Aerial Imaging Element Teleprompter for Compact Camera-Friendly Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional teleprompters are not convenient for motion shooting due to the large and fragile beam splitter, which requires frequent adjustments of the tripod head and limits their usability in scenarios like news broadcasting and lecture giving.
Innovation Solution
Incorporating an aerial imaging element with optical elements such as transparent or translucent spheres or right angle mirrors, arranged on a horizontal plane and fixed to a substrate, which form a real image in the air above the display screen, allowing for a more compact and user-friendly teleprompter system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a beam splitter is used in the teleprompter, then the text can be reflected to the user, but the beam splitter becomes large and fragile, requiring frequent adjustments of the tripod head
Solution Approach 1:
The patent extracts the beam splitter from the teleprompter system and replaces it with an aerial imaging element that projects the image directly into the air. This eliminates the need for the beam splitter and tripod head adjustments, directly resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The aerial imaging element creates a virtual copy of the displayed text in the air, allowing users to view the prompt without physical contact with any reflective surfaces. This copying approach eliminates the fragility and adjustment issues of the beam splitter while maintaining the text reflection function.
2Ease of operation
If a large beam splitter is used, then the text reflection function is achieved, but it interferes with the camera's view and video recording
Solution Approach 1:
The patent removes the beam splitter from the optical path between the display and the user's eye, replacing it with an aerial imaging element that forms the image in mid-air. This extraction eliminates the physical obstruction that interferes with camera shooting while preserving the text reflection capability.
Solution Approach 2:
The aerial imaging element acts as an intermediary between the display screen and the user's eye, creating a virtual image in the air that can be viewed without blocking the camera's line of sight. This mediator approach resolves the conflict between text reflection and camera accessibility.
3Ease of operation
If a traditional teleprompter structure is used, then the text can be displayed, but the structure is complex and requires multiple components including monitor, beam splitter, and tripod head
Solution Approach 1:
The patent merges the display screen and aerial imaging element into an integrated teleprompter system. The imaging element is disposed directly above the display screen, combining multiple functions into a single compact device and eliminating the need for separate tripod head and beam splitter components.
Solution Approach 2:
The aerial imaging element serves multiple functions: it reflects text for user viewing, eliminates the need for beam splitter adjustments, and does not interfere with camera shooting. This multi-functional component reduces overall device complexity while maintaining all necessary operations.

AI summary
An aerial imaging element in a teleprompter system, a teleprompter and a teleprompter device includes one or more optical elements that bend incident light of an image and form a real image in the air, and further includes one or more translucent reflectors. The aerial imaging element is convenient to manufacture and is low in cost; the aerial imaging element enables an image displayed therein to form a real image in the air, which can be seen only at a certain angle. The aerial imaging element is applied to the prompt of aspects, such as news broadcasting and lecture giving, which is convenient and does not influence viewing or video recording at the scene.
