Abstract

A portable electronic device includes an infrared touch screen and a processor. The infrared touch screen includes a detection unit, a filter unit, and a signal conversion unit. The detection unit detects the intensity of the infrared beams reflected by a user'"'"'s body part placed on the infrared touch screen, and converts the detected intensity of the infrared beam to electrical signals. The filter unit filters the electrical signals and amplifies the filtered electrical signals. The signal conversion unit converts the electrical signals to digital signals. The processor includes an information processing module and a display control module. The information processing module processes the digital signals to obtain the heart rate information of the user, and creates a heart rate monitoring result according to the heart rate information of the user. The display control module controls the infrared touch screen to display the heart rate monitoring result.

Claims

1. A portable electronic device for monitoring a heart rate of a user, comprising:

an infrared touch screen comprising;

a detection unit, configured to detect intensity of infrared beams reflected by the user'"'"'s body part placed on the infrared touch screen, and to convert the intensity of the reflected infrared beams to electrical signals;

a filter unit, configured to filter noises in the electrical signals, and to magnify the filtered electrical signals; and

a signal conversion unit, configured to convert the magnified electrical signals to digital signals; and

a processor comprising;

a data processing module, configured to process the digital signals to obtain heart rate data of the user, and to create a heart rate monitoring result according to the heart rate data of the user; and

a display control module, configured to control the infrared touch screen to display the created heart rate monitoring result.

2. The portable electronic device as described in claim 1, further comprising a storage unit storing a reference value of a human heart rate, wherein the processor further comprises an alarm module, the data processing module is further configured to compare the heart rate data of the user with the reference value of the human heart rate stored in the storage unit, and send a control signal to the alarm module if the heart rate of the user is not equal to the reference value of the human heart rate, and the alarm module controls the infrared touch screen to display alarm information when the control signal is received.

3. The portable electronic device as described in claim 1, further comprising a storage unit storing a reference value range of a human heart rate, wherein the processor further comprises an alarm module, the data processing module is further configured to compare the heart rate data of the user with the reference value range of the human heart rate stored in the storage unit, and send a control signal to the alarm module if the heart rate of the user does not fall in the reference value range, and the alarm module controls the infrared touch screen to display alarm information when the control signal is received.

4. The portable electronic device as described in claim 1, wherein the infrared touch screen comprises a monitoring region and a result displaying region, the monitoring region is configured for allowing the user to place the body part thereon for heart rate detection, and the result displaying region is configured for displaying the heart rate monitoring result.

5. The portable electronic device as described in claim 4, wherein the heart rate monitoring result is selected from the group consisting of a heart rate figure, and information of heart beat or pulse.

6. The portable electronic device as described in claim 5, wherein the information of heart beat or pulse is a number of heart beats per minute of the user.

7. The portable electronic device as described in claim 1, being a mobile terminal, electronic reader, a tablet computer, or a digital phone frame.
