The Baobab Bar-Code Band

ScanBand v0.4 Completed

ScanBand v0.4 Completed

Once assembled, the ScanBand should look like this.

ScanBand v0.4 Scan Window Area

ScanBand v0.4 Scan Window Area

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.

ScanBand v0.4 Scanned on the Arm

ScanBand v0.4 Scanned on the Arm

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

ScanBand v0.2

ScanBand v0.2

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.

First Outside Critic Presentation

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
