Description

{Method, device and input element for selecting the functional mode}

TECHNICAL FIELD The present invention relates to adaptive tactile techniques, and more particularly, to emulating functional modes of specific input elements by a general purpose input element using state transitions between control characteristics and other control characteristics. The present invention is specifically used in the mobile terminal device environment, but is not limited thereto.

To date, special cases for haptics and its force-feedback effects have been used primarily to achieve two purposes. They are used in remote control robot devices and the like. For example, tactile techniques can be quite useful or even essential to successfully catch an object with a remotely controlled robot. If the object is easily broken, for example in the case of eggs, the grip force applied to the object must be limited. Therefore, in order to catch the object with proper force, the human coordinator must receive force-feedback. In the case of operating such a robot device, the above object can be achieved by using a tactile effect of transmitting a tactile response or the like. This issue can also be applied to applications that simulate the feedback effect on the game controller, which shows the tactile technique of a real controller, for example, applications such as flight simulation.

In many computer games, force-feedback effects may make the game more realistic. In car racing or flight simulation, force-feedback is used to emulate the feedback presented by real controllers such as steering wheels and the like. Also, in computer applications, the mouse is given a force-feedback effect, which is mainly used not only for use in computer games, but also for sending tactile signals when the mouse is placed on top of any dialog or menu item. do. However, the latter is not used extensively, since its possible use is obviously less in combination with fixed computers.

An important problem associated with mobile terminal devices such as cell phones or PDAs is to make the screen as large as possible and at the same time the size of the entire device as small as possible. The obvious paradox of large screens on the one hand and the size of a pocket on the other hand can be achieved simply by reducing the space occupied by the control of the device. Therefore, it is desirable to use a very small number of input elements, most preferably only one input element.

Another challenge may be that the device can be used without actually looking at the portable device.

So far, no force-feedback effect or restoring force on the input elements has been implemented in the mobile terminal device. There are at least two main reasons for avoiding the use of force-feedback in small mobile devices. The power consumption of the force-feedback elements is, of course, ambiguous for mobile devices containing only a limited amount of energy, but is expected to be quite high. Also, since the force-feedback elements in such a small mobile device must be small enough to be sufficient, it is certain that a fairly strong force cannot be applied, which may be useless because the force-feedback effects are simply weak.

To date, the input elements used in mobile terminal devices include joystick-like elements that are movable in two dimensions perpendicular to each other and require four-way switches, rocker keys or rollers that are required to be pressed or biased relative to the reference plate. It may also contain additional things called (rollers). Rotors are not yet widely used, but may become more important in the form of future mobile terminal devices. Depending on the application to be manipulated, input elements such as rollers or rotors used for volume control, rocker keys for navigation menus, and joystick likes for game applications, etc., are used. At least one or even all of the generally mentioned applications, such as navigation menus, games running on the terminal, or a built-in MP3 player that needs to be resized, may be mounted to the mobile terminal device. Of course, providing specific input elements corresponding to each application may be uncertain to reduce the space occupied by such control elements. Nevertheless, on the other hand, these input elements Easy to use and convenient

In the development of mobile phones, it must be done somewhat early to limit the use of any kind of input element. This is due to the functions and features to be controlled, the menu structure and other options.

Recently, the use of games in mobile communication devices has greatly increased. Most games require control by input elements that can move in two dimensions, that is, in four directions. However, other common menu functions are already adequate enough for one-dimensional, ie up and down movement. It may often be desirable to press the joystick, rocker key, or middle portion of the roller to confirm input or to perform a command. Thus, it is clearly desirable to aggregate many of the advantages of the aforementioned input elements over one input element if possible.

With the advent of resistive or active force-feedback, input elements have begun to implement dynamic behavior that can be changed by the application of context-dependent forces. In the automotive sector, the use of programmable tactile techniques has already been partially completed. Single mechanical inputs with some adaptable characteristics are employed in high-end vehicles. The best known example is the i-drive® knob in the BMW® 7 series. This knob is programmable in that it can program the number of brakes or detents (ie rasterization) and the force-feedback can be adjusted by software. Vibration detection is also performed here.

Current implementations are preprogrammed only for a single input situation. This means, for example, that one menu is represented in the hierarchy of the user interface. In addition, the degree of freedom of movement of such mechanical input elements is fixed and not changeable or dynamically adapted. So far, the force-feedback effect is only used to support the operation of the input element, or in the game domain, only to achieve more realistic game performance. In other words, current implementations are limited to closed input situations, ie those that are only adapted for one use or one specific purpose at a time.

DE 4205875 Al discloses adaptation of the resilience to the use of a rotor in the BMW® 7 model.

In EP 794089 A2 a rotor similar to the above is disclosed, which device has one or more degrees of freedom and can also be indirectly controlled via oral input.

US 6005551 discloses the execution of a series of tactile effects. This means that the output behavior changes, but not dynamically controlled by the user or other entities.

In US Pat. No. 5,889,672, the "torque profile" describes the bottom layer parameters of a vibration (actuator) device. The parameter may adjust the behavior of the rotor shift of the actuator. Such parameter sets are typically stored in EEPROM or similar media located in the controller portion of the device. Once a parameter set has been adjusted on one device, it cannot be changed until the controller section is flashed.

In WO 98/43261, adaptive resilience to rotors and joysticks is disclosed in particular. It is not disclosed to emulate the function of the rotor with the joystick, or vice versa.

It is an object of the present invention to provide a flexible method for adapting haptic technology for other purposes and an input element that combines the advantages of other conventional input elements.

In order to achieve the above technical problem, there is provided a method of allowing an input element of a mobile terminal device to emulate a functional mode for another type of conventional input elements. Accordingly, the method uses control features to limit or allow any degree of freedom of the input element. A corresponding mobile terminal device comprising a multi mode input element is provided, through which the functional modes of two or more input elements are emulated.

For rocker keys, a contact response, for example, a click, tells the user that the direction key is used or that the input is confirmed (similar to pressing the enter key). In joysticks used to control the game, such clicks are generally used in any situation in the game where clicks may be useful, for example, when the game mode changes, or when other functions need to be controlled. Is not required. Simple one-dimensional control (two directions), with or without clicks, is already adequate for scrolling lists of other menu areas. Through the use of adaptive resilience or resistance, these functions of the input element may be emulated as the same as a general purpose input element, which makes the use of the communication device more convenient in other operating situations.

The mechanical state or position of the input elements (also output elements) can be described by finite variables or finite coordinates. In the case of a rotor, ie a disc capable of simple rotation, its position is indicated by the angle of rotation α in one-dimensional coordinates. In the case of joysticks, spherical variables are the most convenient for describing the position. The angle θ determines the direction of the joystick pointer, the tilt angle φ measures the degree of deviation from the vertical axis, and the radius r outlines the case where the joystick is pressed against the surface of the device. In general, this is a simple binary decision variable, ie pressurized or unpressurized. In the same way, switch or key functionality may be added to other input elements, such as the rotor mentioned above, by adding a binary variable and corresponding degrees of freedom. The added degrees of freedom are rotatable about the z-axis and can be easily explained by the angles added.

According to the present invention, a method of selecting a function mode in an input element for a mobile terminal device is provided.

The function mode selection method is:

Accordingly, the general purpose input elements can adopt the behavior of other types of normal input elements.

Advantageously, said control characteristic is created in accordance with the parameters of the required functional mode. According to this method, it is not necessary to store a plurality of control characteristics, and suitable control characteristics may be generated from a relatively small number of parameters (degrees of freedom, limits, etc.).

Preferably, when the input element is brought into a certain mechanical state, a state transition to another control characteristic is caused. According to this method, the control characteristic can be operated very flexibly. State transitions allow the construction of very complex operating situations.

In the following description, a spherical coordinate system may be used for the position of the upper part of the mechanical input element. In the spherical coordinate system, r∈ [0, f], θ∈ [-π, π], and φ∈ [0, π / 2]. The mathematical concept of spherical coordinates is shown in FIG.

1 shows a control characteristic according to the invention. Exemplary control characteristics A) include two-dimensional regions spanning the x and y axes, as well as additional z-axis. The force-feedback intensity increases with the z indicated by the arrow F. This control characteristic may represent a device, and the mechanical state of the control characteristic may be described in two coordinates, for example x and y. The corresponding control characteristic is related to the force-feedback values in addition to the position value of the input element, or in this case two-cell tuples of x and y. For a given tuple corresponding to any position of the joystick, the feedback value on the z axis is assigned. When the position of the joystick reaches one of the T regions, a state transition to another control characteristic B) or C) occurs. This new control feature is now used to check the force-feedback values corresponding to the joystick position. The T region at the other position returns to the starting control characteristic.

The above exemplary control characteristics, which relate the two-dimensional positions of the x-y plane on the z axis with the force-feedback scalar value, are rather simple. Although not easy to illustrate, it is possible to use, with feedback vector values, control characteristics related to position values of two or more dimensions, additional rotation about the z axis of the input element, pressed or unpressurized input element, and the like. Therefore, it is possible to assign not only the strength of any feedback effect but also the direction of the force-feedback effect to be applied. Therefore, such control characteristics can be flexibly configured to actually complex assignments, given the desired force-feedback values and directions in the much required actual configuration of the input element.

2 shows an input element according to the invention. A joystick with different degrees of freedom is shown. Compared to a given Cartesian coordinate system, the spherical coordinate system used is shown. The joystick may be pressurized, which can be seen by measuring the radius r. The r value has a relatively large value when not pressurized, and the r value decreases when pressed. The joystick may rotate about the z axis, which is not represented in the standard spherical coordinate system but may be further measured by the angle α. The pointer of the joystick may move in the y direction in the rectangular coordinate system, which means that the angle θ becomes 0 (for forward movement) or π (for backward movement). On the other hand, the inclination angle φ changes depending on how far the pointer of the joystick has moved. Similarly, the pointer of the joystick may move along the x axis (left or right) in the Cartesian coordinate system. In this case, the angle θ is π / 2 (when moving right) or -π / 2 (when moving left). Of course, all possible movements may occur together. The joystick device illustrated herein may be suitable as a basis for adaptive joystick implementation, which may be dynamically converted between analog joystick, rocker and roller modes, or more specific operating modes.

3 shows a simple application. In this case, it is an application that is converted between different menu hierarchies within the user interface. Shown here is a user interface that includes three levels of menu hierarchy. When the position value of the corresponding input element reaches the "up menu" area of the control characteristic b), the conversion to the control characteristic a) is effected, and the user interface is converted to the upper menu level. On the other hand, when reaching the "down menu" area of the control characteristic b), the conversion to the control characteristic c) is effected and the user interface is switched to the lower menu level. Upon contacting the state transition area, the touch sensation provides user feedback to indicate that the menu levels have been converted. For each control characteristic, menu items such as 1 to 3, or 2.1 to 2.4 are further indicated by different menu surfaces and conversion areas and different feedback values as shown in the control characteristics. do. Therefore, the user can also feel the menu structure visually and tactilely. This can be accomplished by applying a resilience-feedback effect upon entering a region corresponding to any menu item. In other words, construct an attractor for the menu item. For each menu level, the corresponding control characteristics represent menu items. In this case, the upper level is 3, the middle level is 4, and the lower level is 2. Of course, the user can switch from the upper or lower menu to the middle menu in order to avoid inadvertent and undesired inversion to the remaining menu level. For example, it ends in the middle of the control characteristic corresponding to the median menu. In general, state transition zones or regions within the same control characteristic should always be substantially separated within the menu operating environment or the like, otherwise unwanted state transitions may easily occur. In other applications, this does not appear or is required.

4 shows control characteristics corresponding to a simple one-way rocker key or switch. The feedback force increases with z as indicated by arrow F. Here, the general purpose mechanical input element is confined by zone 3 to θ = π / 2 and the angle φ to a small area from zero, for example up to 20 degrees. This means that the switch can be moved slightly horizontally to the right. If the user moves the switch out of the home position, the inclination angle φ increases. Up to this point the input element moves to low resilience-feedback in zone 1. If the angle increases, more elements reach Zone 2 of moderate resistance force-feedback. If the user applies a moderate force through this zone, the input element reaches another zone 1. Passing through this zone is perceived by the user in the form of a click (over resistance). Here, a state transition to the control characteristic at which the intermediate resistive force-feedback zone 2 is terminated occurs, so that the input element can be returned to the home position and follows a low recovery force-feedback. Returning to the home position, a transition back to the original control characteristic occurs, and the rocker key also prepares for another interaction cycle. Due to the function performed by clicking on the rocker key, the conversion between the two control features can of course be associated with a corresponding event caused or converted by the rocker key.

4B shows the concept of an n-direction rocker key when n is four. These four-way rocker keys have two additional directions (upper left, upper right, right) in the horizontal direction (left or right), vertical (up or down), and at an angle of 45 degrees to one of the mentioned directions. Downward, and left downward). The corresponding haptic map is similar to the haptic map of a simple one-way rocker key. Or, in other words, four simple maps for each of four different angles, θ = 0, π / 4, π / 2, 3π / 4, or π. Four possible directions of movement are made according to the simple one-way rocker key of FIG. If the user moves the joystick away from the center position by 0 degrees of inclination, certain directions are blocked, which means that the rocker only moves in any direction to perform the N-direction rocker. In this figure, a four-way rocker is shown in which small areas around θ = −π, −π / 2, 0, or π / 2 are blocked by high resistivity (zone 3). Once the input element moves within the allowed area and the inclination angle θ increases, there is a resistive counter-force (zone 2). If the user applies a greater force to overcome this intermediate resistance, the angle of inclination is further increased and ends in zone 1. Further increase of the inclination angle and having a value near π / 2 is prohibited by large resistivity (zone 3). Once, when the input element passes the middle (zone 2) slope region and reaches zone 1 with a larger tilt angle, a state transition of the tactile map occurs. As a result, the resistive intermediate zone 2 is terminated, and the rocker is allowed to return to the center position with zero inclination angle. If the rocker reaches the center position again, the state transition returns to the initial state. In order to be able to move the rocker in eight directions, the negative values of φ are simply adjusted using their absolute values.

5 shows control characteristics corresponding to a conventional analog joystick. The feedback force increases with z as indicated by arrow F. The angle θ can be any value from -π to π, which means that the joystick pointer can move in all directions. On the other hand, the inclination angle φ is limited from 0 to 20 degrees, which means that the joystick pointer can only deviate by a certain degree from the vertical axis. The recovery force always faces the origin, and the absolute value of the recovery force depends only on the value of the inclination angle φ. For this purpose, certain zones, in this example a range from 0 to 3, are defined and the resilience increases monotonically with zone numbers. Of course, a much larger number of zones are used, for example, in practical analogue analogue controls for gaming purposes. Values greater than 20 degrees, or other fixed appropriate limits, cause strong resilience along zone 3, which cannot be overcome. On the z axis, only the value of the resilience-feedback effect is measured and the direction in which it is applied must be derived from the coordinates of the joystick pointer. In this case, the control characteristic emulates a spring element of an ordinary analog joystick, thereby ensuring a restoring force at the center position (inclined angle? = 0).

6 shows control characteristics corresponding to the roller input element. The feedback force increases with z as indicated by arrow F. The angle θ is limited to a small area around π / 2 by zone 3 with strong resistive force-feedback. The angle φ may have a range of 0 to π. This means that the input element can rotate half a turn to the right. The number of detents can be defined for rasterization. In this case, three detents are defined. Each detent is characterized by an increased resistivity-feedback in Zone 2 which must be overcome compared to the low or zero resistivity of Zone 1. Such a roller may also be embodied as a rotating disk or rotor. It should be noted that in place of the above angle θ, linear coordinates, or angle α, etc. may be used, and if desired, the method may also be angles greater than π. It may be.

7 shows an input element 2 according to the invention. In this case, it is a kind of small joystick and it adjusts with a user's thumb. A recognition element 4 is attached to the control rod of the joystick and is used to determine the mechanical state of the joystick, ie to measure the position or the respective degrees of freedom. The feedback component 6 is attached to the control rod by a simple lever type and applies a force-feedback effect to the joystick.

The foregoing examples illustrate only a few of the possible ways of providing a particular kind of input elements. Using the above method, it is possible to facilitate the implementation of more specific input elements, which behaves like the gear lever in the gear lever gate in a car racing game or the like.

There are at least two main tactile or force-feedback effects. First is a resistive force-feedback, which can be implemented by a braking device having an appropriate braking force or the like. The second is a push or pull feedback, the pushing force or the pulling force in any direction can be sensed by the user. The latter may be implemented by a magnetic driving force applied to the input element. The resistive feedback has only a scalar value corresponding to the braking force. In contrast, a force-feedback that pushes or pulls an input element in any direction, for example, is instead a recovery force vector, the vector providing information about its scalar value as the force of its absolute value, It also provides information about the direction in which the force is applied. Apart from the resistive feedback force, other variables may be suitable in certain situations, but in general resilience-feedback effects are active force-feedback effects in which forces are applied in a direction opposite to the direction in which the user moves the input element. Used. Certain "attractor" regions can be defined by the use of resilience to attract input elements to any region, for example a region corresponding to a menu item or the like.

In order to use the control features, a mechanical input element is required. In order to emulate a wide variety of conventional input elements, the mechanical input elements used must provide many different degrees of freedom. General possibilities can best be explained using joysticks and the like, which are commonly used in computer game applications. Such input elements can be moved or actuated by the following methods:

-rotate around the y axis, the top of the controller moves along the x axis;

rotation around the x axis, the top of the controller moves along the y axis;

-rotate around the z axis;

Pressurized against the basal plane;

These are the most common kinds of movements. Further other movement possibilities may also be implemented.

The concept of adaptive tactile technique according to the invention is based on state transitions between different control characteristics. The mechanical state or position of the tactile input element is continuously scanned by the firmware of the mobile terminal device. Once a user moves the tactile input element into a limited mechanical state change region within the control characteristic, a state transition to a new control characteristic occurs. In this case, the mechanical state transition may be said to be user-induced or dynamic within control characteristics.

There may be other possibilities for converting the control characteristic by the application running the mobile terminal device, that is to say to cause a state transition. Many of the possibilities for such behavior may be due to expiration after a certain time interval, such as in a game, or, for example, to change the control characteristics at a screen frame rate or game situation in the game. It might seem useful to match based on external events such as Therefore, such behavior can be said to be application-induced. Instead, external entities can drive state changes of the control characteristics. The service running on the network to which the mobile terminal is connected may perform coordinated execution, or perhaps be a remote user of another terminal on the same network. It should be noted that the state transitions may rely on the selection of input options, eg, pressing the rotor element, or may be performed without direct selection of the input options.

The use of control features and state transitions provides a wide range of flexibility. It is possible to reduce the total number of input elements used in the mobile terminal device by emulating the use of general purpose mechanical input elements and the like and the number of special conventional input elements. Directional guides obtained by limiting any degree of freedom of the input element may be suitable for assisting other physical features of users, for example, small hands and large hands. Through state transitions between different control features, very complex operating scenarios can be implemented. They may be used intuitively or even for the purposes of operating mobile terminal devices without actually looking at the terminal screen. The conversion of control features may be caused or controlled by a variety of situations or entities, such as internal or external, busy, or part of the state of the software. External events or entities may be services running on the network to which the terminal is connected, applications on the terminal, remote users (in terminal interaction), and the user (adaptability behavior). Therefore, tactile behavior is also learned voluntarily, which means that the force applied through the force-feedback effect can be automatically adapted to the individual user.
