Abstract
A tactile perception system is provided. The tactile perception system includes a storage unit storing tactile data and feature information corresponding to the tactile data, a sensing unit sensing surface characteristics of an object to generate a sensing signal, an extraction unit extracting sensing information from the sensing signal generated by the sensing unit, and a matching unit extracting a piece of feature information, which is matched with the sensing information, from the feature information stored in the storage unit and extracting a piece of tactile data, which corresponds to the piece of feature information, from the tactile data stored in the storage unit.
Claims15
A tactile perception system comprising:
- a storage unit storing tactile data and feature information corresponding to the tactile data;
- a sensing unit sensing surface characteristics of an object to generate a sensing signal;
- an extraction unit extracting sensing information from the sensing signal generated by the sensing unit;
- and
- a matching unit extracting a piece of feature information, which is matched with the sensing information, from the feature information stored in the storage unit and extracting a piece of tactile data, which corresponds to the piece of feature information, from the tactile data stored in the storage unit.
A method of building a database of a tactile perception system, the method comprising:
- generating a sensing signal by sensing surface characteristics of an object;
- extracting sensing information corresponding to the surface characteristics of the object from the sensing signal;
- and
- matching and storing the surface characteristics of the object and the sensing information.
A tactile perception system comprising:
- a sensing unit sensing surface characteristics of a target object and a comparative object to generate a target sensing signal and a comparative sensing signal, respectively;
- an extraction unit extracting target sensing information from the target sensing signal and the comparative sensing signal generated by the sensing unit;
- and
- a storage unit matching the target sensing information with tactile data of the target object and storing the target sensing information and the tactile data of the target object,
- wherein the extraction unit frequency-converts the target sensing signal and the comparative sensing signal, and
- wherein the extraction unit compares the frequency-converted target sensing signal with the frequency-converted comparative sensing signal to define at least some of frequency values and corresponding peak values, at which differences between peak values exist, as the target sensing information.
