Power and processor management for a personal imaging system

A method of minimizing power resources of a personal imaging device regarding a user's interaction with an application on a mobile device, comprising the steps of:

• the personal imaging device capturing an image of a display of the mobile device;
• the personal imaging device analyzing the image of the display of the mobile device to detect a visual start signal within the image displayed on the display of the mobile device, wherein the visual start signal includes a trigger that activates any remaining inactivated sensors of the personal imaging device;
• the personal imaging device activating a processing and resource intensive program regarding the user's interaction with the application on the mobile device;
• the personal imaging device detecting a visual end signal within the image displayed on the display of the mobile device, ending the processing and resource intensive program;
• and
• the personal imaging device deactivating at least some of the sensors of the personal imaging device.

A computer program product for data collection by a personal imaging device regarding a user's interaction with an application on a mobile device, the personal imaging system comprising at least one processor, one or more memories, one or more computer readable storage media, a plurality of sensors, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by the computer to perform a method comprising:

• detecting, by the personal imaging device, movement of the user's head in a determined direction through a position sensor of the personal imaging device, the determined direction indicating the user looking at the mobile device;
• capturing, by the personal imaging device, an image of a display of the mobile device;
• analyzing, by the personal imaging device, the image of the display of the mobile device to detect a visual start signal within the image displayed on the display of the mobile device;
• activating, by the personal imaging device, sensors of the personal imaging device for collecting data regarding the user's interaction with the application on the mobile device;
• collecting, by the personal imaging device, data regarding the user's interaction with the application on the mobile device via the activated sensors and storing the data in a repository;
• detecting, by the personal imaging device, a visual end signal within the image displayed on the display of the mobile device;
• deactivating, by the personal imaging device, at least some of the sensors of the personal imaging device.
