This invention relates generally to user interfaces, and more particularly to cursor control on user interfaces suitable for mobile environments.
Although the concept of attractive links for computing devices is known, the existing techniques fail to optimize the overall user experience based on actual environmental conditions. In one scheme, the attractive link function is used to improve a user's unstable hand input, but fails to take into account the motion the user may be experiencing in their environment. The function is user selectable and no monitoring of the environmental conditions appears to be done. In another technique, an in-car computing device provides cursor control, but without the further refinements that makes for an optimized user experience. In other schemes, forces are applied on a mouse, trackball, or other similar user input devices to provide repelling functions or force feedback to a user operating a user input.
Embodiments in accordance with the present invention can provide a method and device that automatically applies an attraction function on a cursor based on a combination of proximity to a display element or hyperlink and further based on motion sensing. Other embodiments can use and enhance the attraction function by introducing time delays to prevent unwanted movement, adjust pull rates toward a link or object, and/or by further monitoring a motion sensor such as an accelerometer to enable, disable, or adjust the attraction function.
In a first embodiment of the present invention, a method of attractive linking to an object such as a hyperlink on a user interface can include the steps of detecting a predetermined proximity of a cursor to an object, applying an attraction function to the cursor causing the cursor to move towards the object (optionally at an increased rate), and applying a delay function reducing further movement of the cursor once the cursor is within another predetermined proximity of the object. The method can further include the step of monitoring a motion sensor and adjusting the attraction function based on a motion sensor reading. The method can further include the step of adjusting the delay and/or attraction functions based on a motion sensor reading. The method can further include monitoring an accelerometer and applying the attraction function to the cursor when the accelerometer detects motion of a predetermined threshold or characteristic. Accordingly, the attraction function to the cursor can be turned off when the accelerometer fails to detect motion of the predetermined threshold or characteristic. The method can further include the step of providing a second cursor that operates as a shadow function of the cursor. In one embodiment, the second cursor can be operated solely through user input.
In a second embodiment of the present invention, a portable electronic device such as cellular phone, a laptop computer, a personal digital assistant, a smart phone or a two-way radio can include a display operable to present a cursor and an object or a displayed element, a cursor control, and a processor coupled to the display and cursor control and capable of detecting a position of the cursor. The processor can be operable to detect a predetermined proximity or a predetermined threshold distance between the cursor and the object or displayed element, apply an attraction function to the to the cursor causing the cursor to move towards the object (optionally at an increased rate), and (in this embodiment) apply a delay function reducing further movement of the cursor once the cursor is within another predetermined proximity or threshold distance of the object or displayed element. The processor can be further programmed to adjust the attraction and/or delay functions based on a motion sensor reading. The motion sensor can be an accelerometer and the processor can be further programmed to monitor the accelerometer and apply the attraction function to the cursor when the accelerometer detects motion of a predetermined threshold or characteristic. The processor can be further programmed to turn off the attraction function to the cursor when the accelerometer fails to detect motion of the predetermined threshold or characteristic. The processor can be further programmed to provide a second cursor that operates as a shadow function of the cursor where the second cursor optionally solely operates though user input.
In a third embodiment of the present invention, a portable electronic device can include a display operable to present a cursor and an object (such as a hyperlink) to a user, a cursor control, a motion sensor for detecting motion of the device, and a processor coupled to the display, the cursor control, and motion sensor. The processor can be operable to detect a predetermined proximity or a predetermined distance threshold between the cursor and the object, apply an attraction function to the cursor causing the cursor to accelerate towards the object when the cursor is within the predetermined threshold distance, and adjust the attraction function for the cursor responsive to an output of the motion sensor. The processor can be further programmed to apply the delay function reducing further movement of the cursor once the cursor is within another predetermined proximity of the object or hyperlink. The portable electronic device can further include an accelerometer as the motion sensor and the processor is further programmed to monitor the accelerometer and apply the attraction function to the cursor when the accelerometer detects motion of a predetermined threshold or characteristic and further programmed to turn off the attraction function to the cursor when the accelerometer fails to detect motion of the predetermined threshold or characteristic. The processor can be further programmed to provide a second cursor that operates as a shadow function of the cursor solely using user input. A “motion sensor” can be any device that detects motion and is not necessarily limited to an accelerometer or a tilt switch. Detecting motion of a predetermined threshold or characteristic can mean detection of a pattern of motion that can be expected in a vehicle and can also simply mean detection of a non-stationary environment.
The terms “a” or “an,” as used herein, are defined as one or more than one. The term “plurality,” as used herein, is defined as two or more than two. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and/or “having,” as used herein, are defined as comprising (i.e., open language). The term “coupled,” as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically. The term “proximity” as used herein can be mean within a predetermined border of an object or within a particular distance of an object. An “attraction function” can be a function that causes the cursor to move towards an object at a quicker rate than normal and can also include moving the cursor to the object instantaneously once the cursor reaches a predetermined border or distance from the object. The term “cursor” generally indicates where to place a user input. The term “hyperlink” is a link in a document or some other source to information within that document or the other source. These links are usually represented by highlighted words or images. When a user selects a hyperlink, a display switches to the portion referenced by the hyperlink. The term “displayed element” can be any displayed object including, but not limited to a hyperlink or other objected effected by a user input.
The terms “program,” “software application,” “resizing program” and the like as used herein, are defined as a sequence of instructions designed for execution on a computer system. A program, computer program, or software application may include a subroutine, a function, a procedure, an object method, an object implementation, an executable application, an applet, a servlet, a source code, an object code, a shared library/dynamic load library and/or other sequence of instructions designed for execution on a computer system.
Other embodiments, when configured in accordance with the inventive arrangements disclosed herein, can include a system for performing and a machine readable storage for causing a machine to perform the various processes and methods disclosed herein.
While the specification concludes with claims defining the features of embodiments of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the figures, in which like reference numerals are carried forward.
Embodiments herein can be implemented in a wide variety of ways using a variety of technologies that enable precise or assisted positioning of cursors in environments where such precision is difficult to obtain consistently.
