Description

AREA

[0001] The subject matter disclosed herein relates to the field of information processing technology and in particular to an information processing method and an electronic device. BACKGROUND

[0002] With the development of science and technology, electronic devices have changed. In certain configurations, an electronic device can convert text written directly or indirectly onto it by users into an electronic document. For example, after a user places a piece of paper on the device and writes on it with a stylus, the electronic device's processing system can recognize user input.

[0003] In particular, the main processing unit of an electronic device can assume a first state and a second state. The main processing unit can only recognize user input in the first state. In certain configurations, the power consumption of the main processing unit in the first state may be higher than the power consumption of the processing system in the second state. For example, when the main processing unit is in the first state, the display screen of the electronic device remains on; conversely, the electronic device is off when the main processing unit is in the second state.

[0004] Therefore, the aforementioned method for detecting user input can lead to excessive power consumption by the electronic device and thus shorten the standby time of the electronic device.

[0005] From US patent 2013 / 0082937A1, a mobile device is known that is placed in an inactive and identity-protected state to securely lock the device and prevent the processing of accidental touches to its display surface. Subsequently, a processing unit of the mobile device detects an activation event triggered by an operating user. The activation event can include the physical or near-contact of a writing instrument with a touch-sensitive area of ​​the mobile device. Upon detection of the activation event, the processing unit causes the mobile device to transition from the inactive state to a lower-power state.

[0006] US patent 2014 / 0049480A1 discloses a method for determining the complexity of touch input data and for negotiating the processing of touch input from a touchscreen controller to a host processor. If the touchscreen controller determines that received touch input data is too complex for processing by the touchscreen controller, the host processor can be instructed to process the data.

[0007] From US patent 2014 / 0282214A1, a method is known that includes displaying information on the screen of an electronic device and recognizing a gesture requesting the display of information associated with an application. In response to the gesture recognition, and while the gesture continues, the requested information is displayed, and if a touch position of the gesture is associated with the first selection option, a function associated with the first selection option is executed.

[0008] US patent 2014 / 0333602A1 discloses a device with a display screen that can operate in one of several modes. In proportional mode, part of the display screen is configured to be on and another part is configured to be off.

[0009] US Patent 2005 / 0044448A1 discloses a system and method for managing power consumption and data integrity in a computer system, wherein a memory controller of the computer system records in a buffer the addresses of write operations to system memory that occur during the time when the processor is in a power-saving state.

[0010] From US patent 8,773,405 B1, a device is defined as comprising a body with an elongated housing having at least one first conductive tip at a distal end and at least one sensing electrode on the body; a capacitance sensing circuit arranged within the housing and configured to detect a capacitance of the sensing electrode to generate a proximity result in response to contact with a human body; and a signal generator circuit arranged within the housing and configured to activate a position signal in response to the proximity result, the position signal being driven at the tip of the device. SUMMARY

DETAILED DESCRIPTION

[0016] The technical diagrams in the embodiments of this disclosure are expressly and completely described below with reference to the drawings in the embodiments of this disclosure. It should be noted that the described embodiments do not represent all, but rather only some, of the embodiments. All further embodiments that those skilled in the art in this field achieve based on the embodiments and without any creative work are within the scope of protection of this disclosure.

[0017] Embodiment 1 discloses an information processing method used in an electronic device. The electronic device can be a mobile phone, a tablet computer, a tablet, or the like.

[0018] The electronic device includes at least one lane detection unit and one main processing unit.

[0019] The main processing unit has at least one first state and one second state, and the power consumption of the main processing unit in the second state is lower than the power consumption in the first state.

[0020] For example, if the main processing unit is in the first state, the electronic device operates normally and the display screen is turned on; and if the main processing unit is in the second state, the electronic device is turned off.

[0021] It is understood that the track detection unit can be a small processing system, so that its power consumption in operating mode is significantly lower than that of the main processing unit in the first state. Therefore, the detection of user track inputs is performed by the track detection unit, and the main processing unit can remain in the second state during this process.

[0022] The lane detection unit is connected to the main processing unit. Specifically, the lane detection unit can be implemented in many ways. For a specific implementation, see below. Fig. 1 a structural schematic diagram of a system 10 with the track detection unit 100 disclosed in embodiment 1 and the main processing unit 200.

[0023] In connection with Fig. As can be seen from Figure 1, the lane detection unit 100 includes a processor 100A, a sensor 100B connected to the processor 100A, a memory subunit 100C connected to the processor 100A, a switching unit 100D connected to the processor 100A, and a power source subunit 100E, which is separately connected to the processor 100A and the sensor 100B.

[0024] Here, sensor 100B detects user lane input, and the power source subunit 100E of the lane detection unit 100 is configured to connect to the battery unit 200C of the main processing unit 200. Processor 100A can control the main processing unit 200 to direct power via battery unit 200C to the power source subunit 100E.

[0025] The switching unit 100D is configured for separate connection to the application processor 200A of the main processing unit 200 and the power management unit 200B. The processor 100A can control its connection to the main processing unit 200 by controlling the opening and closing of the switching unit 100D.

[0026] The memory subunit 100C is configured to store user track input, which is to be recognized by the processor 100A.

[0027] It should be noted that the in Fig. The structure shown in Figure 1 is a schematic diagram that includes the main processing unit 200, which may be similar to an existing processing unit.

[0028] Fig. 2 is an information processing method 199 according to embodiment 1 of the present disclosure. As described in Fig. 2 The information processing procedure 199 includes access 201 to operational information relating to the track detection unit during the process of detecting a user track input by the track detection unit.

[0029] The trace detection unit can be configured to recognize text written directly or indirectly by users on the input screen of an electronic device. For example, a user can place a piece of paper on an electronic device, and the trace detection unit can recognize the user's trace input when they write on the paper, for example, using a stylus. As another example, the trace detection unit can recognize user input when a user directly uses a stylus or finger to perform swiping actions (e.g., writing) on ​​the input screen of an electronic device.

[0030] Operating information can include parameter information relating to the operating state of the track recognition unit during the user track input process. For example, operating information can include the current power level, memory volume, etc.

[0031] Procedure 199 includes triggering 202 of the main processing unit to switch from the second state to the first state when the operating information meets a predetermined condition.

[0032] Different types of operational information correspond to different predetermined conditions, and a predetermined condition can be a criterion for triggering the main processing unit to switch between states. For example, if the operational information does not meet a predetermined condition, it can indicate that the track detection unit can process the user track input it has captured. Conversely, if the operational information does meet a predetermined condition, it can indicate that the track detection unit is currently unable to process the captured user track input, or that this state may occur, and thus the main processing unit can be used to assist the track detection unit.

[0033] If the main processing unit is not performing other primary tasks unrelated to user input detection while the trace detection unit is detecting the user input, the main processing unit remains in the second state to conserve power. The main processing unit can be triggered to switch from the second state to the first state when the operational information meets a predetermined condition.

[0034] It is understood that the primary tasks mentioned above refer to tasks that require the main processing unit and can only be performed in the first state.

[0035] During the process of detecting user input, the trace detection unit can remain in the second state to conserve power if it can perform other secondary tasks unrelated to the trace detection unit. The main processing unit can then be triggered to switch from the second state to the first state when the operational information meets a predetermined condition.

[0036] Procedure 199 includes controlling 203 the main processing unit to assist the track recognition unit in processing the captured user track input.

[0037] After the main processing unit switches from the second state to the first state, the main processing unit can assist the track detection unit in processing the captured user track input.

[0038] In the present embodiment, the track detection unit is separate from the main processing unit and is used to detect user track inputs. During the process of user track input detection by the track detection unit, the main processing unit can remain in the second state. Only when the operational information associated with the track detection unit meets a predetermined condition can the main processing unit be triggered to switch from the second state to the first state and assist the track detection unit in processing the detected user track input. The power consumption of the main processing unit in the second state is lower than in the first state, thus extending the standby time of the electronic device.

[0039] During the process of detecting user track input by the track detection unit, there may be circumstances in which the main processing unit assists the track detection unit in processing the detected user track input. Embodiment 2 of the present disclosure describes a specific circumstance. In particular, in the present embodiment, Embodiment 2 includes access to operational information relevant to the track detection unit. For example, Embodiment 2 may include access to the current memory volume of the user track input stored in the memory subunit of the track detection unit.

[0040] The memory subunit of the track detection subunit can be configured to store user track input so that it can be recognized by the track detection unit. Since the total specified memory capacity of the memory subunit is fixed, the current memory volume of the user track input stored in the memory subunit of the track detection unit can be accessed to prevent the user track input from not being recognized due to insufficient memory in the memory subunit.

[0041] Depending on the memory subunit, the predetermined condition can be that the current memory volume is greater than a predetermined memory volume. This means that if the current memory volume is greater than the predetermined memory volume, it is confirmed that the operating information meets the predetermined condition, and the main processing unit is then triggered to switch from the second state to the first state. The predetermined memory volume can be specified according to an actual operating situation. For example, in one embodiment, the predetermined memory volume can be 90% of the total specified memory capacity of the memory subunit.

[0042] Accordingly, controlling the main processing unit to assist the track detection unit in processing the captured user track input may include controlling the main processing unit to read the user track input stored in the memory sub-unit.

[0043] In embodiment 2, the power consumption of electronic devices can increase in practical application if the user track inputs stored in the memory subunit are always read out by the main processing unit in the first state. To reduce power consumption, embodiment 3 of the present disclosure discloses an information processing method 300. As described in Fig. 3 includes, during the process of detecting user track inputs by the track detection unit, access 301 to the current storage volume of the user track input stored in the storage subunit of the track detection unit.

[0044] The procedure 300 also includes triggering 302 of the main processing unit to switch from the second state to the first state in response to the fact that the current storage volume is larger than the predetermined storage volume.

[0045] Procedure 300 includes controlling 303 of the main processing unit to read the user track input stored in the memory subunit.

[0046] Procedure 300 includes deleting 304 the user track inputs stored in the memory subunit.

[0047] Once the main processing unit has finished reading all user track entries stored in the memory subunit, it can indicate that a backup of the user track entries stored in the memory subunit has been saved to the main processing unit. Therefore, the user track entries stored in the memory subunit can be deleted.

[0048] The procedure 300 also includes controlling 305 the main processing unit to switch from the first state to the second state.

[0049] If the user track input stored in the memory subunit is cleared, the main processing unit can indicate that the memory subunit can continue to store user track input to be recognized by the track detection unit, and to reduce the power consumption of the main processing unit in the first state, the main processing unit can be controlled to switch from the first state to the second state.

[0050] Embodiment 4 of the present disclosure provides a description for a further specific circumstance in which the main processing unit can assist the track recognition unit in processing the captured user track input.

[0051] In particular, embodiment 4 includes access to operating information relevant to the lane detection unit. Specifically, the current level of the current source subunit of the lane detection unit is accessed.

[0052] The power source subunit of the track detection subunit can be configured to supply power during the process of detecting user track inputs by the track detection unit. To prevent the detection process from being interrupted by the track detection unit due to a low current level in the power source subunit, the current level of the track detection unit's power source subunit can be accessed.

[0053] Depending on the power source subunit, the predetermined condition can be that the current current level is lower than the predetermined first current level; that is, if the current current level is lower than the predetermined first current level, the operating information can meet the predetermined condition, and the main processing unit can then be triggered to switch from the second state to the first state. The predetermined first current level can be specified according to a real operating situation. For example, the predetermined first current level can be 10% of the total specified current level of the power source subunit.

[0054] In certain embodiments, controlling the main processing unit to assist the track recognition unit in processing the captured user track input may include controlling the main processing unit to supply power to the power source subunit.

[0055] In embodiment 4, the power consumption of electronic devices can increase if the main processing unit constantly supplies energy to the power source subunit in the first state. Therefore, embodiment 5 of the present disclosure discloses an information processing method that can be used to reduce power consumption. As shown in Fig. 4 includes a procedure 400 during the process of detecting the user track input by the track detection unit, accessing 401 to the current current level of the power source subunit.

[0056] Procedure 400 includes, if the current current level is lower than the predetermined first current level, the triggering of the main processing unit 402 to switch from the second state to the first state.

[0057] The procedure 400 also includes controlling 403 of the main processing unit to supply energy to the power source subunit.

[0058] Procedure 400 includes the determination 404 of whether the current level of the power source sub-unit has reached the predetermined current level.

[0059] The predetermined current level can be set according to a real operating situation. For example, the predetermined current level can be 85% of the total specified current level of the power source subunit.

[0060] By determining whether the current level of the power source subunit has reached the predetermined current level, it can be determined whether the power source subunit has sufficient energy to supply to the track detection unit during the process of detecting user track input. If the current level of the power source subunit does not reach the predetermined current level, the main processing unit continues to supply energy to the power source subunit.

[0061] In response to the current level reaching the predetermined current level, the procedure 400 includes controlling the main processing unit 405 to switch from the first state to the second state.

[0062] If the current level of the power source subunit reaches the predetermined current level, the main processing unit indicates that the power source subunit can provide sufficient energy to the track detection unit. To reduce the power consumption of the main processing unit, it can therefore be controlled to switch from the first state to the second state.

[0063] In certain applications, the track detection unit may be in a detection-ready state before the detection of user track inputs begins. Under certain conditions, the track detection unit may increase the power consumption of electronic devices in a detection-ready state. Embodiment 6 of the present disclosure discloses an information processing method for use in electronic devices, comprising at least one track detection unit and a main processing unit to enable the reduction of power consumption.

[0064] In certain embodiments, the track detection unit can be used in conjunction with a pen; the track detection unit can have a third state and a fourth state; the power consumption of the track detection unit in the fourth state can be lower than the power consumption of the track detection unit in the third state; and the track detection unit is in the fourth state before the recognition of the user track input begins.

[0065] It should be noted that the track detection unit may not be able to detect user track input in the fourth state, and the track detection unit may only be able to detect user track input in the third state (the detection-ready state).

[0066] According to the representation in Fig. 5 includes an information processing procedure 500 that controls 501 the track recognition unit to switch from the fourth state to the third state upon receiving a first operation related to the pen.

[0067] In this embodiment, a user can write on the input screen of an electronic device using a stylus (e.g., by using it). However, before using the stylus for writing, a first process related to the stylus can be triggered, causing the trace detection unit to enter a readiness state.

[0068] In particular, triggering the first operation with respect to the pen can be implemented in many ways. In one embodiment, a first button can be arranged on the pen, and when the user presses the first button, the electronic device receives the first operation with respect to the pen. In another embodiment, a pen holder can be arranged on the electronic device to detect whether the pen is attached to the pen holder, so that when the user removes the pen from the pen holder, the electronic device receives the first operation with respect to the pen.

[0069] Procedure 500 also includes the detection 502 of user track input while the track detection unit is in the third state. The track detection unit can detect user track input in the third state.

[0070] Procedure 500 includes access 503 to operational information relating to the track detection unit during the process of detecting user track input by the track detection unit.

[0071] Procedure 500 further includes triggering 504 of the main processing unit to switch from the second state to the first state when the operating information meets a predetermined condition.

[0072] Procedure 500 includes controlling 505 of the main processing unit to assist the track recognition unit in processing the captured user track input.

[0073] In the present embodiment, the power consumption of the electronic device can be reduced relative to other configurations because the track detection unit is in the fourth state before the start of recognizing the user track input, and the power consumption of the track detection unit in the fourth state is lower than the power consumption in the third state.

[0074] Embodiment 7 of the present disclosure includes an electronic device. The electronic device may be a mobile phone, a tablet computer, a tablet or the like.

[0075] The electronic device includes at least one track detection unit and one main processing unit. The main processing unit has at least one first state and one second state, and the power consumption of the main processing unit in the second state is lower than the power consumption in the first state.

[0076] It should be noted that the track detection unit can also be a small processing system. The power consumption of the track detection unit in the operating state can be significantly lower than the power consumption of the main processing unit in the first state. Therefore, the detection of user track inputs can be performed by the track detection unit in the present disclosure. During the process of user track input detection by the track detection unit, the main processing unit can remain in the second state.

[0077] In the present disclosure, the track detection unit can be connected to the main processing unit. In particular, the track detection unit can be implemented in many ways. For a specific implementation, reference is made to the [reference to be added]. Fig. 1. Represented embodiment.

[0078] According to the representation in Fig. 6 includes an electronic device 600, a first access module 601, a first trigger module 602 and a first control module 603.

[0079] The first access module 601 can be configured to access operational information relating to the track detection unit in the process of detecting user track input by the track detection unit.

[0081] The first control module 603 can be configured to control the main processing unit to assist the track detection unit in processing the captured user track input.

[0082] In the present embodiment, the track detection unit, separate from the main processing unit, can be used to detect user track inputs, and the main processing unit can remain in the second state during the process of user track input detection by the track detection unit. In response to the operational information associated with the track detection unit fulfilling a predetermined condition, the main processing unit can be triggered to switch from the second state to the first state and assist the track detection unit in processing the detected user track input. The power consumption of the main processing unit in the second state can be lower than the power consumption in the first state, thus extending the standby time of the electronic device.

[0083] Embodiment 8 of the present disclosure discloses a specific implementation of the first access module. In this embodiment, the first access module can be specifically configured to access the current memory volume of the user track input stored in the memory subunit of the track detection unit during the process of detecting user track inputs by the track detection unit.

[0084] The predetermined condition can be that the current memory volume is greater than a predetermined memory volume. This means that, in response to the current memory volume exceeding the predetermined memory volume, it is confirmed that the operational information has met the predetermined condition, and the main processor unit can then be triggered to switch from the second state to the first state. The predetermined memory volume can be specified according to an actual operational situation. For example, the predetermined memory volume can be 90% of the total specified memory capacity of the memory subunit.

[0085] In certain embodiments, the first control module can be specifically used to control the main processing unit in order to read the user track input stored in the memory subunit.

[0086] Embodiment 9 of the present disclosure includes an electronic device 700. As shown in Fig. 7 includes the electronic device 700 a first access module 701, a first trigger module 702, a first control module 703, a first deletion module 704 and a second control module 705.

[0090] The first erase module 704 is configured to erase the user track input stored in the memory subunit.

[0091] Once the main processing unit has finished reading all user track entries stored in the memory subunit, it can indicate that a backup of the user track entries stored in the memory subunit has been saved to the main processing unit. Therefore, the user track entries stored in the memory subunit can be deleted.

[0092] The second control module 705 is configured to control the main processing unit to switch from the first state to the second state.

[0093] When the user track input stored in the memory subunit is cleared, the main processing unit indicates that the memory subunit can continue to store user track input to be recognized by the track detection unit, and to reduce the power consumption of the main processing unit in the first state, the main processing unit can be controlled to switch from the first state to the second state.

[0094] Embodiment 10 of the present disclosure discloses a further implementation of the first access module. In this embodiment, the first access module can be configured to access the current level of the track detection unit during the process of detecting user track inputs by the track detection unit.

[0095] The predetermined condition can be that the current level is lower than the predetermined first current level; that is, in response to the current level being lower than the predetermined first current level, the operating information may have met the predetermined condition; and the main processing unit can then be triggered to switch from the second state to the first state. The predetermined first current level can be specified according to a real operating situation. For example, the predetermined first current level can be 10% of the total specified current level of the power source subunit.

[0096] In certain embodiments, the first control module is configured to control the main processing unit in order to supply power to the storage subunit.

[0097] Embodiment 11 of the present disclosure includes an electronic device 800. As shown in Fig. 8 The electronic device 800 includes a first access module 801, a first trigger module 802, a first control module 803, a first decision module 804 and a third control module 805.

[0102] The predetermined current level can be set according to the actual situation. For example, the predetermined current level can be 85% of the total specified current level of the power source sub-unit.

[0103] By determining whether the current level of the power source subunit has reached the predetermined current level, it can be confirmed whether the power source subunit has sufficient energy to supply the track detection unit during the process of detecting user track input. If the current level of the power source subunit does not reach the predetermined current level, the main processing unit can continue to supply energy to the power source subunit.

[0104] The third control module 805 is configured to control the main processing unit to switch from the first state to the second state in response to the current level reaching the predetermined current level.
