Thermal tactile representation device of virtual experiment platform

Abstract

The invention provides a thermal tactile representation device of a virtual experiment platform. The system comprises a heating module, a positioning module and a control module. The positioning module comprises a guide rail device, a first ball screw and a second ball screw. The guide rail device comprises a first guide rail, a second guide rail and a third guide rail. The first guide rail is provided with a first stepping motor used for driving the first ball screw to rotate, and the third guide rail is provided with a second stepping motor used for driving the second ball screw to rotate. The heating module comprises a PTC heating body, a cooling fan and a movable sliding block which are sequentially arranged from top to bottom, and a second ball screw penetrates through the movable sliding block. The control module can control the first stepping motor and the second stepping motor to enable the heating module to move on the XY plane, and meanwhile control the PTC heating body and the cooling fan to work. According to the invention, the PTC heating body emits hot air to reproduce the stimulation of heat generated by a heat emitting object in an experiment on the skin of a humanbody under a real condition, and the effect of reproducing thermal tactile sensation is achieved through non-contact thermal perception.

Description

technical field [0001] The invention belongs to the field of virtual reality tactile reproduction, and in particular relates to a thermal tactile reproduction device for a virtual experiment platform. Background technique [0002] Virtual reality technology is a technology that can reproduce vision, hearing, touch, and smell. The current virtual reality technology mainly virtualizes reality visually. Among them, such as pain, itching, slippery, temperature, etc., temperature perception in temperature sense is an important basis for human skin to distinguish different objects, and it is an indispensable reproduction link of virtual reality technology. [0003] At present, in the field of virtual reality, the existing thermal tactile reproduction products mainly exist in the form of data gloves. By adding small resistors to each finger cover, and then passing current through the resistors to generate heat, the skin of the fingers can feel the heat. Stimulate. For hot and col...

Problems solved by technology

However, these existing methods bring some problems to the immersion of virtual reality technology, because in the virtual environment, a lot of heat is generated through non-contact, and what is needed is to spread heat through the air medium

In the above-mentioned thermal tactile reproduction method, water is used for heating and cooling. Due to the influence of the physical characteristics of water, water pipes, valves and other objects are needed to transmit heat, which increases the volume and cost of the equipment; Tactile reproduction, although it can provide heat conveniently, but the heat is limited, and the non-contact heat cannot meet the needs of virtual experiments
