Abstract
Example embodiments disclosed herein relate to determining a motion based on projected image information. Image information is projected onto an external surface from a device. Sensor information about the external surface and/or projection is received. Motion of the device is determined based on the sensor information.
Claims15
A method comprising:
- projecting image information onto an external surface from a mobile device;
- detecting information about the external surface using a sensor on the mobile device;
- determining distortion information based on the detected information;
- and
- determining an intentional movement pattern is associated with the distortion information.
2 more elements
A device comprising:
- a projection module to project image information onto an external surface;
- a sensor module to receive sensor information based on at least one of:
- the projected image information and the external surface;
- a projection correction module to stabilize the projected image information on the external surface based on the sensor information;
- an egomotion detection module to detect egomotion data from the sensor information;
- and
- an motion determination module to determine whether the egomotion data is associated with a motion pattern.
4 more elements
A non-transitory machine-readable storage medium storing instructions that, if executed by a processor of a mobile device, cause the processor to:
- cause a projector to project image information onto an external surface;
- receive sensor information describing at least one of:
- the projected image information and the external surface;
- determine spatial data from the sensor information;
- correct the projection based on the spatial data;
- and
- determine an intentional motion from the spatial data.
