Snail 3-d location project software

Purpose

The software analyses the motion of a single snail moving in a tank and reports its position in x,y,z coordinates. A single video camera is used to record two images, one direct the other trough a mirror. AVI-format Videos of the snail are recorded (see example) analysed trigonometrically to record the position. An example analysis can be browsed here.

The details of the software have been accepted for publication in Behavior Research Methods, Instruments, & Computers.

Equipment required

The software was developed on a 486 DX 33 MHz PC with a Cirrus Logic™ 256 color board running Windows™ 3.1. It should run on any Windows 3.1 PC with 256 or more colors which has the Video for Windows™ run-time. See Below for how to get the required run-time library from one of the Winsite/ CICA mirror sites. 2Mbytes of RAM should be enough; it runs happily on 4Mbytes.

Obtaining the Analysis software

The analysis software is available here for those who have the Video for Windows runtime and who wish to try it out! The package includes When you unpack the Zip file, use Winzip or PKunzip with the -d flag to preserve the directories!


If you don't have the Video for Windows run-time, then you can download the files

The original runtime (which we used in development) is here in the UK and also in the USA.

It also works with the latest 1.1e runtime which is here in Europe and in the USA
