A computer mouse may be used as a pointing device. The computer mouse may receive inputs in the form of detected clicks and motion from a user and allow a user to interact with a computing device.
People today are spending increasing amount of time on personal computers For some users, especially with poor circulation, this prolonged usage can cause discomfort by their hands getting cold. Another subset of users has an issue with their hands getting too hot, especially when playing games. A thermoelectric cooling (TEC) device integrated into the mouse may generate heat or cooling. Utilizing a TEC may a create a situation that may leave a user's hand too hot or too cold. Disclosed herein is a thermoelectric feedback mouse system that utilizes a plurality of temperature sensors with a TEC to create a temperature gradient, to which a machine learning model is trained to a specific user.
In one example, a plurality of temperature sensors, a TEC, and a processor, receive temperature values from a proximity near a user's fingers and palm, receive a user feedback, activate the TEC device, and input the temperature readings and the feedback into a machine learning model.
A computing device 102 may house the processor 104 in one example. The computing device 102 may include but is not limited to a personal computer, laptop computer, cloud enabled gaming system, or a video game console. In another implementation the processor 104 may be housed in the mouse or pointing device. The processor 104 may be a specific purpose processor or tensor processing unit designed to receive the temperature sensor input, activate the thermoelectric device, and implement a machine learning model on the mouse. The computing device 102 may include a communication channel that may transmit mouse inputs to the computing device 102 to be processed by the processor 104. The computing device 102 may provide power to operate the plurality of sensors and the thermoelectric cooling device 110. The communication channel may be implemented as a universal serial bus (USB) cable. In another implementation, the communication channel may be wireless utilizing a radio frequency receiver interfacing with the computing device via USB. The mouse or pointing device may include a radio transceiver and independent power supply to operate the plurality of temperature sensors and the thermoelectric cooling device 110. The mouse or pointing device may include a housing that supports the physical components including the plurality of temperature sensors, a thermoelectric cooling device, as well as the mouse internals (not shown).
A plurality of temperature sensors including a first temperature sensor 106 and a second temperature sensor 108. The plurality of temperature sensors may be implemented as but not limited to negative temperature coefficient thermistors, resistance temperature detector, thermocouple, or semiconductor-based temperature-sensitive voltage circuits. In another implementation, additional sensors may be utilized to provide additional temperature inputs. An additional sensor may include an ambient temperature sensor. The ambient temperature sensor may include a connected smart thermostat. Input from the ambient temperature sensor may be received from additional systems (no shown) that may interface with the computing device 102 and the processor 104.
The processor 104 may be the central processing unit (CPU) of the host computing device 102. In another example, the processor 104 may be virtualized and distributed across more than one general purpose processors. In another implementation, the processor 104 may be a graphics processing unit (GPU) utilized to execute parallel machine learning models. In another implementation, the processor 104 may be a dedicated application-specific integrated circuit (ASIC) dedicated to machine learning activities such as a tensor processing unit (TPU).
In another implementation, the thermoelectric feedback mouse may include a biometric sensor. The biometric sensor may include a fingerprint sensor integrated into the surface of the mouse. The fingerprint sensor may be aligned such that a user's fingertip interfaces with the fingerprint sensor. The fingerprint sensor may correlate a first input and second input from the plurality of temperatures sensors to a specific user. Correlating the sensor input may be utilized to train separate machine learning models based on specific users. For example, a family may share a computer with an attached thermoelectric feedback mouse. The mother of the family may use the mouse and may define comfort as one temperature range. The father of the family may define his comfort as a different temperature range. Utilizing the fingerprint scanner, and a scanned finger print, the thermoelectric feedback mouse may correlate respective temperature inputs, and feedbacks to that specific user.
At 202, the processor 104 receives a first input from a first temperature sensor of a plurality of temperature sensors wherein the first temperature sensor is positioned in proximity to a user's finger. The first input may correspond to a temperature reading from a user's finger. In another implementation, the first temperature sensor may correspond to a logical grouping of two or more sensors located in proximity to a user's fingers on the mouse or pointing device. Each of the two or more sensors may provide a temperature reading to be included in the first input. The first temperature sensor transmits the first input to the processor 104 over a communication channel which may be wired or wireless.
At 204, the processor 104 receives a second input from a second temperature sensor from the plurality of temperature sensors wherein the first temperature sensor is positioned in proximity to a user's palm. The second input may correspond to a temperature reading from a user's palm. In another implementation, the second temperature sensor may correspond to a logical grouping of two or more sensors located in proximity to a user's palm on the mouse or pointing device. Each of the two or more sensors may provide a temperature reading to be included in the second input. The second temperature sensor transmits the second input to the processor 104 over a communication channel which may be wired or wireless.
At 206, the processor 104 receives a third input from an ambient temperature sensor from the plurality of temperature sensors. As discussed previously, the ambient temperature sensor may be implemented as a connected smart thermostat. The processor 104 may access the ambient temperature sensor through an application programming interface (API) and collect information corresponding to the ambient temperature of the physical location. Utilizing an ambient temperature sensor that is not integrated with the mouse system may provide more accurate ambient temperatures, as the thermoelectric cooling device may generate dissipate heat when cooling the user's hand. The heat dissipation may interfere with any local measurements of ambient temperature.
At 208, the processor 104 activates a thermoelectric device responsive to a machine learning model output wherein the first input, second input, and third input comprise a corresponding machine learning model input. The first, second, and third inputs may be utilized inputs into a classification model. The machine learning model may be a linear regression, multi-class classification or a support vector machine. The inputs result in an output classification indicating comfort or discomfort. During any period between temperature polling, the classification may remain indicating comfort, and the processor 104 may keep the thermoelectric cooling device activated.
At 210, the processor 104 receives feedback from user responsive to the activation of the thermoelectric device. The feedback may be a temperature adjustment Upon reaching a point of discomfort, the user may provide the temperature adjustment to the mouse system. The user feedback may be used as a classification to train the machine learning as which combinations of the first input, second input, and third input equates to user comfort and discomfort. As such, the machine learning model may activate the thermoelectric cooling device while the input corresponds to a “comfort” classification. Once the classification changes, based on inputs, to “discomfort” the machine learning model may deactivate the thermoelectric device.
At 212, the processor 104 inputs feedback, first input, second input, and third input into the machine learning model. The combination of the first input, second input, third input and the feedback may be input into the machine learning model as training data to classify the discomfort.
In another implementation, the processor 104 determine a temperature gradient between the first input and the second input. Additionally, temperature gradients based on the first input and second input may be calculated and provided as additional data points for the machine learning model. These inputs may be determinative for classification output of the machine learning model. In another example, with a mouse or point device may include more than one individually controllable thermoelectronic cooling devices within the mouse. Additionally, more corresponding sensors may be implemented across various locations on the surface of the mouse. A gradient map of the hand may be generated based on difference recorded at each of the sensor locations and the thermoelectric cooling devices may be be individually activated to generate heat or cooling to any part of the gradient map that may be above or below the comfort range.
In this implementation, the processor 104 inputs the temperature gradient, feedback, first input and second input into the machine learning model. By providing the additional data point of the temperature gradient, the machine learning model may be able to be trained to be more accurate in classifying combination of temperatures as inputs.
The processor 104 inputs the ambient temperature, the feedback, first input and second input into the machine learning model. In this implementation, ambient temperature may become a determinative factor in the classification of comfort versus discomfort. The ambient temperature may be determinative because fingers with bad circulation may feel colder to a user when the ambient temperature is lower; thereby decreasing comfort. A user may activate or deactivate the thermoelectric cooling device based on the ambient temperature in conjunction with the temperatures recorded on the mouse system itself.
