Um  the the controls themselves tend to use a very inconsistent colour scheme. Um for instance , the stand-by button isn't always red , uh it really should be. It's uh something the user then uh identify with. This is a red switch off , that's how it should be. Um I'm not sure if there's any other examples of that , but something to look out for. Um there's a problem that I've I've got couple of preferences for the the end control  um I get 'em with the the red colour button for stand-by and s the other examples of that  um   The buttons should be large. They shouldn't be tiny little things like you get on some mobile phones. They should be easy to press , very comfortable.  Um one of the examples given on the homepage was um  there's an up and down volume button but both of them have a V_ on them ,
Mm-hmm.
so the up volume button looks like it should be a down volume button , that's kinda confusing. Um should avoid s things like that. Um  if the the corporate colour scheme allows it we should have a very bright colour so that it can be easily identified anywhere.
Okay.
