Perceptual Data

I just can't get my head round it, can anyone help (if we're allowed to do this, its not part of an assingment)
I'm having problems trying to explain in my own words what it means. The internet is of no help.
If any one can give me clues I would be very grateful.

aaaah Joni i hear you there brother, i'd like to help but you are ahead of me, i thinks, i'm busy doing all the exercises from book 1 grrr poinless maybe but its settling my worries of leaving incomplete exercises and activities

but if you remember to practice your Harvard guide to citing references Ha! i maybe we'll be able to find were you are stuck and get to grips with your problem and if i cant help and get stuck together at least we will be singing from the same hymn sheet so to speak you are not alone my friend i share your frustration

Hi Dean
Thanks for replying, its sister actually
I'm still on unit 1 but I am doing a bit of personal revsion just to make sure I understand all the learing outcomes. They are at the back of the book.
I sometimes find it difficult to explain things. I found when I had worked through the excercises I was still a bit unsure of what I had learned and I wasn't sure what I was supposed to be getting from the web refs.
Do you find the excercises off puting with the answers underneath?
We'll get there in the end!!

whooops sorry sister

i too am on unit one but read through the whole book and made a start on all the exercises and activities i have just started the first activity 4.1 ??? i can see their point, and it does say that it starts at the bottom of the skill level, but i am struggling to keep my concentration on such basic tasks like how to surf the net.

i totally agree with you about the layout of the thought prevoking questions with the answers writen straight underneath. its almost impossible not to read them, you trick your self to have a quick peep to confirm that you are on the right track then you end up reading the whole blooming answer (well i do anyway lol)

oh and you were explaining your self well i was just pulling your leg as i had spend over an hour getting to grips with the whole referencing thing-am-me-jig and reading your post switched the light on for me in regards to why it is important from the readers point of view to know what the author is refering to (thanks for that..nice one)

oh and as for your question about on M150 Data, computing and information (2008)Page 47 exercise 5.3 regarding perceptual data

sorry i aint got a clue LOL i've read through it several times and it just gets more confusing, but as this is unit one we are proberbly over complicating the question and the result is just an observation to be considered rather than a comlpex data extraction

but this is just my train of thought and as allways i maybe wrong i suppose this a question for the tutor...

hope i haven't confused you more..

hope this helps

To be honest perceptual obviously means than what you see (to percieve), now if I take 2 photographs from my window each at the same positions as my eyes and with a fairly good camera, then someone else can see what I am seeing fairly easily. The matter is, whether you are storing all the data from outside or just the visual data.

So even though the book says that dna is fairly simple with only 4 basecodes, a photograph can be easily translated to binary which is merely 2 basecodes. If you wish to campare complexity with DNA it depends entirely on what range of information you want, but for the large part DNA will remain far more complicated having billions and billions of coding just to make up one strand, DNA has almost infinite capabilities.

That said the above example is assuming you are taking the view only once at a certain range, remember the human eye while very complex is made up only of a few million receptors to see with (about 150 million in black and white and 6 million in colour) so we see things almost in pixels anyway, real life objects are not made of pixels but atoms and molecules, if you wanted to store this code in base form you would need enough enough DNA to fill the universe I bet.

As you can see the question they ask is not really a very good one, they should have better describe the range of perception and what information should be in the percieved image.

Thanks Guys thats really helpful!
