Emerging Technologies

  2. 2. Technology and our lifestyle ● People can work on the go ● Positive impacts ○ Online banking, shopping, social networking, etc. ● Negative impacts ○ Working outside office hours, gaming addictions, etc. 2
  3. 3. Discussion Point Research the first organ to be grown and transplanted using tissue engineering. What do you think about scientists using technology in a laboratory to grow body parts to order in this way? 3
  4. 4. Three-dimensional printing ● Three-dimensional (3D) printing is where an object is created based upon a blueprint made with modelling software. ● It works by taking thousands upon thousands of cross-section layers of the model, from the bottom to the top, to create the object. ● It used heated plastic to print a single layer at a time. ● It takes a very long time to produce an object 4
  5. 5. Fourth & fifth generation cellular communications ● The 4G provided two main benefits, increased upload and download speeds and reduced latency. ● 4G enabled the smart phones get a quicker response time improving the the experience of streaming online video and playing online games. ● The 5G technology is reported to be 100 times faster than 4G technology. ● 5G could provide speed of 800 Gbps, meaning that 30 high definition movies could be downloaded in a single second. ● The important advancements may include - location services, weather, multiple people in video conferencing calls, self driving car, etc. 5
  6. 6. Artificial Intelligence ● Artificial Intelligence (AI) is when a computer is able to make decisions based upon stimuli, much as human would. ● AI systems are made from heuristic knowledge using programming rules. Heuristic: discovering knowledge through experience 6
  7. 7. Discussion Point Many people find the concept of allowing a computer to be responsible for major tasks, such as driving a car, an extremely scary prospect. What do you think about placing your life in the hands of a computer? 7
  8. 8. Augmented reality ● Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real world are enhanced by computer-generated perceptual information. ● Imagine using your phone’s camera to take a picture of a sign in a foreign language you can’t read. The camera uses image processing to understand what it is written on the sign. It then uses a translation tool to translate the sign into a language you do understand it. 8
  9. 9. Discussion Point Find out about Microsoft’s augmented reality product the HoloLens. What impact could this product have on a person’s life? 9
  10. 10. Biometrics ● Biometrics is the use of technology that tracks user values. ● This could be as simple as their heart rate with fitness devices, ot it could be voice recognition software, fingerprint and iris recognition or even pattern recognition of DNA patterns. 10
  11. 11. Cloud computing ● Cloud computing is where a collection of servers are used to store or process data instead of doing this on your own computer. ● Your computer simply needs an internet connection in order to communicate with the bank of servers. 11
  12. 12. Computer-assisted translation ● Computer-assisted translation tools work by giving the software either a document or a string of text. ● The software then removes anything that is not text, such as pictures or tables, and simply takes what is left over and translates it into the language of choice. 12
  13. 13. Holographic and fourth generation optical data storage ● Holographic data storage is a developing medium of high capacity data storage. ● It can store bits in parallel, meaning many bits are stored layer upon layer. ● It will bring about the potential to hold up to 1 TB of data on optical media. 13
  14. 14. Holographic imaging ● Holographic imaging (Holography) is a 3D image that is created with photographic projections. ● It is a free-standing 3D image that you can see around. 14
  15. 15. Discussion Point How could the introduction of holograms that can be transmitted into our home change the way we live? 15
  16. 16. Quantum cryptography ● Quantum cryptography is one of the safest methods to encrypt data which uses physics. ● The process of encryption is carried out in a similar way to mathematical algorithms, in that it uses a key. ● This key is generated using photons, which are tiny packets of light. The key scrambles the data. The data is transmitted using fibre optic cable. 16
  17. 17. Quantum cryptography 17
  18. 18. Robotics ● Robotics is the creation of computers that perform tasks that humans cannot or are less efficient at performing. ● A robot works by having a processor that control its movement. ● It has sensors attached to it and programmed accordingly to do a set task. 18
  19. 19. QR Codes ● Quick response (QR) codes are type of barcode that is made up of black and white squares. ● They are printed on many products in order to give extra information about the object. ● It is scanned by a camera to carry out a certain action. 19
  20. 20. Wearable computing ● Wearable technology can take many forms. ● However, there are two major forms with which most people are currently familiar. ● These are fitness devices and smartwatches. 20
  21. 21. Ultra-high definition television ● Ultra-high definition is now firmly established in screen and monitor definition. ● This refers to the measure of the horizontal number of pixels for the screen. ● The ultra-wide screens (2560x1080) and standard desktop monitors (1920x1080) both count as 2K, which is classed as HD. ● The 4K and 8K are also available. 21
  22. 22. Vision enhancement ● Vision enhancement is normally provided in the form of a type of glasses or lenses. ● These alter the stimulus that enters through the eyes and filters it in a way that can enhance a person’s vision. ● The glasses or lenses can be tailored to the person and their current level of vision for greater effectiveness. 22
  23. 23. Virtual reality ● Virtual reality (VR) is where a 3D space is made by a computer. ● The user is then effectively put into that 3D space by wearing some sort of technology, usually a headset, which displays that space and their position within it. 23
  24. 24. Activity 11.1 Create a podcast about any of the emerging technologies. The podcast should include the following information: ● What is the technology? ● How does it work? ● What will it be used for? ● What impact will it have? 24
  25. 25. Activity 11.2 Learners listen to each other’s podcasts. They should create a report that, from listening to the podcasts, highlights the two emerging technologies they think are likely to have the most impact on: ● their own and others’ lifestyles ● organisations ● medicine ● the environment. In the report they should also explain why they think the technologies they choose will have the most impact. 25
