Augmented Reality

1.       Define augmented reality (AR).

Augmented reality (AR) is the technology of combining real word images, video, etc. with computer-generated information and/or imagery

2.       Provide some examples of how augmented reality might be used.

-Picking furniture

-Finding Places/ Find out out street names

-Interactive Prints

-Update on social network

-Happenings around you

3.       Traditionally a user would use text entry to search for  information in say Maps or  a search engine. How does AR offer a different alternative?
AR allows the user to use their actions to find the infomation. Pointing the AR at the direction will give you certain infomation about it. It uses a filter search so you can find specific infomation.

4.       How might the following people make use of AR;

●        A mechanic
"ARMAR, or Augmented Reality for Maintenance and Repair, is a head mounted display unit that provides graphic overlays to assist you in making repairs. An Android phone provides an interface to control the graphics you view during the process. Published in IEEE, and recently tested with the United States Marine Corps on an armored turret, ARMAR can cut maintenance times in half by guiding users to the damaged area and displaying 3D animations to demonstrate the appropriate tools and techniques."

●        An interior decorator
It can be used to demonstrate what a certain furnish would appear like in a room and what an ideas can look like when the room is completed.

●        A student

Flowchart Symbols

1. What is a flowchart?

A flowchart is a visual representation that illustrates the sequence of operations to be performed to get the solution of a problem.

2.Describe the basic flowchart symbols for;

Flow Line

3. With the decision making symbol (diamond) and the process symbol (rectangle), what are the rules for how many lines may enter and leave the symbol.

With the decision making symbol one arrow enters the box but multiple (normally two) can leave. With the process symbol one arrow enters and leaves the box.

4. Study the sample flowcharts then create a flowchart for a coin toss where heads means Mary pays for the pizza and Tales means Bill pays.

Example.

SUM is a variable
Essentially before 'N' it really says 'let N equal 0'.

 

What is an Algorithm

1.   boil the water,

2.   place coffee in the cup,

3.   place sugar in the cup,

4.   add the boiling water,

5.   add milk,

6.   stir.

1.           Examine the algorithm above. What two properties of the algorithm enable it to correctly describe the solution to the problem of making a cup of coffee? What is it that makes an algorithm correct?(Hint: what would happen if you swapped step "6" and step "2"?)

1.Specific
2.correct sequence

Swapping steps would change th end product and this case it wouldn't work at all.

Define Algorithms for the following processes.

Posting a letter. 1.Write Letter 2. Place letter in envelope 3. Write adress of desired place on the front of the envelope. 4. Seal Envelope 5. Stick Stamp on in top right corner 6. Place in post box.

Making toast. 1.Place bread in toaster 2.Push down lever to start toasting 3.Wait 2-3 minutes or until toast pops up 4.Place desired topping on toast

Calling a friend on the phone 1. Select friend to call 2.Press green call button 3.Wait for answer 4. If phone rings out try steps 1-3 again until friend answers 5.Talk to friend
