Project Summary

Virtual reality allows a user to experience events in a 3D environment. It can be used for entertainment as a tool that allows researchers to create correlations between eye movements and responding body movements. Current systems use tracking sensors and cameras to monitor movement of the body, but these system prove to have difficulty when focusing on the hands. The cameras have difficulty following and seeing the sensors located on the hand which produced inaccurate data. The interest of this project is to create a glove that produced data that can be used to relate eye movement and hand movement without the use of optical sensors. There are currently commercial gloves that allow tracking of hand positions without cameras, but are too expensive. Constraints of this project include developing a lightweight, durable, and cost effective, virtual reality glove that will not interfere with the natural movements of the user. The functioning prototype glove will provide data of the hand's position that can then be compared to the movements of the the user's eyes for study.

Preliminary Interview Questions and Answers

Number Questions Answer
1 How can we get a hold of you? Send email to set up appointment/meeting a couple days in advance or go to office or lab in CAR(76)-2100 and 2101. Can also contact Susan Farnand. May be put into contact with a grad student later in the semester for more information
2 If there is a current idea, under what circumstances does the current idea fail? Currently using active markers to track movement using cameras. Other working models include the Cyber Glove and similar products.
  • Pros:
    • light weight
    • robust (does not break down over time)
    • tracks grip rate and movement
    • does not restrict movement
  • Cons
    • gets blocked at certain angles and information is lost
    • does not provide feedback to simulate coming into contact with ball
    • does not track onset of closure or rate of closure
    • does not track rate of change of movement
    • does not track the spread of fingers or movement of wrist
    • should be available in right and left handed
3 What is our deliverable?
  • Prototype
  • Fully functional
  • Ready for sale
Fully Functional Prototype
4 What types of data do they want outputted?
  • pre-filtered or pre-processed
Pre-filtered
5 What actions are going to be simulated? Catching and hitting a ball
6 What software are we interfacing with?
  • will the software be able to filter the data to show how it is a finger
Python
7 Who approves the device? The device is approved at several stages throughout the course by both students and the customer
8 Who is in control of the funds?
  • What is our expected budget?
The budget will be determined at a later date. Probably between $500 and $1000
9 Who is the user? Volunteers working in the lab. Mostly college age students
10 What are the hand sizes range? Must fit men and women in college and most adults
11 What is the range of communication? Lab is not currently wireless, so wired connection is acceptable.
12 Is a battery absolutely necessary? Yes.
  • Must be able to buy replacements to have on hand in case of a power outage
  • Must have a battery life of at least 4 hours
13 How accurate does it have to be? +/- 2 degrees? Within a few degrees. Will be determined after some testing has been done.
14 Is it 120 Hz because we are trying to match the data rate with the cameras? Can be lowered to be at least 60 Hz. Anything slower than that may cause problems with providing feedback to the user
15 Why is it 2 lbs for the peripheral components? can it heavier? This is a flexible number. The user will be wearing a fanny pack which can hold the battery and possible other small controls
16 Where do you want the location of peripheral components? (arms,back,chest) Undecided
17 How long do you want for calibration time? Undecided
18 What are the operating conditions? In a lab in CAR building. Can be viewed at a later time to get a better understanding
19 What is the operating life? Undecided
20 Any other faculty or people we can ask for advice? Susan Farnard and a grad student we may be put into contact with will be able to help if needed.
21 Does it have to be a glove? No. The design is flexible. Simply needs to be able to track hand movement according to customer needs and engineering requirements

Project Goals and Key Deliverables

For our customer we aim to have a fully functioning prototype glove that can be used for testing and data collection. With this glove it is our goal to create a manual for reference, including a instructional document for repairs and where to get parts.
