'Kay , this is where I went a bit mad with PowerPoint so. What  the first thing  question I asked was what are we trying to design ? Well , a device which basically just sends the signal to the T_V_ to change its state , whether that be the power , or the channel um or the volume , everything is just um some sort of signal to change the state of the T_V_ or other appliance that it's sending the signal to. Um , so I decided I'd have a look at what th other people have designed and try and take some inspiration from that. But uh although we will want to be taking ideas from other people , we wanna make sure that our design stands out and I thought that was something that  well it wasn't really my area because  I'm dealing with the inside really. So um , yeah I ran out of time so I couldn't do this one as fun as the last one .
Um and uh  I found out that most uh controls use some form of infrared to send signals to the T_V_ presumably because of the cost issue of uh something like uh the same thing that computers use , wireless and , you don't need to send very much information. Um , most of them are powered by some form of battery. Now our one , I'm I'm not sure whether we want to look at the size issue because most of them are powered by triple A_ batteries but those can be quite bulky so I d I didn't know if you wanted to look at something else um so we could shrink down the size of the control.
Mm-hmm. Could I  can I interject to ask a question there ,
Mm-hmm.
