Description

Technical Field

[0001] The invention relates to the field of consumer electronic product perception, and in particular to a method for changing a person's perception of the surface temperature of an electronic device through vibration. Background Art

[0002] In handheld and wearable electronic products such as mobile phones, the phenomenon of device heating due to computing and batteries is particularly obvious. Higher surface temperatures affect the user experience of holding or wearing the device for a long time, and may even make the user feel that their skin is being toasted. Therefore, it is crucial to control device heating through appropriate methods without affecting the user's safety and physiological health. However, it takes a certain amount of time to reduce and regulate the temperature, and it may affect the performance of the device in specific scenarios. Therefore, under the condition that it is impossible to directly reduce the temperature to the user's comfort zone in the short term, it is of great value to reduce the user's psychological feelings about the heating device through reasonable methods.

[0003] In relevant human factors research, it was found that one tactile stimulus may interfere with or reduce the perception of another tactile stimulus. This phenomenon is called tactile masking. This phenomenon is affected by many factors, including temporal proximity, spatial proximity, differences in sensory intensity, and the allocation of attention. Strong tactile signals may mask a person's perception of other weaker tactile signals, and concentration of attention may also cause other simultaneous tactile stimuli to be ignored. Long-term exposure to the same tactile stimulus may also cause a decrease in sensitivity, which is a result of adaptive changes. The MIT research team found that simultaneous vibration stimulation can affect the user's ability to recognize thermal tactile information. Studies have shown that different vibration waveforms have different degrees of interference with thermal perception.

[0004] The phenomenon of thermal transfer refers to the transfer of thermal sensation to nearby locations through the interaction of heat and other tactile sensations, which is caused by the redistribution of thermal sensation. When thermal stimulation and vibration stimulation are presented at different locations A and B respectively, the thermal sensation will appear at the location B of the tactile stimulation. This means that thermal stimulation can be transferred through the thermal illusion induced by vibration at different locations, so that the user feels an illusory thermal sensation at the tactile location. The thermal sensation at the thermal stimulation location A will be weakened or even completely masked.

[0005] This study proposes to use tactile masking and thermal transfer phenomena to reduce the user's subjective perception of heat, thereby optimizing the user's psychological experience of the surface temperature of electronic consumer products and wearable devices. This method can improve the user's comfort and long-term use experience of holding or wearing the device by interfering with the user's thermal experience and cooperating with other software and hardware temperature control technologies. Summary of the invention

[0006] 1. Technical issues to be resolved The present invention focuses on the phenomenon of heat shielding and heat transfer, and adds vibration stimulation to interfere with the user's perception of heat. Combining the device's thermal management system and vibration feedback, an intelligent temperature control system is created, which can automatically activate vibration feedback when the device temperature rises, and provide vibrations of specific frequency and intensity on the heating surface or different hand-held and worn parts. Vibration reduces the user's sensitivity to the thermal experience of the device contact surface. Users can also adjust the vibration intensity according to their personal preferences to adapt to different thermal perception thresholds and comfort levels.

[0007] (II) Technical solution A method for changing a person's perception of the surface temperature of an electronic device through vibration comprises the following steps: S101: The internal system of the electronic device monitors its own temperature. When the temperature reaches a certain threshold, the system starts temperature control. S102: One or more vibrator units of the product are activated, and a vibration of a specific frequency (e.g., 60 Hz) and intensity is output through a preset program, and the device generates surface vibration stimulation; S103: The user holds or wears the device, and feels the vibration stimulation while touching the heat on the surface of the device; S104: The user's thermal perception of the current device surface is disturbed by the vibration occurring simultaneously, thereby reducing the user's subjective sensitivity to the heating of the device; This technology can also coordinate temperature control across devices, using the phenomenon of thermal transfer to transfer heat to other parts of the body.

[0008] Preferably, vibration is achieved through collaboration between the mobile phone and the watch, and between the watch and the head-mounted display.

[0009] This technical method can also allow users to set the mode and parameters of vibration feedback according to their preferences.

[0010] Beneficial effects of the present invention: This solution is essentially a "pseudo cooling" method. Compared with other "real cooling" equipment temperature control methods such as frequency reduction and heat dissipation, its advantages are: The actual heating problem of the device should not be reduced at the expense of the actual computing performance, image quality, frame rate, etc. of the device; Compared with physical cooling methods that take some time for the surface temperature to improve and allow users to feel the device cooling down, this method has a short effect and is quick to take effect through the physiological and psychological characteristics of shielding and transfer. It can also be combined with other "real cooling" methods to quickly improve user experience in the early stages of temperature control. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is described in further detail below by way of examples. Example

[0021] A method for changing a person's perception of the surface temperature of an electronic device through vibration comprises the following steps: S101: The internal system of the electronic device monitors its own temperature. When the temperature reaches a certain threshold, the system starts temperature control. S102: One or more vibrator units of the product are activated, and a vibration of a specific frequency (e.g., 60 Hz) and intensity is output through a preset program, and the device generates surface vibration stimulation; S103: The user holds or wears the device, and feels the vibration stimulation while touching the heat on the surface of the device; S104: The user's thermal perception of the current device surface is disturbed by the vibration occurring simultaneously, thereby reducing the user's subjective sensitivity to the heating of the device; This technology can also coordinate temperature control across devices, using the phenomenon of thermal transfer to transfer heat to other parts of the body.

[0022] This technology can achieve cooperative vibration between mobile phone and watch, or between watch and head-mounted display.

[0023] This technical method can also allow users to set the mode and parameters of vibration feedback according to their preferences. Example

[0024] like Figure 1As shown in the figure, user scenario 1: When the user is playing mobile games, the temperature of the phone begins to rise rapidly, and soon reaches the temperature threshold that is uncomfortable for the user to hold for a long time. The system detects that the temperature is too high and turns on the temperature control function. Through this method, the vibration feedback of the mobile phone is activated, and the vibration stimulation immediately masks the user's sensitivity to heat, making the user feel that the device is not overheated and no longer distracted by the surface temperature of the device. At the same time, the vibration feedback gives the user a signal that the phone will start to control the temperature by limiting the game frequency and frame rate. In order to reduce the interference of vibration on the game and individual differences among users, users can manually set the parameters of the vibration feedback. Example

[0025] like Figure 2 As shown, user scenario 2: the user wears a watch while using a mobile phone. The temperature of the mobile phone rises rapidly due to the application, reaching a threshold that is difficult for the user to accept. At this time, the mobile phone system detects that the temperature is too high and turns on the temperature control function. Through this method, while the mobile phone controls its own temperature, it can also activate the vibrator of the watch connected to it, generating specific vibration stimulation on the wrist where the watch is worn. Through the phenomenon of thermal transfer, the heat sensation of the palm and fingers is partially transferred to the wrist of the watch, thereby dispersing the user's thermal sensation of the mobile phone being held. Example

[0026] like Figure 3 As shown in the figure, user usage scenario 3: When the XR headset is used for a long time or runs high-performance content, a large amount of heat may be generated, causing discomfort to the user's face. Through this method, the intelligent temperature control system can activate the vibration feedback of the built-in device or other on-body devices when the temperature of the headset device rises, and reduce the user's thermal perception of the headset device through one or more body contact points, thereby extending the user's wearing time.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
