Haptic feedback generation

A computer readable storage device, comprising at least one executable instruction, which, in response to execution, causes a haptic feedback generation apparatus comprising a processor to perform operations, comprising:

• in response to determining that a first part of a user body is touching a target position of an object, sending a first mechanical wave to the object via a first medium comprising the first part;
• and
• sending, to the object via a second medium, a second mechanical wave that is used to form a haptic signal at the target position with the first mechanical wave, wherein the second medium comprises a second part, touching the object, of the user body.

The computer readable storage device according to 11, wherein the operations further comprise:

• acquiring information related to the target position.

The computer readable storage device according to 12, wherein the sending the second mechanical wave comprises sending the second mechanical wave according to the information related to the target position.

The computer readable storage device according to 12, wherein the haptic signal corresponds to the information related to the target position.

The computer readable storage device according to 11, wherein the haptic signal is formed through superposition of the first mechanical wave and the second mechanical wave.

A haptic feedback generation apparatus, characterized by comprising a processor and a memory, the memory storing executable instructions, the processor being connected to the memory via a communication bus, and when the haptic feedback generation apparatus operates, the processor executes the computer executable instructions stored in the memory, so that the haptic feedback generation apparatus executes operations, comprising:

• in response to a determination that a first part of a user body touches a target position of an object, sending a first mechanical wave to the object via a first medium comprising the first part;
• and
• sending, to the object via a second medium, a second mechanical wave that is used to form a haptic signal at the target position with the first mechanical wave, wherein the second medium comprises a second part, touching the object, of the user body.
