Interactive Presentation Modules with Event-Driven Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide show applications are limited in interactivity, constraining users with structured templates and unsuitable for two-way communication, lacking the ability to provide individual interaction for audience members beyond one-way information dissemination.
Innovation Solution
An authoring and playback mechanism for multimedia presentations that allows interactive collections of activities, where each activity consists of frames with presentation modules that can include media content and organized tasks, enabling user input to navigate or perform actions, and system events to trigger module actions, facilitating non-linear branching and adaptive experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If structured slideshow templates are used to generate presentations, then the ease of manufacture is improved, but the adaptability or versatility deteriorates
Solution Approach 1:
The presentation is divided into discrete modules including activities, frames, and presentation modules. Each module can be independently created, configured, and assembled. Activities contain frames, and frames contain presentation modules, creating a hierarchical segmented structure that enables both ease of creation through templates and versatility through flexible recombination of segments.
Solution Approach 2:
The system employs universal container structures (activities and frames) that can hold various types of content including media content, organized tasks, quizzes, and interactive elements. These universal containers can be reused across different presentation contexts, providing ease of manufacture while maintaining adaptability through their multi-functional nature.
2Device complexity
If conventional slide show applications are used, then the device complexity is reduced, but the adaptability or versatility deteriorates
Solution Approach 1:
The presentation structure transitions from static slides to dynamic activities and frames. Activities can branch based on user interactions, frames can be invoked conditionally, and presentation modules can respond to events. This dynamic structure enables rich interactivity while maintaining manageable complexity through the organized hierarchical framework.
Solution Approach 2:
The system introduces an intermediary layer of activities and frames between the basic presentation modules and the final presentation output. This intermediary structure mediates between simple media content and complex interactive behaviors, allowing versatile interactivity while keeping the underlying application structure relatively simple through abstraction.
3Ease of operation
If one-way communication format is used, then the ease of operation is improved, but the adaptability or versatility deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms through user events and system events that trigger actions. User input during playback can navigate between frames, invoke presentation modules, or change presentation flow. This feedback loop enables individual interactivity for audience members while maintaining ease of operation through intuitive event-driven interactions.
Solution Approach 2:
The presentation transitions from a static one-way communication format to a dynamic interactive experience. Activities can branch based on user responses, frames can be conditionally invoked, and presentation modules can adapt their behavior based on events. This dynamic adaptation provides individual interactivity while preserving ease of operation through the structured event-action framework.

AI summary
A presentation application provides for authoring and playback of a presentation. A presentation is an interactive collection of activities. An activity may include one or more frames, wherein each frame includes one or more modules. A module may consist of media content such as video, text, images or other content. A user may provide input during playback of the presentation. In response to the input, the module or frame receiving the input may call an action on a presentation activity, frame or module, thereby allowing the user to navigate through the presentation and accomplish objectives. When authoring a presentation, a user may associate a user initiated event or internally generated event with a module action. Authoring may be performed through an authoring interface provided by an authoring tool. The authoring tool may save a presentation as a package which can be distributed.
