Great .
Okay so um while uh researching this this topic I first of all just thought of a couple of things that I would like to see in a remote , and just uh looked to see if they're actually available in any current remotes , and then also searched for which are the top-rated uh remote controls on Epinions dot com , which is a a you know a a customer um written basically review site. So um there's a pretty wide range of uh remote controls these days and and uh this remote control on the right here is is one of the more extravagant , but it's not really  it's by no means uh mm you know  on it's own in being so expensive. There are a lot of expensive remote controls out there.
Looks like a P_D_A_  ?
So   yeah it doe it's  well basically all the functions uh are controlled through through the L_C_D_ screen except for the really really kind of main functions , which have a couple of of their own buttons. Um and if you look at a lot of the universal remotes out um on the market , I know we're working on television remote , but a lot of the universal remotes out there have uh have these L_C_D_ screens which kind of helps when you're using multiple uh devices I suppose because you can have multiple kind of functions  d different functions on the screen at different times. But um the thing that I find most interesting about this remote control , and it's kind of difficult to uh to see in the slide , but it has a scroll wheel on it , which is kind of like uh a mouse scroll wheel , which I think is  it's a really kind of important design aspect um is  it's  'Cause the thing is what a  what we  the presen this presentation we had is what we want the remote control to actually do. And obviously the the simplest thing that a remote control does is it just change the change the channel.
