Frequently Asked Questions

Q. What joysticks can or should we use in conjunction with CARMA?
A. Although many types of joysticks will be correctly detected by Windows and usable in CARMA, including video game (e.g., Xbox 360) controllers with thumb-size joysticks, a full hand-size joystick is recommended. One affordable and comfortable option that several projects have used is the Logitech 3D Extreme Pro joystick.

Q. Can CARMA be configured to rate only segments of a multimedia file?
A. Currently, CARMA requires the entire file to be rated. The ability to select a start and end time may be added in the future, but in the meantime it is relatively simple to trim a larger multimedia file into smaller segments using free software, such as HandBrake.

Q. I am unable to install CARMA using the standalone installer. What gives?
A. Make sure the installation file (.exe) is extracted from the archive file (.zip) before it is run. This file should also be stored on the local machine (i.e., not on a remote server) that has internet access. Of course, users will also need the privileges required to install a program in the first place.

Q. Why do I sometimes get a "timer callback error"?
A. Two steps usually resolve this problem. First, if you are loading large media files from an external device or remote server, copy these media files to the local machine and load them from there instead. Second, update the affected computers' drivers, especially those for the chipset, USB controllers, and graphics card. If these errors persist, contact me using one of the two options below.

Q. Why does the Collect window tell me to install VLC? I have VLC installed!
A. This error means that CARMA cannot connect to your version of VLC. This problem is usually caused by one of three issues: either your computer does not have VLC installed after all, your computer has the 32-bit version of VLC installed, or the ActiveX plugin was not installed along with VLC. All three issues can be resolved by reinstalling the 64-bit version of VLC and making sure that the ActiveX plugin option is enabled (i.e., checked) during installation.
