Continuous Input Mode for Pointing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pointing devices, such as mice, trackballs, and touchpads, often result in syncopated or non-continuous movement of pointer images or virtual environments due to limited movement areas, requiring users to lift and reposition the device for extended movement, leading to discontinuous input.
Innovation Solution
Implementing a continuous input mode where a vector signal from the pointing device is transmitted repetitively when a command signal is activated, allowing for continuous movement of the pointer image or virtual environment even after the device's movement has stopped, by using a combination of vector and command signals to maintain the desired direction and magnitude of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pointing devices are used with limited movement areas, then the device structure remains simple and portable, but the movement of pointer image becomes syncopated and non-continuous
Solution Approach 1:
The patent implements continuous input mode where the pointing device transmits vector signals repetitively until a command signal is received, allowing the pointer image to move continuously without requiring the user to lift and reposition the device. This resolves the contradiction by maintaining simple device structure while achieving continuous movement through signal repetition mechanism.
2Length of moving object
If the pointing device movement area is limited, then the device remains portable and easy to use, but extended movement requires lifting and repositioning the device
Solution Approach 1:
The patent uses periodic repetition of vector signals to extend the effective movement range. When in continuous input mode, the pointing device sends vector signals repeatedly at regular intervals, allowing the pointer image to continue moving in the same direction without requiring physical movement of the device. This enables extended movement range while maintaining ease of operation.
3Productivity
If vector signals are transmitted repeatedly in continuous input mode, then seamless movement of pointer image is achieved, but signal transmission frequency increases
Solution Approach 1:
The patent implements dynamic signal transmission where the frequency and continuity of vector signal transmission adapts to user needs. In continuous input mode, signals are transmitted repeatedly to maintain movement, while in normal mode, signals are transmitted only when needed. This dynamic adjustment optimizes productivity by enabling seamless movement when required while reducing unnecessary signal transmission energy consumption.

AI summary
A system and method for providing a continuous input mode is disclosed. In the continuous input mode, a combination of a vector signal and a command signal is received from an input device. Upon receipt of a vector signal and a command signal, an image is moved on a display screen, for example. The image continues to move until the command signal is terminated. If a new vector signal is received prior to termination of the command signal, then the direction of image movement may be changed and will occur until termination of the command signal. Additional aspects of the present invention relate to input devices and computer-readable media with computer executable instructions utilized in switching between the input modes.
