The present invention relates to a mouse device, and more particularly to a multi-function mouse device.
With increasing development of science and technology, multimedia products and computers become essential in our daily lives. In the computer systems, input devices play important roles for communicating the computer host and the user. The widely-used input devices include for example mouse devices, keyboard devices or trackballs. Among these input devices, mouse devices are the most prevailing because they are very easy-to-use. When a mouse device is held by a user's palm, the user may move the mouse to control movement of the cursor shown on the computer screen. In addition, by manipulating the buttons of the mouse device with the user's fingers, the user may click and select a desired icon shown on the computer monitor or execute a corresponding function.
From the above discussions, the conventional wheel mouse device has only the cursor control function when the conventional wheel mouse device is moved by the user. For executing a specified command, the user has to move the mouse device to have the cursor move to a specified computer program icon and then click the icon to execute the specified command.
For solving the above drawbacks, a mouse device capable of executing a special function has been disclosed. The mouse device is equipped with a functional button. After the functional button of the mouse device is pressed down, the computer host executes a corresponding command according to a motion trajectory of the casing. For example, if the casing of the mouse device is moved to a specified distance in the left direction after the functional button is pressed down, a “Backward” function is implemented to allow the graphic-based window (e.g. a web browser) shown on the computer monitor browsing page to go backward to the previous page. The above technologies have been disclosed in for example Taiwanese Patent No. 1406157 and Taiwanese Patent Publication No. 200939077, and are not redundantly described herein.
However, since the multimedia technologies and various application programs are gradually developed in recent years, the interface of the graphic-based window of the computer becomes more complicated and more diversified. Under this circumstance, the functions provided by the above mouse device are gradually insufficient to meet the user's requirements.
Therefore, it is important to increase the functions of the mouse device without the need of additionally installing the functional button. Consequently, the space within the casing of the mouse device can be saved.
The present invention provides a multi-function mouse device for providing a predetermined function according to a moving distance and a motion trajectory.
In accordance with an aspect of the present invention, there is provided a multi-function mouse device. The multi-function mouse device is in communication with a computer host for controlling a cursor shown on a computer monitor. The computer monitor is in communication with the computer host. The multi-function mouse device includes a casing, a displacement sensing module, a mode selection element, and a controlling unit. The casing has a casing surface. The displacement sensing module is disposed within the casing. The displacement sensing module generates at least one displacement amount signal in response to movement of the casing. The mode selection element is disposed on the casing surface. When the mode selection element is triggered, an enabling signal is generated. The controlling unit is connected with the displacement sensing module and the mode selection element for receiving the at least one displacement amount signal, thereby judging a motion trajectory of the casing. If the controlling unit judges that the motion trajectory is not larger than a predetermined distance and the enabling signal is received, the controlling unit issues a first predetermined function signal to the computer host, so that a first predetermined command corresponding to the first predetermined function signal is executed by the computer host according to the first predetermined function signal. Whereas, if the controlling unit judges that the motion trajectory is larger than the predetermined distance and the enabling signal is received, the controlling unit issues a second predetermined function signal to the computer host according to the motion trajectory, so that a second predetermined command corresponding to the second predetermined function signal is executed by the computer host according to the second predetermined function signal.
The above objects and advantages of the present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, in which:
For solving the drawbacks encounter from the prior art, the present invention provides a multi-function mouse device.

The computer system 4 comprises a computer host 41 and a computer monitor 42. The computer host 41 is in communication with the multi-function mouse device 3 and the computer monitor 42. A cursor 421 and a graphic-based window 422 are displayed on the computer monitor 42. In this embodiment, the graphic-based window 422 is illustrated by referring to a graphic-based window of a web browser, but is not limited thereto.
In this embodiment, a backspace function is implemented in response to the execution of the first predetermined command, and the predetermined distance is a near-zero distance. Consequently, even if the user presses and triggers the mode selection element 32 of the multi-function mouse device 3 without moving the casing 30, a backspace action is performed on the graphic-based window 422 that is displayed on the computer monitor 42. For example, while keying in the web browser, the backspace action may be performed. However, those skilled in the art will readily observe that numerous modifications and alterations may be made while retaining the teachings of the invention. For example, in a variant example, a delete function is implemented in response to the execution of the first predetermined command.
If a single displacement amount signal including only an X-axis direction moving vector is received by the controlling unit 33 in response to the movement of the casing 30 and a magnitude of the X-axis direction moving vector is higher than a first threshold value, the controlling unit 33 judges that the motion trajectory of the casing 30 is the linear motion trajectory in the X-axis direction. For example, the linear motion trajectory in the X-axis direction includes a motion trajectory Z1 or a motion trajectory Z2, wherein the motion trajectory Z1 and the motion trajectory Z2 are opposed to each other. In this embodiment, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z1, the predetermined command is executed by the computer host 41 to implement a “Backward” function of a web browser. In addition, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z2, the predetermined command is executed by the computer host 41 to implement a “Forward” function of the web browser. However, those skilled in the art will readily observe that numerous modifications and alterations may be made while retaining the teachings of the invention.
Moreover, if a single displacement amount signal including only a Y-axis direction moving vector is received by the controlling unit 33 in response to the movement of the casing 30 and a magnitude of the Y-axis direction moving vector is higher than a second threshold value, the controlling unit 33 judges that the motion trajectory of the casing 30 is the linear motion trajectory in the Y-axis direction. For example, the linear motion trajectory in the Y-axis direction includes a motion trajectory Z3 or a motion trajectory Z4, wherein the motion trajectory Z3 and the motion trajectory Z4 are opposed to each other. In this embodiment, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z3, the predetermined command is executed by the computer host 41 to implement a function of opening a web browser software (e.g. an Internet Explorer software). In addition, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z3, the predetermined command is executed by the computer host 41 to implement a screen-locking function. However, those skilled in the art will readily observe that numerous modifications and alterations may be made while retaining the teachings of the invention.
If a single displacement amount signal including an X-axis direction moving vector and a Y-axis direction moving vector is received by the controlling unit 33 in response to the movement of the casing 30 and a magnitude of the X-axis direction moving vector is higher than the first threshold value and a magnitude of the Y-axis direction moving vector is higher than the second threshold value, the controlling unit 33 judges that the motion trajectory of the casing 30 is the linear motion trajectory in the specified direction between the X-axis direction and the Y-axis direction. For example, the linear motion trajectory in the specified direction between the X-axis direction and the Y-axis direction includes a motion trajectory Z5, a motion trajectory Z6, a motion trajectory Z7 or a motion trajectory Z8.
For example, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z5, the predetermined command is executed by the computer host 41 to implement a zooming out function. Moreover, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z6, the predetermined command is executed by the computer host 41 to implement a zooming in function. Moreover, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z7, the predetermined command is executed by the computer host 41 to implement a function of closing an application program (e.g. a function of closing an Internet Explorer software). Moreover, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the motion trajectory Z8, the predetermined command is executed by the computer host 41 to implement a CapsLock function. However, those skilled in the art will readily observe that numerous modifications and alterations may be made while retaining the teachings of the invention.
Moreover, plural displacement amount signals (e.g. a first displacement amount signal, a second displacement amount signal and a third displacement amount signal) may be sequentially received by the controlling unit 33 in response to the movement of the casing 30. If the X-axis (Y-axis) direction moving vector of the second displacement amount signal is opposed to the X-axis (Y-axis) direction moving vector of the first displacement amount signal and the X-axis (Y-axis) direction moving vector of the third displacement amount signal, and if the magnitude of the X-axis (Y-axis) direction moving vector of the first displacement amount signal, the magnitude of the X-axis (Y-axis) direction moving vector of the second displacement amount signal and the magnitude of the X-axis (Y-axis) direction moving vector of the third displacement amount signal are all higher than a predetermined threshold value, the controlling unit 33 judges that the motion trajectory of the casing 30 is a reciprocating motion trajectory (a Z letter-shaped motion trajectory). For example, the reciprocating motion trajectory includes a motion trajectory Z9, a motion trajectory Z10 or a motion trajectory Z11. In this embodiment, if the controlling unit 33 judges that the motion trajectory of the casing 30 is the reciprocating motion trajectory, the predetermined command is executed by the computer host 41 to implement an Enter function. However, those skilled in the art will readily observe that numerous modifications and alterations may be made while retaining the teachings of the invention.
By the way, when the casing 30 is moved, the casing 30 is usually unable to be accurately moved in the linear direction. That is, the motion trajectory of the casing 30 may be slightly shifted. Preferably, after the magnitude of the X-axis direction moving vector and the magnitude of the Y-axis direction moving vector of the received displacement amount signal are analyzed by the controlling unit 33 of the multi-function mouse device 3, the controlling unit 33 can realize the anticipated motion trajectory of the casing 30 according to the proportion of the magnitude of the X-axis direction moving vector to the magnitude of the Y-axis direction moving vector. For example, if the magnitude of the X-axis direction moving vector and the magnitude of the Y-axis direction moving vector of the displacement amount signal received by the controlling unit 33 are 10 mm and 5 mm, respectively, the controlling unit 33 may judge that the displacement amount signal including only the X-axis direction moving vector is received. Consequently, the shifted motion trajectory of the casing 30 will not cause erroneous operation of the multi-function mouse device 3.
From the above descriptions, by judging whether the motion trajectory of the casing 30 reaches the predetermined distance after the mode selection element 32 is triggered, the controlling unit 33 may determine whether the operating mode of the multi-function mouse device 3 or 3′ needs to be switched. In comparison with the conventional mouse device of
Moreover, since a small memory space is required to store various predetermined moving trajectories and corresponding predetermined commands, the predetermined moving trajectories and the corresponding predetermined commands may be stored in a memory of the controlling unit 33. Consequently, the multi-function mouse device can provide various functions without the need of installing a driver in the computer host 41.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
