Adaptive Touch-and-Hold Activation for Fewer False Triggers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue with bezel-less screens is that touch and hold operations for activating functions, such as voice assistants, can be inconvenient due to fixed duration settings leading to excessive waiting or accidental activation, affecting user experience.
Innovation Solution
An electronic device dynamically adjusts the duration of a touch and hold operation based on the frequency of function usage, shortening for high-frequency users and lengthening for low-frequency users to improve accuracy and prevent accidental activations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed duration is set for touch and hold operation, then the operation is simple to implement, but the user experience deteriorates due to excessive waiting time or accidental activation
Solution Approach 1:
The patent applies dynamics by making the touch and hold duration adjustable rather than fixed. The system dynamically modifies the required hold duration based on detected usage patterns, transitioning from a static parameter to a dynamic one that adapts to user behavior, thereby resolving the contradiction between operational simplicity and activation accuracy
Solution Approach 2:
The patent implements feedback by monitoring whether the activated function is actually used after each touch and hold operation. This feedback loop allows the system to learn from user behavior and adjust the touch and hold duration accordingly, improving reliability while maintaining ease of operation through adaptive optimization
2Reliability
If the touch and hold duration is set to be long, then accidental activation is reduced, but the user experiences excessive waiting time when needing to use the function
Solution Approach 1:
The system dynamically adjusts the touch and hold duration based on learned usage patterns. For frequently used functions, the duration is shortened to reduce waiting time, while for rarely used functions, it is lengthened to prevent accidental activation, thus resolving the time-reliability trade-off
Solution Approach 2:
The patent changes the parameter of touch and hold duration from a fixed value to a variable that is continuously adjusted based on usage frequency. This parameter adaptation allows the system to optimize both activation speed and accuracy by modifying the duration parameter according to actual user needs
3Loss of time
If the touch and hold duration is set to be short, then quick activation is achieved, but accidental activation increases affecting user experience
Solution Approach 1:
The system makes the touch and hold duration dynamic, shortening it for frequently accessed functions to enable quick activation, while automatically lengthening it for rarely used functions to prevent accidental triggers, thus achieving both speed and reliability
Solution Approach 2:
The patent implements parameter changes by adjusting the touch and hold duration based on usage frequency data. The system modifies this critical parameter to optimize the balance between activation speed and accidental prevention, improving overall user experience
4Device complexity
If a fixed duration is used for all functions, then the system is simple to manage, but it cannot adapt to individual usage habits of different users
Solution Approach 1:
The system applies self-service by automatically monitoring usage patterns and adjusting touch and hold durations without requiring user configuration. The device learns from user behavior and autonomously optimizes the parameters, maintaining simplicity while achieving adaptability to individual habits
Solution Approach 2:
The patent uses feedback mechanisms to track whether functions are actually used after activation. This feedback enables the system to adapt to individual user habits by identifying frequently and rarely used functions, automatically customizing the touch and hold duration for each user without increasing management complexity

AI summary
This application discloses a function enabling method, a user interface, and an electronic device. In the method, the electronic device may determine, based on a record of whether a user uses a first function after the user enables the first function by using a touch and hold operation a plurality of times, a frequency of using the first function by the user, so that trigger duration required by the touch and hold operation when the touch and hold operation triggers to enable the first function is dynamically adjusted. In this way, when the first function is used at a high frequency, the electronic device may shorten the trigger duration of the touch and hold operation, to prevent the user from waiting for excessively long time when the user enables the first function. When the first function is used at a low frequency, the electronic device may prolong the trigger duration of the touch and hold operation, to reduce a probability that the user mistakenly enables the first function.
