Tracking of item of interest using wearable heads up display

A wearable heads-up display (WHUD) comprising:

• a camera to capture scenes in a line of sight of a user wearing the WHUD;
• a light engine to generate a display light;
• a display optic to receive the display light from the light engine and to direct the display light towards an eye of the user of the WHUD to form an image viewable by the user;
• and
• a controller in communication with the camera and the light engine, the controller to:
• obtain attribute data corresponding to an attribute of an item of interest;
• detect the item of interest based on the attribute data by
• obtaining environmental data captured by the WHUD for an environment surrounding the WHUD;
• and
• responsive to the environmental data including the attribute data,
• determining the item of interest has been detected;
• obtain, in response detecting the item of interest, location data indicative of a location of the item of interest;
• store the location data in association with a context of detection of the item of interest, wherein the context of detection includes an image indicative of a position of the item of interest relative to another item in the environment;
• and
• in response to a user-generated query associated with a location of the item of interest, output a location indication for the item of interest based on the location data.

A method comprising:

• obtaining attribute data corresponding to an attribute of an item of interest;
• detecting, using a wearable heads-up display (WHUD), the item of interest based on the attribute data and by:
• obtaining environmental data captured by the WHUD for an environment surrounding the WHUD;
• and
• responsive to the environmental data including the attribute data, determining the item of interest has been detected;
• obtaining, in response to the detection, location data indicative of a location of the item of interest;
• storing the location data in association with a context of detection of the item of interest, wherein the context of detection includes at least one of a time of detecting of the item of interest or an image indicative of a position of the item of interest relative to another item in the environment;
• in response to a user-generated query associated with a location of the item of interest, outputting a location indication for the item of interest based on the location data;
• and
• responsive to outputting the location indication, further outputting at least one of the time of detecting of the item or the image indicative of a position of the item of interest relative to the other item in the environment.
