The following links are to the latest videos of the games in action. (All captured at NTU by Andy Burton)

Here we have another quick video, this time demonstrating Marker-less Motion Capture implemented with the current games as a glove alternative.
The system utilizes tracking via the Open CV library.
Further to Steven’s images I thought I should add some at home in a less ‘officey’ room. The monitor in this case is 19″.
Andy has informed me that at the meeting last week the project team requested a couple of shots of the Glove and software in situ.
I hope these do the job. If anymore are needed or these are not suitable send me a mail with an outline of requirements and ill take some more etc.
A quick video to demonstrate the CLAHRC Games Installer and a request for required license content logos etc from the team.
As you can see the installer is of the standard windows type and handles all the prerequisites needed in order to run the game.
Andy has provided me with the following outcomes from yesterdays meeting. Please take a look and provide any additional comment if necessary:
Calibration Data Capture: Can the data from the calibration game be stored like the game results – to allow the user to assess improvement in their mobility stats over time. This is analogous to a ‘body test’ on Wii Fit. Data required for this is (as we have I believe) rotation min, rotation max, pinch min, pinch max, reach (z position) min and max, along with position x and y min and max.
As an idea maybe this could display original (first calibration results), previous (last calibration results) and current data (this set of calibration results) for comparison after the user finishes the calibration ‘game’?
Workshops: It was agreed that we would do some workshops at both Mansfield and City Hospital – to get feedback on system iterations from patients/physios whilst in development. This will be starting with one in Mansfield in mid-late July.
Glove: All agreed that a rechargeable glove would be useful but were otherwise happy with the current design.
Games: It was confirmed that the requirement for final delivery is 3 games and a calibration game.
BallGrab Game: Now ‘Bubble Popper’ –which emerged from a brief brainstorming exercise at the meeting. Concept: Bubbles (of the same size – to aid in depth judgment) appear in the 3D game environment (one at a time). The user has to reach out and grab them gently. (this means pinch to the correct amount – not too much or bubble will pop) they then drag the bubble to a ‘pin’ object at the front of the play volume and ‘pop’ the bubble on it. Aim of this game is to exercise the arm in reach and grab scenarios.
This is the vague concept, which seems to work ok. Harder levels could involve the bubbles getting smaller, or further away increasing pinch and reach exercises respectively. I’m sure we can nail this concept down with a brief chat.
Deadline: Final version after workshop iterations to be delivered for 1st September.
Whilst I have been away the team have decided to rationalize the design of the glove via the removal of the accelerometer and buttons.
This has greatly reduced the both complexity of the glove and its weight etc, however the knock on effect from this is that I will have to re address the current implementation of the tracking lib as it relied heavily on the use of accelerometer data for point filtering etc.
Above are a few images of the new TP1 (Team Prototype One) glove setup.
For those who have seen the glove before, I have rationalized the Velcro loops to reflect the previous iterations of the glove. This acts further enhances the pinching capability.
Primary concerns at this point are the performance of the new systems power source and its overall efficiency.
I have addressed all the sites SPAM and have taken precautions to prevent future attacks via the installation of a new and improved CAPTCHA system for both commenting and mail posting.
The above images shows the new system in action. To check it out in real time please try making a comment. Also, please note the audio equivalent for accessibility etc So from now on things should get back to normal
Hi folks, just a quick note to say that I am now back from long term sick leave and am once again healthy and raring to go. Whilst I have been away the site has been the victim of spammers. As soon as I have cleaned up the spam mess I will get back to posting progress and project information as normal.
At Penny’s request I have begun to set up a page ready to include some FAQs and troubleshooting tips for the kit usage etc. In addition I am also creating a Forum via http://community.isrg.org.uk that we can use for obtaining feedback and log issues etc.
If there are any suggestions for content and/or additional requirements, please don’t hesitate to contact me.
