AR Glasses Calorie Intake Management via Video Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meal management technologies cannot effectively manage the speed of meal consumption or the order of eating, only providing calorie and nutritional balance information without addressing the timing and speed of ingestion.
Innovation Solution
A wearable device, such as augmented reality glasses, captures video of a user eating and calculates nutrient intake, determining an appropriate order of ingestion and alerting the user to adjust their eating speed based on real-time nutritional data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video data of user eating is captured and analyzed in real-time, then meal speed and order of ingestion can be managed, but device complexity and processing requirements increase
Solution Approach 1:
The patent uses an imaging unit (camera) as an intermediary to capture video data of the user's eating process. This visual intermediary allows the system to indirectly measure meal speed by analyzing the sequence and duration of eating actions in video frames, rather than requiring direct physiological sensors. The video data serves as a mediator between the user's natural eating behavior and the management device's analysis capabilities.
Solution Approach 2:
The patent replaces complex mechanical or physiological measurement systems with optical-based video analysis. Instead of using sensors to directly measure ingestion speed or biochemical markers to assess meal composition, the system substitutes these with computer vision technology that processes video data to infer eating behavior patterns, meal speed, and food item identification.
2Measurement precision
If real-time video analysis is performed to determine ingestion state, then meal management accuracy improves, but processing time and energy consumption increase
Solution Approach 1:
The patent applies partial action by selectively analyzing only the necessary portions of video data for determining ingestion state. Rather than processing every frame in full detail, the system identifies key moments when food items are brought to the mouth or consumed, and focuses analysis on these critical events. This selective processing reduces overall computational energy requirements while maintaining accurate detection of meal speed and composition.
3Loss of information
If notification is provided to user during meal, then user awareness of eating speed improves, but user convenience may be reduced
Solution Approach 1:
The patent implements feedback by providing notifications to the user during the meal process when the detected eating speed exceeds a predetermined threshold. The notification unit delivers timely information about excessive meal speed, allowing users to adjust their eating pace in real-time. This feedback loop maintains user awareness of their consumption patterns while enabling them to make voluntary adjustments to improve their eating habits.

AI summary
To manage calorie intake per unit time. An AR glasses include: a calorie calculation unit that calculates calories of food or drink ingested by a user per predetermined unit time (for example, 1 minute) based on a video obtained by imaging food or drink consumption by the user; and a management unit that outputs a warning to the user in a case where the calories of the food or drink ingested by the user per unit time calculated by the calorie calculation unit exceed a threshold and determines whether or not the food or drink consumption by the user has been finished, in which the calorie calculation unit and the management unit repeat processes thereof until it is determined that the food or drink consumption has been finished.
