Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld electronic devices require complex hand postures for controlling digital information frame operations such as enlargement, reduction, and rotation, making them inconvenient to use.
Innovation Solution
A handheld electronic device comprising a display module, a detection module, and a processing module that detects single or double touches and motion tracks to perform preset actions like frame reduction, enlargement, rotation, and switching based on duration time and graphic recognition, allowing for simple control using one or two fingers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional touch control methods are used for frame operations, then the device can perform frame enlargement, reduction, and rotation, but users must adopt complicated different hand postures which reduces ease of operation
Solution Approach 1:
The patent changes the control parameters from complex hand postures to simple touch duration and motion track parameters. By detecting whether a touch duration exceeds a threshold or a motion track matches a preset graphic, the system achieves frame operations with simpler user interactions, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The patent replaces complex mechanical hand posture requirements with a simplified touch detection system that measures duration and motion tracks. This substitution allows the device to interpret user intentions through basic touch patterns rather than requiring sophisticated hand positioning, thereby improving ease of operation while maintaining functional capability
2Ease of operation
If simple touch control is implemented, then ease of operation is improved, but the precision of frame control operations may be compromised
Solution Approach 1:
The patent incorporates feedback mechanisms where the system continuously monitors touch duration and motion track during the interaction. This feedback allows the system to distinguish between intentional frame control actions and accidental touches by comparing detected parameters against preset thresholds and graphics, thereby maintaining measurement precision while preserving ease of operation
Solution Approach 2:
The patent employs preliminary detection of touch patterns before executing frame operations. By pre-establishing threshold values and preset graphics for motion tracks, the system prepares criteria for valid operations in advance, ensuring that only precise and intentional actions trigger the desired frame control functions

AI summary
A handheld electronic device and a frame control method of digital information thereof. The handheld electronic device comprises a display module, a detection module and a processing module. The display module is used to display the digital information. The detection module is connected to the display module and used to detect whether the display module is touched by a predetermined method and also used to detect a duration time or a motion track when the display module is touched by the predetermined method. The processing module is connected to the display module and the detection module and determines whether the duration time exceeds a threshold value or the motion track corresponds to a preset graphic. When the duration time exceeds the threshold value or the motion track corresponds to the preset graphic, the processing module would execute a preset process action of the digital information.
