Mm-hmm.
The design should minimise R_S_I_ and be easy to locate and we were still um uh slightly ambivalent as to whether to use voice recognition there , though that did seem to be the favoured strategy , but there was also , on the sideline , the though of maybe having a beeper function.  Okay , so we can come back to that slide , if you don't have a note of those. I'll just show you how we're going to evaluate our own feedback to this , to what we have so far. We're going to use a seven point scale , where one is true and seven is false. We look at each of those criteria that I've just mentioned , I'll call that slide back up ,
Yeah.
and I will just do a preliminary rating of all those criteria on the whiteboard here.
