Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods of providing haptic feedback in electronic devices with touch-sensitive surfaces are not as effective as they could be, leading to inefficiencies in user interactions.
Innovation Solution
Implementing improved methods and interfaces for haptic feedback that reduce the number, extent, and nature of user inputs by generating tactile outputs in response to specific movement thresholds and gestures on touch-sensitive surfaces, often combined with visual and audio feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional haptic feedback methods are used, then basic tactile output is provided, but user understanding of input-device interactions is insufficient leading to errors and inefficiency
Solution Approach 1:
The patent implements enhanced haptic feedback mechanisms that provide tactile output in response to specific input conditions, movement thresholds, and gestures. This feedback loop helps users understand the connection between their inputs and device responses, reducing errors and improving interaction efficiency by making the system's state and response criteria more perceptible to the user
2Loss of information
If more haptic feedback is provided to improve user understanding, then the number and complexity of system components increases
Solution Approach 1:
The patent applies partial action by providing haptic feedback selectively based on specific conditions, movement thresholds, and gesture types rather than continuously. This approach improves user understanding of critical interactions while avoiding unnecessary feedback that would increase system complexity and input requirements

AI summary
An electronic device displays a user interface including a slider control that represents a continuous range of values between a first value and a second value, the slider control includes a first end that corresponds to the first value and a second end that corresponds to the second value, and the slider control further includes a movable indicator configured to move along the slider control between the first and the second end. The device detects a contact on the slider control followed by a movement of the contact. In response to the movement detection, the device moves the moveable indicator along the slider control and generates a tactile output upon the moveable indicator reaching the first end of the slider control with a tactile output pattern configured based on a movement speed when the moveable indicator reaches the first end.
