Method and apparatus to infer object and agent properties, activity capacities, behaviors, and intents from contact and pressure images
An apparatus for determining a non-apparent attribute of an object having a sensor portion with which the object makes contact and to which the object applies pressure. The apparatus has a computer in communication with the sensor portion that receives signals from the sensor portion corresponding to the contact and pressure applied to the sensor portion, and determines from the signals the non-apparent attribute. The apparatus has an output in communication with the computer that identifies the non-apparent attribute determined by the computer. A method for determining a non-apparent attribute of an object.
1. An apparatus for determining a non-apparent attribute of a person comprising:
a sensor portion of a plurality of sensor tiles forming a walkway with which the person makes contact and to which the person applies pressure a number of times a day; and
a computer in communication with the sensor portion that receives signals indicative of gait of the person moving on the walkway the number of times a day from the sensor portion corresponding to the contact and pressure applied to the sensor portion by the person, determines from the signals over time the non-apparent attribute based on center of pressure measurements of footsteps of the person.
2. A method for determining a non-apparent attribute of a person comprising the steps of:
making contact and applying pressure with a person to a sensor portion of a plurality of sensor tiles forming a walkway a number of times a day;
receiving signals by a computer in communication with the sensor portion from the sensor portion corresponding to the contact and pressure applied to the sensor portion indicative of gait of the person moving on the walkway the number of times a day;
determining by the computer from the signals the non-apparent attribute based on center of pressure measurements of footsteps of the person; and
identifying at an output in communication with the computer the non-apparent attribute determined by the computer.
3. A system to detect a plurality of localized pressure contact measurements with a surface comprising:
one or more stationary sensing units for collecting the pressure contact measurements; and
a computer in communication with the sensing units which makes one or more representations of an object's surface pressure contact interaction and extracts patterns and features of the representations to infer object movement behavior and intent utilizing a program stored in a memory of the computer having multiple processing levels that provide progressively higher level representations of the object from the pressure contact measurements.
