We've recently expanded our Student Kiosks from 4 to 9 kiosks around campus. These are custom Kiosks I designed and used our University Fab Shop / Paint Shop to create for us. They use a 19" LCD and a stadard desktop computer with an add on wireless card and wifi extender antenna to get better reception. Systems are really just setup for quick internet / email / registration info for students.
The kiosks have been very popular and according to our domain stats from last year, the 4 kiosks we had in place averaged 30 unique logins each per hour during normal business hours, higher than any other student stations on campus.
