Getting started with Demand Evolution multi-touch displays

Here we will provide our users with the information they need to get up and running on Demand Evolution displays. If you are completely new to multi-touch, then it's probably best to start with the basics, where we explain the nuts and bolts of what multi-touch interaction is all about and explain a bit about how it works. If you are interested in developing multi-touch software, then you should head over to the developers section, where we can point you in the right direction for finding software SDKs, tutorials, and further documentation for implementing multi-touch applications. Note, these pages are being worked on continuously in an effort to help people out the best we can, so come back later if you want to read more, and feel free to get in touch with us if you have any questions or suggestions for helping people out with multi-touch.

Built for open source

The Demand Evolution displays are currently targeted at solutions developers and people who are comfortable with configuring and running open-source software from around the web. We have specifically chosen our hardware components in order to support the open-source multi-touch libraries available today, so beyond the initial setup of the hardware, we will direct you to the various multi-touch library projects for further installation and setup information.

The Gecko

If you have purchased the Gecko, then you need to connect the power cable, connect display to your computer's DVI port (remember it requires a dual-DVI connection to support its high resolution), and connect the built-in multi-touch sensor (IR camera) to your computer's USB port (shown below on the Gecko's back panel). Now you are ready to install the drivers and software.

The Kit

If you have purchased a kit then you will need to start by deciding how you will arrange your multi-touch screen, projector, and multi-touch sensor. If you purchased the adjustable stand then you should first screw together the stand and mount the screen. There is little construction necessary, and once mounted the stand allows you to easily adjust both the height and angle of your screen. If you are planning on building your own stand or mounting system for the screen, then you can start by just propping it up on a table top.

Once the screen is mounted you should place your projector behind the screen and while projecting an image from your computer adjust the screen and/or your projector settings to get the image to fill the screen. If space is tight feel free to use a simple mirror to reflect up to the screen so you can bring the projector closer, or you can opt to purchase a short-throw projector that can fill the screen from only a few feet away.

With the screen mounted and the projector aligned correctly, you are ready to setup the multi-touch sensor (IR camera). So connect the power cord to your screen to illuminate it with IR light, and connect the IR camera to your computer's USB port. At this point you are ready to get started with the software. If you are brand new to multi-touch then we suggest you start with the latest release from the NUI Community, where can be found here:
