Palm Touch Control for Electronic Device Privacy and Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require time and are not intuitive to control settings like volume and screen brightness, especially in situations where privacy is needed, as users often inadvertently turn off the screen or reduce volume for others, affecting both themselves and others around them.
Innovation Solution
An electronic device with a touch sensor that detects a palm touch to control outputs such as volume, brightness, and screen display area without the need for a separate function key, allowing rapid adjustments by determining the touch area and changing settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a user covers the screen with their hand to protect privacy, then other people cannot view the screen, but the user also cannot view the screen
Solution Approach 1:
The screen display area is segmented into different regions based on palm touch detection. When a palm touch is detected, the display area is partially turned off in the region corresponding to the palm touch location, allowing the user to protect privacy in specific areas while maintaining screen functionality in other regions.
Solution Approach 2:
The palm touch itself serves as an intermediary mechanism between the user's privacy protection need and the screen display system. By detecting the palm touch and using it as control input, the system enables the user to adjust display settings intuitively without requiring separate controls, thus maintaining screen accessibility while protecting privacy.
2Object-affected harmful factors
If the user turns off the screen or reduces volume for others in public places, then inconvenience to others is decreased, but the user loses control over their own device settings
Solution Approach 1:
The palm touch detection system enables self-service control of device settings. The user's natural palm touch action directly controls the display area and volume settings, eliminating the need to search for separate function keys or buttons, thus maintaining ease of operation while achieving the goal of reducing inconvenience to others.
Solution Approach 2:
The traditional mechanical button-based control system is replaced with a touch-based control system that detects palm touches. This substitution allows for more intuitive and rapid control of settings like volume and display area, improving ease of operation while enabling the user to quickly adjust settings to reduce inconvenience to others in public places.
3Measurement precision
If the user uses traditional key input to control settings, then precise control is achieved, but time is required to find and press the correct key
Solution Approach 1:
The control interface is extended from traditional one-dimensional button pressing to two-dimensional touch area detection on the screen surface. By detecting the location and area of palm touches, the system provides precise control of settings such as display area and volume, while significantly reducing the time required compared to searching for and pressing specific function keys.

AI summary
A method and an apparatus for controlling an electronic device is provided. The method and an apparatus for operating a function by detecting a touch area in which a touch is input by a user in an electronic device capable of receiving a touch input are provided. A method of controlling an electronic device includes detecting a touch inputted to the electronic device, determining whether the touch is a palm touch based on information related to the touch, and when the touch is determined to be the palm touch, controlling an output of data provided by the electronic device based on a change in a palm touch area of the palm touch.
