Touch Screen Protection Area for Digital Camera Grip Malfunctions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital photographing apparatuses with large touch screens face issues with touch malfunctions when held, as the hand used to grip the device can inadvertently press icons on the screen, leading to unstable operation and malfunctions.
Innovation Solution
Incorporating a touch protection area on the touch screen that is not activated by user input, allowing users to set and adjust its size and location to prevent accidental touches, thereby preventing malfunctions during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large-sized touch screen is installed to display more vivid images, then the display quality is improved, but the grip area is reduced making it difficult to hold the device
Solution Approach 1:
The touch screen is divided into two distinct zones: a touch area for user interaction and a touch protection area that prevents accidental inputs. This segmentation allows the display to maintain its large size for vivid image display while designating specific regions that will not respond to touches, effectively creating a non-interactive grip zone that prevents malfunctions during handling.
2Adaptability or versatility
If a large-sized touch screen is installed to provide user convenience, then the display functionality is improved, but touch malfunctions occur when the hand covers the screen during gripping
Solution Approach 1:
Different regions of the touch screen are assigned different functional qualities. The touch area maintains full interactivity for user operations, while the touch protection area is configured with a non-responsive quality that prevents it from activating icons or functions. This local differentiation ensures that gripping the device with the hand covering part of the screen does not cause accidental inputs or malfunctions.
3Reliability
If the touch protection area is added to prevent accidental touches, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The touch protection area is designed to be dynamically configurable rather than fixed. Users can arbitrarily set the size, shape, and location of the protection area according to their specific gripping habits and device usage patterns. This dynamic adaptability allows the system to maintain high reliability by preventing accidental touches while keeping the control logic relatively simple through user-defined parameters.

AI summary
A digital photographing apparatus and a method of controlling the digital photographing apparatus prevent a touch malfunction from occurring while holding the digital photographing apparatus by having a touch protection area in the digital photographing apparatus. The digital photographing apparatus includes a large-sized touch screen on one surface thereof, wherein the touch screen includes: a touch area which inputs a touch from a user and executes icons corresponding to the touch; and a touch protection area which is not activated by the touch when the touch from the user is input on the touch screen.
