User profile generating system and method
A user profile generating system for generating a user profile for use with a processing device operable to display content includes: a head motion tracking unit operable to identify head motion of the user, an eye motion tracking unit operable to identify eye motion of the user, and a profile generating unit operable to generate a user profile comprising head tracking and eye tracking information for the user, where the generated user profile is used to modify interactions between the user and a processing device.
1. A user profile generating system for generating a user profile for use with a processing device operable to display content, the system comprising:
a head motion tracking unit operable to identify head motion of the user;
an eye motion tracking unit operable to identify eye motion of the user;
a profile generating unit operable to generate a user profile comprising head motion and eye motion information for the user;
a display content identification unit operable to identify a particular one or more displayed elements among a plurality of displayed elements within displayed content;
an identification interaction unit operable to identify an interaction with the particular one or more of the plurality of displayed elements within the displayed content; and
an interaction characterisation unit operable to characterize the identified interaction in dependence upon the head motion and eye motion information in the user profile, wherein:
the user profile identifies user preferences for eye motion and head motion, and
the user profile identifies proportions of head motion and eye motion used by a user in performing one or more viewing transitions between displayed content elements.
2. A system according to claim 1 , comprising:
a calibration unit operable to perform a calibration process for an application or device associated with the processing device; and
a calibration modification unit operable to modify the calibration process for a user in dependence upon information in their generated user profile.
3. A system according to claim 2 , wherein the calibration modification unit is operable to modify the location of viewing targets within content displayed during the calibration process.
4. A system according to claim 3 , wherein one or more of the displayed elements are moved closer to the centre of the displayed content.
5. A system according to claim 1 , wherein the generated user profile is used to modify interactions between the user and a processing device.
6. A system according to claim 1 , wherein the interaction characterisation unit is operable to identify user interest in displayed elements based upon the characterisation.
7. A system according to claim 1 , wherein the interaction characterisation unit is operable to identify a level of user tiredness based upon the characterisation.
8. A system according to claim 1 , wherein interactions are one or more of the list comprising viewing content, gaze-based inputs, gesture inputs, spoken inputs, and control device inputs.
9. A system according to claim 1 , wherein the head motion tracking unit is operable to identify head motion in dependence upon motion sensor data and/or camera data.
10. A system according to claim 1 , wherein the user profile identifies a user as belonging to one or more categories in dependence upon their preferences for eye motion and head motion.
11. A user profile generating method for generating a user profile for use with a processing device operable to display content, the method comprising identifying head motion of the user;
identifying eye motion of the user;
generating a user profile comprising head motion and eye motion information for the user;
identifying a particular one or more displayed elements among a plurality of displayed elements within displayed content;
identifying an interaction with the particular one or more of the plurality of displayed elements within the displayed content; and
characterizing the identified interaction in dependence upon the head motion and eye motion information in the user profile, wherein:
the user profile identifies user preferences for eye motion and head motion, and
the user profile identifies proportions of head motion and eye motion used by a user in performing one or more viewing transitions between displayed content elements.
12. A non-transitory machine-readable storage medium which stores computer software, which when executed by a computer system, causes the computer system to perform user profile generating method for generating a user profile for use with a processing device operable to display content, by carrying out actions, comprising:
identifying head motion of the user;
identifying eye motion of the user;
generating a user profile comprising head motion and eye motion information for the user;
identifying a particular one or more displayed elements among a plurality of displayed elements within displayed content;
identifying an interaction with the particular one or more of the plurality of displayed elements within the displayed content; and
characterizing the identified interaction in dependence upon the head motion and eye motion information in the user profile, wherein:
the user profile identifies user preferences for eye motion and head motion, and
the user profile identifies proportions of head motion and eye motion used by a user in performing one or more viewing transitions between displayed content elements.
