Insertable insoles of flexible air-injected elastomer material with one or both said insoles containing a lithium-battery power supply (27), a microprocessor with an internal timer, an analog / digital converter, and an actuator (28), connected by at least one wire (29) to a plurality of electronic sensors (12) wrapped around the toes of the foot. The actuator vibrates a plurality of raised nodes (20) on the insole(s) with the speed and intensity of vibrations in either direct or inverse response to the level of stress experienced, as measured by physiological signals such as galvanic skin response. A thin foam lining covers the top surface of the elastomer material and cushions the feet. In addition, a washable, stretchable nylon lining (30) separates the foam from the sole of the bare foot, but a small elastic hole (32) near the toes permits said wire and sensors to extend to the skin of the toes. Once either or both of the insoles are attached to the toes, the feet together with the insoles are inserted into a pair of socks or stockings.

The present invention provides a home control system using galvanic skin responses and heart rate information and a method thereof. Whether a user is awake is judged using a galvanic skin response sensor, and the extent of stress of a user is determined using the user's heart rate, thereby extracting a user's emotional state and sleeping state. Furthermore, based on these, various systems in the home network of a user are controlled according to the user's emotional state and sleeping state. In addition, those control results are stored in a database so as to create the optimum control conditions.

The invention discloses a taboo searching method for selection of galvanic skin response signal features, which includes the following steps: sequence backward algorithm is adopted to form N-1 rows and a two-dimensional table L of N lines, wherein the N represents total number of dimensions of selected features, each line represents one feature, each row is called one space, an nth space selects n features, and n is larger than or equal to 1 and less than or equal to N-1; a value of each element in the table is expressed by 0 or 1, 0 represents that the element is not selected when feature selection is performed, and 1 represents that the element is selected; the selected features in each space are solved by adopting taboo searching algorithm to obtain a table S formed by solution of each space; and a feature with the largest fitness function in each space serves as a final feature selection result. The taboo searching method for the selection of galvanic skin response signal features not only obtains effective features of skin electric signals with large contribution to emotion recognition, but also overcomes the shortcoming that a basic taboo searching algorithm is easy to get into local optimum.

A system for inducing a Pavlovian association of a scent with a state of less-than-moderate pain, to thereby minimize perceived pain, and to reduce the need for narcotic analgesics. The system includes at least a physiological sensor configured to detect at least one physiological parameter of the user. The physiological parameter of the user may include heart rate variability, blood pressure, galvanic skin response, movement, facial expression and the like.
