An information kiosk answers the questions people would otherwise ask a member of staff: where is it, what is on, which floor, how do I get there. The hardware decision follows from how the screen will be read. A map viewed by a family from a couple of steps back needs a large screen; a staff directory used by one person at a time does not. Then decide where it goes: standing in a concourse, fixed to a wall by the lifts, or built into a table.
All-in-One Information Kiosks (view the range) list screen options of 21.5, 32, 42, 49, 55, 65, 75, 85 and 98 inch, with 10-point infrared or PCAP touch, a metal housing with an aluminium alloy frame and tempered glass front, an anti-theft lock, Windows or Android configurations and Wi-Fi or wired (LAN) networking. Wall-mounted, floor-standing and touch-table formats are available, and which sizes are offered in which format is confirmed with your quotation. For the table format see Interactive Touch Tables (view the range).
The kiosk is a touchscreen computer. What makes it a wayfinding point is the software and the content: maps, directories, search and the way information is kept up to date. We scope that around your site and quote it separately from the hardware. See wayfinding for how a project is put together.
