1 IOT POLY ENGINEERING Information is an essential resource for design (1 of the 7 inputs). 2.Communication technology significantly impacts the way we live. Communication Technology November 7, 2011 Main Ideas:

2 IOT POLY ENGINEERING 2-1 Into which column does each of the technologies below go? Telephone T.V. Remote Alarm Clock Thermostat

3 Into which column does each of the technologies below go? Telephone – a human speaks in one side, a human hears it on the other. T.V. Remote – a human pushes a button, a signal is send to the television. Alarm Clock – communicates the time (with a sound) to a human. Thermostat – measures the temperature and turns the furnace on or off.

4 Into which column does each of the technologies below go? Telephone – a human speaks in one side, a human hears it on the other. T.V. Remote – a human pushes a button, a signal is send to the television. Alarm Clock – communicates the time (with a sound) to a human. Thermostat – measures the temperature and turns the furnace on or off.

5 IOT POLY ENGINEERING 2-1 ASSIGNMENT 1 Instructions: Create the following chart. Fill it in with at least 8 entries in each column. Example technologies are on the next screen. HINT: with any technology, ask yourself what is communicating (human or machine) and what is getting the communication.

6 IOT POLY ENGINEERING ASSIGNMENT 1 - examples AutoCADGPS T.V. Text Msg. Video Game Controller Car Alarm Traffic Light Remote Car Locking Motion Sensor Light NOTE: Many technologies fit into multiple columns depending on how you look at it.

7 IOT POLY ENGINEERING 2-1 Technology has changed the nature of communication in our society. What are some ways contemporary communication impacts your life? Communication Technology

8 IOT POLY ENGINEERING 2-1 Worldwide market of cell phone users has outstripped all predictions. A world population of 6.9 Billion How many cell phones? First public trials of cell phone use in 1978 Communication Technology

9 IOT POLY ENGINEERING Billion Cell Phone Users Worldwide At end of 2007: 48% of World Population

10 IOT POLY ENGINEERING Billion Cell Phone Users Worldwide At end of 2007: 48% of World Population Is this exponential or linear? Does it look like a line? (It is exponential).

11 IOT POLY ENGINEERING 2-1 Cell Phone Users Worldwide What is Communication Technology?

12 IOT POLY ENGINEERING 2-1 INPUTS PROCESSESOUTPUTS GOALS FEEDBACK Control Communication Technology

13 IOT POLY ENGINEERING 2-1 –Goals Inform Persuade Entertain Control Manage Educate –Inputs Source of Communication –Processes (in this order) Encoder Transmitter Receiver Decoder Storage Retrieval –Outputs Message to the destination –Feedback and Control Reversing the communication line Communication Technology Not always

14 IOT POLY ENGINEERING 2-1 GOALS Communication Technology Inform Persuade Entertain Control Manage Educate

15 IOT POLY ENGINEERING 2-1 Communication Technology Transmitted Communication Input SOURCE Inform Persuade Entertain Control Manage Educate

16 IOT POLY ENGINEERING 2-1 Communication Technology Transmitted Communication Input SOURCE Encoder Transmitter Receiver Decoder Storage Retrieval Process TECHNOLOGY Inform Persuade Entertain Control Manage Educate

17 IOT POLY ENGINEERING 2-1 Communication Technology Transmitted Communication Input SOURCE Encoder Transmitter Receiver Decoder Storage Retrieval Process Received Communication Output DESTINATION TECHNOLOGY Inform Persuade Entertain Control Manage Educate

18 IOT POLY ENGINEERING 2-1 Telephone Communication One of the simplest devices in your house Microphone – converts sound energy of voice into electrical energy (encodes) Wires – the electrical energy travels from your phone, via exchanges, to your friend’s Receiver – friend’s earpiece speaker converts the electrical energy back to sound Answering Machine – friend isn’t home, and this machine stores your communication Play Button – friend gets home, presses play, hears your recorded voice

19 IOT POLY ENGINEERING 2-1 Telephone Communication One of the simplest devices in your house You speak into the microphone Input Processes Friend hears voice in receiver Output Encoder Transmitter Receiver Decoder Storage Retrieval

20 IOT POLY ENGINEERING 2-1 Telephone Communication One of the simplest devices in your house What part of this technology system is an example of Human to Machine communication?

21 IOT POLY ENGINEERING 2-1 Telephone Communication One of the simplest devices in your house What part of this technology system is an example of Human to Machine communication?

22 IOT POLY ENGINEERING 2-1 ASSIGNMENT 2 Example Follows LETTER THIS ASSIGNMENT Radio, T.V., Cell Phone, Internet, GPS, Remote Control For the 6 above technologies analyze the components (the goal, source, encoder, transmitter, receiver, decoder, storage, retrieval, and destination). You will need to research the devices in order to complete this assignment. Provide references.

23 IOT POLY ENGINEERING 2-2 Radio: Goal: Inform Persuade Entertain Control Manage Educate Source: Sounds and Information Encoder: Devices convert sound and info into modulated sine waves Transmitter: Antennas radiate the radio waves into air (medium) Receiver: Antennas capture the radio waves from air Decoder: Devices convert radio waves back into sounds and data [Storage: Recording devices store sounds and data for playback] [Retrieval: Stored data can be accessed and played] Destination: Consumers’ ears and eyes ASSIGNMENT 2 – Example
