This is the printable sheet for ScanBand v0.4.

This is a 11x17 inch sheet of paper that holds two copies of the ScanBand. They also will fit on an 8.5x14 legal sheet. The two strips you see cut out are cut further, folded, and glued together to make a completed ScanBand.

This is the top-most portion of the ScanBand. It is built with the small windowed piece, which is flipped over and turned 90 degrees over the band. Its flaps are then glued or taped around the back.

With all the pieces glued together, the ScanBand should look like this.

Once assembled, the ScanBand should look like this.

This is the area of the ScanBand that the bar-code scanner is designed to hit. The numbers also give human-readable output for the measured circumference.

Becky Heritage models the ScanBand, which is fitted to her arm circumference.

The bar-code scanner is fired at the ScanBand on Becky's arm and a measurement is sent to the computer.

Version 0.2 of scanband increases the size of the measuring window to 5 mm and adds a colored warning strip to allow for quick diagnosis of dangerously diminished mid-upper arm circumference. The barcode gradient in this might be inverted (snafu) and the strip still needs a numerical readout. Also, a window system that folds over the strip, rather than relying on cut slits, would be easier to fit on patients.

ScanBand v0.2Thursday night marked the first presentation of my thesis work to outside critics. It went well, despite a snafu with the barcode scanner that prevented the ScanBand from displaying its results on screen. As a non-digital user scenario, though, it was fine.

Here's the breakdown of my presentation. I've also attached the PDF of the show and a PDF of the version 0.2 ScanBand prototype, which is made available under the Creative Commons Attribution-ShareAlike License 3.0
