The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and 2, fig. 1 is a schematic flow chart of a first embodiment of the remote control method of the present invention; fig. 2 is a schematic structural diagram of the handheld terminal and the display device in fig. 1. As shown in fig. 2, the handheld terminal 21 and the display device 22 establish a wireless connection, for example, the handheld terminal 21 and the display device 22 establish a wireless connection through WiFi or bluetooth. The handheld terminal 21 includes a first communication module 210 and a first processing module 211 connected to the first communication module 210. The display device 22 includes a second communication module 220 and a second processing module 221 connected to the second communication module 220, wherein the first communication module 210 of the handheld terminal 21 is connected to the second communication module 220 of the display device 22 to implement data interaction.
The remote control method of the present embodiment is applied to the handheld terminal 21 having the floating screen, and includes:
s11: the handheld terminal 21 transmits the effective size of the floating screen to the display device 22.
S12: the handheld terminal 21 displays a joystick icon on the floating screen.
S13: the handheld terminal 21 acquires floating information generated by a touch body performing a floating motion on a floating screen or touch information generated by a touch motion on the floating screen.
S14: the handheld terminal 21 transmits the hover information or the touch information to the display device 22 in real time.
The display device 22 is selected from, but not limited to, a smart tv, a computer, etc. The handheld terminal 21 is an electronic device having a floating screen, and is selected from, but not limited to, a mobile phone or a PDA (Personal Digital Assistant). The floating screen is a screen supporting a floating touch technology, and is different from a common touch screen, the common touch screen only has mutual capacitance and is used for realizing multi-point touch detection, but the electric field of the mutual capacitance sensor is very small, so that the signal intensity is very low, and very weak signals cannot be sensed. The floating screen of the embodiment at least comprises two capacitive sensors, namely at least a mutual capacitance sensor and a self-capacitance sensor, the self-capacitance can generate a signal stronger than the mutual capacitance, and the range of the detection distance of the floating screen can be up to 20mm by detecting a farther finger.
The embodiment takes a mobile phone to remotely control the smart television as an example for explanation.
Referring to fig. 3, the mobile phone 31 and the smart tv 32 of the present embodiment establish a peer-to-peer connection through bluetooth, the mobile phone 31 has a floating screen 310, and the smart tv 32 has a common display screen 320.
First, the mobile phone 31 is switched to the remote control mode, and a gamepad icon is displayed on the floating screen 310 of the mobile phone 31 to guide a user to perform a floating action or a touch action on the floating screen 310 according to the gamepad icon.
Referring to fig. 3 to 5 together, the mobile phone 31 sends the effective size of the floating screen 310 to the smart tv 32, so that the smart tv 32 defines an operation area 321 with the same aspect ratio as the effective size on the display screen 320 of the mobile phone 31 according to the effective size of the floating screen 310. Here, the mapping method for the display screen of the control end and the screen of the controlled end adopts a method with equal length-to-width ratio, which has the advantages that the image proportions displayed on the two screens are consistent, the image content is not deformed, but the content on the display screen of the controlled end is not displayed or if the content is displayed, the redundant content cannot be operated and remotely controlled through the control end; therefore, alternatively, a full mapping method may be adopted, in which the display screens of the control terminal and the controlled terminal are all aligned in the maximum sizeIt should be understood that the method is a method with different length-width ratios, so that all the contents on the display screen of the controlled end can be remotely controlled through the control end. The embodiment preferably uses an equal length-to-width ratio method for mapping, for example, the mobile phone 31 sends the length L1 and the width W1 of the floating screen 310 to the smart tv 32, where the ratio L1/W1 of the length L1 and the width W1 of the floating screen is a, so that the smart tv 32 divides the operation area 321 having the same ratio as the length L1 and the width W1 of the floating screen on the self display screen 320 according to the ratio a of the length L1 and the width W1 of the floating screen, where the length of the operation area 321 is L2, the width is W2, and the length L2/W2 is a. In this embodiment, the length L2 and the width W2 of the operation region 321 are c times the length L1 and the width W1 of the suspension screen, respectively, i.e., L2 ═ c × L1, W2 ═ c × W1,
optionally, a gamepad icon may be even displayed on the display currently displayed on the mobile phone 31 to guide the user to perform operations, where two circles shown in fig. 4 are gamepad icons to guide the user to select the circle for sliding or selecting operations.
The mobile phone 31 acquires hover information generated by a touch object performing a hover action on the hover screen 310 or touch information generated by a touch action on the hover screen 310, where the touch object refers to a finger of a user. The floating information includes coordinates of the user's finger on the floating screen 310 and a distance from the floating screen 310, and the touch information includes coordinates of the user's finger on the floating screen 310.
The hover action of the present embodiment is a hover action performed by two touch objects on the hover screen 310, and the touch action is a touch action performed by two touch objects on the hover screen 310, that is, the present invention supports the user to operate on the hover screen 310 by using both fingers of the user. For convenience of explanation, the left and right fingers of the user are used as touch objects. The floating information includes two coordinates of the left and right fingers of the user on the floating screen 310 and two distances from the floating screen 310, respectively, and the touch information includes two coordinates of the left and right fingers of the user on the floating screen 310, respectively.
In the present embodiment, when the fingers of the two hands of the user perform the floating operation on the floating screen 310, as shown in fig. 6, a coordinate system X-Y-Z is established by using the floating screen 310, wherein the coordinate system X-Y-Z uses one corner of the floating screen 310 as a coordinate origin, for example, uses a vertex at a lower left corner of the floating screen 310 as the coordinate origin, uses a length direction of the floating screen 310 as an X axis, uses a width direction as a Y axis, and the Z axis is perpendicular to the X axis and the Y axis. The floating screen 310 obtains two corresponding coordinates (x11, y11) and (x12, y12) of the left and right fingers A, B hovering over the floating screen 310, and the floating screen 310 can obtain the distances between the two fingers A, B and itself as b1 and b2 respectively. When the user's finger C, D performs a touch operation on the floating screen 310, the floating screen 310 detects a position where the finger touches the floating screen 310, thereby obtaining two coordinates (x21, y21) and (x22, y22) on the floating screen 310 where the finger C, D corresponds.
The mobile phone 31 sends the floating information or the touch information to the smart television 32 in real time, so that the smart television 32 draws and displays a first indication icon in the operation area 321 according to the floating information, the smart television 32 draws and displays a second indication icon in the operation area 321 according to the touch information, and the smart television 32 selects an object specified by the second indication icon when acquiring the touch information.
In the present embodiment, the smart tv 32 multiplies the abscissa and the ordinate of the coordinates (x11, y11) and (x12, y12) in the floating information by the same multiple, respectively, to generate the corresponding first coordinate. For example, the X-axis and Y-axis values of the coordinates (X11, Y11) and (X12, Y12) are multiplied by the multiple c, respectively, so as to obtain corresponding first coordinates (X11, Y11) and (X12, Y12) on the operation area 321 of the smart tv 32, as shown in fig. 7. Wherein, X11 ═ c × X11, Y11 ═ c × Y11, X12 ═ c × 12, and Y12 ═ c × Y12. Similarly, the smart tv 32 multiplies the abscissa and the ordinate of the coordinates (X21, Y21) and (X22, Y22) in the touch information by the same multiple c to obtain corresponding second coordinates (X21, Y21) and (X22, Y22). Thereby, the smart tv 32 draws and displays the first indication icon in the operation area 321 according to the first coordinates (X11, Y11) and (X12, Y12), and draws and displays the second indication icon in the operation area 321 according to the second coordinates (X21, Y21) and (X22, Y22). And, since the floating information further includes distances b1 and b2 between the fingers of both hands of the user and the floating screen, the smart tv 32 draws 321 the first indication icon in the operation area according to the first coordinates (X11, Y11) and (X12, Y12) and according to the distances b1 and b2 between the fingers and the floating screen 310, so that the display size of the first indication icon is inversely proportional to the distance in the floating information, that is, the larger the distance between the fingers and the floating screen 310, the smaller the first indication icon. In addition, when the first indicator icon is displayed in the operation area 321 of the smart television 32, the corresponding object in the smart television 32 is not selected, so that the user can perform a mouse-like tracking operation on the smart television 32 by performing a floating operation on the mobile phone 31. In addition, the smart tv 32 draws and displays a second indication icon in the operation area 321 according to the second coordinates (X21, Y21) and (X22, Y22), and the smart tv 32 selects an object pointed by the second indication icon, so that the user can perform a mouse-like click selection operation on the smart tv 32 by performing a touch operation on the cell phone 31. Here, fig. 4 shows a joystick guide icon, and fig. 5 shows a smart phone 32 displaying an indication icon at a position corresponding to the operation area 321 based on hover information or touch information transmitted from the cellular phone 31.
The first indication icon and the second indication icon can adopt the same or different icon shapes. In other embodiments, the first indicator icon may also adjust the shade of the icon color based on the distance in the hover message, e.g., the darker the color of the first indicator icon as the distance between the user's finger and the hover screen 310 is smaller. When the user's finger touches the floating screen 310, that is, the distance between the user's finger and the floating screen 310 is 0, a second indication icon is displayed on the floating screen 310, the second indication icon can be formed by adjusting the color of the first indication icon to the deepest color and displaying a floating ripple on the first indication icon to remind the user that the current finger has touched the floating screen 310, and an object pointed by the second indication icon is selected.
Therefore, in the embodiment, the wireless connection is established between the mobile phone 31 and the smart television 32, the smart television 32 is remotely controlled by using the mobile phone 31, the mobile phone 31 supports two-point operation and suspension operation, the position of the finger on the smart television 32 is synchronously displayed by performing the suspension operation on the mobile phone 31 without performing action response so as to avoid mistaken clicking, the corresponding object on the smart television 32 is selected by performing the touch action on the mobile phone 31, and the mobile phone 31 supports two-point operation, so that the user can remotely control the smart television 32 by using two hands by controlling the mobile phone 31 with the two hands, and the user experience is greatly improved.
In other embodiments, the angle between the indication icon and the rectangular plane coordinate system of the floating screen 310 may be determined to identify the floating operation or the touch operation performed by the finger of the user on the floating screen 310, where the rectangular plane coordinate system is formed by taking the vertex at the lower left corner of the floating screen 310 as the origin of coordinates, the length direction of the floating screen 310 as the X axis, and the width direction as the Y axis. When the finger of the user performs the hover operation on the hover screen 310, an included angle between the indication icon and the plane orthogonal coordinate system of the hover screen 310 is α, and when the finger of the user performs the touch operation on the hover screen 310, an included angle between the indication icon and the coordinate system of the hover screen 310 is β, where α > β, as shown in fig. 8. It is thereby possible to determine whether the user's finger performs a touch operation or a hover operation on the hover screen 310.
In other embodiments, the indication icon may also vary in size according to the response amount of the user's finger approaching or touching the floating screen 310, for example, when the user's finger touches the floating screen 310, the response amount is the largest, the indication icon displays the largest shape, when the user's finger is floating on the floating screen 310, the response amount is inversely proportional to the distance between the finger and the floating screen, that is, the smaller the distance between the finger and the floating screen, the larger the response amount, and thus the variation of the indication icon may be controlled according to the response amount obtained by the floating screen 310, as shown in fig. 9. Therefore, the object can be tracked or selected by judging the floating operation or touch operation of the finger of the user on the mobile phone 31 according to the size of the indication icon.
Referring to fig. 10, fig. 10 is a flowchart illustrating a remote control method according to a second embodiment of the present invention. Referring to fig. 10 in conjunction with fig. 2 to 5, the remote control method of the present embodiment is applied to the display device 22, and the display device 22 is wirelessly connected to the handheld terminal 21 having the suspension screen. The remote control method comprises the following steps:
