Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia display systems fail to dynamically adjust their sensory inputs such as light, sound, scent, and airflow to effectively enhance user experience and cognitive performance in real-time based on user feedback, leading to suboptimal mood and productivity.
Innovation Solution
A system that integrates sensors to monitor user activities and physiology, using a control space with axes like focus and restoration to dynamically adjust multimedia displays, including visual, auditory, olfactory, thermal, and air current stimuli, to maintain or achieve a target physiological state through closed-loop feedback control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimedia display systems use fixed sensory inputs, then system complexity is reduced, but user experience and cognitive performance cannot be dynamically enhanced
Solution Approach 1:
The patent implements dynamic adjustment of multimedia display parameters (light intensity, sound volume, scent concentration, airflow rate, temperature) based on real-time user physiological feedback. The system transitions from static fixed inputs to dynamically adjustable sensory outputs that adapt to user state, resolving the contradiction between adaptability and complexity by making the system responsive rather than permanently complex
Solution Approach 2:
The system incorporates sensors that continuously monitor user physiological signals (heart rate, skin conductance, temperature) and feed this information back to the control algorithm. This closed-loop feedback mechanism enables the system to automatically adjust sensory inputs based on measured user response, achieving dynamic adaptability without requiring complex manual intervention
2Measurement precision
If sensors continuously monitor user physiology, then real-time feedback accuracy is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic sampling of physiological signals at optimized intervals rather than continuous monitoring. The control algorithm processes sensor data at discrete time steps, adjusting multimedia parameters only when significant changes in user state are detected. This periodic operation maintains measurement precision for controlling sensory outputs while reducing overall energy consumption compared to truly continuous monitoring
3Adaptability or versatility
If multiple sensory modalities are integrated, then user experience enhancement is improved, but control difficulty increases
Solution Approach 1:
The patent introduces a control space with multiple dimensions corresponding to different sensory modalities (visual, auditory, olfactory, thermal, airflow). Each dimension can be independently adjusted based on user physiological feedback. This dimensional approach to control allows systematic management of multiple sensory parameters, transforming the complexity challenge into a structured multi-dimensional control problem that can be solved algorithmically
Data Source
AI summary
A system may produce a multimedia presentation that includes visual stimuli, auditory stimuli, olfactory stimuli, thermal stimuli and air currents that are perceptible to a human user. All or part of the system may be housed in or affixed to a table or desk. Sensors may monitor physiology or activities of the user and provide feedback regarding the user's response to the presentation. A user may input instructions for the system. Based on these instructions, the system may present a multimedia presentation which tends to produce a target physiological state of the user that is specified in the instructions or which tends to maintain a current physiological state of the user. The system may employ a control space to control the presentation. This control space may have axes that correspond to how a user perceives multimedia presentations.
