Solution Overview
Problem
Existing touch input devices face challenges in accurately inputting characters while reducing error rates and improving user experience, especially when users need to look at the screen during input.
Innovation Solution
A touch input device with a swiping input unit and a gesture input unit, where the swiping input unit is positioned on the edge and the gesture input unit is centered, allowing users to input characters through swiping gestures, with a controller determining the input character based on gestures between these units, and a display device for highlighting selected characters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a touch input device uses a single integrated touch area for character input, then the device structure is simple, but the user cannot easily distinguish different input zones leading to input errors
Solution Approach 1:
The touch input device divides the touch-sensitive surface into distinct functional zones: a swiping input unit for selecting characters and a gesture input unit for confirming input. This segmentation allows users to clearly distinguish between different input operations, reducing input errors while maintaining a relatively simple overall structure.
Solution Approach 2:
Different regions of the touch input device are assigned different functional qualities - the swiping input unit responds to directional swipe gestures for character selection, while the gesture input unit responds to tap or press gestures for confirmation. This local differentiation of quality enables precise input without requiring complex additional components.
2Productivity
If the touch input device requires users to look at the input unit for accurate input, then input accuracy improves, but the user cannot look at the screen simultaneously reducing productivity
Solution Approach 1:
The touch input device provides tactile feedback through distinct tactile sensations in different zones - the swiping input unit offers directional guidance through its tactile properties, and the gesture input unit provides confirmation through its tactile response. This self-service tactile guidance allows users to operate the device accurately while watching the screen, improving both productivity and maintaining input accuracy.
3Ease of operation
If the touch input device uses only swiping gestures for character selection, then the interface is simple, but users lack tactile feedback reducing ease of operation
Solution Approach 1:
The device segments the touch input surface into zones with different tactile characteristics. The swiping input unit provides tactile guidance for directional input, while the gesture input unit provides distinct tactile feedback for confirmation. This segmentation enhances ease of operation through tactile feedback without requiring complex mechanical components, as the tactile differentiation is achieved through the touch-sensitive surface design.

AI summary
A touch input device and control method thereof, wherein the touch input device includes a swiping input unit configured to receive a selection of a character through a swiping gesture by a user, a gesture input unit placed on an area different from that of the swiping input unit and in which a user inputs a gesture trough a touch, and a controller configured to determine that the selected character is input when a touch gesture is input from the swiping input unit to the gesture input unit.
