Cylindrical Display for Multi-User Directional Information Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies, such as those described in Patent Literature 1, can disrupt discussions by requiring participants to shift their gaze towards a display when checking information related to the talk, thereby interrupting the conversation.
Innovation Solution
A display apparatus with a cylinder-like body that acquires direction information of multiple users and generates an output image displaying information corresponding to each user in their respective directions, allowing users to easily access and view information without disrupting the conversation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed on a conventional flat display, then information can be presented to users, but users must shift their gaze toward the display which interrupts the conversation
Solution Approach 1:
The patent transforms the conventional two-dimensional flat display into a three-dimensional cylindrical display. This dimensional change allows information to be distributed around the cylinder surface, enabling users to access information by rotating their heads or bodies while maintaining eye contact with conversation partners, thus eliminating the need to shift gaze toward a flat screen and preserving communication continuity.
Solution Approach 2:
The cylindrical display presents different information at different locations around the cylinder surface. Each user can access information relevant to their position or perspective without interfering with others. This localized information presentation allows multiple users to simultaneously access different information sets while maintaining natural conversation flow.
2Ease of operation
If a cylindrical display is used to present information in multiple directions, then communication continuity is maintained, but the device complexity increases
Solution Approach 1:
The patent employs a cylindrical (curved) display structure instead of a flat planar surface. This curvature allows the display to naturally present information in multiple directions around the cylinder, enabling users to access information by simply changing their viewing angle without requiring complex mechanical adjustment mechanisms or multiple separate displays.

AI summary
A display apparatus according to an embodiment of the present technology includes a display section, an acquisition section, and an image generator. The display section includes a display that has a cylinder-like body and on which an output image is displayed. The acquisition section acquires pieces of direction information that respectively indicate directions of respective users of a plurality of users as viewed from the display. The image generator generates the output image on the basis of the pieces of direction information such that pieces of information that respectively correspond to the users of the plurality of users are presented in the respective directions of the users of the plurality of users.
