Here is one although it involves a change of mindset and some outlay. Place under the table before each player a mobile device. Thia device consists of a touchscreen and a link to the other machines. The touchscreen consists of buttons describing common calls - "natural", "conventional", "transfer", "takeout", etc. After partner makes a call you touch the approrpiate sections and these are displayed on the opponents' displays. Very simple, easy and intuitive. Nige has also suggested something along these lines, albeit without the tech. Of course, even if everyone thought this would be a good idea it would be a very long time before anyone would even consider introducing it - and no doubt many would object to such an approach. But an answer using technology is not so difficult. It says something of the mindset of the bridge authorities that such ideas seem to be a million miles from the table; whereas in most other major activities the idea of innovation and/or technology is discussed much more actively. That seems to me to be a mistake....but then at under 50 I practically count as a junior player!
Like video and other technology in football, this will be booted into touch on the grounds of cost, and of slowing down the game.
