A technique is directed to interfacing a user to an online meeting. The technique includes performing an evaluation operation on a set of input/output (I/O) devices available for use by the user during the online meeting, each I/O device of the set being constructed and arranged to perform a same I/O function. The evaluation operation assesses online meeting performance of each I/O device of the set. The technique further includes selecting an I/O device based on a result of the evaluation operation. The technique further includes involving the selected I/O device of the set in the online meeting and excluding a non-selected I/O device of the set from the online meeting. Accordingly, the best suited I/O device can automatically be selected to improve the user experience. In some arrangements, rather than automatically switching I/O devices, the user is automatically prompted with a recommended I/O device to use.
