Description

Head-mounted device and method for operating a head-mounted device The present invention relates to an electronic device and a method for operating an electronic device, and more particularly to a head-mounted device and a method for operating a head-mounted device. A user can enjoy audio-visual entertainment or play games through a head-mounted device. The head-mounted device is, for example, a head-mounted display. When a user enjoys audio-visual entertainment or plays games through a head-mounted device, the user cannot know the situation of the environment around the user. It can be seen therefrom that a user who is using a head-mounted device does not know that the user himself may be exposed to danger. Therefore, how to provide a head-mounted device that can detect an object that may cause harm to the user is one of the research focuses of those skilled in the art. The present disclosure provides a head-mounted device and a method for operating a head-mounted device that can detect an object that may cause harm to the user. According to an embodiment of the present disclosure, a head-mounted device is worn on a user and provides an image to the user. The head-mounted device includes a display unit, a first sensing device, and a second sensing device. The display unit displays an image. The first sensing device detects whether there is an object that may cause harm to the user within a specific range. The second sensing device captures an object image of the object, so that the display unit displays the object image. According to an embodiment of the present disclosure, a method of operation is for a head-mounted device. The head-mounted device is worn on a user and provides an image to the user. The head-mounted device includes a display unit, a first sensing device, and a second sensing device. The method of operation includes: detecting, by the first sensing device, whether there is an object that may cause harm to the user within a specific range; when it is detected that there is an object that may cause harm to the user within the specific range, capturing, by the second sensing device, an object image of the object; and controlling the display unit to display the object image. Based on the above, the present disclosure detects, by the first sensing device, whether there is an object that may cause harm to the user within a specific range, and when it is detected that there is an object that may cause harm to the user within the specific range, the display unit displays the object image of the object. In this way, the head-mounted device can know that there is an object that may cause harm to the user within a specific range, and display the object image of the object through the display unit. The safety performance of using the head-mounted device can be improved.

Please refer to FIG. 1 and FIG. 2 simultaneously. FIG. 1 is a usage scenario diagram of a head-mounted device according to an embodiment of the present disclosure. FIG. 2 is a schematic diagram of the head-mounted device according to an embodiment of the present disclosure. In this embodiment, the head-mounted device (HMD) 100 is worn on the user U and provides an image IMG to the user U. The head-mounted device 100 is, for example, any form of head-mounted display device. In this embodiment, the head-mounted device 100 includes a display unit 110, a first sensing device 120, and a second sensing device 130. The display unit 110 displays the image IMG. The first sensing device 120 detects whether there is an object OBJ that poses a hazard to the user U within a specific range PR. The second sensing device 130 captures an object image OIMG of the object OBJ, so that the display unit 110 displays the object image OIMG. Please refer to FIG. 1, FIG. 2, and FIG. 3 simultaneously. FIG. 3 is a flowchart of an operation method according to an embodiment of the present disclosure. In this embodiment, the operation method S100 is used for the head-mounted device 100. The operation method S100 includes steps S110 to S130. The user U wears the head-mounted device 100 to enjoy audio-visual entertainment or play games. The first sensing device 120 starts to detect the environment around the user U. During use, the first sensing device 120 detects in step S110 whether there is an object OBJ that may pose a hazard to the user U within a specific range PR. When the first sensing device 120 detects an object OBJ that poses a hazard to the user U within the specific range PR, the second sensing device 130 captures an object image OIMG of the object OBJ in step S120. Next, the head-mounted device 100 controls the display unit 110 to display the object image OIMG of the object OBJ in step S130. After step S130, the operation method S100 returns to the operation of step S110. It is worth mentioning here that during use, the head-mounted device 100 can detect an object OBJ that poses a hazard to the user within a specific range PR and display the object image OIMG through the display unit 110. In this way, the safety performance of using the head-mounted device 100 can be improved. On the other hand, in step S110, when the first sensing device 120 does not detect an object OBJ that poses a hazard to the user U within the specific range PR, the first sensing device 120 continues to detect in step S110 whether there is an object OBJ that may pose a hazard to the user U within the specific range PR. In this embodiment, the first sensing device 120 is an infrared light detection device. The first sensing device 120 is, for example, a long-wave infrared (LWIR) detection device. The specific range PR may be a limb movement range centered on the user U (however, the present disclosure is not limited thereto). Therefore, the limb movement range of the user U is set as the specific range PR. The specific range PR can move as the user U moves. In this embodiment, the area of the specific range PR can be determined according to the detection distance of the first sensing device 120, or the user U can set the area range of the specific range PR in the head-mounted device 100 by himself / herself. In this embodiment, the head-mounted device 100 can analyze the infrared light data IRD corresponding to the infrared light image IRIMG captured by the first sensing device 120 for the infrared light image IRIMG. For example, the head-mounted device 100 further includes a processor 140. The processor 140 is coupled to the display unit 110, the first sensing device 120, and the second sensing device 130. The head-mounted device 100 can use the processor 140 to detect whether there is an object OBJ in the infrared light image IRIMG that may cause harm to the user U. The object OBJ may be a pet, a person, a heat source, or an obstacle, but the present disclosure is not limited thereto. The obstacle may be, for example, furniture or a wall. When it is determined that there is an object OBJ in the infrared light image IRIMG that causes harm to the user U, it means that there is an object OBJ in the specific range PR that causes harm to the user U. Therefore, the processor 140 notifies the second sensing device 130 to capture the object image OIMG of the object OBJ, and controls the display unit 110 to display the object image OIMG of the object OBJ. It should be noted that the head-mounted device 100 preferentially uses the first sensing device 120 to detect the environment around the user U. Therefore, the infrared light image IRIMG shows the contours of the objects around the user U, rather than showing the true visual appearance of the objects around the user U. Therefore, the environment around the user U will not be leaked. The privacy of the user U can be protected. The color interference of the ambient light can be reduced. In addition, in the case of dim environment, the head-mounted device 100 can also determine whether there is an object OBJ in the specific range PR that causes harm to the user. In this embodiment, the head-mounted device 100 can communicate with the external device ED either wired or wirelessly. The external device ED can be, for example, an electronic device with computing capabilities such as a server, a host computer, a desktop computer, a laptop computer, a tablet computer, or a smart phone. The external device ED receives the infrared light image IRIMG. The external device ED determines whether there is an object OBJ in the infrared light image IRIMG that may pose a hazard to the user U. When it is determined that there is an object OBJ in the infrared light image IRIMG that poses a hazard to the user U, the external device ED notifies the second sensing device 130 to capture the object image OIMG of the object OBJ, and controls the display unit 110 to display the object image OIMG of the object OBJ. In some embodiments, the external device ED includes a circuit similar to the function of the processor 140. The processor 140 is, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessors, digital signal processors (DSPs), programmable controllers, application specific integrated circuits (ASICs), programmable logic devices (PLDs), or other similar devices, or a combination of these devices, which can load and execute computer programs. The second sensing device 130 can be any form of visible light image capturing device (although the present disclosure is not limited thereto). The second sensing device 130 can be implemented, for example, by a charge coupled device (CCD) or an under-display image capturing device (although the present disclosure is not limited thereto). In some embodiments, the processor 140 can be disposed inside the head-mounted device 100 for the first sensing, or the processor 140 can be disposed on other electronic devices. The head-mounted device 100 can transmit data to the processor 140 for processing through data transmission. Therefore, the first sensing device 120 itself can determine whether there is an object OBJ in the infrared light image IRIMG that may pose a hazard to the user U without the need of an external device, notify the second sensing device 130 to capture the object image OIMG of the object OBJ, and control the display unit 110 to display the object image OIMG of the object OBJ. Please refer to FIG. 2 and FIG. 4 simultaneously. FIG. 4 is a schematic diagram of a processor according to an embodiment of the present disclosure. In this embodiment, the processor 140 includes an imaging circuit 141, an analysis circuit 142, and a notification circuit 143. The imaging circuit 141 receives the infrared light data IRD from the first sensing device 120 and renders the infrared light data IRD as an infrared light image IRIMG. The infrared light image IRIMG can show the contours and temperatures of heat sources around the user U. The analysis circuit 142 is coupled to the imaging circuit 141 and the notification circuit 143. The analysis circuit 142 receives the infrared light image IRIMG and analyzes the infrared light image IRIMG to determine whether there is an object OBJ that poses a hazard to the user U within a specific range PR. When there is an object OBJ that poses a hazard to the user U within the specific range PR, the analysis circuit 142 controls the notification circuit 143 to provide a notification signal SN. Accordingly, the second sensing device 130 captures an object image OIMG of the object OBJ in response to the notification signal SN. The display unit 110 displays the object image OIMG of the object OBJ. Please refer to FIG. 1, FIG. 2, and FIG. 5 simultaneously. FIG. 5 is a flowchart of an operation method according to another embodiment of the present disclosure. The operation method S200 is for the head-mounted device 100. The operation method S200 includes steps S210 to S270. The first sensing device 120 detects the surroundings of the user U in step S210. For example, in step S210, the first sensing device 120 detects the surroundings of the user U to provide the infrared light data IRD corresponding to the infrared light image IRIMG. In step S220, the processor 140 determines whether there is an object OBJ that may pose a hazard to the user U within the specific range PR. For example, in step S220, the processor 140 can use the infrared light data IRD to determine whether there is an object OBJ within the specific range PR. When the object OBJ is outside the specific range PR, the operation method S200 returns to the operation of step S210. In addition, when the object OBJ is outside the specific range PR, the processor 140 stops providing the notification signal SN. On the other hand, when the object OBJ is within the specific range PR, the processor 140 further determines the movement of the object OBJ within the specific range PR in step S230. In step S230, when the object OBJ within the specific range PR is moving away from the user U, the processor 140 determines that the object OBJ moving away from the user U will not pose a hazard to the user U. For example, the processor 140 determines that the contour of the infrared light image IRIMG within the specific range PR is rapidly shrinking. Therefore, the operation method S200 returns to the operation of step S210. In addition, when the object OBJ within the specific range PR moves away from the user U, the processor 140 stops providing the notification signal SN. In step S230, when the object OBJ within the specific range PR is approaching the user U, the processor 140 determines that the object OBJ approaching the user U will pose a hazard to the user U. For example, the processor 140 determines that the contour of the infrared light image IRIMG within the specific range PR is rapidly expanding. Therefore, the processor 140 provides the notification signal SN in step S240. Accordingly, the head-mounted device 100 alerts the user U based on the notification signal SN. For example, the display unit 110 can provide a warning light signal. When the moving speed of the object OBJ approaching the user U increases, the warning light signal becomes more prominent. For example, the blinking frequency or brightness of the warning light signal increases). In some embodiments, the head-mounted device 100 can provide a warning sound to alert the user U in step S240. When the moving speed of the object OBJ approaching the user U increases, the warning sound becomes more prominent. For example, the rhythm of the warning sound speeds up or the volume increases. In addition, in step S240, the second sensing device 130 captures the object image OIMG of the object OBJ in response to the notification signal SN. The display unit 110 displays the object image OIMG of the object OBJ. In step S250, the warning provided by the head-mounted device 100 is adjusted or cancelled. For example, when the user U learns through the display unit 110 that the object OBJ is approaching, the user U can move away from the object OBJ or move the object OBJ to a safe area. Accordingly, the user U cancels the warning through the head-mounted device 100. For example, when the user U learns through the display unit 110 that the approaching object OBJ will not pose a hazard, the user U adjusts the warning conditions through the head-mounted device 100. Therefore, the processor 140 can learn the infrared light image of the object OBJ that does not pose a hazard. For example, when the user U learns through the display unit 110 that the specific range PR needs to be adjusted, the user U adjusts the specific range PR through the head-mounted device 100. Accordingly, the warning conditions are also adjusted. After step S250, the operation method S200 returns to the operation of step S210. In step S230, when the object OBJ within the specific range PR does not approach or move away from the user U, it means that the object OBJ stays around the user U without moving. For example, the processor 140 determines that the size of the contour of the infrared light image IRIMG within the specific range PR has not changed. Therefore, the processor 140 provides a notification signal SN in step S260. The second sensing device 130 captures the object image OIMG of the object OBJ in response to the notification signal SN. The display unit 110 displays the object image OIMG of the object OBJ. In addition, the head-mounted device 100 alerts the user U based on the notification signal SN. In step S270, when the object OBJ continues to stay, the user U can selectively cancel the alert provided by the head-mounted device 100 for the object OBJ. After step S270, the operation method S200 returns to the operation of step S210. Please refer to FIGS. 1, 2, and 6 simultaneously. FIG. 6 is a flowchart of an operation method according to an embodiment of the present disclosure. The operation method S300 is for the head-mounted device 100. The operation method S300 includes steps S310 to S350. The first sensing device 120 detects the surroundings of the user U in step S310. For example, in step S310, the first sensing device 120 detects the surroundings of the user U, for example, to provide infrared light data IRD corresponding to the infrared light image IRIMG. In step S320, the processor 140 determines whether there is a high-temperature area around the user U. The high-temperature area is, for example, a heat source having a temperature greater than a predetermined temperature. In step S320, the processor 140 can use the infrared light data IRD to determine whether there is a high-temperature area around the user U. When there is no high-temperature area around the user U, the operation method S300 returns to the operation of step S310. On the other hand, when there is a high-temperature area around the user U, the processor 140 further determines the change of the high-temperature area in step S330. In step S330, when the high-temperature area does not change over time, it means that the high-temperature area may be a fixed heat source (such as a heater or an electric lamp). Therefore, the processor 140 does not provide a notification signal SN. The operation method S300 returns to the operation of step S310. In step S330, when the area of the high-temperature area increases over time, it means that the heat source is gradually approaching the user U or the heat source is expanding. Therefore, the processor 140 provides a notification signal SN in step S340. Therefore, the head-mounted device 100 alerts the user U based on the notification signal SN. The second sensing device 130 captures the surrounding image in response to the notification signal SN. The display unit 110 displays the surrounding image. In addition, when the temperature in the high-temperature area rises rapidly, the processor 140 also provides a notification signal SN in step S340. The head-mounted device 100 alerts the user U. The second sensing device 130 captures the surrounding image. The display unit 110 displays the surrounding image. Please refer to FIG. 1 and FIG. 7 simultaneously.

Taking this embodiment as an example, the first sensor 220_1 is disposed on the front surface of the eyepatch 260. The first sensor 220_2 is disposed on the headband 250. When the user U wears the head-mounted device 200, the first sensor 220_1 detects forward towards the user U. The first sensor 220_2 detects backward towards the user U. The second sensors 230_1 and 230_2 are disposed on the front surface of the eyepatch 260.

The visible light images captured by the second sensors 230_1 and 230_2 contribute to generating a 3D stereoscopic image. Please refer to FIG. 9. FIG. 9 is a schematic diagram of the display unit and the first sensor according to an embodiment of the present disclosure. In this embodiment, FIG. 9 shows the display unit 210 and the first sensor 220_1. In this embodiment, the display unit 210 includes a plurality of display pixels PD and a substrate SB. The plurality of display pixels PD are disposed on the substrate SB. The first sensor 220_1 includes a plurality of sensing pixels PS. The plurality of sensing pixels PS can be arranged in an array on the substrate SB. In other words, the first sensor 220_1 and the plurality of display pixels PD of the display unit 210 are disposed on the same substrate SB. In this embodiment, the display unit 210 is a transparent display panel. The substrate SB may be a glass substrate (although the present disclosure is not limited thereto). In some embodiments, the substrate SB may be a flexible substrate. In this embodiment, the layout positions of the plurality of display pixels PD are substantially the same as the layout positions of the plurality of sensing pixels PS. In addition, the size positions of the plurality of display pixels PD are substantially the same as the sizes of the plurality of sensing pixels PS. Therefore, the corresponding regions between the plurality of display pixels PD and between the plurality of sensing pixels PS may have transparency. In this embodiment, the transparency of the display unit 210 is adjusted so that a user can view the external environment through the display unit 210. In this way, the user can view the external environment without removing the head-mounted device. In this embodiment, the plurality of sensing pixels PS are each a micro electro mechanical (MEM) structure. The plurality of sensing pixels PS may each include foot pads PAD1, PAD2, a resistor structure CN, and a sensing structure SL. The resistor structure CN is electrically connected to the foot pads PAD1 and PAD2. The sensing structure SL partially covers and contacts the resistor structure CN. The sensing structure SL can change the impedance value of the resistor structure CN according to infrared light. The sensing structure SL may be a heat absorption structure, a metal, or a material that easily absorbs infrared light bands. The first sensor 220_1 provides infrared light data corresponding to the infrared light image (the infrared light data IRD of the infrared light image IRIMG shown in FIG. 2) according to the change in the impedance value. The first sensor 220_1 can receive, for example, the signal current generated by the sensing pixel PS due to impedance change through the foot pads PAD1 and PAD2. Please refer to FIG. 9 and FIG. 10 simultaneously. FIG. 10 is a schematic diagram of a display unit and a first sensor according to an embodiment of the present disclosure. In this embodiment, FIG. 10 shows the display unit 210 and the first sensor 220_1. The first sensor 220_1 is attached to the display unit 210. For example, the plurality of display pixels PD are disposed on a first side of the substrate SB. The first sensor 220_1 is attached to a second side of the substrate SB. The second side is opposite to the first side. The positions of the plurality of display pixels PD correspond to the positions of the plurality of sensing pixels PS. Therefore, the region between the plurality of display pixels PD has transparency. Please refer to FIG. 7 and FIG. 11 simultaneously. FIG. 11 is a schematic diagram of a display unit and a mask according to an embodiment of the present disclosure. In this embodiment, the head-mounted device 200 further includes a mask 270. The display unit 210 is a transparent display panel. The mask 270 is operated to cover the display unit 210. Therefore, the mask 270 can block the light L from the external environment. The immersion experience of the head-mounted device 200 can be enhanced. On the other hand, the mask 270 is moved so as not to cover the display unit 210. The light L from the external environment penetrates the display unit 210. Therefore, the user can view the external environment through the display unit 210. Please refer to FIG. 9 and FIG. 12A simultaneously. FIG. 12A is a schematic diagram of a display unit, a first sensor, and a mask according to an embodiment of the present disclosure. In this embodiment, the head-mounted device 200 further includes a mask 270. The display unit 210 is a transparent display panel. The first sensor 220_1 is attached to the display unit 210. There may be transparency between the plurality of display pixels PD and the plurality of sensing pixels PS. The light L from the external environment can penetrate the first sensor 220_1 and the display unit 210. In this embodiment, the mask 270 is operated to cover the display unit 210 and the first sensor 220_1, thereby blocking the light L from the external environment. Therefore, the immersion experience of the head-mounted device 200 can be enhanced. On the other hand, the mask 270 is moved so as not to cover the display unit 210. The light L from the external environment penetrates the display unit 210 and the first sensor 220_1. Therefore, the user can view the external environment through the display unit 210 and the first sensor 220_1. Please refer to FIG. 9 and FIG. 12B simultaneously. FIG. 12B is a schematic diagram of a display unit, a first sensor, and a mask according to an embodiment of the present disclosure. In this embodiment, the display unit 210 is a transparent display panel. The first sensor 220_1 is not attached to the display unit 210. However, the positions of the plurality of display pixels PD correspond to the positions of the plurality of sensing pixels PS. Therefore, the light L from the external environment can still penetrate the first sensor 220_1 and the display unit 210. When the mask 270 is operated to cover the display unit 210, the mask 270 is located between the first sensor 220_1 and the display unit 210. The mask 270 can block the light L from the external environment. The immersion experience of the head-mounted device 200 can be enhanced. On the other hand, the mask 270 is moved so as not to cover the display unit 210. The light L from the external environment penetrates the display unit 210. Therefore, the user can view the external environment through the display unit 210 and the first sensor 220_1. In summary, the first sensing device detects whether there is an object that poses a hazard to the user within a specific range. When an object that poses a hazard to the user is detected within the specific range, the display unit displays the object image of the object. In this way, the head-mounted device can know that there is an object that poses a hazard to the user within the specific range and display the object image of the object through the display unit. The safety performance of the head-mounted device can be improved. In addition, in one embodiment, the first sensing device is an infrared light detection device. The head-mounted device preferentially uses the first sensing device to detect the environment around the user. The infrared light image shows the outline of the objects around the user, rather than the true visual appearance of the objects around the user. Therefore, the environment around the user will not be leaked. The privacy of the user can be protected. In addition, in a dim environment, the head-mounted device can also determine whether there is an object that poses a hazard to the user within the specific range.
