1 minute read

Published:

This post outlines a conceptual design for a smart glove system that combines tactile sensing, AI analysis, and 3D visualization to assist in detecting subcutaneous abnormalities such as tumors.

1. System Architecture

Smart Glove Hardware

  • Tactile Sensors: Embedded in the glove to detect pressure, hardness, and tissue morphology
  • Position Tracking System: Micro IMU (Inertial Measurement Unit) or optical sensors on the glove to record movement trajectories on the body
  • Data Transmission Module: Real-time data transfer via Bluetooth/Wi-Fi to a computer or mobile device

AI Analysis and Modeling Software

  • Tactile Data Analysis: AI model converts sensor data into hardness maps indicating potential tumor locations
  • 3D Model Generation: Real-time trajectory recording combined with 3D modeling algorithms to construct tissue models of the examined area
  • Tumor Annotation: Highlights high-hardness regions in the 3D model with size, location, and depth information

Display Device

  • Real-time visualization on AR glasses, tablets, or screens showing the 3D model and annotated tumor locations

2. Technical Core

Tactile Sensors and Data Acquisition

  • Pressure Sensors: Detect pressure distribution and generate hardness data
  • Flexible Sensors: Conform to body contours and capture subtle tactile variations

3D Modeling and Reconstruction

  • SLAM (Simultaneous Localization and Mapping): Generates real-time 3D models using glove position data
  • Point Cloud Generation: Accumulates touch points into point clouds, then applies surface fitting techniques to create smooth 3D models

AI Model Analysis

  • Hardness Classification Model: Machine learning (e.g., CNN) analyzes tactile data to detect hardness anomalies
  • Segmentation and Annotation: Marks abnormal regions in the 3D model and calculates specific tumor parameters (diameter, depth)

3D Visualization

  • Tools like Unity or Blender generate 3D tissue models
  • Real-time rendering of examined areas with highlighted tumor regions

Future Work

This design concept could be extended to include:

  • Integration with medical imaging data (ultrasound, MRI) for validation
  • Haptic feedback for the examiner
  • Clinical trials for accuracy assessment
