Fundamental Principles of HCI Design
Fundamental Principles of HCI Design
Introduction
I will be describing the principles of HCI and Interface Design, giving examples of each of them in use. I will also be talking about perception (including colour, luminance, Pattern, Pop Out Effect and Gestalt Laws), behaviour models (including Predictive Modelling, KLM, throughput and Fitts Law, descriptive modelling (including KAM, Buxton’s model and Guiard’s model) and Schneiderman’s 8 Golden Rules.
Schneiderman’s 8 Golden Rules
Eight rules have been created by a person called Ben Schneiderman which was in a document called “Designing the human interface”. These 8 rules derive from a collection of principles and personal experiences that have been collected, refined, extended and improved upon till 8 rules were finalised.
Perception
Perception will be different for both the developers and the users. Users won’t understand the smaller details in the graphical user interface and the importance of the location of aspects and the colours used in the graphical user interface on the desktop and how these could affect the use of the programs. So everyone involved in the project including designs and programmers must entirely understand the wants of the client and ensure they have the same perception.
Colour
Colours are very important and designs must take this into considering when creating the graphical user interface, big companies like Microsoft invest money into finding out about colours and the effect it has on people and they found that the colour grey is a dull colour and doesn’t attract much attention so they use this as the main colour in their products (often background colours) and then for drop down menus they use colours like blue which stand out but aren’t irritating to look at and read off, if you compared the grey colour and instead used red as the background colour for menus and panels it would be very annoying to look at. Also medical conditions must be taken into consideration for
