## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority to Chinese Patent Application No. CN201210280611.7, filed in the State Intellectual Property Office of P.R. China, on Aug. 8, 2012, which is hereby incorporated herein in its entirety by reference.
FIELD OF THE INVENTION
The present invention relates generally to smart televisions, and more particularly to method, apparatus and remote control for annular-selector based television interaction.
BACKGROUND OF THE INVENTION
As smart phones, tablet computers, the Internet and other technologies develop, the concept of “smart” gradually enters the field of televisions. Currently, the televisions are undergoing changes from backward operations to forward operations. The conventional televisions are easy to learn and use, but provide only a few simple services. A smart television is very rich in service contents, but the interaction method is complicated, and is difficult for users to operate. How to enable users to easily operate becomes a key issue that requires television manufacturers to put efforts for improvements.
A conventional interaction method that operates a smart television has much inconvenience and complexity. For example, the Internet and smart television based online movies, application stores and other functions may provide a user with more choices on a same television interface, so that when using a conventional remote control to select a desired content therein, the user needs to press buttons such as Up, Down, Left, Right, OK, and Return, which is very cumbersome. As functions increase, a single interface cannot display all contents, so that back-and-forth jumping between different levels and pages is required. For example, when a user needs to view a video, he/she needs to enter into a home page, online movie, variety, and then performs selection, and the number of levels of the path is large. As the technologies develop, a television interface can provide a user with more and more interaction experiences, but a conventional operation method is unable to make an action of the user match a corresponding effect presented by the television, thereby limiting diversity of television interaction experiences. For example, when a rotary operating animation appears on the television, the user performs control through Left and Right buttons, thereby providing the user with the feeling that does not match.
Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.

The description will be made as to the embodiments of the present disclosure in conjunction with the accompanying drawings in FIGS. 1-8. It should be understood that specific embodiments described herein are merely used for explaining the present invention, but are not intended to limit the present invention. In accordance with the purposes of this disclosure, as embodied and broadly described herein, this invention, in one aspect, relates to method, apparatus and remote control for annular-selector based television interaction.
Referring to FIG. 1, a flow chart of a method for annular-selector based television interaction is shown according to a first embodiment of the present invention. In this exemplary embodiment, the method includes the following steps.
At step S101: rotation information of an annular selector sent by a remote control is received by an interaction apparatus of a television.
The remote control is provided with an annular selector, that is, an annular jog operation key. The annular selector may rotate clockwise or counterclockwise around a circumference. In operation, the remote control sends the acquired rotation information of the annular selector to the interaction apparatus of the television, and the interaction apparatus controls, according to the rotation information, rotation of a menu or cursor on a display interface. The rotation information includes a rotational direction. For example, clockwise rotation is forward rotation, and counterclockwise rotation is reverse rotation. The rotation information may further include a rotational speed. For example, a circumferential displacement, by which a certain marked position of the annular selector rotates per unit time, is acquired through a displacement sensor, and the rotational speed is determined according to a relationship between the displacement and the time. Alternatively, in an exemplary embodiment of the remote control 002 shown in FIG. 9, multiple striking pins 201 are disposed on the annular selector 200, and the number of strikes of the striking pins 201 per unit time and a preset spacing distance between the striking pins 201 are acquired, so as to obtain a circumferential displacement by which the annular selector 200 rotates, thereby determining the rotational speed. For example, the preset spacing distance between the striking pins 201 may be pre-defined; and the number of strikes of the striking pins 201 per unit time can be obtained by a detector or sensor 202 disposed under the striking pins 201.
At step S102: a rotational displacement of the menu or cursor according to the rotation information is obtained.
On the display interface, the shape of the menu is designed to be annular or arc-shaped. A cursor layer and a menu layer on the display interface of the television overlap, such that a certain option of the menu on which the cursor falls is in a highlighted state. The television may adopt two methods to control selection of the menu on the display interface. In one embodiment, the position of the cursor is fixed, and the interaction apparatus of the television analyzes the rotation information of the annular selector to obtain the rotational displacement of the menu, so as to control rotation of the menu. In the other embodiment, the position of the menu is fixed, the interaction apparatus of the television obtains the rotational displacement of the cursor, so as to control rotation of the cursor.
At step S103: the menu or cursor is redrawn on the display interface according to the rotational displacement, so as to control the menu or cursor to rotate according to the rotational displacement.
For design of an animation of the menu or cursor, in conjunction with operation of the annular selector, the animation of the menu or cursor is designed to have a rotational effect. When the annular selector on the remote control rotates, the rotational displacement of the menu or cursor is calculated according to different speed levels, and the menu or cursor is redrawn according to the rotational displacement. When a rotational displacement is incurred, the television draws the menu or cursor once for each passed preset time T, which is reflected on the display interface by that the menu or cursor performs circumferential rotation at a corresponding speed, and if the menu is bar-shaped, is reflected on the display interface by that the menu or cursor switches or jumps at a corresponding speed.
At step S104: a confirmation signal sent by the remote control is received, and an option, corresponding to a position where the cursor is, on the menu is then selected.
After the menu or cursor stops rotation, the cursor stops on a certain option on the menu. If the option is an item required by the user, after the user clicks an Ok button of the annular selector, the remote control sends the confirmation signal to the television, and the television completes the selection. Further, when the menu or cursor rotates, if Ok, Up, Down, Left, or Right button of the annular selector is clicked, the menu or cursor on the display interface stops rotation immediately, thereby achieving precise positioning.
In this embodiment, the annular selector is configured to select content. When the annular selector is rotated rapidly, the speed of the jumping by the cursor between different contents on the menu increases, and when the rotation action stops, precise positioning can be achieved. For operational design of the annular selector of the remote control, a visual menu interface is also expressed in an annular manner, and an annular rotational animation is also adopted for an animation effect, so that an action incurred by the user operating the remote control is consistent with a result seen on the television interface by the user. The physical operation and the visual effect match each other, the operation is simple, and the display is intuitive, so as to greatly reduce operation complexity and fatigue, thereby effectively improving a human-computer interaction experiences.
FIG. 2 is a flow chart of a second embodiment of the method for annular-selector based television interaction according to the present invention. The method in this embodiment includes the following steps.
At step S201: Receiving a rotational direction and a rotational speed V of an annular selector within a preset time T that are sent by a remote control provided with the annular selector.
At step S202: Obtaining a rotational displacement S=V×T by which a menu or cursor rotates at the rotational speed V within the preset time T.
According to the rotational direction and the rotational speed of the annular selector, different levels of speed are output. Different levels of speed have different key values. Upon receiving the key values, the television may first input speed values to a physical mechanical model, output different speeds and acceleration after simulation calculation of the mechanical model, and then use the states to control a rotational state of the annular selector and a switch state between various menu options. In order to make the menu or cursor be reflected on a display interface by continuous rotation, the preset time T may be set to a small value, for example, 0.1 second, the remote control acquires the rotational speed of the annular selector for each 0.1 second, and within the 0.1 second, it may be regarded that the annular selector performs uniform rotation at the rotational speed V, to which the menu or cursor of the television corresponds, so that the menu or cursor also performs uniform rotation at the rotational speed V within the 0.1 second.
At step S203: Redrawing the menu or cursor on the display interface according to the rotational displacement S, so as to control the menu or cursor to rotate according to the rotational displacement S.
At step S204: Receiving a confirmation signal sent by the remote control, and select an option, corresponding to a position where the cursor is, on the menu.
In this embodiment, in order to best simulate a realistic state of jog operation key rotation on the annular selector, the physical mechanical model is introduced to the television processing the display interface, to simulate a motion state of the annular selector in a real state. When the annular selector is rotated at a certain speed, rotation of the same speed shall be reflected on a ring or ring-shaped menu or cursor, and switching of the same speed shall be reflected on other strip-shaped menu options. When the rotation is not stopped yet and a certain speed is provided again, the rotation or switching shall obtain certain acceleration, and acceleration or deceleration of the rotation or switching is performed, thereby effectively improving a human-computer interaction experiences.
FIG. 3 shows a flow chart of a third embodiment of the method for annular-selector based television interaction according to the present invention.
At step S301: Receiving a rotational direction of an annular selector and the number of strikes of striking pins of the annular selector within a preset time T that are sent by a remote control provided with the annular selector.
While a user is sliding the annular selector, the remote control acquires, within the preset time T, the number of strikes on the internal striking pins of the annular selector, so as to transmit a value to a processor of a television for processing. During the process, if the annular selector slides faster, the number of strikes on the striking pins increases, and the transmitted value increases.
At step S302: According to the number of strikes of the striking pins, searching a preset transmitted-value mapping table for a corresponding external rotation force F.
The television may obtain a rotational speed of the annular selector according to the number of strikes of the striking pins. As a sliding speed changes gradually, a value may be mapped to within a given range, and according to a relationship between a speed and a force, the external force applied to the annular selector may be simulated. The transmitted-value mapping table is preset in the television. For example, when the number of strikes on the striking pins of the annular selector within the preset time T is 10-15, the force is 1.3 N. Therefore, a jog operation key transmitted-value mapping table in the following may be obtained.

At step S303: Obtaining a rotational displacement S of a menu or cursor under the external rotation force F after the preset time T.
The television simulates a rotation process of the menu or cursor under the external rotation force F in a physical mechanical model, acceleration a1=(F−f)/M, where f is a preset frictional force applied to the menu or cursor, M is preset mass of the menu or cursor. The following three situations are included: in a situation where an initial rotational speed is 0, the rotational direction of the annular selector determines that the menu or cursor performs accelerated motion in the rotational direction, and the rotational displacement S=a1T2/2; in a situation where the initial rotational speed is not 0, a rotational direction consistent with the direction of the initial rotational speed V0 may make the menu or cursor perform accelerated motion in the rotational direction, and the rotational displacement S=V0 T+a1T2/2; in a situation where the initial rotational speed is not 0, a rotational direction opposite to the direction of the initial rotational speed may make the menu or cursor perform retarded motion in the direction opposite to the rotational direction, and the rotational displacement S=V0 T−a1T2/2, until the menu or cursor stops or performs acceleration in the opposite direction.
At step S304: Redrawing the menu or cursor on the display interface according to the rotational displacement S, so as to control the menu or cursor to rotate according to the rotational displacement S.
At step S305: Receiving a confirmation signal sent by the remote control, and select an option, corresponding to a position where the cursor is, on the menu.
In this embodiment, when the annular selector is in acceleration, the rotational displacement output by the physical model is configured to control the rotational state of the menu or cursor or switching of other options. Through cooperation between the annular selector and the menu/cursor, when the number of options is large or very large, the user may perform rapid rotation or accelerated rotation, so that the annular selector or other option can be rapidly positioned near a target option, and then through a immediate halt, reverse motion or slow motion, precisely positioned on the target option, thereby not only bringing rapidness and convenience to selection, but also greatly improving selection accuracy.
As shown in FIG. 4, a flow chart of the method for annular-selector based television interaction is shown according to a fourth embodiment of the present invention. The method includes the following steps.
At step S401: Receiving a rotational direction of an annular selector and the number of strikes of striking pins of the annular selector within a preset time T that are sent by a remote control provided with the annular selector.
At step S402: According to the number of strikes of the striking pins, searching a preset transmitted-value mapping table for a corresponding external rotation force F.
At step S403: Obtaining a rotational displacement S of a menu or cursor under the external rotation force F after the preset time T.
At step S404: Redrawing the menu or cursor on a display interface according to the rotational displacement S, so as to control the menu or cursor to rotate according to the rotational displacement S.
At step S405: After it is determined that the external rotation force F is removed, obtaining a rotational displacement S′ through which the menu or cursor decelerates to a halt.
At step S406: Redrawing the menu or cursor on the display interface according to the deceleration-to-halt rotational displacement S′, so as to control the menu or cursor to rotate according to the deceleration-to-halt rotational displacement S′.
After the external rotation force F is removed, a television simulates a deceleration process, where the menu or cursor is only subject to a frictional force f, in a physical mechanical model, acceleration a2=f/M, where f is a preset frictional force applied to the menu or cursor, and M is preset mass of the menu or cursor. The direction of the frictional force f is opposite to that of an initial rotational speed V0, the rotational displacement S′=V0 T−a2T2/2 until a halt is reached.
At step S407: Receiving a confirmation signal sent by the remote control, and select an option, corresponding to a position where the cursor is, on the menu.
In this embodiment, rotation of a realistic dial is simulated, and different rotational speeds incur different effects. For no matter slow rotation or rapid rotation, a deceleration process subject to constant damping shall always follow the stop of the rotation. A short deceleration process follows the stop of the slow rotation, and a long deceleration process follows the stop of the rapid rotation. When a jog operation key is rotated again, and if rotation of the jog operation key is not stopped yet at the moment, acceleration shall be obtained again, and accelerated rotation is performed. After the physical mechanical model is added, manipulation of the menu or cursor can best simulate a realistic state, so that a user uses the annular selector in a most natural state. When the annular selector is rotated, the menu or cursor on the television is like a real dial, and can be rotated arbitrarily; or during switching of other bar-shaped menu options, experience of rapidness and slowness can be obtained. The operation by the hand of the user is completely converted into an effect viewed on the television, so as to comply with operation habits of the user, thereby incurring desirable experience.
Referring to FIG. 5, a schematic structural view of an apparatus for annular-selector based television interaction is shown according to a first embodiment of the present invention. In the embodiment, the apparatus 100 is disposed in a television 001, and includes a receiving module 110, configured to receive rotation information of an annular selector 200 sent by a remote control 002 provided with the annular selector 200; an obtaining module 120, configured to obtain a rotational displacement S of a menu or cursor according to the rotation information; a drawing module 130, configured to redraw the menu or cursor on a display interface according to the rotational displacement S, so as to control the menu or cursor to rotate according to the rotational displacement S; and a confirmation module 140, configured to receive a confirmation signal sent by the remote control 002, and select an option, corresponding to a position where the cursor is, on the menu.
In this embodiment, the remote control 002 is provided with the annular selector 200, that is, an annular jog operation key. The annular selector 200 may rotate clockwise or counterclockwise around a circumference. The remote control 002 sends the acquired rotation information of the annular selector 200 to the receiving module 110. The television 001 controls, according to the rotation information, rotation of the menu or cursor on the display interface. The rotation information includes a rotational direction. For example, clockwise rotation is forward rotation, and counterclockwise rotation is reverse rotation. The rotation information may further include a rotational speed. For example, a circumferential displacement, by which a certain marked position of the annular selector 200 rotates per unit time, is acquired through a displacement sensor, and the rotational speed is determined according to a relationship between the displacement and the time; alternatively, multiple striking pins are disposed on the annular selector 200, and the number of strikes of the striking pins per unit time and a preset spacing distance between the striking pins are acquired, so as to obtain a circumferential displacement by which the annular selector 200 rotates, thereby determining the rotational speed. On the display interface, the menu is designed to be annular or arc-shaped. A cursor layer and a menu layer on the display interface of the television overlap, and the cursor falls on the menu, which is reflected on the display interface by that a certain option on the menu is in a highlighted state. The television 001 may adopt two methods to control selection of the menu on the display interface. In one method, the position of the cursor is fixed, and the obtaining module 120 analyzes the rotation information of the annular selector 200 to obtain the rotational displacement S of the menu, so as to control rotation of the menu. In the other method, the position of the menu is fixed, the obtaining module 120 obtains the rotational displacement S of the cursor, so as to control rotation of the cursor.
For design of an animation of the menu or cursor, in conjunction with operation of the annular selector 200, the animation of the menu or cursor is designed to have a rotational effect. When the annular selector 200 on the remote control 002 rotates, the television 001 uses the obtaining module 120 to calculate the rotational displacement S of the menu or cursor according to different speed levels, and uses the drawing module 130 to redraw the menu or cursor. When a rotational displacement S is incurred, the drawing module 130 draws the menu or cursor once for each passed preset time T, which is reflected on the display interface by that the menu or cursor performs circumferential rotation at a corresponding speed, and if the menu is bar-shaped, is reflected on the display interface by that the menu or cursor switches or jumps at a corresponding speed. After the menu or cursor stops rotation, the cursor stops on a certain option on the menu. If the option is an item required by a user, after the user clicks an Ok button of the annular selector 200, the remote control 002 sends the confirmation signal to the confirmation module 140, and the television 001 completes the selection. Further, when the menu or cursor rotates, if Ok, Up, Down, Left, or Right button of the annular selector 200 is clicked, the menu or cursor on the display interface stops rotation immediately, thereby achieving precise positioning.
In this embodiment, the annular selector 200 is configured to select content. When the annular selector 200 is rotated rapidly, the television 001 increases the speed of the jumping by the cursor between different contents on the menu, and when the rotation action stops, precise positioning can be achieved. For operational design of the annular selector 200 of the remote control 002, the television 001 express a visual menu interface also in an annular manner, and an annular rotational animation is also adopted for an animation effect, so that an action incurred by the user operating the remote control 002 is consistent with a result seen on the television interface by the user. The physical operation and the visual effect match each other, the operation is simple, and the display is intuitive, so as to greatly reduce operation complexity and fatigue, thereby effectively improving a human-computer interaction experiences.
FIG. 6 shows a schematic structural view of a second embodiment of the apparatus for annular-selector based television interaction according to the present invention. The apparatus disposed in a television 001, among other things, includes a receiving module 110, an obtaining module 120, a drawing module 130, and a confirmation module 140.
In one embodiment, the receiving module 110 includes a first receiving sub-module 111, configured to receive a rotational direction and a rotational speed V of an annular selector 200 within a preset time T that are sent by a remote control 002 provided with the annular selector 200.
The obtaining module 120 includes a first displacement obtaining sub-module 121, configured to obtain a rotational displacement S=VT of a menu or cursor within the preset time T when the menu or cursor rotates at the rotational speed V.
In this embodiment, according to the rotational direction and the rotational speed of the annular selector 200, different levels of speed are output. Different levels of speed have different key values. After the first receiving sub-module 111 receives the key values, the first displacement obtaining sub-module 121 may first input speed values to a physical mechanical model, output different speeds and acceleration after simulation calculation of the mechanical model, and then use the states to control a rotational state of the annular selector 200 and a switch state between various menu options. In order to make the menu or cursor be reflected on a display interface by continuous rotation, the preset time T may be set to a small value, for example, 0.1 second, the remote control 002 acquires the rotational speed of the annular selector 200 for each 0.1 second, and within the 0.1 second, it may be regarded that the annular selector 200 performs uniform rotation at the rotational speed V, to which the menu or cursor of the television 001 corresponds, so that the menu or cursor also performs uniform rotation at the rotational speed V within the 0.1 second. In this embodiment, in order to best simulate a realistic state of jog operation key rotation on the annular selector 200, the physical mechanical model is introduced to the television 001 processing the display interface, to simulate a motion state of the annular selector 200 in a real state. When the annular selector 200 is rotated at a certain speed, rotation of the same speed shall be reflected on a ring or ring-shaped menu or cursor, and switching of the same speed shall be reflected on other strip-shaped menu options. When the rotation is not stopped yet and a certain speed is provided again, the rotation or switching shall obtain certain acceleration, and acceleration or deceleration of the rotation or switching is performed, thereby effectively improving a human-computer interaction experiences.
FIG. 7 shows a schematic structural view of a third embodiment of the apparatus for annular-selector based television interaction according to the present invention.
In this embodiment, the receiving module 110 includes a second receiving sub-module 112, configured to receive a rotational direction of an annular selector 200 and the number of strikes of striking pins of the annular selector 200 within a preset time T that are sent by a remote control 002 provided with the annular selector 200.
The obtaining module 120 includes an external rotation force query sub-module 122, configured to, according to the number of strikes of the striking pins, search a preset transmitted-value mapping table for a corresponding external rotation force F; and a second displacement obtaining sub-module 123, configured to obtain a rotational displacement S of a menu or cursor under the external rotation force F after the preset time T.
In this embodiment, while the annular selector 200 is sliding, the remote control 002 acquires, within the preset time T, the number of strikes on the internal striking pins of the annular selector 200, so as to transmit a value to the second receiving sub-module 112. If the annular selector 200 slides faster, the number of strikes on the striking pins increases, and the transmitted value increases. The external rotation force query sub-module 122 may obtain a rotational speed of the annular selector 200 according to the number of strikes of the striking pins. As a sliding speed changes gradually, a value may be mapped to within a given range, and according to a relationship between a speed and a force, the external force applied to the annular selector 200 may be simulated. The transmitted-value mapping table is preset in the television 001. For example, when the number of strikes on the striking pins of the annular selector 200 within the preset time T is 10-15, the force is 1.3 N. Therefore, a jog operation key transmitted-value mapping table in the following may be obtained.

The second displacement obtaining sub-module 123 simulates a rotation process of the menu or cursor under the external rotation force F in a physical mechanical model, acceleration a1=(F−f)/M, where f is a preset frictional force applied to the menu or cursor, M is preset mass of the menu or cursor. The following three situations are included: in a situation where an initial rotational speed is 0, the rotational direction of the annular selector 200 determines that the menu or cursor performs accelerated motion in the rotational direction, and the rotational displacement S=a1T2/2; in a situation where the initial rotational speed is not 0, a rotational direction consistent with the direction of the initial rotational speed V0 may make the menu or cursor perform accelerated motion in the rotational direction, and the rotational displacement S=V0 T+a1T2/2; in a situation where the initial rotational speed is not 0, a rotational direction opposite to the direction of the initial rotational speed may make the menu or cursor perform retarded motion in the direction opposite to the rotational direction, and the rotational displacement S=V0 T−a1T2/2, until the menu or cursor stops or performs acceleration in the opposite direction.
In this embodiment, when the annular selector 200 is in acceleration, the rotational displacement output by the physical model is configured to control the rotational state of the menu or cursor or switching of other options. Through cooperation between the annular selector 200 and the menu/cursor, when the number of options is large or very large, the user may perform rapid rotation or accelerated rotation, so that the annular selector 200 or other option can be rapidly positioned near a target option, and then through a immediate halt, reverse motion or slow motion, precisely positioned on the target option, thereby not only bringing rapidness and convenience to selection, but also greatly improving selection accuracy.
Referring to FIG. 8, a schematic structural view of a fourth embodiment of the apparatus for annular-selector based television interaction is shown according to the present invention.
In this embodiment, the obtaining module 120 further includes a third displacement obtaining sub-module 124, configured to, after it is determined that the external rotation force F is removed, obtain a rotational displacement S′ through which a menu or cursor decelerates to a halt.
The drawing module 130 is further configured to redraw the menu or cursor on the display interface according to the deceleration-to-halt rotational displacement S′, so as to control the menu or cursor to rotate according to the deceleration-to-halt rotational displacement S′.
In this embodiment, after the external rotation force F is removed, the third displacement obtaining sub-module 124 simulates a deceleration process, where the menu or cursor is only subject to a frictional force f, in a physical mechanical model, acceleration a2=f/M, where f is a preset frictional force applied to the menu or cursor, and M is preset mass of the menu or cursor. The direction of the frictional force f is opposite to that of an initial rotational speed V0, the rotational displacement S′=V0 T−a2T2/2 until a halt is reached. In this embodiment, the third displacement obtaining sub-module 124 simulates rotation of a realistic dial, and different rotational speeds incur different effects. For no matter slow rotation or rapid rotation, a deceleration process subject to constant damping shall always follow the stop of the rotation. A short deceleration process follows the stop of the slow rotation, and a long deceleration process follows the stop of the rapid rotation. When a jog operation key is rotated again, and if rotation of the jog operation key is not stopped yet at the moment, acceleration shall be obtained again, and accelerated rotation is performed. After the physical mechanical model is added, manipulation of the menu or cursor can best simulate a realistic state, so that a user uses the annular selector 200 in a most natural state. When the annular selector 200 is rotated, the menu or cursor on the television is like a real dial, and can be rotated arbitrarily; or during switching of other bar-shaped menu options, experience of rapidness and slowness can be obtained. The operation by the hand of the user is completely converted into an effect viewed on the television, so as to comply with operation habits of the user, thereby incurring desirable experience.

In one embodiment, the remote control includes an annular selector, operably rotatable clockwise or counterclockwise; means for acquiring rotation information of the annular selector; and a transmitter for sending the acquired rotation information of the annular selector to the apparatus that controls, according to the rotation information of the annular selector, rotation of a menu or cursor on a display interface on a television, and for sending a confirmation signal to the apparatus when a certain option of the menu on which the cursor falls is selected. The rotation information comprises at least one of a rotational direction, a rotational speed, and a circumferential displacement.
