Possible Data Capture Scenario

Penny has provided som initial thoughts and exaple scenarios on the requirements for data capture:

Variables we need for analysis

  1. Total time playing games = sum of all sessions
  2. Distribution of sessions ie how closely they followed recommendation = plot of session frequency and length
  3. We can also look into whether they were improving in their scores, using all games and progressing through levels but this may be descriptive rather than quantitative.

File shows the record for participant number 1 who was allocated to falcon (device 1) group. They logged on first when the therapist was there on 16 March 2010 and started playing first game at level 1. Read more

Ship Game Concept

Description of User Movement

In this concept the Users hand represents a ship moving in 3D space. As the user moves their hand in the XY planes the ship responds accordingly. Rotation of the hand is also used to bank the ship. 

Movement in the Z plane or extension/contraction of the finger span can be used to control ship speed depending upon user ability. Read more

Balloon Grap Concept

Description of User Movement

The user has to move the hand in the X and Y plane to line up with a moving object. The user then has to grab the object via movement in the Z plane and a corresponding pinch action of the correct span to encase the object. Read more

Peg Test Concept

Description of User Movement

The user has to move the hand in the X and Y plane to line up with a peg. The user then has to move in the Z plane and use a pinching action to grab the peg. The user then has to move in the XY planes in order to reposition the peg in a desired location.

Placement is derived via the release of the pinch action. Read more

Archery Game Concept

I thought it would be a good idea to get a version of the Games Concepts up on line, so here is the first one:

Description of User Movement

User moves hand forward and then uses a pinching action to load an arrow. Force is applied to the arrow either by moving the hand backwards or via the period the pinch is held depending upon the user’s ability.

Once primed, the arrow can be aimed at the target via movement in the X and Y planes. The arrow is fired via the releasing of the pinch. Read more

WiiGlove Prototype One

A quick demo of the new Wii Glove being developed. Unlike most Wii Glove developments this glove also has facility for Accelerometer data:

A low cost rehabilitation glove using the capacity of the Infrared Receiver on Nintendo’s Wiimote to pick up the signal from four diodes placed at the patient’s fingertips. This compensates for the inability of previous low cost solutions to track fine motor skills. Four diodes per glove are used as it is only possible to track that number of separate Infrared Signals per Wiimote

Hello world!

As the project is really starting to move now I thought it would be a good idea to create a project website where we can archive our developments and communicate our thoughts.

If you all have any comments/ requirements please just send me a mail at my NTU address and ill look into them etc.
