You can log the user activity details in new table. for example when user start this activity you can go and check whether any other user active or not by using table data. if there is no active user, you can insert new record with details like, user id, activity start time etc..
if user already active you can show message to new users that already another user active on this activity.
When user finish the activity you can go and updated the record by using another column. There will be a issue when the user disconnected while activity in progress. You may need to have activity timeout to handle that.
