Um
other  we've also got to remember that this is a device that serves as a useful purpose . Uh we want people to be able to use it s as a remote control , so we need to determine what the essential functions of the d of the device are and make sure that we include  that we've included all of those and that we actually end up with a device that is going to be useful to people .
We have a number of different choices for a design concept um and s that's that's something that that I'll show you some examples of um , but essentially we need to choose how how is this device going to work , how how  what kind of model is there going to be for user interaction with this device . Uh once we've chosen a a concept for it , we can then design the features around the concept , making sure that we get all the essential functions in the device and uh the extra functions and the more advanced features . And of course we also have to make it look cool .
So basically , that's what we don't want .  M we don't want lots of buttons , uh complicated features . We want something that looks nice and simple .
Here's a a fairly simple device . This is an an iPod from Apple . Um I think the main thing to notice about it is it just has four buttons . It's very minimalistic in its design . Uh you use these four buttons to m to move around a range of settings on the small L_C_D_ screen . Um  the thing I like about this is that
Hmm .
it's very very quick to access the main features . Uh you can just about make out uh that the button  three buttons are uh previous track , next track and play pause . They're the main the main features of the iPod , the things you will use a all the time . Um then if you want to do anything more advanced , you go into the little menu on the L_C_D_ screen and you use the buttons just to scroll around and and find the more advanced features that you want . So I think that's that's a good a good kind of model that we could have . Um
 here's a another example . This is uh  it's an interesting idea and I think i it looks pretty cool . Um it's certainly got novelty value . Uh it's nice and colourful , it's nice and bright . Uh it's also something that you can kind of feel your way around . The buttons are are different shapes and and you can sort of  yeah if you're watching T_V_ in the dark or whatever , you can work out which button's which and basically , yeah it's ith it's fun .
Mm .
So I  I like I like this idea of just having buttons for the features that you use most often . So you'd need a few buttons to select your favourite channels . I mean most people , when they watch T_V_ , they have two hundred and fifty channels on their T_V_ and they watch of 'bout four of them at the most . So , you have buttons for your favourite channel , changing the volume , which is something you do all the time when you're watching T_V_ , and the button to switch it off , in case you get bored .
Um other features , things like adjusting the brightness , tuning the T_V_ , uh I don't know what else you do with a T_V_ . Um but these are these are all necessary functions . Uh you can't have a t there's no point having a television that you can't tune or that you can't set the contrast , so we need to find a way of including these somehow . Um and one other suggestions I'd make is to in is to include in a menu system , a bit like on the iPod .
