2  You will need to be able to Explain the limitations of using ICT in society today and how advances in technology may overcome some of those limitations.  The text book has a list of limitations and possible future advances to address these limitations.  This presentation will look at some of those limitations and advancements.

3  We already know that ICT is wicked…that why we study it!  However, we need to be realistic…  Technology is not all its cracked up to be…  By understanding the limitations of ICT we can start to develop better technology to address these problems!

4  I got my first mobile phone when I was in year 11…  And over the years my phones have changed a lot…  The next slide shows the phones which I remember owning…there are a few missing but I can’t remember what I had!  They will pop up in chronological order…

6  My first phone…the Philips C12…was a great little phone. It has a screen which allowed me to read 2 lines of a text message…  And it also let me make calls.  I think it had an alarm too! Cool huh?

7  The battery was ok…but there was a problem…  If you didn’t let the phone run right down on the battery, when you charged it up the battery life would get shorter and shorter!  This was a serious problem and something had to be done!

8  New types of battery technology was introduced which allowed batteries to be charged up whenever you wanted!  The batteries also charged up faster!  Also…the screens got bigger!  And you could play games…like snake!  No colour yet though…

9  My first mobile to have a colour screen was the Sony-Ericsson T610.  Problem was…the larger, brighter and colourful screen resulted in lower battery life!

10  As the popularity of MP3s increased the type of mobile devices you could buy changed too.  My Sony-Ericsson W550i Walkman phone was cool…but again…the battery was a problem.

11  Phones became even more advanced with the addition of high mega pixel cameras.  This meant that phones needed more power and more storage space!

12  Smart Phones are increasingly popular with their touch screen displays, WiFi and 3G connections…  But all this requires even more power!

13  To be mobile you need to be disconnected from a power source…  And the more technology you cram into a mobile device the more power hungry it will be.  Over the years I have had phones which have had really good battery life (up to 5 days without needing a recharge)…  …to phones with poor battery life but with loads of cool features (I charge the iPhone every day now).

14  Its not the batteries which are worse…  The batteries are fantastic now…  Its just they have to power a lot more features meaning they are working harder!

15  Better batteries that can cope with the increase in power demands?  Solar recharging mobile phones?  Kinaesthetic charging (like the watches that charge using the movements in your arm)…  Or how about wireless charging?

16  This is a possibility.  Scientists have discovered a way of powering devices using Resonant Induction technology…  If all buildings used this technology your devices would always be powered.

17  Although smart phones have larger screens that their predecessors…  Their screens are still too small for viewing webpages and sometimes even films.  OLED technology is being developed which will allow screens to bend without distorting the image…  Perhaps this will mean we can have folding screens which we can unfold when we want to view something slightly large?

18  We can already stream media over the internet.  We do it on youtube, BBCs iPlayer and also iTunes.  However, we can’t stream full HD quality films because the UK’s infrastructure simply isn’t good enough.

19  Most broadband houses in the UK are able to get up to 2Mbps connections.  Some houses up to 8Mbps connections.  We wont be able to stream full HD films unless we improve our infrastructure so that we can get household speeds of up to 100Mbps.

20  At the moment we need to remember our pin numbers to pay for goods in a shop.  Paying online is easier (unless you have set up the additional security check requiring you to enter in your pin number).  But wouldn’t life be easier if we could use a finger print or eye scan as a way of paying?

21  Imagine paying for your goods using your finger prints…  At the end of the shop, you press your finger onto a scanner and then you walk away…  You could theoretically do away with your cards…each finger could represent a different card!

22  You could also pay for goods online using the same system.  You can already buy keyboards with finger print scanners on them (used to unlock your computer).  You could easily use that same keyboard to pay for your goods online.

23  Fraud has been made easier because of technology.  If you know someone’s pin you can pay with their card.  If you have someone’s card you can buy something online!  Using biometric data would make stealing people’s money a lot harder… › I don’t think many shops would accept a cut off finger as a valid method of payment…so don’t even try thinking about stealing a finger!

24  There are lots of limitations of current technology…  There are also lots of examples of news articles that talk about current problems.  You need to research into other limitations. Most of the time, the articles will also talk about the technology which aims at addressing these limitations.

25  Explain the limitations of entertainment systems within cars and how developments in technology may overcome these limitations.  Explain the limitations of using electric cars instead of petrol powers cars and what developments in technology are needed to keep electric cars on the road.
