Abstract: One example provides a computing device comprising instructions executable to receive information regarding one or more entities in the scene, to receive eye tracking a plurality of eye tracking samples, each eye tracking sample corresponding to a gaze direction of a user and, based at least on the eye tracking samples, determine a time-dependent attention value for each entity of the one or more entities at different locations in a use environment, the time-dependent attention value determined using a leaky integrator. The instructions are further executable to receive a user input indicating an intent to perform a location-dependent action, associate the user input to with a selected entity based at least upon the time-dependent attention value for each entity, and perform the location-dependent action based at least upon a location of the selected entity.

Abstract: A computer-implemented method for determining focus of a user is provided. User input is received. An intention image of a scene including a plurality of interactive objects is generated. The intention image includes pixels encoded with intention values determined based on the user input. An intention value indicates a likelihood that the user intends to focus on the pixel. An intention score is determined for each interactive object based on the intention values of pixels that correspond to the interactive object. An interactive object of the plurality of interactive objects is determined to be a focused object that has the user's focus based on the intention scores of the plurality of interactive objects.
