Controlling assistance information comprises determining a user mode based on computer input signals generated by a user. If the user is in a passive mode and assistance information is detected, the assistance information is disabled in response to detecting a hidden signal. The assistance information is then enabled if later a reset signal is detected. If the user is in passive mode and assistance information is not detected, the assistance information is enabled in response to detecting a trigger signal. If the user is in an active mode and assistance information is detected, the assistance information is disabled.
