Smart Glasses Tracking via Laser Impact Point for Visual Impaired Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart glasses for visually impaired users have low informing efficiency and poor user experience due to the inability to actively select the interactive center, resulting in the device providing all image information at once and difficulty in accurately focusing on specific objects or characters without external assistance.
Innovation Solution
A smart glasses tracking method that adjusts operating modes based on movement speed, captures images, identifies objects, and informs users of specific objects at predefined positions or regions, using a laser impact point to focus on central or predefined areas, thereby improving informing efficiency and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If smart glasses inform the user of all information in the image at the same time, then the user receives complete information, but the informing efficiency is low and the user experience is poor
Solution Approach 1:
The patent extracts only the necessary information from the complete image data by identifying objects at the impact point of laser light. Instead of presenting all detected objects, the system selectively outputs information only for objects located at the predefined focus position, thereby improving informing efficiency while maintaining information quality for the user's current focus.
Solution Approach 2:
The patent applies local quality by differentiating information presentation based on spatial location. Objects at the impact point of laser light (predefined position) receive priority information presentation, while other objects are either not presented or presented with lower priority. This localized information delivery optimizes the user experience by focusing on the most relevant information.
2Device complexity
If smart glasses cannot actively select the interactive center, then the device structure remains simple, but the device cannot accurately focus on specific objects or characters
Solution Approach 1:
The patent introduces an intermediary mechanism (laser light with a visible impact point) to indicate the focus position. This intermediary allows the system to actively select and highlight the interactive center without requiring complex additional hardware for direct manipulation, thereby improving focus accuracy while maintaining relatively simple device structure.
3Loss of information
If smart glasses provide all image information at once, then the user has access to complete data, but the user cannot perceive the location of objects in the field of view
Solution Approach 1:
The patent uses visual differentiation (analogous to color changes) by highlighting objects at the impact point of laser light. This visual marker enables users to easily distinguish the focused object from other objects in the field of view, improving object location perception while maintaining information availability for all detected objects.

AI summary
The present disclosure provides a tracking method and apparatus for smart glasses, smart glasses and a storage medium, and is directed to smart devices. The smart glasses may capture an image and then identify one or more objects in the image. The object located at a predefined position or region in the image is informed to a user. With the method, rather than all of the objects in the image, the object at the predefined position or region is informed to a user, such that the informing efficiency of the smart glasses and user experience are improved.
