Apparatus, method, and program product for hands-free controlling of projection based on viewing context

A method comprising:

• determining whether a predetermined condition is satisfied for projecting a video portion of audiovisual content, the video portion of the audiovisual content comprising guidance for performing one or more manual tasks by hand to a user in a selected viewing context in which the user does not use hand action to interact with an interface for controlling projection of the audiovisual content;
• determining one or more parameters of a field of view and an eye gaze direction of the user for the selected viewing context and sensing one or more characteristics of a target viewing surface within the field of view, wherein a hysteresis algorithm limits an update rate of the eye gaze direction estimation;
• and
• controlling at least one steerable projector, based on the parameters, to project the video portion of the audiovisual content on to the target viewing surface proximate to the manual task performance location such that the target view surface and the performance of the manual task by hand are concurrently viewable by the user, in response to determining that the predetermined condition is satisfied.

A computer program product comprising a computer readable non-transitory storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• determine whether a predetermined condition is satisfied for projecting a video portion of a content comprising guidance for performing one or more manual tasks by hand to a user in a selected viewing context in which the user does not use hand action to interact with an interface for controlling projection of the audiovisual content;
• determine one or more parameters of a field of view and an eye gaze direction of the user for the selected view context and one or more characteristics of a target viewing surface within the field of view and proximate to the manual task performance location, wherein a hysteresis algorithm limits an update rate of eye gaze estimation;
• and
• control at least one steerable projector, based on the parameters, to project the video portion of the content on to the target viewing surface proximate to the manual task performance location such that the target view surface and the performance of the manual task by hand are concurrently viewable by the user, in response to determining that the predetermined condition is satisfied.
