In embodiments, the processor circuit 232 may generate the haptic symbol set, where a distance between each haptic symbol of the haptic symbol set and each other haptic symbol of the haptic symbol set is greater than a threshold. The distance described herein may indicate, for example, spatial distances between the actuators operated by the haptic illusions signal 202, a timing difference between vibrations of the same or different actuators. The benefits and advantages of this method are that the haptic symbols of the resulting haptic symbol set are distinguishable from each other. The receiving user can thus more easily comprehend the haptic communication.
In one embodiment, the distance between each haptic symbol of the haptic symbol set and each other haptic symbol of the haptic symbol set may be determined by one or more of a Minkowski distance, a Mahalanobis distance, a Matsushita distance, a chi-squared distance, a Hamming distance, a cosine similarity, a dot product, and a Grassmann distance.
The haptic communication system 200 may further generate an implicit learning program based on the haptic symbols and the received speech signals, where the implicit learning program is immersive, non-intentional, age-independent, IQ-independent, and subconscious. The benefits and advantages of this approach are that the receiving user may more easily learn the haptic symbol set and the particular language of haptic communication that it represents.
