Tilt-Activated Page Navigation With Touch Stop Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with page-turning functions, such as e-book readers and tablets, face difficulties in efficiently navigating through pages, as they require button operations, making it hard to find desired pages like in printed books.
Innovation Solution
Incorporating a touch panel and circuitry that detects the tilt of the device, allowing page switching by tilting the device and stopping page turning when a specific area of the touch panel is touched, mimicking the page-turning experience of printed books.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If page turning is performed by button operation, then page switching is achieved, but efficient page navigation like in printed books becomes difficult
Solution Approach 1:
The patent replaces the mechanical button operation system with a tilt detection system using accelerometers and a touch panel. The device detects tilt direction and touch position to determine page turning direction and stopping position, enabling more efficient page navigation that mimics printed book interaction.
Solution Approach 2:
The patent introduces tilt detection and touch panel input as intermediary mechanisms between the user and page navigation. The accelerometer detects device orientation, and the touch panel captures user intent, together serving as mediators that translate physical gestures into page turning actions without requiring direct button presses.
2Ease of operation
If tilt detection is used for page turning, then intuitive page navigation is enabled, but device complexity increases
Solution Approach 1:
The patent makes the accelerometer serve multiple functions: it detects both the tilt direction for determining page turning direction and the touch position for determining where to stop page turning. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while maintaining intuitive operation.
3Productivity
If continuous page turning is enabled by tilt, then efficient page browsing is achieved, but control over stopping position becomes difficult
Solution Approach 1:
The patent implements feedback by continuously monitoring touch panel input during page turning. When the user touches the screen at a specific position, the system receives this feedback and stops page turning at the corresponding position, giving the user precise control over where to stop while maintaining fast browsing through continuous tilt-based page turning.

AI summary
According to one embodiment, an electronic device includes a display configured to display a content including pages, a touch panel on the display, and circuitry. The circuitry is configured to detect a tilt of the device, switch a displayed page from a first page to a second page when the device is tilted in a first direction, and when a contact on a partial area of the touch panel corresponding to the first direction is detected, stop switching of a displayed page based on a tilt of the device in the first direction.
