Yes. Simultaneous interpreting requires a huge cognitive effort on the part of the interpreter and they need to use both their sense of hearing and sight to ensure they are Abe to interpret effectively. Ideally, interpreter booths should be positioned with a clear line of sight to the stage. However, in smaller venues this may not be possible in which case, a video feed and large screen monitor will be needed. For remote simultaneous interpreting, both a video and audio feed will be required.
