Hardware - fmsbeekmans/jest GitHub Wiki

The Hardware made available by Gemeente Delft is a PC (HP Z400) with 12 GB memory and a Quadro video card, a large television that comes with a touch overlay panel, the Samsung TM55LBC, that detects up to 6 points at the same time.

The television is embedded in the surface of a large table, with restricted access to the screen at the short sides of the table.

Because the touchscreen is driven by infra-red (IR), the screen is also sensitive to hovering slightly above the screen. In combination with the horizontal orientation of the screen, this causes a noticeable discrepancy between where a user pushes and where the input is registered by the hardware. Since touch input is registered before the user touches the screen, the user can get visual feedback before tactile feedback. The application will have to be designed with these quirks in mind.
