Mobile
phones have developed so much in such a small space of time once our brick like
phones to the current smart phones. The world’s first mobile phone
call was made on April 3, 1973, by Martin Cooper, a senior engineer at Motorola.
The phone that Martin cooper used weighed 1.1kg and measured
“228.6x127x44.4mm”. This mobile phone allowed you to talk for 30 minutes,
however took about ten hours to charge its battery. Short messaging service was first used on the
3rd of December 1992 by Neil Papworth “via Vodafone network to the
phone of Richard Jarvis”.
Many of the modern day smart phones use a processor called an
ARM. These ARM’s are used as they reduce cost, heat and power use of the phone
it’s self. These ARM processors “require fewer transistors than typical
processors” that are used in average computers. These processors are also used
in smart phones due to their “desirable trait” that allows them to be used in
devices that are battery powered.
The first camera phone was first sold in 2000 in Japan more
than a decade after the first digital camera was sold. This camera phone used
CCD sensors compare to today’s likely choice, the CMOS active pixel senor. In
addition to phones now being able to take photograph images, we are now able to
take high quality videos with our smart phones due to video capabilities.
Similar
Characterises as a Computer and Laptop
Many of today’s smart phones are extremely similar to
computers and laptops for their characteristics. Such characteristics as being
able to have access to internet, check your emails and keep up to date with
current news on the go. You are also able to watch films and videos at the
touch of a button. In addition to this you can have 64GB worth of memory on
your smart phone, to store endless amount of application that allow you to do a
range of different things for example shop online and control your
banking. The amount of memory that you
can have on such a small device shows how much a smart phone is very similar to
a computer these days.
Megapixels
in smart phones
A megapixel is one million pixels. A pixel is a “physically
point in a raster image”. These pixels will store information of its
coordinates within an image as well as its colour. When many of these pixels
come to together we create a line or shape which them becomes our picture.
Smartphone’s use pixels or should we say megapixels to display all of the
information that we see on screen. This includes the background image, the
image that is created to represent our application, our clock and even the
movement of objects on our screen. However the phone companies are always
trying to give us more megapixels in new smart phones that are brought out, but
are we really getting any more, megapixels in our phones, although it may seem
at first that we are? The HTC One has 4 megapixel camera compare to the Apple
iPhone 5 having 8 Megapixels however although you would believe that this would
mean that the picture you are getting twice the size picture. However in
thinking this you are wrong because the megapixels of a camera is based on a
figure times another figure therefore from the image below you can see that the
size only slightly increases in size compare to what we would have first
believed. Therefore it never is which smart phone has the most megapixels it is
which smart phone produces the better quality.
The Rise of
Digital Cameras
The rise of the digital camera happened in 1969. The first
digital camera was invented by Willard S. Boyle and George E. Smith who
successfully created an imaging technology using a digital sensor. Willard S.
Boyle and George E. Smith were awarded the Nobel Prize for Physics in 2009 due
to this contribution to digital photography. After this in 1975 Kodak engineer
“Steve Sasson” invented the first digital still camera. This first digital
camera used a “Fairchild 100x100 pixel CCD”. Finally on August 25th
1981, Sony “unveiled a prototype of the Sony Mavica”. This camera was the first
analog electronic camera which “featured interchangeable lenses and a SLR
viewfinder”.
Are we
developing technology too fast?
Yes I believe that we are developing technology too fast as
we currently live in a world where there are already many people who rely on
technology to communicate with the people around them compare to the years of
my grandparents where if you want to communicate with someone you wrote them a
letter or went and asked them in person.
Examples of where developing technology can be a problem is
where we reach a stage were the whole world has forgotten and doesn’t use the
ability to communication through spoken language. People will only communicate
via their phones texting and their emails. This can have an extreme detrimental
effect on the people of the futures ability to speak to each other as they will
be living in a world where no one speaks to each other.
Smart
Internet Enabled TV’s vs Cathode Ray Tube TV’s
Cathode Ray Tube televisions display your TV screen image by
three electronic guns shooting electrons through a tube at the front of the
screen. This beam would then place “thousands of dots on the screen” to form a
picture. Compare to current smart TV’s which like the Plasma televisions which
were made up of two sheets of glass which between them held millions of coated
pixels which were “coloured phosphor, red, green and blue”. When electricity
would pass through these sheets of glass it would cause the “coloured phosphor
to produce light”. TV’s now allow people to access the internet using Internet
smart TV’s. This involves you being able to control your television using your
voice and the motion of your body. It allows you to access a “world of online
content and services”. In addition to this these smart TV’s allow you to have
3D viewing.
3d
Modelling Printers
HP DesignJet 3D Colour makerbot printer is a printer that
allows you to print and create 3D objects. Compare to common 2D printer which
just print a layout of dots in the correct order, a 3D printer will print small
blobs of plastic or other material in the same way as a 2D printer however when
the process has completed over to whole area being printed the base of where
the small blobs of plastic are, gets lowered. This then allows the 3D printer
to continue with the same process placing more of these small plastic blobs on
the already set plastic blobs making it into a 3D object. This continues until
you have the density or size of the object you wanted. Therefore this means
with the right computer software you can create anything you want in 3D, even
with moving parts.
These printers now allow us to print rich and complex graphics
in 3D form for us to hold and use. Look at this video below to see a common day
tool made in a similar way to this, however this company uses a powered instead
of plastic to create the object using a 3D printer.
Projectors
starting to challenge larger screen cinema systems
Projectors are starting to challenge larger screen cinemas
systems because they allow a person to have a home cinema system in their own
living room at a small cost compare to going to the cinema. Projectors on the
market offer much better picture quality with up to 300 inch screen
possibility.
Good detailed information, I think it needs more pictures to show the audience what the information is all about.
ReplyDeleteI will take your comment on board, as I do believe that I will need more images on my blog so that the audience doesn't get board of reading pages of text. It also would be a good way of showing them what the phones looked like back then and how much they have changed, for example their size has change dramatically as when as the shape of the modern day phones.
DeleteYour blog is very detailed, but you should try to add some colour to your blog to make it look more good to the eye
ReplyDeleteOk I will take this on board as I do think that it may be boring to the people reading if it is all the same colour.
DeleteYour blog has a lot of good, detailed information which is easy to understand. I think you should add some more pictures to bring in colour and to show the audience what the changes are to give them a better idea of it.
ReplyDeleteOk, adding colour would make my blog more interesting.
DeleteHere is the updated blog with the changes that you spoke about.
