Temperature reproducing method and device capable of sensing continuously

Abstract

The invention discloses a temperature reproducing method and a temperature reproducing device capable of sensing continuously. The method comprises the following steps of: a, changing the temperature from an initial temperature to a first temperature value in a heat sensation perception temperature interval at a first speed, and keeping the first temperature value for a while from a moment when the temperature reaches the first temperature value; b, stopping heating; c, when the temperature drops to a second temperature value in the heat sensation perception temperature interval, controlling the temperature to reach the first temperature value once again; and d, repeating steps b to c. Due to the adoption of the temperature reproducing method and the temperature reproducing device, a human body can keep sensitivity to cold sensation and heat sensation for a long time, the continuous temperature sensation reproducing time of a temperature sensation reproducing and expressing device is prolonged, the energy consumption of temperature sensation reproducing and expressing device is lowered, and the working time of the temperature sensation reproducing and expressing device is prolonged on the premise of limited energy resource; and temperature sensation expression of different information can be realized by controlling the intensities of the cold sensation and the heat sensation and alternative reproducing of the cold sensation and the heat sensation.

Description

Technical field [0001] The invention relates to tactile reproduction technology, in particular to a temperature reproduction method and a temperature reproduction and expression device, which are suitable for continuous temperature perception. Background technique [0002] The human body receives different stimuli through the skin and its accessory receptors, and produces various types of sensations. There are "cold spots" and "hot spots" on the skin, and there are cold receptors and heat receptors respectively, which are used to feel the cold and heat stimuli on the skin. Stimulating these points can cause heat and cold sensations, collectively called temperature sensation. The temperature perception of the skin is affected by factors such as the basal temperature of the skin, the speed of temperature change, and the extent of the skin being stimulated. When the human skin temperature is 32~34℃, there is neither cold nor hot feeling, which is the middle range of skin temperatu...

Problems solved by technology

In addition, the energy consumption of the device is high when using the traditional method to reproduce the temperature of heat and cold

[0005] The continuous temperature perception technology of the existing technology requires the device to work continuously. For some temperature perception reproduction and expression devices that cannot be water-cooled or cannot be equipped with bulky radiators, the problem of heat dissipation is particularly prominent.

In addition, the energy consumption of the device is high when using the traditional method to reproduce the temperature of heat and cold
