Size matters

The screen size of my application will be important on how it will display the items i want it to display.

My Application Will be designed for the screen resolution of 160x 128 this is the largest size for mobiles phones, My application is aimed at only mobiles phones and not smart phones because smart phones are already capable of supporting route finders and things similar to this. and also the fact that there are more people with mobiles phones than smart phones.

On the screen i need to think about the following factors

• Text
• Positioning
• colour
  

Text

First i will talk about text. text is very important especially on small screens devises. one thing that is very important is " the smaller the type, the greater the selected contrast values should be. the brightness-contrast value should not fall below 50% for black and white text"(Designing for small screens, studio 7.5)

It is important also not to use Serif fonts for small screens as its allot harder to read the text, so for my application i will be using San serif fonts and only using 1 type of sanserif font so the users are familiar with the text and don't get confused with all different types.

It is important to make the text stand out with a non clashing background for example if you had pink writing with a light green background these two colours will clash especially on a small screen so it would be more sensible to use colours that compliment each other like black and white.

Positioning

When it comes the the positioning of the items in my application i want to keep everything very simple so the user doesn't get distracted. i want it to get right to the point so it will take you less than 5 minutes to find what you are looking for.

I will be using the law of symmetry so everything is equal and wont mess with the human tendency of perception everything will be balanced and harmonious. but in some cases this rule can be broken for the attention of an icon to be focused on more than the rest for example if you are in a selection menu the selected icon my be off centered so you know you have highlighted that icon. All my text, graphic boxes and windows will be centered so that the balance is equal.

Colour

I will keep the colour of my application very simple as its not the main aspect of my application
i will use colours such as black, white and grey and make sure i avoid colours such as red and blue so for the users who are colour blind can see what the text says.

The text will always be either black with a white background or white with a black background because they compliment each other and don't clash! this is a major aspect as i know how annoying it is when two colour clash.


The Price is right!

For the final part of this post I'm going to talk about price and to take into consideration of other products and how much they are.
I went to http://www.youpark.com/ and had a look at the prices of each applications and they seamed to vary allot. i had a look at this particular application which is a GPS navigation for the modern mobile phones and noticed the price which was 13.22 pounds. this gave a basis on the highest price i could sell it for. My application doesn't have as extensive features as that application but i though it would be appropriate to sell my application for 4.99 i chose this price as this is the average amount most applications/ games sell for on on the Internet so i thought it would be sensible to keep it the same otherwise people wouldn't buy it.

Thats it for this post
