Abstract
Robot-assisted rehabilitation therapies get to improve patient’s motivation and exercise intensity. For this purpose, one of the methods with the most promising results is the use of difficulty-adapting algorithms. This algorithms are usually based in game performance parameters. However, the consideration of the patient’s emotional state could improve the decision making in this kind of strategies. One of the most used physiological signals for estimating the state of the patient is GSR. GSR sensors use direct current to measure skin conductance. In this article, the use of alternating current to measure skin conductance is proposed. This kind of current can provide more information because it can penetrate further in the user’s skin. In this study, a GSR sensor capable of measuring both direct and alternating current was designed and evaluated in order to estimate the patient’s state during a rehabilitation game with several difficulty levels.
