Clamshell Notebook Palm Rest Sensors for Keyboard Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices with both touch screens and keyboards often experience unintentional data input due to accidental key presses when trying to use the touch screen, necessitating a more efficient method to prevent erroneous inputs.
Innovation Solution
The implementation of sensors in palm rest areas to detect the presence of a user's body parts, automatically enabling or disabling the keyboard to prevent accidental key presses, allowing users to input data without manually locking and unlocking the keyboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual keyboard lock operation is used, then accidental key presses are prevented, but user operation becomes cumbersome requiring manual activation and deactivation
Solution Approach 1:
The system automatically detects when the user's hands are on the palm rest areas using sensors and autonomously enables or disables the keyboard accordingly, eliminating the need for manual lock/unlock operations while maintaining reliable prevention of accidental key presses
Solution Approach 2:
The system continuously monitors the palm rest areas for user presence using sensors and dynamically adjusts keyboard functionality based on real-time detection, creating a closed-loop control system that automatically responds to user actions
2Ease of operation
If keyboard is always enabled, then ease of use is maximized, but accidental inputs occur when using touch screen
Solution Approach 1:
The keyboard functionality dynamically changes state based on real-time detection of user hand positions on the palm rest areas, transitioning between enabled and disabled states to adapt to different usage scenarios and prevent accidental inputs while maintaining accessibility when needed
Data Source
AI summary
An input device and computing system is provided for a user to input data. An input device may comprise a plurality of input keys, palm rest areas, and a touchpad. The palm rest areas may have a first palm rest area and a second palm rest area with each palm rest area includes a sensor configured to detect a body part of a user. A first sensor may be used for detecting a presence of a first body part of a user. A second sensor may be for detecting a presence of a second body part of a user, such as the left hand of the user. A touchpad may be disposed between the first sensor and the second sensor.
