Touch Interface Deletion Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deleting user interface objects on touch-sensitive devices are cumbersome and inefficient, often requiring multiple steps and risking accidental deletion due to the complexity of the interaction process.
Innovation Solution
A method that utilizes a combination of visual, audible, and tactile feedback mechanisms to simplify the deletion process by providing initial feedback upon prolonged touch, increasing feedback intensity, and confirming deletion with a final feedback signal, allowing for gradual removal of the object from the interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing deletion methods are used to prevent erroneous deletion, then deletion safety is improved, but the number of interaction steps increases and efficiency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the system provides visual feedback (highlighting the object) and haptic feedback (vibration patterns) to the user during the deletion process. The vibration intensity and pattern change based on the duration of the touch input, providing real-time feedback about the deletion state without requiring additional interaction steps, thus maintaining safety while improving efficiency.
Solution Approach 2:
The system performs preliminary actions by automatically highlighting the target object and providing initial vibration feedback as soon as the touch input is detected. This preliminary feedback prepares the user for the upcoming deletion without requiring separate confirmation steps, reducing the total interaction time while maintaining safety through progressive feedback.
2Measurement precision
If multiple interaction steps are required for deletion, then accuracy of deletion intent is improved, but cognitive burden increases and user experience deteriorates
Solution Approach 1:
The system dynamically adjusts the vibration feedback characteristics based on the duration of the touch input. During the first time period, a first vibration pattern is provided, and during the second time period, a second vibration pattern with different intensity or pattern is provided. This dynamic feedback helps users understand the deletion progress and intent accuracy without requiring multiple discrete interaction steps.
Solution Approach 2:
The deletion process maintains continuous useful action by providing uninterrupted haptic and visual feedback throughout the entire deletion sequence. The feedback continues from the initial touch through the deletion confirmation, eliminating gaps where users might lose track of the deletion state, thereby improving both accuracy and ease of operation.
3Loss of information
If feedback intensity is increased to signal forthcoming deletion, then user awareness is improved, but potential for user distraction or anxiety increases
Solution Approach 1:
The system uses periodic vibration patterns to provide feedback about the deletion process. The vibration occurs in controlled intervals during the touch duration, providing sufficient awareness without continuous intense stimulation. This periodic feedback maintains user awareness while avoiding excessive distraction or anxiety.
Solution Approach 2:
The system changes vibration parameters (intensity, frequency, pattern) based on the deletion stage and user interaction duration. During the first time period, one set of vibration parameters is used, and during the second time period, different parameters are applied to signal the forthcoming deletion. This parameter adjustment provides necessary awareness while minimizing harmful distraction effects.
