Description

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY

The present application claims priority from Indian Patent Application no. 201921041905 filed on the 16 Oct. 2019, the details of which are incorporated herein by a reference.

TECHNICAL FIELD

The present subject matter described herein, in general, relates to a haptic feedback capturing device and a method thereof.

BACKGROUND

The subject matter discussed in the background section should not be assumed to be prior art merely because of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.

Virtual reality enables in providing a possibility to interact with a virtual environment. The virtual reality consists of software and hardware technologies which interact with the user to immerse him/her in the virtual environment. Objects in the virtual environment are perceived through technology acting on human senses. These technologies are constituted of visualization devices, haptic feedback, sound feedback, tactile and force feedback, as well as motion platform, for example.

In the field of Virtual Reality or Augmented reality, haptic feedback or haptics is the deployment of vibration or pressure to engage your sense of touch when using technology. The users can see virtual objects and may even feel them when they bump up against them. Currently, the wearable surfaces or systems such as gloves, or controllers are used in order to allow the wearer to manipulate a virtual hand, perform an action associated with virtual objects in the virtual reality and feel its shape.

In an air-bubble based haptic feedback system, each VR glove comprises a flat little air pocket encased in a thin silicone skin. By varying the air pressure in the pocket, an air bubble is formed as the shape of the silicone is changed. Varying the signal changes the height of the bubble, and the signals can be turned ON and OFF instantly reflecting corresponding changes in the air pressure in the air bubble. It should be noted herein that little air bubble is the key to feeling the sense of touch. The user feels the touch based upon the change in the height of the air bubble.

In the vibration based haptic feedback system, each VR glove comprises of a resonant actuator to detect virtual objects and provide haptic feedback to the glove. When the virtual hand touches the virtual objects, the glove presents vibration stimuli corresponding to the contact site thereby providing a haptic feedback.

Further, few of the existing VR/AR technologies use vibrating motors for capturing the haptic feedback. More specifically, the vibrating motors are placed in handheld remotes and videogame controllers. In video games for example, when there are events in the games being played (for example, any virtual explosions, bumping into virtual objects, touching virtual objects etc.), vibrations are sent to indicate these events. However, the existing system has limitation of body part which can interface with the virtual world. Further, the existing system are not compatible with other wearable or dynamic surfaces.

A haptic feedback capturing device, comprising: a plurality of electromagnets and a plurality of permanent magnets arranged in form of a matrix, wherein each cell in the matrix comprises one or more electromagnets, of the plurality of electromagnets, and one or more permanent magnet(s) of the plurality of permanent magnets, wherein the matrix is communicatively coupled with a communication device, wherein the at least one coil associated to each electromagnet corresponding to each cell in the matrix is configured to be activated based upon receipt of an activation signal from the communication device, and wherein the at least one coil activated creates a repulsive force between the at least one electromagnet and the permanent magnet belonging to the cell corresponding to at least one coil activated, and wherein the permanent magnet is repelled from the at least one activated coil and touches the skin of user in order to generate sensation of touch thereby capturing the haptic feedback.

12. The haptic feedback capturing device as claimed in claim 11, wherein a separation layer is present between the matrix of the plurality of electromagnets and the plurality of permanent magnets, and skin of the user.

13. The haptic feedback capturing device as claimed in claim 11, wherein coil associated to each electromagnet is placed around or at a close distance to each permanent magnet corresponding to respective cell in the matrix closer to the user's skin.

14. The haptic feedback capturing device as claimed in claim 11, wherein the communication device is a Virtual reality (VR) device or an Augmented reality (AR) device.

15. The haptic feedback capturing device as claimed in claim 11, wherein the communication device is a display device associated with braille user.

16. A method for capturing haptic feedback, the method comprising: configuring, on a haptic feedback capturing device, a matrix of a plurality of electromagnets and a plurality of permanent magnets, wherein each cell in the matrix comprises one or more electromagnets, of the plurality of electromagnets, and one or more permanent magnet(s) of the plurality of permanent magnets, wherein the matrix is communicatively coupled with a communication device;receiving, by the haptic feedback capturing device, an activation signal from the communication device; andactivating, by the haptic feedback capturing device, at least one coil associated to each electromagnet corresponding to each cell in the matrix based upon the activation signal, wherein the at least one coil activated creates a repulsive force between at least one electromagnet and the permanent magnet belonging to the cell corresponding to the at least one coil activated, and wherein the permanent magnet is repelled from the at least one activated coil and touches the skin of user in order to generate sensation of touch thereby capturing the haptic feedback.
