Display Control Unit for Voice-Output Document Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for outputting electronic text as voice do not adjust the display layout accordingly when the voice output position changes, leading to misalignment between the voice output and the display layout.
Innovation Solution
An information processing apparatus and method that dynamically adjusts the display layout on a screen to ensure the voice output position remains visible, using a display control unit to reposition the document on the screen based on the voice output unit's position during changes in display layout, such as orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display layout is changed during voice output, then the display layout can be optimized for different viewing conditions, but the voice output position may no longer be arranged within the changed display layout
Solution Approach 1:
The system performs preliminary action by detecting the voice output position before changing the display layout, and uses this information to determine the new display layout parameters. This ensures that the character being output as voice will be positioned appropriately in the new layout, preventing misalignment between voice output and display position.
Solution Approach 2:
The system implements feedback by using the detected voice output position as input for determining the new display layout. The voice output position information feeds back into the display control process, allowing the system to adjust the display layout parameters based on the current voice output state, thereby maintaining alignment reliability.
2Ease of operation
If the display layout is changed to optimize for different viewing conditions, then user comfort is improved, but the character being output as voice may become hidden or misplaced
Solution Approach 1:
The system detects the voice output position before executing the display layout change, using this preliminary information to calculate appropriate display parameters for the new layout. This ensures that the character being output as voice remains visible and properly positioned after the layout transition, preventing information loss.
Solution Approach 2:
The voice output position detection results feed back into the display control logic, allowing the system to adjust the new display layout parameters based on the current voice output state. This feedback mechanism ensures that layout optimizations do not cause the voice output character to become hidden or misplaced.

AI summary
Upon detecting input of an instruction to change a display layout of a document on a display screen, display control of the document on the display screen is performed so that a character output as a voice by a voice output unit at the time of detection is displayed on the display screen.
