Documentation:Clickers/Remote No LCD Display
Q: Why don't i>clickers have an LCD display?
A: Two reasons: student cost and accessibility. The LCD screens available with competing clickers are often small and hard to read. Our inventors found that when students were focusing on their remote hardware, they were less likely to focus on the content but instead focusing on the technology. Moreover, the LCD display often does not offer sufficient light for dim lecture halls or students with mild visual disabilities. With the i>clicker remote, a green/red vote status LED light is much easier to see in dim lecture halls and is more friendly to students with visual impairments. A green light means not only vote was sent but also confirmed/stored. A red flashing light means the vote was not received.
