Gesture-Based Presentation Control via Camera Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control methods for computing applications, such as computer games and presentations, are often difficult to learn, limited in navigation, and can be distracting, especially when multiple users need to share control, as they rely on controllers or direct input devices.
Innovation Solution
A gesture-based system that captures and recognizes user gestures in three-dimensional physical space, allowing users to control applications and presentations through body position and motion, enabling immersive interaction and shared control among multiple users without the need for traditional input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional controllers and input devices are used for presentation control, then control functionality is provided, but the controls are difficult to learn and create a barrier between user and application
Solution Approach 1:
The patent replaces traditional mechanical controllers with gesture-based control using cameras and computer vision technology. Users interact with presentations through natural hand gestures in the air, eliminating the need to learn complex button combinations or controller operations. The system captures gestures via cameras and translates them into presentation control commands automatically.
Solution Approach 2:
The gesture control system allows users to naturally control presentations using their own body movements without requiring external control devices. The system automatically interprets gestures and executes corresponding presentation actions, making the interface self-adapting to user intentions without requiring formal training.
2Adaptability or versatility
If controllers with limited buttons are used, then control is simplified, but navigation options are limited and commands vary extensively between different clickers
Solution Approach 1:
The gesture-based system provides universal control across different users and situations. A single hand gesture can trigger multiple different presentation actions depending on context, and the same gesture interpretation works consistently across all users. The system eliminates the need for different controllers for different users, providing a unified control language that adapts to various navigation needs.
3Ease of operation
If controllers are used during presentation, then control is available, but the controller use is distracting to viewers
Solution Approach 1:
The patent extracts the controller from the physical interaction space and replaces it with gesture-based control. Users no longer need to physically hold and manipulate controllers while presenting, eliminating the visual distraction of holding devices. The control function is extracted from the hands and translated into invisible gesture commands that don't interfere with the presentation visual field.
4Adaptability or versatility
If multiple users share control using controllers, then collaborative control is enabled, but users must each have access to the controller and hand it around
Solution Approach 1:
The system merges multiple users' control capabilities into a single shared control space. Instead of distributing physical controllers to each user, the gesture recognition system captures inputs from multiple users simultaneously in the same physical environment. The system identifies which user performed which gesture and attributes the control command to the appropriate user, enabling seamless collaborative control without physical device sharing.

AI summary
Techniques for managing a presentation of information in a gesture-based system, where gestures are derived from a user's body position or motion in the physical space, may enable a user to use gestures to control the manner in which the information is presented or to otherwise interact with the gesture-based system. A user may present information to an audience to an audience using gestures that control aspects of the system, or multiple users may work together using gestures to control aspects of the system. Thus, in an example embodiment, a single user can control the presentation of information to the audience via gestures. In another example embodiment, multiple participants can share control of the presentation via gestures captured by a capture device or otherwise interact with the system to control aspects of the presentation.
