Aspects of the present disclosure are described below with reference to the accompanying drawings.

Fig. 1 shows a schematic diagram of an example system in which various methods described herein may be implemented, as shown in fig. 1, the example system including: a computer device 100 and a user 200. The user 200 faces the computer apparatus 100 to manipulate the computer apparatus 100.

The millimeter wave radar module is arranged on the computer device 100, and can monitor the motion of the tiny objects, such as the heart beat of the human body and the tiny breast fluctuation caused by respiration, and the heart rate and the respiration rate of the human body are obtained through signal processing.

The field of view 110 of the millimeter wave radar module covers at least the chest area of the user. The millimeter wave radar module transmits radio frequency signals and receives signals reflected by a user. The millimeter wave radar module detects vital sign signals of the user 200, which may include heart rate, respiration rate, etc., based on the transmitted and reflected signals. The computer device 100 determines whether the user 200 is abnormal based on the vital sign signal detected by the millimeter wave radar module, and alerts the user 200 when the abnormality occurs.

As an example, the millimeter wave radar module transmits a chirp to the chest area of the user 200. The reflected signal is phase modulated due to the motion of the chest. Modulation covers all components of motion, including heartbeat and respiration induced motion. The millimeter wave radar module transmits a plurality of chirp pulses according to a predetermined time interval. Each pulse is subjected to a distance Fast Fourier Transform (FFT) and a distance bin corresponding to the user's chest position is selected. Each chirp records the phase of the signal in the selected range bin. From this, the phase change and thus the speed are calculated. The obtained velocity still includes all motion components. By performing a doppler FFT to perform spectral analysis on the obtained velocity, various components can be resolved. It should be understood that the millimeter wave radar module may use other methods to obtain vital sign signals of the user 200, such as heart rate, respiration rate, etc., which is not limited in this embodiment.

In some possible embodiments, millimeter wave radar module may be removably coupled to computer device 100, for example, by direct connection via an interface such as USB, or by connection via a USB cable or the like. In some possible embodiments, the millimeter wave radar module is wirelessly connected to the computer device 100, for example, by NFC, bluetooth, zigbee, or other short-range wireless communication. In some possible embodiments, millimeter-wave radar module is integrated with computer device 100.

In some possible embodiments, the computer device 100 is a unitary desktop computer, wherein several components, such as a host computer, a display, etc., are integrated, and as an example, the millimeter wave radar module may be integrated into a front panel of the unitary desktop computer such that its field of view covers at least the chest area of the user 200.

In some possible embodiments, computer device 100 is a separate desktop computer that includes a host and a display, etc., as an example, millimeter wave radar module may be integrated with the host and/or the display of the separate desktop computer. In the case where the host computer is placed on a table, the millimeter wave radar module is integrated with the host computer, and the field of view thereof may cover the chest area of the user 200. In the case where the host is placed under a table, the millimeter wave radar module is integrated into the display, and its field of view may cover the chest area of the user 200.

In some possible embodiments, the computer device 100 is a notebook computer, also referred to as a laptop, notebook, palmtop or laptop, as an example, the millimeter wave radar module may be integrated at the edge of the screen of the notebook computer, for example, disposed near the camera.

Fig. 2 shows a schematic block diagram of a computer device according to an exemplary embodiment of the present disclosure, which, as shown in fig. 2, comprises: millimeter wave radar module and circuitry. The circuit system is connected with the millimeter wave radar module. As an embodiment, the circuitry may include a processor; and a memory storing a program, wherein the program includes instructions that, when executed by the processor, cause the processor to perform a user monitoring method.

The user monitoring method is described below.

Fig. 3 illustrates a flowchart of a user monitoring method according to an exemplary embodiment of the present disclosure, and as shown in fig. 3, the user monitoring method includes steps S301 to S303.

Step S301, the computer device obtains a vital sign signal of the user detected by the millimeter wave radar module, wherein the vital sign signal comprises a heart rate and/or a respiration rate.

Step S302, the computer device determines whether the user is abnormal according to the vital sign signal.

Step S303, the computer device prompts the user when the user is abnormal.

By adopting the user monitoring method, non-contact monitoring can be realized through the millimeter wave radar module, whole-course monitoring can be automatically carried out in the use process of a user, the user does not need to wear related equipment, and the situation that monitoring cannot be carried out due to forgetting to wear the equipment is avoided. Furthermore, under the condition that the user is determined to have abnormity according to the vital sign signals, the user is prompted, so that the user can know that the vital sign of the user is abnormal, and the user can have a rest in time.

As one possible implementation, prompting the user may include displaying a graphical user interface on a display of the computer device with exception information indicating an abnormal condition of the user. Generally, a user can quickly notice information on a display screen of a display while watching the display screen of the display and displaying abnormal information indicating abnormal conditions of the user on the display during a transaction using a computer device.

As a possible implementation, prompting the user may include playing a voice to prompt the user that an anomaly exists. In an office scenario, playing voice may cause interference to other users, and as an example, whether a computer device is connected to an earphone may be detected, and in a case that the computer device is connected to the earphone, the voice is played on the earphone for prompt, so that interference of playing voice to other users may be avoided.

As a possible implementation manner, the computer device further determines the abnormality degree in case that it is determined that there is an abnormality in the user according to the vital sign signal. The degree of abnormality includes a predefined plurality of discrete levels of abnormality.

As an example, at one or more exception levels, a graphical user interface with exception information is displayed on a display of the computer device to prompt a user; at one or more exception levels higher than the exception level, a graphical user interface with exception information is displayed on a display of the computer device to prompt the user and a voice is played to prompt the user and draw attention to the nearby user.

As another example, at one or more exception levels, a graphical user interface with exception information is displayed on a display of the computer device to prompt a user; at one or more abnormality levels higher than the abnormality level, a graphical user interface with abnormality information is displayed on a display of the nearby computer device to prompt a user of the nearby computer device to pay attention to the presence of an abnormality by the user.

In some possible embodiments, at least a portion of the functionality of the computer device is locked in the event of an abnormality in the user, such that the user suspends use of the computer device. Thus, the user can pause the transaction and continue the transaction after the rest.

In some possible embodiments, the computer device also synchronizes vital sign signals of the user to the server in real time.

As a possible implementation, the computer device determines whether there is an abnormality in the user according to the vital sign signal, including: the computer equipment judges whether the heart rate of the user is in a normal range or not, and if the heart rate of the user is not in the normal range, the user is determined to have abnormality.

As a possible implementation, the computer device determines whether there is an abnormality in the user according to the vital sign signal, including: the computer equipment judges whether the breathing rate of the user is in a normal range or not, and if the breathing rate of the user is not in the normal range, the user is determined to have abnormality.

As a possible implementation, the computer device determines whether there is an abnormality in the user according to the vital sign signal, including: the computer equipment judges whether the heart rate of the user is in a normal range or not and whether the breathing rate of the user is in a normal range or not, and if the breathing rate of the user and the breathing rate of the user are not in the normal range, the user is determined to be abnormal.

An exemplary arrhythmia detection is described below.

Since the user is inactive, i.e. the user is in a relatively still standing or sitting position, the heart rate is usually between 60-100 beats/min, and if the heart rate of the user is higher or lower than this range, e.g. higher or equal to 120 beats/min, it can be determined that the heart rate of the user is not within the normal range. As an example, it may be detected whether the user's heart rate exceeds a preset high heart rate value or is below a preset low heart rate value for a duration of time longer than a preset duration, and if the user's heart rate exceeds the preset high heart rate value or is below the preset low heart rate value for a duration of time longer than the preset duration, it may be determined that the user's heart rate is abnormal.

Because the user is in the active state rhythm of the heart can rise, the rhythm of the heart is higher than high rhythm of the heart default value this moment and can be considered normal phenomenon, in order to avoid the false trigger suggestion, as a possible implementation mode, the computer equipment still can acquire the activity signal that millimeter wave radar detected, whether the user is in the active state based on the activity signal is confirmed, if the user is in the active state, and the user's rhythm of the heart exceeds high rhythm of the heart default value, can confirm that the user's rhythm of the heart is normal.

As one example, the abnormality level is determined based on the degree to which the heart rate exceeds a high heart rate preset value or falls below a low heart rate preset value.

An exemplary breath rate abnormality confirmation is described below.

The normal adult respiratory rate is 12-20 times per minute. Slowed respiration is commonly seen in decreased metabolic rate, shock, and significant intracranial pressure elevation. The rapid respiration is mainly seen in fever, pain, anemia, hyperthyroidism, heart failure, pneumonic pulmonary embolism, pleuritis, bronchial asthma, neurological and mental disorders and the like.

As an example, it may be detected whether the user's respiration rate exceeds a preset high respiration rate value or is lower than a preset low respiration rate value for a time period longer than a preset time period, and if the user's respiration rate exceeds the preset high respiration rate value or is lower than the preset low respiration rate value for a time period longer than the preset time period, it is determined that the user's respiration rate is abnormal.

As one example, the abnormality level is determined based on the degree to which the respiration rate exceeds a high respiration rate preset value or falls below a low respiration rate preset value.

Fig. 4 illustrates another flowchart of a user monitoring method according to an exemplary embodiment of the present disclosure, and as shown in fig. 4, the user monitoring method includes steps S401 to S403.

Step S401, the computer device obtains a vital sign signal of the user, which is detected by the millimeter wave radar module, wherein the vital sign signal comprises a heart rate and/or a respiratory rate.

Step S402, the computer device determines whether the user is abnormal according to the vital sign signal.

As an example, it may be detected whether the user's heart rate exceeds a preset high heart rate value or is below a preset low heart rate value for a duration of time longer than a preset duration, and if the user's heart rate exceeds the preset high heart rate value or is below the preset low heart rate value for a duration of time longer than the preset duration, it may be determined that the user's heart rate is abnormal.

Because the user is in the activity state rhythm of the heart can rise, the rhythm of the heart is higher than the high rhythm of the heart default value this moment can be considered normal phenomenon, in order to avoid the false trigger suggestion, as a possible implementation mode, the computer equipment still can acquire the activity signal that millimeter wave radar detected, whether the user is in the activity state is confirmed based on the activity signal, if the user is in the activity state, and the user's rhythm of the heart exceeds the high rhythm of the heart default value, can confirm that the user's rhythm of the heart is normal.

As an example, it may be detected whether the user's breathing rate exceeds a preset high breathing rate value or is below a preset low breathing rate value for a duration exceeding a preset duration, and if the user's breathing rate exceeds the preset high breathing rate value or is below the preset low breathing rate value for a duration exceeding the preset duration, it may be determined that the user's breathing rate is abnormal.

Step S403, the computer device prompts the user and triggers the warning mechanism when the user is abnormal.

The early warning mechanism is used for sending abnormal information to a related party of the computer equipment, and the abnormal information indicates the abnormal condition of a user.

As a possible implementation, the trigger pre-warning mechanism includes: the computer equipment sends a trigger message comprising the abnormal information to the server, and the server starts an early warning mechanism in response to receiving the trigger message and sends the abnormal information to the correlative party of the computer equipment.

The associated parties may include enterprise managers, family members of users, guardians, security personnel, and the like. The transmission mode of the exception information may include, but is not limited to, telephone, instant messaging, etc.

As a possible implementation manner, the computer device further determines the abnormality degree in case that the user is determined to have abnormality according to the vital sign signal. The degree of abnormality includes a predefined plurality of discrete levels of abnormality.

As an example, at one or more exception levels, the user is prompted; the above-described early warning mechanism is triggered at one or more anomaly levels of higher anomaly degree.

As another example, the exception levels are associated with the associated parties, and at one or more exception levels, an early warning mechanism is triggered to send exception information to the first associated party; and triggering the early warning mechanism at one or more abnormal levels with higher abnormal degrees, and sending abnormal information to the second associated party.

In some possible embodiments, at least a portion of the functionality of the computer device is locked in the event that the user has an abnormality, such that the user suspends use of the computer device. Thus, the user can pause the transaction and continue the transaction after the rest.

Fig. 5 illustrates yet another flowchart of a user monitoring method according to an exemplary embodiment of the present disclosure, and as shown in fig. 5, the user monitoring method includes steps S501 to S504.

Step S501, detecting whether the computer device is in a use state.

As one embodiment, whether the computer device is in use may be determined by detecting whether an input device, such as a keyboard, mouse, or touch pad, of the computer device receives a user input. As one embodiment, whether the computer device is in use may be determined by an application state of the application program. This embodiment does not limit this.

Step S502 is entered in the case where the computer apparatus is in a use state.

Step S502, the millimeter wave radar module is started to detect the vital sign signals of the user. Wherein the vital sign signal comprises a heart rate and/or a breathing rate.

Step S503, acquiring the vital sign signal of the user detected by the millimeter wave radar module.

Step S504, whether the user is abnormal or not is determined according to the vital sign signals.

The computer equipment performs at least one of the following operations when the user has an abnormality:

displaying a graphical user interface having exception information on a display of the computer device, the exception information indicating an exception condition of the user;

locking at least a portion of the functionality of the computer device to suspend use of the computer device by a user;

and sending a trigger message comprising the abnormal information to the server to trigger the early warning mechanism.

The server responds to the received trigger message, starts an early warning mechanism and sends abnormal information to the associated party of the computer equipment.

As one example, at one or more exception levels, the user is prompted; the above-described early warning mechanism is triggered at one or more anomaly levels of higher anomaly degree.

As another example, the exception level is associated with the associated party, and at one or more exception levels, an early warning mechanism is triggered to send exception information to the first associated party; and triggering the early warning mechanism at one or more abnormal levels with higher abnormal degrees, and sending abnormal information to the second associated party.
