摘要

A haptic communication device includes an array of cutaneous actuators to generate haptic sensations corresponding to actuator signals received by the array. The haptic sensations include at least a first haptic sensation and a second haptic sensation. The array includes at least a first cutaneous actuator to begin generating the first haptic sensation at a first location on a body of a user at a first time. A second cutaneous actuator begins generating the second haptic sensation at a second location on the body of the user at a second time later than the first time.

說(shuō)明書

The correspondence between each haptic C-V pair and each spoken C-V pair may be selected based on articulation association, in a fashion similar to that described above for FIG. 11H.

FIG. 14E is a flowchart illustrating a method of converting input words into haptic output based on C-V pairs, according to an embodiment. The process described in the flowchart may be performed by the C-V pair haptic signal converter 1416, which in turn may be a component of a signal generator that may be part of a haptic device. Although a particular arrangement of steps is shown here, in other embodiments the process may be arranged differently.

Initially, the C-V pair haptic signal converter 1416 receives 1472 an input word which is a unit of a language that is written using C-V pairs, such as Hindi. The w C-V pair haptic signal converter 1416 converts 1474 the input word into its component C-V pairs.

The C-V pair haptic signal converter 1416 converts 1152 the C-V pairs into a sequence of actuator signals. This sequence is formed from a concatenation of sub-sequences of actuator signals. Each C-V pair in the language corresponds to one of these sub-sequences of actuator signals. Each of the actuator signals are mapped to a cutaneous actuator of a two dimensional array of cutaneous actuators placed on an interior surface of a harness shaped to wrap around a user's arm. The interior surface of the harness facing the user's arm when worn by the user.
