Abstract

The technical scheme of the invention is to provide a flexible tactile feedback device for exhibiting temperature and texture consistency presentation. The flexible tactile feedback device is composedof a touch module, a control module and a heat dissipation driving module. The touch module is in a bendable sheet shape and can provide temperature feedback and electrostatic vibration stimulation simulating texture touch. The tactile module comprises a flexible electrostatic vibration film, a flexible refrigeration sheet, a flexible radiator, heat-conducting silicone grease, radiating fin columns and a temperature sensor, the control module includes a temperature driver and an electrostatic vibration driver. The heat dissipation driving module comprises a water pump and a water pipe. The device has a bendable characteristic, allows a user to feel generated tactile feedback in a rubbing and sliding interaction mode, and can be attached to the surface of a curved-surface object to realizea tactile feedback function; joint feedback of temperature and texture information is achieved, a more vivid tactile feedback effect is achieved, and electrostatic vibration stimulation simulating texture is physical stimulation and cannot cause electric shock damage to a human body.

Description

technical field [0001] The invention provides a flexible tactile feedback device with consistent presentation of temperature and texture, relates to a bendable temperature and texture tactile feedback device, and belongs to the technical field of human-computer interaction. Background technique [0002] In virtual reality shopping, people have a strong demand for being able to touch the material of the product. For example, when buying clothes and other commodities in a virtual reality environment, people will follow the shopping habits of shopping malls and naturally touch the virtual clothes to feel the material of the clothes. [0003] In a real environment, when a person touches real clothing, temperature and texture are always coupled and inseparable. The above facts suggest that simulating temperature and texture at the same time seems to provide a more realistic material feel in virtual reality environments. A Chinese invention patent (application notification numbe...
