Directional impression analysis using deep learning

A system including one or more processors and a memory, the memory comprising instructions that, when executed, cause the one or more processors to perform operations comprising:

• using sequences of frames produced by sensors to identify (i) locations of identified subjects in an area of real space and (ii) interest, by the identified subjects, in identified items positioned at locations in the area of real space;
• storing the identified items for which interest was identified as entries in a database, the entries including an item identifier and a location of the items in the area of real space;
• and
• generating a heat map of at least a portion of the area of real space, wherein the heat map identifies locations, in the area of real space, of identified items for which the interest by the identified subjects exceeds a threshold.

A non-transitory computer readable storage medium impressed with computer program instructions to detect gaze direction of subjects in an area of real space, the instructions, when executed on a processor, implement a method comprising:

• using sequences of frames produced by sensors to identify (i) locations of identified subjects in an area of real space and (ii) interest, by the identified subjects, in identified items positioned at locations in the area of real space over time;
• storing the identified items for which interest was identified as entries in a database, the entries including an item identifier and a location of the items in the area of real space;
• and
• generating a heat map of at least a portion of the area of real space, wherein the heat map identifies locations, in the area of real space, of identified items for which the interest by the identified subjects exceeds a threshold.
