CUClickers / i>clickers - Accessibility

Service Overview

CUClickers is an audience response system used to facilitate active learning and enhanced assessment in the classroom.  It uses the radio frequency-based iClicker system, which is non-directional (meaning the remote doesn’t need to be pointed toward the receiver).  Students use iClicker remotes to vote on questions the instructor poses to the class. Instructors operate iClicker using software on their computer and an iClicker receiver (base station).  

iClicker Accessibility Status

No known accessibility issues exist when using the handheld clickers. The clicker registration web page has not yet been tested for accessibility.

Information for Users with Disabilities



Student iClicker remotes (clickers) are available at the bookstore.  The version of iClicker used most commonly on campus is the iClicker+.  A haptic version of the iClicker+ is also available that vibrates to confirm status changes like submitting an answer, turning on the device, or setting the classroom frequency.  The haptic iClicker is available for purchase by emailing and is recommended for students with visual disabilities.  


Students need to register their iClicker by associating the Remote ID on the back of the remote with their name and IdentiKey login in the iClicker national database. Students should register their devices by following the iClicker student registration tutorial.  Make sure that the “Student ID” field is filled out with your IdentiKey login name.  Students with visual impairments may need assistance reading the iClicker Remote ID, as it is not written in Braille or raised letters.

The Device:

All iClicker+ remotes have five buttons on the front (A-E, printed and in Braille), as well as a power light, a low battery warning light, and an additional light next to each of the five buttons.  The power light is always green, and the low battery light is always red. The five lights near the buttons may either be red or green.

Using the Device:

To use the device, the student turns on the iClicker using the round power button at the top of the device.  At that point, the lights next to the letters will light up to show the user which frequency code the iClicker is set to.  Each room has a frequency code posted on the wall that students will need to set on their clicker. The room code can be set on the iClicker by holding down the power button for 2 seconds and then typing in the room code.

Votes are made by pressing the button corresponding to the appropriate letter, and the corresponding light will blink green to indicate the answer was received.  A steady green light next to an answer option button indicates that your vote was received, while a blinking red light indicates that your vote was not received. The haptic iClicker vibrates when a vote is successfully counted. Some students with mobility impairments might not be able to operate the iClicker buttons effectively and may require assistance.


The Software:

The iClicker software must be downloaded from the University of Colorado OIT website in order to interact with Canvas. Once the software is downloaded, it needs to be configured, either to stand alone (without interaction with an LMS) or to work with Canvas. Grade options and the room frequency code need to be set.

Instructors who use assistive technology should use the iClicker Cloud software (REEF) rather than the desktop iClicker software.

Information for Instructors

If students with visual impairments are enrolled in your course, it is important to read aloud the classroom frequency code at the beginning of the class. Additionally, read aloud any warnings the iClicker software generates during polling, the text of each question, and the answers for each question along with the corresponding letter for each answer option. If a question requires students to view or interpret a visual stimulus, such as a graph or image, make sure to describe the image as you read the question.

If students with accommodations for extra time are enrolled in your course, make sure to use the count-up timer (rather than the countdown timer, which automatically closes polling) so that all students have adequate time to vote.
