between the first enclosure and the second enclosure to adjust the second enclosure angle relative to the first enclosure.

5. The device of claim 1, wherein the sensor determines a location of a user'"'"'s hands.

6. The device of claim 1, wherein the second enclosure is a tablet computing device.

7. The device of claim 6, wherein the first enclosure is a docking station of the tablet computing device.

8. The device of claim 1, further comprising a code embedded in the tag that can be decoded by the controller.

9. The device of claim 1, wherein the tag includes an identifying code to uniquely identify the first enclosure.

10. The device of claim 1, wherein the tag indicates at least one of a manufacturer, model number, revision number, and country origin.

11. The device of claim 1, wherein determining a relative position between the second enclosure and the first enclosure comprises determining an angle between the first enclosure and the second enclosure.

12. The device of claim 1, wherein determining a relative position between the second enclosure and the first enclosure comprises determining a distance between the first enclosure and the second enclosure.

13. The device of claim 1, wherein determining a relative position between the second enclosure and the first enclosure comprises determining a skew between the first enclosure and the second enclosure.

14. A system comprising:

a computing device having a first enclosure and a second enclosure;

an IR sensor in the computing device to detect a tag location on the first enclosure and generate IR sensor data;

a controller in the computing device to;

determine a restricted field of view from a field of view for the IR sensor;

distinguish based on the tag, the first enclosure from other enclosures within the field of view of the IR sensor;

determine a position of the first enclosure;

determine relative position between the second enclosure and the first enclosure from the IR sensor data;

determine a gesture volume, which is above the first enclosure and in which user gestures are detected, from;

the relative position between the second enclosure and the first enclosure; and

the restricted field of view for the IR sensor;

determine when an object within the gesture volume is providing a gesture; and

execute an instruction based on a provided gesture.

15. The system of claim 14, wherein the first enclosure comprises a keyboard.

16. The system of claim 14, wherein the IR sensor determines a location of a user'"'"'s hands within the gesture volume.

17. The system of claim 14, further comprising a processor to determine when the object is providing a gesture.

18. A non-transitory computer readable medium comprising code that when executed by a controller of a computing device in an enclosure causes the controller to:

distinguish, based on a tag on a first enclosure, the first enclosure from other enclosures within the field of view of an IR sensor;

receive IR sensor data from the IR sensor;

determine an angle between the first enclosure and the second enclosure based on the IR sensor data;

determine an amount of skew between the first enclosure and the second enclosure based on alignment marks in the IR tag;

determine a position of the first enclosure;

determine a relative position of IR tags from the IR sensor data;

determine from the relative position of the IR tags an enclosure relative position between a second enclosure and a first enclosure;

determine a restricted field of view from a field of view for the IR sensor;

determine a gesture input volume, which is above the first enclosure and narrower than a field of view of the IR sensor, based on;

the relative position between the second enclosure and the first enclosure; and

the restricted field of view for the IR sensor;

determine when an object within the gesture volume is providing a gesture; and

execute an instruction based on a provided gesture.

19. The computer readable medium of claim 18 further comprising code that when executed causes a controller to:

execute an instruction related to a gesture detected in the gesture input volume by the IR sensor.
