Handheld Air Mouse Cursor Speed Control for Fine Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air mouse devices require visual attention for data entry and cursor control, making them uncomfortable and inefficient, especially when transitioning between fast and slow movements, and they cannot combine air mouse and data entry functions without dividing user attention from the screen.
Innovation Solution
A hand-held electronic device with an air mouse unit that includes a touch sensor and processor for controlling cursor speed and switching between air mouse and touch-pad modes, allowing for ergonomic design and data entry without visual attention, using a deflection control unit and displacement sensors for precise cursor control and click functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an air mouse device includes a touch screen for data entry and cursor control, then data entry functionality is improved, but user attention is divided from the main display screen reducing efficiency
Solution Approach 1:
The patent extracts the data entry interface from the main display screen and relocates it to the hand-held device's display. This allows users to enter data on the portable device while viewing the main screen content, eliminating the need to divide attention between multiple surfaces and enabling continuous monitoring of the primary display during data entry operations.
Solution Approach 2:
The hand-held device serves as an intermediary between the user and the main system. It provides a separate data entry interface that communicates with the host system, allowing users to input data without directly interacting with the main display screen, thus maintaining focus on the primary display while enabling data entry functionality.
2Speed
If cursor speed is increased for fast movements across the screen, then navigation efficiency is improved, but fine control near target areas becomes difficult
Solution Approach 1:
The patent implements dynamic cursor speed control where the cursor movement speed automatically adjusts based on the distance to the target. When the cursor is far from the target, it moves at high speed for efficient navigation. As the cursor approaches the target area, the speed automatically reduces to enable precise positioning and fine control, eliminating the need for manual speed adjustment by the user.
3Adaptability or versatility
If the device supports both air mouse and touch-pad modes, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic mode switching where the operating mode (air mouse or touch-pad) automatically changes based on detected hand movement characteristics. The system analyzes the stability and movement patterns of the hand-held device and seamlessly transitions between modes without requiring manual intervention from the user, simplifying the user interface while maintaining multiple operational capabilities.

AI summary
A hand held electronic device (10) including an air mouse unit for communicating with a remote host device (30) having a display screen (32) on which a cursor is displayed, wherein during operation as an air mouse the movement of the device controls the movement of the cursor, the device comprises an elongated body (11) with different surface regions accessible by a finger of the holding hand, and in one accessible surface region has a control field (35, 36), and a touch sensor (23, 24) is arranged under the control field (35, 36) that senses when the control field (35, 36) is touched by the finger and when the finger is moved thereon, and the air mouse unit has a deflection control unit (27) controlling the speed of the cursor movement in response to a unity movement of the device, and a processor (43) is connected to the touch sensor (23, 24) that controls the deflection control unit (27) to increase or decrease the speed of the cursor control in response to a predetermined first finger movement. The device can be complemented with a direct data entry function using a different surface region and with a conventional mouse function using a further different region.
