Accordingly, the directional terminology used is intended to be in the nature of words of description rather than of limitation.
Fig. 1 is a schematic view of a touch projection system according to an embodiment of the invention. Referring to fig. 1, the touch projection system 10 includes a touch projection screen 110 and a projection device 120. The components and the arrangement of the touch projection system 10 in fig. 1 are described with reference to fig. 2.
In an embodiment, the touch screen 110 can be used to display the projection image PI and detect a touch operation applied to the touch screen 110. In other words, the touch screen 110 has a touch display surface, and can display the projection image PI according to the image beam projected by the projection device 120, and can detect the touch operation of the user on the touch display surface. The touch screen 110 includes, for example, a projected capacitive touch screen, an electromagnetic touch screen, a resistive touch screen, or other suitable touch screens, which is not limited in the present invention.
The projection device 120 is electrically connected to the touch screen 110, and the projection device 120 can project the projection image PI on the touch screen 110. In some embodiments, the projection device 120 may include a Liquid Crystal Projector (LCP), a Digital Light Processing (DLP) Projector, or a Liquid Crystal On Silicon (LCOS) projection display device, among others. In this embodiment, the projection device 120 may include a storage device 121 and a processor 122, and may also include a light source module, an optical-mechanical module, a light valve, a lens module, and related optical and circuit control components, which are not limited in the present invention.
In an embodiment, the storage device 121 may include any type of fixed or removable Random Access Memory (RAM), Read-Only Memory (ROM), Flash Memory (Flash Memory), a hard disk, or other similar devices or combinations thereof, for recording a plurality of modules executable by the processor 122, and the modules may load the processor 122 to perform the touch projection method of the embodiment of the invention, which is not limited in this respect.
In one embodiment, the processor 122 may include a Field Programmable Gate Array (FPGA), a Programmable Logic Device (PLD), an Application Specific Integrated Circuit (ASIC), other similar devices, or a combination thereof. The Processor may also include a Central Processing Unit (CPU) or other programmable general purpose or special purpose Microprocessor (Microprocessor), Digital Signal Processor (DSP), Graphics Processing Unit (GPU), other similar devices, or a combination thereof, as the present invention is not limited in this respect. The processor 122 may be coupled to the storage device 121 to access and execute the module instructions recorded in the storage device 121. The processor 122 may be further coupled to the touch screen 110, so as to execute the touch projection method according to the embodiment of the invention according to the touch signal fed back by the touch screen 110.
Fig. 2 is a flowchart of a touch projection method according to an embodiment of the invention, and the method flow of fig. 2 can be implemented by the touch projection system 10 of fig. 1. Referring to fig. 1 and fig. 2, the steps of the touch projection method of the present embodiment are described below with reference to the touch projection system 10 in fig. 1.
In the embodiment shown in fig. 2, in step S201, the projection device 120 projects the projection image PI onto the touch screen 110. The projection device 120 projects the image beam toward the touch screen 110, so that the projection image PI is displayed on the touch screen 110.
In this embodiment, in step S202, the touch screen 110 detects a touch operation applied to the touch screen 110. In some embodiments, the touch screen 110 can include at least one touch sensing device, which can be arranged in an array and can be used to detect a touch operation. For example, the touch sensing device may include, but is not limited to, a capacitive touch sensing device, a surface acoustic wave touch sensing device, an electromagnetic touch sensing device, a near field imaging touch sensing device, and the like. When the touch sensing component is triggered, a sensing value is generated according to touch operation, wherein the touch operation may include at least one parameter selected from the following parameters: contact point location, contact point number, contact point spacing, contact duration, and combinations thereof. The invention is not limited in this regard.
In this embodiment, in step S203, the projection device 120 determines whether the touch operation is consistent with a specific gesture. In some embodiments, the projection device 120 may determine whether the touch operation is consistent with a specific gesture according to the at least one parameter of the touch operation, where the specific gesture includes a static gesture and a dynamic gesture. For example, the projection device 120 may determine that the touch operation is a click operation or a long press operation according to the contact duration. Alternatively, the projection device 120 may determine whether the touch operation is a single-touch operation or a multi-touch operation according to the number of the touch points. Alternatively, the projection apparatus 120 may determine whether the touch operation is to click the display object in the projection image PI according to the number of the contact points and the positions of the contact points.
In the embodiment of the present invention, the specific gesture includes, for example, two fingers pressing the touch screen 110 for more than 1 second. Correspondingly, the projection device 120 can determine whether the touch operation of the user is the long press of which the duration exceeds 1 second according to the number of the contact points and the distance between the contact points, and determine whether the touch operation of the user is the long press of which the duration exceeds 1 second, so as to determine whether the touch operation detected by the touch projection screen 110 meets a specific gesture. In the embodiment of the present invention, the specific gesture may also include five fingers touching and clicking the touch screen 110. Correspondingly, the projection device 120 can determine whether the touch operation of the user is that five fingers contact the touch screen 110 according to the number of the contact points and the distance between the contact points, so as to determine whether the touch operation detected by the touch screen 110 meets a specific gesture. However, the specific gesture can be designed according to the actual requirement, and can also be set by the user, which is not limited in the present invention.
In the embodiment of the present invention, in step S204, in response to the touch operation conforming to the specific gesture, the projection device 120 executes the projection control function corresponding to the specific gesture. That is, the user can control the projection device 120 to perform the corresponding projection control function through a specific gesture. In the embodiment of the present invention, the projection control function corresponding to the specific gesture includes, for example, a screenshot function, a control menu display function, a system mode switching function, or an execution tool application function, which is not limited in this respect. Further, a particular gesture may include more than one number of gestures. For example, when the touch operation is determined to be in accordance with a first gesture of the specific gestures, the projection device 120 may perform a first projection control function. When the touch operation is determined to be in accordance with a second gesture of the specific gestures, the projection device 120 may perform a second projection control function different from the first projection control function.
It should be noted that, in the embodiment of the present invention, the projection device 120 may determine whether to execute the projection control function according to whether the touch operation is in accordance with the specific gesture. Since the user can touch any position of the touch screen 110 to perform the touch operation, the user does not need to move the position to click the display object disposed at the fixed position on the touch screen 110 to control the projection device 120 to perform a specific function. The invention can greatly improve the operation convenience and the fluency of a user during the use of the touch projection system. In addition, during the execution of the application program by the projection device 120, the projection device 120 may also execute an additional projection control function in response to the touch operation conforming to the specific gesture. In other words, if the projection apparatus 120 determines that the touch operation matches the specific gesture, the projection apparatus 120 may perform an additional projection control function regardless of whether the application is executed by the projection apparatus 120. Specifically, when the projection device 120 executes the application program, the projection screen PI displayed by the touch screen 110 is an application screen. When the touch screen 110 detects a touch operation and the projection device 120 determines that the touch operation matches a specific gesture, the projection device 120 may execute a projection control function corresponding to the specific gesture while displaying an application screen.
3A-3C are schematic diagrams of a situation in which a control menu is operated by a specific gesture according to an embodiment of the present invention. In the present embodiment, the specific gesture includes a first gesture, wherein the first gesture is that two fingers contact the touch screen 110 for more than 1 second at the same time, but the invention is not limited thereto. Referring to fig. 3A, when the touch screen 110 detects a touch operation G1 applied to the touch screen 110 by a user, the projection device 120 (shown in fig. 1) determines that the touch operation G1 matches the first gesture according to the number of contact points of the touch operation G1 being equal to 2 and the duration of the contact time exceeding 1 second. Referring to fig. 3B, in response to the touch operation G1 conforming to the first gesture, the display control menu M1 corresponding to the projection device 120 is displayed for further operation by the user. In the present embodiment, the control menu M1 can be overlappingly displayed on the projection screen PI, and the control menu M1 can include a plurality of control options (e.g., the options "menu" (menu), option "C", option "APP" and option "S" shown in fig. 3B). For example, the control options may respectively correspond to an OSD setting menu or an application menu of the projection apparatus 120.
It should be noted that the position of the control menu M1 on the touch screen 110 corresponds to the position of the touch point of the touch operation G1. Specifically, the position of the control menu M1 on the projection screen PI can be determined based on the contact point position of the touch operation G1, so as to ensure that the user can select and operate the control menu M1 nearby. In other embodiments, the projection device 120 may also determine the touchable range according to the contact point position of the touch operation G1, and the touchable range may be defined as a range separated from the contact point position of the touch operation G1 by a predetermined distance. And the control menu M1 can be displayed within the accessible range to ensure that the display position of the control menu M1 can be easily reached by the user.
Referring to fig. 3C, after the control menu M1 is displayed, the touch screen 110 can detect another touch operation 2 applied within the range of the control menu M1. In response to the touch screen 110 detecting another touch operation G2 within the range of the control menu M1, the projection device 120 can adjust the setting parameters of the projection device 120. For example, the setting parameters may include, but are not limited to, volume, projection brightness, projection resolution, and frame keystone correction parameters. In the present embodiment, another touch operation G2 can be the user clicking on the option "menu" (menu) within the range of the control menu M1, in which case the touch screen 110 can display another sub-menu M2. In other embodiments, the touch operation G2 may be a user clicking on the option "S" within the control menu M1, in which case the user may set or adjust the relevant setting parameters of the projection device 120. In another embodiment, the control menu M1 may also directly provide a parameter setting interface, for example, the control menu M1 may include options of volume, projection brightness, projection resolution, and keystone correction, so as to provide more convenient parameter setting for the user. Referring to fig. 3A to 3C, the user can call up the control menu M1 with a specific gesture without moving, and further perform a projector setting or operation by means of the control menu M1.
Fig. 4A to 4C are schematic diagrams illustrating a situation in which a control menu is operated by a specific gesture during execution of an application according to an embodiment of the present invention. In the embodiment, the projection device 120 executes a projection control function corresponding to a specific gesture during the execution of the application program. For convenience of illustration, the specific gesture is similar to the implementation of fig. 3 to 3C, for example, a first gesture in which two fingers press the touch screen 110 for more than 1 second at the same time, but the invention is not limited thereto.
Referring to fig. 4A, during the application program being executed by the projection device 120, the touch screen 110 displays an application screen AF1, and in the embodiment, the application screen AF1 can be superimposed on the projection screen PI. The method for controlling or operating the touch projection system by the user through the touch operation G3 is similar to the embodiment shown in fig. 3A to 3C, and is not repeated herein. Referring to FIG. 4B, the control menu M1 is overlapped on the application frame AF 1. In other words, during the execution of the application program by the projection device 120, the user can call the control menu M1 according to the specific gesture without closing the application program. Similarly, the position of the control menu M1 on the application screen AF1 can be determined based on the contact point position of the touch operation G3, so as to ensure that the user can click and operate the control menu M nearby.
FIGS. 5A and 5B are schematic diagrams of a scenario of performing a screenshot with a specific gesture according to an embodiment of the present invention. In the present embodiment, the specific gesture includes a second gesture, wherein the second gesture is a simultaneous click of the touch screen 110 by five fingers, but the invention is not limited thereto. Referring to fig. 5A, when the touch screen 110 detects a touch operation G4 applied to the touch screen 110 by a user, the projection device 120 (shown in fig. 1) determines that the touch operation G4 matches the second gesture according to the number of contact points of the touch operation G4 being equal to 5 and the distance between the contact points of the touch operation G4 matching the one-hand touch condition. Referring to fig. 5B, in response to the touch operation G4 conforming to the second gesture, the projection device 120 executes a corresponding screenshot (Screen Shot) function to capture and store the currently displayed projection image PI. In this embodiment, the projection device 120 can store the captured projection image PI in the storage device 121 or other external storage devices. After completing the screenshot, the projection device 120 may display a notification M3 to inform the user that the screenshot function was performed. For example, the notification M3 may include the contents of "captured picture" or "stored captured picture". In another embodiment, the projection image PI may flash one or more times when capturing the projection image PI to notify the user of the execution of the screenshot function. Similarly, in an embodiment, during the application program executed by the projection device 120, if the touch screen 110 detects the touch operation G4 and the projection device 120 determines that the touch operation G4 matches the second gesture, the projection device 120 may also retrieve and store the projection image P including the application image.
FIGS. 6A and 6B are schematic diagrams illustrating a system mode switching by a specific gesture according to an embodiment of the present invention. In the present embodiment, the specific gesture includes a third gesture, wherein the third gesture is a continuous touch of two fingers on the touch screen 110, but the invention is not limited thereto. Referring to fig. 6A, when the touch screen 110 detects a touch operation G5 applied to the touch screen 110 by a user, the projection device 120 (shown in fig. 1) determines that the touch operation G5 satisfies the third gesture according to the condition that the number of contact points of the touch operation G5 is equal to 2 and the contact time interval of the touch operation G5 satisfies the continuous tapping condition. Referring to fig. 6B, in response to the touch operation G5 meeting the third gesture, the projection device 120 performs system mode switching to enter the system sleep mode. In this embodiment, the projection device 120 may display a sleep confirmation notification M4 to allow the user to confirm whether to enter the system sleep mode again. For example, the sleep confirmation notification M4 may include a plurality of control options (e.g., option "Y" and option "N" shown in fig. 6B), and when the user clicks "Y", the system enters the system sleep mode. In another embodiment, in response to the touch operation G5 conforming to the third gesture, the projection device 120 may directly enter the system sleep mode.
Fig. 7A and 7B are schematic views illustrating a situation in which a screen brush program is executed by a specific gesture according to an embodiment of the present invention. In the present embodiment, the specific gesture includes a fourth gesture, wherein the fourth gesture is a long press of the touch screen 110 for more than 5 seconds by a single finger, but the invention is not limited thereto. Referring to fig. 7A, when the touch screen 110 detects a touch operation G6 applied to the touch screen 110 by a user, the projection device 120 (shown in fig. 1) determines that the touch operation G6 matches the fourth gesture according to the number of contact points of the touch operation G6 being equal to 1 and the duration of contact of the touch operation G5 exceeding 5 seconds. Referring to fig. 7B, in response to the touch operation G6 corresponding to the fourth gesture, the projection device 120 executes a screen brush program to display a brush function menu M5 on the touch screen 110. In this embodiment, the brush function menu M5 may be displayed on the projection screen PI in an overlapping manner, and the brush function menu M5 may include a plurality of drawing options (e.g., the option "color" and the option "thickness" shown in fig. 7B). In other embodiments, the brush function menu M5 may also include a palette option. In this embodiment, the position of the brush function menu M5 on the touch screen 110 corresponds to the contact position of the touch operation G6. The user can then set the color of the line drawn by the brush through the brush function menu M5. Referring to fig. 7C, according to the detected moving track of the user's finger F1, the projection apparatus 120 can display a corresponding brush pen trace T1 on the projection screen PI.
In the above embodiments, when the touch screen detects a touch operation applied to the touch screen 110 by a user, and the projection device 120 (shown in fig. 1) determines that the touch operation does not conform to a specific gesture, the projection device 120 may determine a specific gesture most similar to the touch operation according to a parameter related to the touch operation, for example, the specific gesture is most similar to the fourth gesture. In this case, the projecting device 120 may execute a screen-brush program corresponding to the fourth gesture. Alternatively, in other cases, the projection device 120 may display a confirmation menu on the touch screen 110 to further confirm that the touch operation corresponds to the fourth gesture.
In summary, in the embodiment of the invention, the projection apparatus determines whether the touch operation of the user conforms to the specific gesture according to the contact information detected by the touch projection screen, so as to further start the corresponding function of the projection apparatus. In this way, since the user can contact any position of the touch projection screen to perform the touch operation, the user does not need to move the position to click the display object disposed at the fixed position on the touch projection screen to control the projection device to perform the specific function, and the projection device can perform additional projection control functions regardless of whether the application program is executed. Therefore, in the touch projection system and method of the invention, by means of the touch projection screen, a user can use a plurality of different gestures to activate a plurality of functions of the projection device, so that the user can operate the touch projection system more intuitively, simply and conveniently or more frequently, thereby improving the convenience and variability of the touch projection system in use.
