Outline of Final Research Achievements

We tried to detect a decrease in concentration of human who is working on the desk or doing something not to make an alarm but to capture opportunity to interrupt without giving nuisance. Our attention is focused on the indices derived from electrocardiogram (ECG) and respiration, which are more likely to be measured non-intrusively. For ECG we used the capacity coupled electrodes attached on the back of the chair. Respiration was measured detecting the variations of the back pressure using air bags. Executing the experiments simulating two scenes; working with PC and watching TV in the living room, we confirmed that the selected measures change depending on the degree of concentration. The method was implemented that realize the robot’s approaches at the timing of the human’s degraded concentration detected using support vector machine. Further study is necessary to validate the effectiveness of robot’s approach depending on human states.
