Project Overview

Current Concept Virtual Reality is used to simulate 3D environments using  multiple cameras, sensors, and immersive displays Most people know it from video games but it can be used for  research applications  Relate eye movements to their corresponding body movements (our project) Training in specialized tasks  Healthcare  Current techniques use markers in combination with  cameras to track hand motion In some positions, markers are occluded from optical view,  resulting in missing data points

Current Concept

Problem Statement Current State   Current techniques use active markers with cameras to track hand motion Desired State   The project will focus on providing a functional prototype to track hand movement that is lightweight, durable, and relatively inexpensive The glove will not interfere with user’s natural hand movements   Sensors transmit useable motion data to the computer for analysis Project Goals   Analyze current designs Identify opportunities for improvement of benchmarked designs  ○ Lighter ○ Better data rate ○ More accurate ○ Cheaper Constraints   Must be able to stay within budget means ($1000)

Project Status  Major Components of the overall system are functional Most Engineering Requirements were met in full   Flex Sensors and lightweight glove assembly provides a cost efficient Data Glove  The glove allows more information for hand movements with correlating eye movements in addition to camera markers in the Virtual Reality Environment providing more accurate research  All sensors are functional provide signal in real-time to be processed in python Awaiting orders for PCB board to make final creation of the  glove ○ Due by Tuesday 12/9

Repeatability Test Result Sample Middle Finger, Main Knuckle Pre-Calibration Calibration Equation y = -0.0558x 2 + 9.6141x + 3288.9 Middle Finger, Main Knuckle Post-Calibration

Remaining Opportunities  Create veins on glove to house wires  Gather additional characterization data now that filtering is functional  Revise signal conditioning circuit board to use full signal scale  Develop Python-based calibration calculations  Evaluate other knuckle assembly mounting solutions

MSD I Budget  The Budget for this project was $1000  Our team spent around $860 of that budget. Majority of the purchasing money was used for buying  Microcontroller parts, PCBs in a timely fashion, and flex sensors.
