Speaker Position Control via Visual Cursor Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face difficulties in acquiring position information for multiple speakers, especially when the viewing position changes, as it requires complex measurements and calculations to determine the azimuth and elevation angles of physical or virtual speakers.
Innovation Solution
A control device that includes a generation unit for converting image data using shape information, a display controller for displaying images and superimposing a cursor, and an identification unit that calculates the cursor's position in space based on user input, allowing for intuitive designation of speaker positions without direct numerical input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional measurement and calculation methods are used to determine speaker positions, then position information can be obtained, but the process becomes complex and difficult when viewing position changes
Solution Approach 1:
The patent creates a visual copy of the three-dimensional speaker positions on a two-dimensional display screen. The display image reproduces the spatial arrangement of speakers, allowing users to designate positions visually rather than through complex measurements. This copying approach simplifies the interaction while maintaining position accuracy.
Solution Approach 2:
The patent replaces physical measurement tools and complex calculation systems with a visual display and cursor-based selection interface. Instead of using measuring instruments or performing mathematical calculations to determine speaker positions, users simply move a cursor on the displayed image to select positions, substituting mechanical and computational complexity with intuitive visual interaction.
2Measurement precision
If direct numerical input is required for speaker positions, then precise position data can be obtained, but ease of operation decreases
Solution Approach 1:
The patent displays a visual representation (copy) of the speaker positions and spatial relationships on a screen. Users interact with this visual copy by moving a cursor to desired positions, eliminating the need for direct numerical input while maintaining precision through the visual feedback provided by the display image.
Solution Approach 2:
The patent introduces a cursor as an intermediary between the user and the position designation system. Instead of directly inputting numerical coordinates, users control the cursor to visually select positions on the display image, and the system automatically converts these visual selections into precise position data, serving as a mediator that simplifies operation while maintaining accuracy.

AI summary
A control device controls sound of a plurality of speakers. The control device includes: a generation unit acquiring image data and generates display image data from the image data by using conversion processing using shape information indicating a shape of a display surface; a display controller displaying a display image on the display surface by using the display image data; a receiver causing a cursor to be superimposed and displayed on the display image and receives position designation related to the plurality of speakers on the display image from a user who has visually recognized the cursor; and an identification unit calculating a position of the cursor from the position designation by referring to a correspondence relationship between the image data before the conversion processing and the display image data after the conversion processing, and identifying the position of the cursor as a position related to the plurality of speakers.
