Abstract

A touch-sensitive display apparatus includes a multi-touch screen, a processor, and a network unit. The processor controls the apparatus to enter a pulse rate measuring mode, records the number of the touched touch points in each scanning period, and determines a curve according to all the recorded numbers within a preset period, the number of wave crests of the curve, and pulse rates per minute according to the number of the wave crests. A related method is also provided.

Claims

1. A touch-sensitive display apparatus comprising:

a multi-touch screen configured to detect physical contact therewith; and

a processor configured to;

control the touch-sensitive display apparatus to enter a pulse rate measuring mode;

for a plurality of scanning periods, detect a quantity of touch points on the multi-touch screen during sustained continuous contact by a user in each scanning period when in the pulse rate measuring mode;

receive the quantity of the touch points from the multi-touch screen and generate a curve according to the recorded quantity of the touch points in each scanning period within a preset period;

detect a quantity of wave crests of the curve;

determine pulse rate per minute according to the quantity of the wave crests, wherein the processor is configured to determine pulse rate per minute by determining that a quantity of an artery throbbing within the preset period is the quantity of the wave crests minus one, and determining pulse rate per minute as the quantity of the artery throbbing within the preset period divided by the preset period; and

output the determined pulse rate per minute to the multi-touch screen for displaying the determined pulse rate per minute on the multi-touch screen.

2. The touch-sensitive display apparatus as described in claim 1, wherein the preset period is one minute or more than one minute.

3. The touch-sensitive display apparatus as described in claim 1, wherein the processor is further configured to generate a prompt to indicate that the determined pulse rate per minute is abnormal when the processor is determining that the determined pulse rate per minute is not within a preset range.

4. The touch-sensitive display apparatus as described in 1, further comprising a network unit to communicate the touch-sensitive display apparatus with a network, wherein the processor is further configured to transmit the determined pulse rate per minute to a designated medical webpage through the network unit to obtain medical help information from the designated webpage when the processor is determining that the determined pulse rate per minute is not within a preset range.

5. A pulse rate measuring method applied in a touch-sensitive display apparatus, the touch-sensitive display apparatus comprising a multi-touch screen configured to detect physical contact therewith, the method comprising:

receiving, from a processor, a command at the touch-sensitive display apparatus to enter a pulse rate measuring mode;

detecting a quantity of touch points on the multi-touch screen during sustained continuous contact by a user, wherein the detecting of the quantity of the touch points occurs during a plurality of scanning periods that are each controlled by the processor;

transmitting data, corresponding to each of the plurality of scanning periods, of the quantity of the touch points to the processor;

generating, by the processor, a curve from the data of the quantity of the touch points for each scanning period;

determining a quantity of wave crests of the curve by the processor;

determining pulse rate per minute according to the quantity of the wave crests by the processor, wherein determining pulse rate per minute comprises determining a quantity of an artery throbbing within the preset period as the quantity of the wave crests minus one, and determining pulse rate per minute as the quantity of the artery throbbing within the preset period divided by the preset period; and

outputting data, from the processor, to the multi-touch screen for displaying the determined pulse rate per minute on the multi-touch screen.

6. The pulse rate measuring method as described in claim 5, wherein the preset period is one minute or more than one minute.

7. The pulse rate measuring method as described in claim 5, further comprising:

generating a prompt to indicate that the determined pulse rate per minute is abnormal by the processor when the processor is determining that the determined pulse rate per minute is not within a preset range.

8. The pulse rate measuring method as described in claim 5, further comprising:

transmitting the determined pulse rate per minute to a designated medical webpage to obtain medical help information from the designated webpage by the processor when the processor is determining that the determined pulse rate per minute is not within a preset range.
