Abstract

Examples relate to changing screen brightness of a computing device. One example enables determination of whether the computing device is being used for one of a set of predetermined application types. The screen brightness of the computing device may be changed based on a set of first brightness values associated with the first predetermined application type responsive to the computing device being used for a first predetermined application type and based on a set of second brightness values associated with the second predetermined application type responsive to the computing device being used for a second predetermined application type.

Description

[0001 ] Computing devices may automatically change a brightness of a screen of a device based on disparate, predetermined conditions being met. For example, a computing device may change screen brightness responsive to the device entering a power-saving mode. In another example, a computing device may change screen brightness responsive to a user manually changing screen brightness.

[0014] The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several examples are described in this document, modifications, adaptations, and other implementations are possible. Accordingly, the following detailed description does not limit the disclosed examples, instead, the proper scope of the disclosed examples may be defined by the appended claims.

[0015] A system may automatically change the brightness of a screen of a computing device based on various conditions. In some examples, the system may change screen brightness of the computing device based on usage of the computing device, proximity of a set of LED devices, any combination thereof, and/or other conditions.

[0016] The system may change screen brightness based on a set of brightness values associated with each condition. For example, the system may change screen brightness to a first brightness value for a first predetermined type of usage (e.g., a first predetermined application type running on the computing device) and may change screen brightness to a second brightness value for a second predetermined type of usage (e.g., a second predetermined application type running on the computing device). In another example, the system may change screen brightness to a first brightness value responsive to a first LED device being used within a predetermined proximity of the computing device and may change its screen brightness to a second brightness value responsive to a second LED device (or second set of LED devices) being used within a predetermined proximity of the computing device.

[0017] The system may revise a set of brightness values associated with a condition. The system may revise the set of brightness values based on, for example, ambient light conditions, monitored pupil dilation of a user, any combination thereof, and/or other factors that may affect user experience of the computing device.

[0018] Referring now to the drawings, FIG. 1 is a block diagram of an example system 100 for changing screen brightness of a computing device 101 . Computing device 101 may be a notebook, desktop, tablet, workstation, mobile device, retail point of sale device, smartphone, all-in-one (AiO) computer, gaming device, or any other device suitable for executing the functionality described below. In the example depicted in FIG. 1 , computing device 101 includes a non-transitory machine-readable storage medium 120 and a processor 1 10.

[0019] Processor 1 10 may be one or more central processing units (CPUs), microprocessors, and/or other hardware devices suitable for retrieval and execution of instructions stored in machine-readable storage medium 120. Processor 1 10 may fetch, decode, and execute program instructions to enable changing screen brightness of a computing device, as described below. As an alternative or in addition to retrieving and executing instructions, processor 1 10 may include one or more electronic circuits comprising a number of electronic components for performing the functionality of one or more of instructions.

[0020] In one example, the program instructions can be part of an installation package that can be executed by processor 1 10 to implement the functionality described herein. In this case, memory 120 may be a portable medium such as a CD, DVD, or flash drive or a memory maintained by a computing device from which the installation package can be downloaded and installed. In another example, the program instructions may be part of an application or applications already installed on computing device 100.

[0021 ] Machine-readable storage medium 120 may be any hardware storage device for maintaining data accessible to computing device 100. For example, machine-readable storage medium 120 may include one or more hard disk drives, solid state drives, tape drives, and/or any other storage devices. The storage devices may be located in computing device 101 and/or in another device in communication with computing device 101 . For example, machine-readable storage medium 120 may be any eiectronic, magnetic, optical, or other physical storage device that stores executable instructions. Thus, machine-readable storage medium 120 may be, for example, Random Access Memory (RAM), an Electrically-Erasable Programmable Read-Only Memory (EEPROM), a storage drive, an optical disc, and the like. As described in detail below, machine-readable storage medium 120 may be encoded with executable instructions for changing screen brightness of a computing device. As detailed below, storage medium 120 may maintain and/or store the data and information described herein.

[0022] In some examples, the storage medium 120 may store information related to the set of conditions based on which the system 100 may change the screen brightness of the computing device 101 . The set of conditions may include, for example, usage of predetermined application types, proximity of LED devices, and/or other conditions. Predetermined application types may comprise, for example, gaming, multimedia usage, reading, and/or other predetermined application types, in some examples, a condition may comprise occurrence of multiple events (e.g., usage of a predetermined application type and determination of a predetermined amount of ambient light, proximity of multiple LED devices, usage of a predetermined application type and proximity of an LED device, and/or occurrence of other events at a same time).

[0023] The storage medium 120 may also store sets of brightness values, such that an individual set of brightness values may correspond to an individual condition. For example, for a first predetermined application type that may be stored in the storage medium 120, the storage medium 120 may store a set of first brightness values 121 that may correspond to the first predetermined application type. Similarly, for a second predetermined application type, the storage medium 120 may store a set of second brightness values 122. An individual set of brightness values may comprise a single brightness value to which the screen brightness of the computing device 100 should be changed responsive to the individual condition met, may comprise a linear scale of values that correspond to different factors that may affect the predetermined application type, may comprise a curve representing values that correspond to the different factors, may comprise a function by which a value may be determined, and/or may otherwise represent a set of brightness values for screen brightness of a computing device. In some examples, a factor may include an ambient light value determined by the computing device 10(3, a monitored pupil dilation value of a user, time of usage, current location of the computing device, user of the computing device, and/or other factors.

[0024] As discussed further below, responsive to the system 100 determining that a condition for changing screen brightness has been met, the system 100 may determine the brightness value to which the screen brightness of the computing device 100 should be changed based on the set of brightness values associated with the condition.

[0025] As detailed below, system 100 may comprise computing device 101 . Computing device 101 may include a series of engines 130-140 for changing screen brightness of the computing device. Each of the engines may generally represent any combination of hardware and programming. For example, the programming for the engines may be processor executable instructions stored on a non-transitory machine- readable storage medium and the hardware for the engines may include at least one processor of the computing device 101 to execute those instructions. In addition or as an alternative, each engine may include one or more hardware devices including electronic circuitry for implementing the functionality described below.

[0028] In some examples, system 100 may also comprise a camera that may be used in changing the screen brightness of the computing device 101 (e.g., as described below with respect to FIG. 3).

[0027] Returning to FIG. 1 , usage determination engine 130 may determine whether the computing device 101 is being used for one of the set of predetermined application types. For example, usage determination engine 130 may determine the current usage of the computing device 101 (e.g., the application being displayed on the screen of the computing device 101 ). Usage determination engine 130 may compare the determined application with the set of predetermined application types stored in the storage medium 120.

[0028] Brightness adjustment engine 140 may change the screen brightness of the computing device 101 responsive to determining that a condition stored in the storage medium 120 has been met. For example, brightness adjustment engine 140 may change the screen brightness of the computing device 101 based on a set of first brightness values associated with a first predetermined application type responsive to the usage determination engine determining that the computing device 101 is being used for that first predetermined application type.

[0029] As mentioned above, an individual set of brightness values may comprise a single brightness value to which the screen brightness of the computing device 101 should be changed responsive to the individual condition met, may comprise a linear scale of values that correspond to different factors that may affect the predetermined application type, may comprise a curve representing values that correspond to the different factors, may comprise a function by which a value may be determined, and/or may otherwise represent a set of brightness values for screen brightness of a computing device.

[0030] Responsive to the set of brightness values associated with the first predetermined application type comprising a single individual brightness value, the brightness adjustment engine 140 may change the screen brightness of the computing device 101 to that single individual brightness value.

[0031 ] Responsive to the set of brightness values associated with the first predetermined application type comprising a linear scale of values that correspond to different factors that may affect the predetermined application type, the brightness adjustment engine 140 may determine the factors associated with the predetermined application type and the corresponding values associated with those factors. For example, the brightness adjustment engine 140 may access the factors, the values, and/or other related information from the storage medium 120. Based on the factors and their corresponding values, the brightness adjustment engine 140 may change the screen brightness of the computing device 101 to a brightness value on the linear scale of values.

[0032] Responsive to the set of brightness values associated with the first predetermined application type comprising a curve representing values that correspond to the different factors, the brightness adjustment engine 140 may determine the factors associated with the predetermined application type and the corresponding values associated with those factors. For example, the brightness adjustment engine 140 may access the factors, the values, and/or other related information from the storage medium 120. Based on the factors and their corresponding values, the brightness adjustment engine 140 may change the screen brightness of the computing device 101 to a brightness value of the curve.

[0033] Responsive to the set of brightness values associated with the first predetermined application type comprising a function by which a value may be determined, the brightness adjustment engine 140 may determine the factors associated with the predetermined application type and the corresponding values associated with those factors. For example, the brightness adjustment engine 140 may access the factors, the values, and/or other related information from the storage medium 120. Based on the factors and their corresponding values, the brightness adjustment engine 140 may change the screen brightness of the computing device 101 to a brightness value calculated using the function.

[0034] In some examples, a factor may include an ambient light value determined by the system 100, a monitored pupil dilation of the user, time of usage, current location of the computing device, a user of the computing device 101 , and/or other factors.

[0035] The brightness adjustment engine 140 may change the screen brightness of the computing device 101 in other ways based on the set of brightness values, and is not limited to the examples described herein. [0036] Referring now to the drawings, FIG. 2 is a block diagram of an example system 200 for changing screen brightness of a computing device 201 . Computing device 201 may be a notebook, desktop, tablet, workstation, mobile device, retail point of sale device, smartphone, all-in-one (AiO) computer, gaming device, or any other device suitable for executing the functionality described below. In the example depicted in FIG. 2, computing device 201 includes a processor 220 and a machine- readable storage medium 210.

[0037] Processor 220 may be one or more central processing units (CPUs), microprocessors, and/or other hardware devices suitable for retrieval and execution of instructions stored in machine-readable storage medium 220. Processor 220 may fetch, decode, and execute program instructions to enable changing screen brightness of a computing device, as described below. As an alternative or in addition to retrieving and executing instructions, processor 220 may include one or more electronic circuits comprising a number of electronic components for performing the functionality of one or more of instructions.

[0038] In one example, the program instructions can be part of an installation package that can be executed by processor 220 to implement the functionality described herein. In this case, memory 220 may be a portable medium such as a CD, DVD, or flash drive or a memory maintained by a computing device from which the installation package can be downloaded and installed, in another example, the program instructions may be part of an application or applications already installed on computing device 201 .

[0039] Machine-readable storage medium 220 may be any hardware storage device for maintaining data accessible to computing device 201 . For example, machine-readable storage medium 220 may include one or more hard disk drives, solid state drives, tape drives, and/or any other storage devices. The storage devices may be located in computing device 201 and/or in another device in communication with computing device 201 . For example, machine-readable storage medium 220 may be any electronic, magnetic, optical, or other physical storage device that stores executable instructions. Thus, machine-readable storage medium 220 may be, for example, Random Access Memory (RAM), an Electrically-Erasable Programmable Read-Oniy Memory (EEPROM), a storage drive, an optical disc, and the like. As described in detail below, machine-readable storage medium 220 may be encoded with executable instructions for changing screen brightness of a computing device. As detailed below, storage medium 220 may maintain and/or store the data and information described herein.

[0040] The storage medium 220 may store information related to the set of conditions based on which the system 200 may change screen brightness of the computing device 201. The storage medium 220 may store sets of brightness values, such that an individual set of brightness values may correspond to an individual condition. The information stored by storage medium 220 may be the same as or similar to the information stored by storage medium 120.

[0041 ] As discussed further below, responsive to the system 200 determining that a condition for changing screen brightness has been met, the system 200 may determine the brightness value to which the screen brightness of the computing device 201 should be changed based on the set of brightness values associated with the condition.

[0042] As detailed below, system 200 may comprise a computing device 201 . Computing device 201 may include a series of engines 230-240 for changing screen brightness of the computing device. Each of the engines may generally represent any combination of hardware and programming. For example, the programming for the engines may be processor executable instructions stored on a non-transitory machine- readable storage medium and the hardware for the engines may include at least one processor of the computing device 201 to execute those instructions. In addition or as an alternative, each engine may include one or more hardware devices including electronic circuitry for implementing the functionality described below.

[0043] In some examples, system 200 may also comprise a camera that may be used in changing the screen brightness of the computing device 201 (e.g., as described below with respect to FIG. 3).

[0044] LED determination engine 230 may determine whether a set of LED devices is being used within a predetermined proximity of the computing device 201 . In some instances, the system 200 and/or the LED determination engine 23(3 may be aware of a predetermined set of LED devices that may be in proximity of the computing device 201. For example, the computing device 201 may have stored thereon an API for each of the predetermined set of LED devices, in this example, the LED determination engine 230 may determine whether an individual LED device is within a predetermined proximity of the computing device 201 by determining whether the API associated with that individual LED device is being accessed. in some examples, the LED determination engine 230 may also determine a predetermined proximity of the LED device whose API is being accessed based on information obtained from the API, based on sensors, cameras, and/or other equipment of the computing device 201 , and/or in other ways.

[0045] In some examples, the storage medium 220 may store a different distance for each predetermined LED device, such that a first device may need to be within a first distance of the computing device 201 to be considered within the predetermined proximity, whereas a second device may need to be within a second distance different from the first distance to be considered within the predetermined proximity.

[0046] Brightness adjustment engine 240 may change the screen brightness of the computing device 201 responsive to determining that a set of LED devices are within a predetermined proximity of the computing device. For example, the brightness adjustment engine 240 may change the screen brightness based on a set of first LED brightness values associated with a first LED device within a predetermined proximity of the computing device 201 and a determined ambient light value responsive to LED determination engine 230 determining that the first LED device is used within the predetermined proximity of the computing device 201. The brightness adjustment engine 240 may determine the ambient light value using a camera, sensor, and/or other equipment that may determine an ambient light value.

[0047] In some examples, the brightness adjustment engine 240 may change the screen brightness of the computing device 201 responsive to determining that multiple LED devices are within a predetermined proximity to the computing device. For example, the brightness adjustment engine 240 may change the screen brightness of the computing device 201 responsive to determining that a first LED device and a second LED device are within a predetermined proximity to the computing device 200.

[0048] The brightness adjustment engine 240 may change the screen brightness of the computing device 201 based on a set of first brightness values associated with a first LED device responsive to the LED determination engine 230 determining that the first LED device is being used within a predetermined proximity of the computing device 201.

[0049] As mentioned above, an individual set of brightness values may comprise a single brightness value to which the screen brightness of the computing device 201 should be changed responsive to the individual condition met, may comprise a linear scale of values that correspond to different factors that may affect the predetermined application type, may comprise a curve representing values that correspond to the different factors, may comprise a function by which a value may be determined, and/or may otherwise represent a set of brightness values for screen brightness of a computing device.

[0050] Responsive to the set of brightness values associated with the first predetermined application type comprising a single individual brightness value, the brightness adjustment engine 240 may change the screen brightness of the computing device 201 to that single individual brightness value.

[0051 ] Responsive to the set of brightness values associated with the first predetermined application type comprising a linear scale of values that correspond to different factors that may affect the predetermined application type, the brightness adjustment engine 240 may determine the factors associated with the predetermined application type and the corresponding values associated with those factors. For example, the brightness adjustment engine 240 may access the factors, the values, and/or other related information from the storage medium 220. Based on the factors and their corresponding values, the brightness adjustment engine 240 may change the screen brightness of the computing device 201 to a brightness value on the linear scale of values.

[0052] Responsive to the set of brightness values associated with the first predetermined application type comprising a curve representing values that correspond to the different factors, the brightness adjustment engine 240 may determine the factors associated with the predetermined application type and the corresponding values associated with those factors. For example, the brightness adjustment engine 240 may access the factors, the values, and/or other related information from the storage medium 220.
