WELL A BEEPING DEVICE WOULD BE UH FURTHERMORE THE LEARNING TIME IS A PROBLEM UH THIRTY FOUR THIRTY FOUR PER CENT UM THINKS IT'S IT'S TOO UH TOO DIFFICULT TO LEARN SO THE THE LEARNING CURVE SHOULD BE VERY SHORT UH FOR THE DUMBEST PEOPLE SHOULD BE ABLE TO USE IT I THINK OUR UH USER UH EXPERT SHOULD ALSO CONSIDER MANUAL A MANUAL FOR THE REMOTE OF COURSE UH I DIDN'T READ IT OH ALRIGHT USERS TO UH ADD ONE DO YOU THINK I DON'T THINK YEAH MM-HMM YEAH ALRIGHT BECAUSE THEY DON'T USE IT ALRIGHT YEAH RIGHT AND IT SHOULD BE CONSISTENT WITH CONSISTENT WITH OLDER REMOTES YES OKAY ALRIGHT YEAH RIGHT IT SH IT SHOULD BE THERE THE MANUAL BUT BUT NOT TO EXPLAIN HOW THE REMOTE WORKS ONLY SO IT'S BETTER TO UH PUT OUR ATTENTION TO THE THE DESIGN SO YOU CAN PICK UP AND USE IT THAN I THINK HMM YEAH RIGHT RIGHT SO NO NEVER MIND NEXT POINT UM R. S. I. WELL THAT'S ABOUT TWENTY PER CENT I THOUGHT BUT UH THE DESIGNER SHOULD UH TAKE IT UH SHOULD UH WIE ZEG IK DAT YEAH CONSIDER THE CONSEQUENCES OF USING YOUR REMOTE IT SHOULD BE A GOOD IN YOUR HAND MM-HMM YEP RIGHT THIS IS THE MOST IMPORTANT PART UM WE'RE LIKE THE REQUIREMENTS SAID WE'RE GONNA SPECIFY OF WE'RE GONNA TARGET A YOUNGER AUDIENCE UM THAT'S ABOUT SIXTY PER CENT OF THE MARKET SO IT'S UH QUITE IMPORTANT UM RESEARCH SHOWS THAT THEY LIKE TO HAVE A LITTLE L. C. D. SCREEN ON THEIR ON THEIR UH ZAPPING UH DEVICE UH I THOUGHT IT WAS THE AGE BETWEEN SIXTEEN AND TWENTY NINETY NINE PER CENT OF UH THE PEOPLE LIKE THAT SO IT'S VERY IMPORTANT WE SHOULD DEFINITELY HAVE THAT IN OUR UH DESIGNS WELL WITH TWELVE EURO FIFTY AS PRODUCTION COST WE CAN'T UH AFFORD AN L. C. D. UH YEAH BUT THEY THINK IT'S REALLY IMPORTANT SO IF WE WANT TO S IF WE HAVE A BIG IF WE MAKE LOTS OF UH OF THE STUFF MAYBE WE CAN UH BUY IT VERY CHEAP I DUNNO WE HAVE TO UH WELL WE'LL UH CONSIDER IT UH WE'LL THINK ABO WE'LL THINK YEAH I DON'T KNOW I DON'T HAVE ANY INFORMATION ON THAT SO RIGHT AND UH ANOTHER THING IS UH SPEECH UH RECOGNITION THEY ALSO LIKE THAT BUT RESEARCH IS VERY UH COSTLY SO YEAH BUT IT IT MIGHT BE IMPORTANT FOR THE SALE IT'S NOT YET A STANDARD UH DEVELOPMENT UH THOSE SO WELL I DO THINK L. C. D. IS MORE REACHABLE THAN THE SPEECH RECOGNITION SO WE MIGHT CONSIDER L. C. D. SCREENS NO ALRIGHT 'KAY UM I THINK THAT'S IT UM I THINK IT IS SENSIBLE TO U UH TO TAKE THIS TAKE THESE POINTS INTO THE NOTES YES WELL YOU I C I CAN UH STILL SEE YOUR PRESENTATION YEAH RIGHT YOU UH GOT UH OH YOU GO YES WELL GO AHEAD WELL UH IT IS MY TASK TO UH EXPLAIN UH OR TO POINT OUT A WORKING DESIGN YIP WE HAVE THAT HERE OKAY HOW DO YOU ENLARGE IT SO THAT YOU CAN HAVE THE F. F. FIVE F. FIVE YEP WELL THE WORKING DESIGN THAT'S MY UH NEXT BUTTON WELL ALRIGHT UH YOU KNOW WHO I AM AND WHAT I DO SO UH WE HAVE THIS IT'S A BIT UH UNCLEAR BECAUSE I WANTED TO COPY PASTE SOMETHING IT WAS ORIGINALLY IN BLACK AND WHITE BUT IT BECAME BLACK AND PURPLE BUT I THINK YOU CAN READ IT UM WELL UM I THINK IT'S IMPORTANT UH FOR YOU TO REALISE THE BASIC FUNCTION OF A REMOTE CONTROL UH WELL YOU CAN SEE UH SO IT UH INVERTS AND I THEN CAN SELECT I CAN SELECT ON THE DINGS IT GOES TO THE NEXT PAGE NAH UH NEVER MIND YEAH GO AHEAD YOU HAVE UH BASICALLY UH THE ENERGY THE POWER OF THE OF THE REMOTE CONTROL UH AND THE SENDER W WHICH IS THE LED THE THE THE THE THE THE THE THE THE BULB THAT SENDS THE THE INFRARED BEAM TO THE NO TO THE SET AND UH THE SOURCE IS OF COURSE THE USER UH THE USER INTERFACE IS UM UH THE THE THE BUTTONS OF COURSE AND THE THE USER INTERFACE SENDS UH THE THE DIFFERENT SIGNALS OF THE DIFFERENT BUTTONS TO THE CHIP AND THE CHIP UH SENDS IT TO THE LED AND THE LED SENDS IT TO THE RECEIVER THAT'S THE THAT'S THE BASIC IDEA VERY BASIC UM WELL I HAVE UH UH PUT IT IN A IN IN IN A A COUPLE OF BASIC STEPS UH THE REMOTE UH IS BASICALLY JUST WAITING FOR A USER TO PRESS A KEY IT DOES NOTHING UNTIL UH OF COURSE UH THE KEY IS PRESSED THE KEY A SIGNAL TO A CHIP UH THE CHIP SENSES THE CONNECTION UH AND RECOGNISE THE KEY SO WELL YOU UNDERSTAND THE CHIP UH PRODUCES MORSE CODE UM A SPECIFIC CODE TO INDICATE THAT SPECIFIC BUTTON THAT IS PRESSED OF COURSE AND IT USES TRANSISTORS IN THE IN THE REMOTE CONTROL TO AMPLIFY AND TO SEND UH THAT SIGNAL AGAIN TO THE TO THE LED WHICH IS THE BULB OF COURSE NOW THE LED PRODUCES AN INFRARED BEAM AND SIGNALS THE WELL IT'S UH VERY SIMPLE AND SIGNALS THE UH SIGNALS TO THE SENSOR ON THE T. V. SET AND THE T. V. SET UH ALSO RECOGNISES THE THE THE SIGNAL AND PERFORMS THE ASSIGNED TASK SO IT IS ALSO WHY WE HAVE TO HAVE A BUTTON THAT SAYS UH I'M NOW BUSY WITH A D. V. D. UH IF WE HAD DONE THAT AND A BUTTON FOR T. V. SO EXACTLY UH WELL THIS IS UH THE BASIC UH FUNCTION OF A REMOTE I'VE SOME COUPLE OF PICTURES HERE IT'S A VERY BASIC ONE AND UH IF WE IF WE'RE GOING TO ADD AN UH AN UH L. C. D. SCREEN TO IT IT UH WON'T LOOK ANYTHING LIKE THIS BUT THIS IS VERY BASIC UH BASICALLY THE THE SHAPE OF UM OF A REMOTE CONTROL IT HAS UH VERY LITTLE BUTTONS AND BUT IT IT UH IT'S IT'S QUITE UM YEAH YOU CAN EASILY RECOGNISE THE BUTTONS THEY'RE UH FAR ENOUGH APART AND AN ANYTHING IT'S NOT VERY UM HIGH TECH UH IF YOU LOOK AT THE SHAPE IT'S UH JUST A SIMPLE LONG BOX UH SHAPE SO WE HAVE TO UH CHANGE A LITTLE BIT UH TO THAT UH SO THAT UH IT BECOMES MORE USER FRIENDLY AND THAT UH PROBLEMS LIKE UH R. S. I. AND UH THOSE KINDS OF THING DON'T DON'T OC DON'T OCCUR YEAH UM I HAVE A TABLE HERE ABOUT UH THE L THE RELEVANCE OF THE BUTTONS UH THE POWER BUTTON IS USED VERY MUCH CHANNEL SELECTION VOLUME AND TELETEXT WELL TELETEXT IS NOT AN OPTION SO THAT UH BUT I THINK IT'S VERY IMPORTANT TO MAKE UM THE POWER CHANNEL AND VOLUME BUTTONS UH NEAR TO THE THUMB SO YOU CAN'T HAVE R. S. I. UH CONSEQUENCES RIGHT MAKE THEM BIG MAKE THEM EASY TO UH TO PRESS RIGHT YEAH RIGHT RIGHT
