Limitations of ICT and future advances

1. Limitations of ICT and future advances 3.3.4

2. The aim of this presentation • 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. Introduction • 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. Mobile Phones • 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…

5. Mobile Phones

6. Mobile Phones • 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. Mobile Phones • 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. Advances in mobile phones • 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. Life in colour… • 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. What a drain… • 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. Snap it! • 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 • Smart Phones are increasingly popular with their touch screen displays, WiFi and 3G connections… • But all this requires even more power!

13. So what is the limitation of mobile technology? • 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. Thing to remember… • 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. So what does the future hold? • 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. Wireless Charging • 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. Small devices…small screens • 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. >>> Speeeeeeeeed • 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. >>> Speeeeeeeeed • 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. Security • 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. Biometric data • 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. Biometrics online • 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. Problem with current technology… • 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. Summary • 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. Example Questions • 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.
