A prototype of the sensor was created. In this version, the concept and the working principle of the 'adjustable spatial resolution' and the 'dynamic sensing range' were confirmed. Experiments showed that the resolution of the sensor can be increased and decreased quickly. At the same time, the sensing range was decreased and increased, respectively. This ability to quickly change the resolution add the versatility of the sensor; the sensor can detect the approach from further away and also able to localize the proximity in a short period of time (~12 Hz).
