Abstract

New activity recognition, recording, analysis and control techniques, systems and sensors are provided. In some aspects of the invention, multiple sensory tags with unique identification and data transfer attributes, create positional, movement, orientation and acceleration data and supply it to a control system. The tags may be placed at location(s) on the user'"'"'s body, clothing, personal effects, exercise equipment and other activity-relevant locations, to enhance activity recognition and mapping. For example, a specialized PDA may comprise part of the control system, and may provide, reflect and/or receive modified data signals to and from such tags.

In other aspects, a system defines a personal activity space, samples data preferentially from that space, and performs a simplified form of object-recognition to determine, record and analyze personal activities.

A GUI interface within the control system may also aid in recognizing and recording activity patterns, in addition to tags.

Claims

1. A system for determining an activity of a user comprising:

a hardware device comprising;

at least one infrared imaging sensor configured to receive infrared radiation signals emanating from an object located within a predefined, three-dimensional personal activity space and not within a space outside of said personal activity space,

wherein said at least one sensor is configured to detect object-defining thermal differentials in said 3-dimensional personal activity space;

a memory in communication with the device, the memory adapted to store;

object information relating to a plurality of potential object types with which the user may interact; and

activity information relating to a plurality of potential activities the user may undertake with one or more of the potential object types;

a processor in communication with the device and the memory, the processor configured to;

determine a first position of the object in three-dimensional space at a first time, based on at least some of the radiation;

determine a three-dimensional shape of the object, based on at least some of the radiation;

determine an object type of the detected object from the plurality of potential object types stored in the memory, based on the determined shape of the object; and

determine the activity of the user from the plurality of potential activities stored in the memory, based on the object type and the first position of the object.

2. A system according to claim 1:

wherein the processor is further configured to determine a first temperature of the object; and

wherein said determining the object type is further based on the first temperature of the object.

3. A system according to claim 2:

wherein the processor is further configured to determine a first temperature of the user; and

wherein said determining the activity of the user is further based on the first temperature of the user.

4. A system according to claim 1, wherein the processor is further configured to determine a second position of the object, at a second time.

5. A system according to claim 4:

wherein the processor is further configured to determine an object movement of the object, based on the first position and the second position of the object; and

wherein said determining the activity of the user is further based on the object movement.

6. A system according to claim 5:

wherein the processor is further configured to;

determine a second size of the object; and

determine a change in size of the object, based on the first size and the second size; and

wherein said determining the activity of the user is further based on the change in size of the object.

7. A system according to claim 6:

wherein the processor is further configured to;

determine a second temperature of the user; and

determine a change in user temperature, based on the first and second user temperatures; and

wherein said determining the activity of the user is further based on the change in user temperature.

8. A system according to claim 7:

wherein the object comprises a food;

wherein the user activity comprises eating the food; and

wherein the processor determines a number of calories consumed by the user during eating of the food, based on one or more of;

the movement of the object, the change in size of the object and the change in user temperature.

9. A system according to claim 1, wherein the stored object information relating to a plurality of potential object types with which the user may interact comprises one or more of:

object size, object shape, object temperature, object temperature loss, object temperature loss rate and object movement.

10. The system of claim 1, wherein the processor is further configured to analyze information related to the radiation differently from information related to other radiation that emanates from outside of the predefined personal activity space.

11. The system of claim 10, wherein the processor is further configured to treat said other radiation that emanates from outside of the predefined personal activity space as an environmental condition indicator.

12. The system of claim 1, wherein the predefined personal activity space comprises a radius of between 4 and 70 inches surrounding the device.

13. The system of claim 12, wherein the predefined personal activity space is automatically determined by the system based on a time of day.
