Interactions with Sponsors
- First Sponsor Interview
- Interviewers: Jeff Rebmann, Rochelle Perry, Yi Xie
- Sponsor: Dr. Brown
- Date 3 April 2009
- Jeff: How much were you involved in the motion tracking?
Brown: I was the guide and the customer
- Jeff: What was the history?
Brown: My research is in human robot interaction for rehabilitation. Wanted to come up with a device for extracting upper extremity motion behavior via physiological and biomechanical information. Interested in the electromyographic signal from the persons skin from muscle contraction. Also wanted biomech info from the elbow joint and the shoulder rotation. 3 degrees of freedom for the system. This is project P09027 this past quarter. Just got finished. Wanted to extract info and also have a nice gui. You would need at least 2 me, 2 ce, and 2 ee. Everybody should learn each others skill sets.
- How was it captured?
Brown: Using potentiometers to map voltage from the system. Bought an emg device to shorten development time. The device also comes with a software kit. Building a amplifier system is a project in itself, would have been way too long. Went with off shelf system (bio-radio $6k from Cleveland medical) made the rest. Primary application was for a robot, where arm movement will be translated to robot motion. System has many different functions, in the gui and actual device, allowing it to be used in various applications. Hence more diverse team. IE would be good for the ergo part.
- Where does this project stand.?
Brown: It is pretty much completed but the software still needs tweaking. Tends to crash.
- Are you interested in furthering this project?
Brown: For now its good, but there is a lot of ways to integrate it to the next level. There wasn't anything like this on the market and it integrated many skill sets so the project was a success.
- How can we integrate this to the upper extremity exerciser?
Brown: You would need sensors. Maybe not an emg but potentiometers are quite cheap. You will also need software support. You want to evaluate other motion tracking systems out there. Software platform called QT was used in our motion tracker.
- What other types of applications do you see this motion tracker in?
Brown: Whatever types of ailments, a motion tracker can give you some insight to further assess things happening in their body such as muscle activity. Some people have movement in their arms but no control, the GUI can give them feedback for what's going on
- instead of just looking at existing projects, design for peoples needs. Start with needs, build from there, and design around them. Once those needs are established, you can come back and look at the diff systems available and see how they can be incorporated.
