Description

Technical Field

[0001] The present invention relates to a user interface device for use in a lighting system. The present invention also relates to a lighting system comprising the user interface device. The present invention also relates to a method of providing a user interface on a user interface device, and a computer program product for executing the method. Background Art

[0002] Home and professional environments may contain a large number of lighting devices for creating ambient lighting, mood lighting, accent lighting or task lighting. These lighting devices may be controlled via a (wireless) network, for example by a smart device such as a smartphone or a (central) control panel. Such user interface devices typically include a display showing the controllable lighting devices.

[0003] Some types of lighting devices, such as spotlights or table lamps, can be manipulated by the user. The user can manually change the orientation by simply reorienting the lighting device. Other types of lighting devices, such as table lamps or portable lamps, or (spot) lamps in power rail systems, can be repositioned by the user. Summary of the invention

[0004] The inventors have appreciated that when a lighting system has multiple lighting devices, a user interface of a user interface device may become cluttered and it may be difficult for a user to identify a specific lighting device. The inventors have also appreciated that it may be beneficial to indicate on the user interface which lighting device has been recently repositioned (e.g. moved or reoriented), especially for repositionable lighting devices. This enables the user to immediately see which lighting device the user has interacted with, thereby reducing the time it takes the user to find the lighting device on the user interface and thereby improving the user experience of controlling a lighting device of a lighting system comprising multiple lighting devices. Therefore, one object is to improve the user experience of controlling a lighting device of a lighting system comprising multiple lighting devices.

[0005] According to a first aspect, the object is achieved by a user interface device for use in a lighting system comprising a plurality of lighting devices, each lighting device being repositionable by a user and each lighting device comprising a motion sensor configured to detect motion of the respective lighting device, the user interface device comprising:

[0006] -monitor,

[0007] - a receiver configured to receive one or more input signals indicative of movement of a lighting device of the plurality of repositionable lighting devices,

[0008] - a processor configured to:

[0009] determining which lighting device has been most recently repositioned based on the one or more input signals,

[0010] presenting a plurality of virtual representations of the plurality of lighting devices on a display, and

[0011] An indication is presented on the display indicating lighting devices that have recently been repositioned.

[0012] The processor is configured to determine which lighting device has been recently repositioned based on one or more input signals. The one or more input signals may indicate a time when (one or more) lighting devices have been repositioned or touched. For example, the one or more input signals may include data indicating a time when (one or more) lighting devices have been repositioned, or the processor may be configured to determine at which moment the one or more input signals have been received. The processor is also configured to present multiple virtual representations of multiple lighting devices on a display along with an indication of the lighting devices that have recently been repositioned. This is beneficial because a user can immediately see which lighting device the user has recently interacted with. This reduces the time it takes for the user to find the lighting device on the user interface, and it improves the user experience of controlling the lighting device.

[0013] The motion sensor may be configured to detect movement of the respective lighting device, and the processor may be configured to determine which lighting device has been recently moved based on one or more input signals. The movement may be, for example, a touch movement of a user, or a change in the position or orientation of the lighting device by the user. This is beneficial because the user can immediately see which lighting device the user has recently moved. Additionally or alternatively, the motion sensor may be configured to detect the orientation of the respective lighting device, and the processor may be configured to determine which lighting device has recently been redirected based on one or more input signals. The user may redirect the lighting device, and this may be detected with the motion sensor. This is beneficial because the user can immediately see which lighting device the user has recently redirected.

[0014] The processor can be configured to receive user input from the user via the user interface and control the lighting device that has been recently repositioned based on the user input. This is beneficial because it enables the user to immediately control the lighting device that has been recently repositioned, thereby reducing the time the user controls the lighting device via the user interface and further improving the user experience of controlling the lighting device.

[0015] The processor can be configured to determine when the plurality of lighting devices have been repositioned based on the one or more input signals, present a list of the plurality of virtual representations of the plurality of lighting devices on the display, and determine an order of the list according to when the plurality of lighting devices have been repositioned. The plurality of virtual representations of the plurality of lighting devices can be ordered from most recently repositioned to oldest repositioned.

[0016] The processor may be configured to determine when the plurality of lighting devices have been repositioned based on the one or more input signals, and to group the plurality of lighting devices into one or more groups based on when the plurality of lighting devices have been repositioned. The processor may, for example, be configured to select a subset of lighting devices in the plurality of lighting devices that have been repositioned during a (first predefined) time period, and to group the subset of lighting devices into a group.

[0017] Additionally, the processor may be configured to select a second subset of lighting devices of the plurality of lighting devices that have been repositioned during the second time period and group the second subset of lighting devices into a second group. This is beneficial because the lighting devices are automatically grouped.

[0018] The processor may also be configured to present a virtual representation of the group(s) on the display.

[0019] Additionally or alternatively, the processor can be configured to obtain location information indicating the locations of the plurality of lighting devices, and further group the plurality of lighting devices into one or more groups based on the locations of the plurality of lighting devices. The processor can, for example, group lighting devices located within a predefined proximity in the same group.

[0020] The processor may be configured to determine a light setting for controlling a lighting device that has recently been repositioned, and to control the lighting device according to the light setting after the lighting device has been repositioned, wherein the light setting is different from the light setting of other lighting devices, or wherein the light setting is a predefined light setting. This is beneficial because the lighting device indicates that it is a lighting device that has recently been repositioned.

[0021] According to a second aspect, the object is achieved by a lighting system comprising:

[0022] - a plurality of lighting devices, each lighting device being repositionable by a user and each lighting device comprising a motion sensor configured to detect motion of the respective lighting device, and

[0023] - A user interface device according to any of the above user interface devices. A plurality of lighting devices may be included in a luminaire (e.g. a ceiling mounted luminaire comprising a redirectable spotlight). A plurality of lighting devices may be arranged along a longitudinal axis of the luminaire (e.g. a luminaire or power rail comprising a plurality of linearly positioned light sources along a central axis).

[0024] According to a third aspect, the object is achieved by a method of providing a user interface on a user interface device for use in a lighting system comprising a plurality of lighting devices, each lighting device being repositionable by a user and each lighting device comprising a motion sensor configured to detect motion of the respective lighting device, the method comprising:

[0025] - receiving one or more input signals indicative of movement of a lighting device of the plurality of repositionable lighting devices,

[0026] - determining which lighting device has been recently repositioned based on one or more input signals,

[0027] - presenting on a display a plurality of virtual representations of the plurality of repositionable lighting devices, and

[0028] - presenting an indication on the display indicating lighting devices that have recently been repositioned.

[0029] According to a fourth aspect, the object is achieved by a computer program product for a computing device, the computer program product comprising a computer program code for performing the method when the computer program product is run on a processing unit of the computing device.

[0030] It should be understood that the lighting system, method, and computer program product may have similar and / or the same embodiments and advantages as the user interface device described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 An example of a lighting system 100 comprising a plurality of lighting devices 110, 120 and a user interface device 102 is schematically shown. The lighting devices 110, 120 can be repositioned by a user (not shown). The user can, for example, move or redirect the lighting devices 110, 120. Each lighting device 110, 120 comprises a respective motion sensor 112, 122 configured to detect the motion of the respective lighting device 110, 120. The user interface device 102 comprises a display 108, a receiver 104 and a processor 106. The user interface device 102 can be any type of device configured to control or configure the lighting system 100. The user interface device 102 can, for example, be a smart phone, a tablet PC, a PC, a central (home) lighting control system, etc.

[0039] The lighting devices 110, 120 are lighting devices that can be repositioned by a user. The lighting devices 110, 120 can be, for example, portable lighting devices that can be repositioned (moved) by a user, and / or the lighting devices 110, 120 can be redirected by a user. The lighting devices 110, 120 can be controlled, for example, by the processor 106 of the user interface device 102, by a central lighting control system (e.g., a bridge, a gateway, etc.), by another connected device, etc. The lighting devices 110, 120 may also include a communication unit (not shown) configured to receive lighting control commands (and optional directional control commands). The communication unit may include hardware for communicating via one or more wireless communication protocols (e.g., Bluetooth, Wi-Fi, Li-Fi, 3G, 4G, 5G, or ZigBee). A specific communication technology may be selected based on the system architecture of the lighting system. The lighting devices 110, 120 may be any type of lighting device comprising one or more (LED) light sources and a processing unit for controlling the light output (e.g., hue, saturation, and / or brightness) of the one or more light sources based on received control signals. The lighting devices 110, 120 may be arranged to provide general lighting, such as task lighting, ambient lighting, mood lighting, accent lighting, indoor lighting, outdoor lighting, etc.

[0040] The lighting devices 110, 120 may include motion sensors 112, 122 configured to detect motion of the respective lighting devices 110, 112. The motion sensors 112, 122 may be configured to detect movement of the respective lighting devices and provide a signal indicating the movement of the respective lighting devices 110, 120 to the user interface device 102. The signal may be transmitted to the user interface device 102 via a communication unit of the lighting devices 110, 120. The motion sensor may include one or more sensors such as one or more accelerometers, one or more gyroscopes, one or more magnetometers, one or more tilt sensors, etc., in order to detect motion of the lighting devices 110, 120. The motion may be a repositioning of the lighting devices 110, 120, a reorientation of the lighting devices 110, 120, a touch of the lighting devices 110, 120, etc. Such motion sensors are known in the art and therefore will not be discussed in further detail. Figure 2 An example of a lighting system is illustrated that includes a plurality of lighting devices 210, 220, 230. A user may move a lighting device 210 to a new position 210', which movement may be detected by a motion sensor of the lighting device 210. The lighting device 210 may then transmit one or more signals indicating the movement of the lighting device 210 to the user interface device 102.

[0041] Additionally or alternatively, the motion sensors 112, 122 may be configured to detect the (re)orientation of the respective (re-orientable) lighting devices 110, 120. The lighting devices 110, 120 may include respective orientation sensors configured to provide a signal indicating the (re)orientation of the respective lighting devices 110, 120 to the user interface device 102. The orientation sensor may include one or more sensors (such as one or more accelerometers, one or more gyroscopes, one or more magnetometers, one or more tilt sensors, etc.) in order to detect the orientation of the lighting devices 110, 120. The orientation of the lighting devices 110, 120 may be defined by the roll, pitch and yaw of the lighting devices 120 around the X-axis, Y-axis and Z-axis. Such orientation sensors are known in the art and will therefore not be discussed in further detail. Figure 3a-3c An example of a manually redirectable lighting device is shown in .

[0042] Figure 3a An example of a luminaire 300 is shown that includes a plurality of redirectable luminaires 310, 320, each of which includes an orientation sensor (not shown). The luminaire 300 includes a base 306, and each luminaire 310, 320 is configured to rotate about a respective axis 302, 304. The luminaires 310, 320 may also be tiltable. Figure 3b An alternative luminaire 330 is shown, wherein the luminaire includes a plurality of luminaires 332. The plurality of luminaires 332 are arranged along a longitudinal axis 312 of the luminaire 330. The luminaires 332 are rotatable along the longitudinal axis 312 of the luminaire 330. The luminaires 332 may each include an orientation sensor configured to detect an orientation of the respective luminaire. Figure 3b An alternative re-orientable lighting device 340 is shown. The lighting device 340 including an orientation sensor can be placed on the surface 308, and a user can change the orientation of the lighting device 340. For example, the lighting device 340 can be a portable lighting device.

[0043] The user interface device 102 includes a receiver 304 (communication unit) configured to receive one or more input signals indicating the movement of the lighting devices 110, 120 in the plurality of repositionable lighting devices 110, 120. The one or more input signals may be received directly or indirectly from the lighting devices 110, 120, such as via an intermediate device such as a bridge, a gateway, a remote server, etc. The receiver 104 may include hardware for communicating via one or more communication protocols (e.g., Bluetooth, Wi-Fi, Li-Fi, 3G, 4G, 5G, or ZigBee). The one or more input signals indicate the movement of the lighting device. The one or more input signals may be generated by the lighting device, and the lighting device may transmit the signal to the user interface device 102. The one or more input signals may be emitted by the lighting device when the lighting device is repositioned.

[0044] The user interface device 102 includes a processor 106 (e.g., a microcontroller, circuit, microchip, etc.). The processor 106 is configured to determine which lighting device has been recently repositioned based on one or more input signals. The one or more input signals may indicate a time when the lighting device(s) have been repositioned. For example, the one or more input signals may include data indicating a time when the lighting device(s) have been repositioned, or the processor 106 may be configured to determine at which moment the one or more input signals have been received. The processor 106 is also configured to present a plurality of virtual representations 110', 120' (e.g., icons, device names, etc.) of the plurality of lighting devices 110, 120 on the display 108. The processor 106 is also configured to present an indication 160 on the display 108 indicating the lighting device 110' that has been recently repositioned. Figure 1 In the example of , indication 160 is shown as a highlight of lighting device 110. It should be understood that this is merely an example, and one skilled in the art will be able to provide other indications to indicate which lighting device has been recently repositioned. For example, processor 106 may be configured to change the color or size of the virtual representation, change the order of the list of virtual representations (e.g., by placing lighting devices that have recently been repositioned at the top), change the names of the lighting devices, provide text information indicating which lighting device has been recently repositioned, etc. Figure 1 , the user may have moved and / or reoriented lighting device 110. Lighting device 110 may transmit one or more signals indicating the movement and / or reorientation to user interface device 102. Based on the one or more signals, processor 106 may determine that lighting device 110 has recently been repositioned and indicate this on display 108 by presenting indication 160 at virtual representation 110' of lighting device 110.

[0045] The processor 106 may be configured to receive user input from the user via the user interface and control the lighting device that has recently been repositioned based on the user input. This enables the user to immediately control the lighting device 110 that has recently been repositioned. The user may, for example, provide input to change the hue, saturation or brightness of the lighting device 110 that has recently been repositioned, or to select a (dynamic) light scene for the lighting device 110 that has recently been repositioned. The user interface may be a display, which may include a touch-sensitive surface. Alternatively, the user interface may be another user interface, such as a voice interface, a rotary dimmer, a light switch, etc.

[0046] The processor 106 may be configured to determine when the plurality of lighting devices 110, 120 have been repositioned based on one or more input signals and present a list of the plurality of virtual representations of the plurality of lighting devices on the display 108. The processor 106 may be configured to determine an order of the list based on when the plurality of lighting devices have been repositioned. The processor 106 may determine the order such that the virtual representations of the plurality of lighting devices are ordered from most recently repositioned to oldest repositioned. Figure 1 , the user may, for example, first reposition lighting device 120, and then reposition lighting device 110. Lighting device 120 may transmit signals indicating these repositionings to user interface device 102, and processor 106 may determine when multiple lighting devices 120, 110 have been repositioned based on one or more input signals, and present a list of virtual representations accordingly (which would result in virtual representation 110' being before virtual representation 120' in this example).

[0047] The processor 106 can be configured to determine when the plurality of lighting devices 110, 120 have been relocated based on one or more input signals, and group the plurality of lighting devices 110, 120 into one or more groups based on when the plurality of lighting devices 110, 120 have been relocated. The processor 106 can store the grouping information in a memory. The memory can be included in the user interface device 102, in a central (home) lighting controller, in the lighting devices 110, 120, and the like. Figure 4 An example thereof is illustrated, wherein the lighting system comprises a Figure 3aThe processor 106 may include two luminaires 300, 400 of the luminaire. The user may redirect the lighting devices 310 and 320 of the luminaire 300. Subsequently, the user may redirect the lighting devices 410 and 420 of the luminaire 400. The processor 106 may receive a signal indicating redirection from the lighting devices 310, 320, 410, 420. Based on the lighting devices 310 and 320 having been redirected first and the lighting devices 410 and 420 having been redirected subsequently, the processor 106 may group the lighting devices 310 and 320 into a first lighting control group and group the lighting devices 410 and 420 into a second lighting control group.

[0048] The processor 106 may be configured to select a subset of the plurality of lighting devices 110, 120 that have been repositioned during a time period and group the subset of lighting devices into a group. Figure 4 The processor 106 may group the lighting devices 310, 320 of the luminaire 300 in a group if the user will redirect these lighting devices 310, 320 within a (predefined) time period.

[0049] The processor 106 may be further configured to obtain location information indicating the locations of the plurality of lighting devices 110, 120, and further group the plurality of lighting devices 110, 120 into one or more groups based on the locations of the plurality of lighting devices 110, 120. The location information may be obtained, for example, from an (indoor) positioning system (e.g., an RF-based positioning system, a VLC-based positioning system, etc.). Alternatively, the location information may be obtained from a memory storing information about the locations of the lighting devices of the lighting system. These locations may be obtained from the (indoor) positioning system, or, for example, via a user interface, wherein a user may provide input indicating the location via the user interface, for example by positioning a virtual representation (e.g., an icon) of the lighting devices 110, 120 on a map of the environment. Techniques for determining the locations of lighting devices are known in the art and will therefore not be discussed in further detail. For example, again referring to Figure 4 , if a user redirects lighting devices 310 and 320 of luminaire 300 and lighting devices 410 and 420 of luminaire 400 (e.g., over a period of time), processor 106 can group these lighting devices into two groups based on their locations; the first group includes lighting devices 310 and 320, and the second group includes lighting devices 410 and 420.

[0050] The processor 106 may be configured to determine a light setting for controlling a lighting device that has recently been repositioned, and to control the lighting device according to the light setting after the lighting device has been repositioned. The light setting may be a light setting that is different from the light settings of other lighting devices. Alternatively, the light setting may be a predefined light setting. The processor 106 may control the lighting device that has recently been repositioned according to the light setting to indicate to a user that the lighting device has recently been repositioned. The processor 106 may control the lighting device that has recently been repositioned by, for example, transmitting a lighting control command to the lighting device via a transmitter (not shown). For example, referring to Figure 1 , the user may have recently repositioned (eg, moved and / or redirected) the lighting device 110, and the processor 106 may control the lighting device 110 according to a particular light setting to indicate that the lighting device 110 has been repositioned.

[0051] Figure 5 A method 500 of providing a user interface on a user interface device is schematically shown. The user interface device is for use in a lighting system comprising a plurality of lighting devices, each lighting device being repositionable by a user, and each lighting device comprising a motion sensor configured to detect motion of the respective lighting device.
