Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic presentations lack flexibility in adjusting slide content and order during a speech, failing to respond to audience emotions or time constraints, limiting dynamic interaction.
Innovation Solution
A method and apparatus for dynamically processing and playing multimedia content by generating a topic map, determining play order using reinforcement learning and Bayesian optimization, and adjusting content based on real-time constraints and emotional features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electronic presentation follows preset order, then presentation structure is stable and easy to control, but flexibility to adjust content and order during speech is lost
Solution Approach 1:
The patent implements dynamic adjustment of presentation content and order during speech by generating topic maps from knowledge bases and using reinforcement learning to select optimal content sequences. The system can add, delete, or rearrange slides based on real-time constraints such as time limits or audience feedback, transforming the static presentation into a dynamic adaptive system.
Solution Approach 2:
The system performs self-organization by automatically generating topic maps from knowledge bases, selecting relevant content through reinforcement learning, and arranging slides without requiring manual intervention. The reinforcement learning agent autonomously makes decisions about content selection and ordering based on predefined constraints and reward functions.
2Adaptability or versatility
If traditional presentation uses fixed slides, then preparation is simple and reliable, but ability to respond to audience emotions and time constraints is lost
Solution Approach 1:
The system incorporates feedback mechanisms where reinforcement learning agents observe the outcomes of content selection and adjust future decisions accordingly. The topic map generation process continuously refines content selection based on constraints such as time limits or audience engagement levels, creating a closed-loop system that learns from previous performance.
Solution Approach 2:
The patent changes key parameters of the presentation system including content selection criteria, slide ordering, and timing adjustments based on real-time constraints. The reinforcement learning framework modifies these parameters dynamically to optimize presentation effectiveness under varying conditions such as audience response or time remaining.
3Productivity
If presentation content is pre-arranged, then playback is straightforward and reliable, but dynamic rearrangement based on situation is impossible
Solution Approach 1:
The system performs preliminary actions by pre-generating topic maps from knowledge bases and pre-calculating potential content sequences using reinforcement learning. This preparation allows the system to quickly select and execute optimal content arrangements during actual presentation without requiring complex real-time computation, maintaining playback efficiency while enabling dynamic rearrangement.
Data Source
AI summary
A method for dynamically processing and playing multimedia contents and a multimedia play apparatus are provided. A topic map is generated based on a title. The topic map has a plurality of nodes, and each node corresponds to one of the multimedia contents. Multiple node groups are obtained through permutation and combination of these nodes. A target group that matches a constraint is found among these node groups. A play order of each node in the target group is determined according to at least one reward table. One or more multimedia contents included in the target group are processed and played according to the play order.
