Visual Indication for Touch Input Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in providing users with clear visual indications of intended operations before execution, leading to confusion and inefficiency due to the small screen size and complexity of user inputs, where users may inadvertently apply inputs in the wrong location or manner.
Innovation Solution
The system provides a visual indication of the operation to be executed by using a graphical effect on the screen based on the position of the user's input, simulating a physical response, such as deflection or transition, to help users verify the correct input location and intent before the operation is performed.

Engineering Contradiction Analysis
1Weight of moving object
If the screen size is made small to enable portability, then the device becomes more portable, but the user cannot clearly verify the input location and intended operation
Solution Approach 1:
The system performs a preliminary visual indication action before the actual operation execution. When the user contacts the screen, the system first displays a visual indication (such as a highlighted region or graphical effect) showing where the operation will be applied, allowing the user to verify the input location before the operation is executed. This preliminary feedback mechanism compensates for the limited screen real estate by providing clear, immediate visual confirmation of the intended operation area.
2Ease of operation
If the user input mechanism is made simple for ease of use, then the operation is easier to perform, but the user cannot distinguish between different operations that may result from the same input
Solution Approach 1:
The system provides immediate visual feedback in the form of a visual indication that appears when the user makes contact with the screen. This feedback shows the user exactly which operation will be executed based on the contact position and pattern, allowing the user to understand the distinction between different operations (such as swipe direction, pressure level, or location-based operations) before they are executed. This feedback loop maintains ease of use while providing necessary operational clarity.
3Loss of information
If the visual indication is provided immediately upon contact to show the intended operation, then the user can verify the operation before execution, but the indication must be displayed quickly on a small screen
Solution Approach 1:
The system utilizes color changes and graphical effects to provide the visual indication. When the user contacts the screen, the system rapidly changes the color or displays a graphical effect at the contact location or in the intended operation area. This visual indication appears immediately, providing the user with verification of the intended operation before execution. The use of color and graphical effects allows for rapid, clear communication of operational intent on the small screen without requiring additional time or space.

AI summary
An apparatus, method, and computer program product are described that provide for a visual indication of an operation to be performed, such that a user, upon applying a first portion of a user input, may be able to determine from the visual indication whether the input applied, when completed, will cause the desired operation to be performed. The apparatus may provide for the display of a screen having a representation of interactive content, and an input may be received from the user that includes a contact component and a movement component, such as a stroke gesture. In response to receipt of the contact component and prior to receipt of the movement component, the apparatus may provide for a visual indication of an operation to be performed. The operation may be executed based on receipt of at least a portion of the movement component.
