Touch-Screen Control With Selective Vibration Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote control of imaging apparatuses via touch operations on information terminals lacks feedback, leading to uncertain operation results and potential deterioration in operability, especially during continuous setting changes like zooming.
Innovation Solution
An information processing apparatus and method that includes a touch-screen capable of detecting touches, with a processor executing instructions to display a predetermined shape area, detect touch-slide operations, change setting values accordingly, and control vibrations based on the type of setting item assigned to the area, providing feedback only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vibration feedback is provided during touch-slide operations to improve operability, then user feedback is enhanced, but unnecessary vibration occurs during continuous setting changes like zooming
Solution Approach 1:
The patent applies different vibration feedback strategies to different setting items. Discontinuous setting items (e.g., aperture, shutter speed) receive vibration feedback when their values change, while continuous setting items (e.g., zoom) do not receive vibration feedback during their adjustment. This localized differentiation resolves the contradiction by providing feedback only where needed.
Solution Approach 2:
The patent dynamically adjusts the vibration feedback behavior based on the type of setting item being modified. The system identifies whether a setting item changes discretely or continuously and adapts the vibration feedback accordingly, enabling or disabling vibration based on the operational context rather than using a fixed feedback strategy.
2Loss of information
If vibration feedback is provided for every setting change, then user awareness of setting changes is improved, but operability deteriorates due to constant vibration during continuous operations
Solution Approach 1:
The patent implements selective vibration feedback based on the specific setting item being adjusted. Information feedback (vibration) is provided locally only for discontinuous setting items where user awareness is needed, while continuous setting items operate without vibration feedback, thus maintaining operability while preserving necessary user awareness.
Solution Approach 2:
The patent introduces conditional feedback mechanisms where vibration is provided as feedback only when appropriate for the specific operation type. The system monitors the type of setting change and applies feedback selectively, ensuring users remain aware of important discrete changes without being disturbed by feedback during continuous adjustments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves operability by providing targeted vibration feedback only when setting values are changed discontinuously, avoiding unnecessary vibrations during continuous setting changes, thus enhancing user clarity and intuitive control.

AI summary
An information processing apparatus performs control such that an area having a predetermined shape is displayed on a touch-screen. The information processing apparatus detects a touch-slide operation, which is a sliding operation performed while the area having the predetermined shape is being touched. The information processing apparatus changes a setting value of a setting item assigned to the area having the predetermined shape in accordance with the touch-slide operation. The information processing apparatus 1) performs control such that a vibration in accordance with the touch-slide operation is generated in case where a first setting item is assigned to the area having the predetermined shape and 2) performs control such that the vibration in accordance with the touch-slide operation is not generated in case where a second setting item, which is different from the first setting item, is assigned to the area having the predetermined shape.
