Is the new system based on a touch screen, like some ATMs?
No. The voter uses a rotary wheel to navigate through the ballot and select his or her vote. This interface is based on medical research and was chosen because it is more durable and not prone to calibration issues as in touch screen systems and gives voters with disabilities a range of accessories to support different needs. The eSlate has a paper trail that allows voters to confirm their choices on a printed record. The printed copy is viewed through a clear cover on the printer that ensures no one can tamper with the ballot or remove it from the unit.
