However, hope is at hand, through a recent study by a PhD Student at the University of Leicester, Kine Dorum,
Based on the notion that people create images or maps in their heads to represent the world around them, designers and developers often attempt to help people find their way by working on the principle that virtual environments should be made to look and feel as similar to the real world as possible. One example is the computer desktop with its files, folders, and 'trash can'.
Kine Dorum’s work suggests that how things look may not necessarily be an all-important factor when designing information spaces.
Comparing three identical-looking websites based on different real-world scenarios, the study shows that people tend to rely on prior knowledge of a space when moving around, rather than how realistic the spatial layout is.
Kine explained: “In other words, we don't need an image of a door presented on the screen in order to see a door in our mind, and a button on a website does not necessarily need to look like a real button.
“The effect of familiarity is so strong that it can have a greater impact than other factors that have previously been found to affect people's ability to use computer environments, such as individual thinking styles and a person's ability to orient themselves in space.”
So, while tapping into people's knowledge about the real world, these findings could indicate that there should be fewer constraints on the visual design of computer environments than are currently applied.
Through her work as a graphic and web designer Kine came to the field of cognitive psychology with experience of and interest in people’s differing ability to use computer based material. In her PhD project she is making use of psychological theory to test and gain insight into what happens at the interface between people and computers. The goal is to identify a set of key characteristics of both the user and the computer environment, which can be used to predict behaviour and performance, and inform design decisions.
The research is being presented to the public at the University of Leicester on Thursday 26th June. The Festival of Postgraduate Research introduces employers and the public to the next generation of innovators and cutting-edge researchers, and gives postgraduate researchers the opportunity to explain the real world implications of their research to a wide ranging audience.

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
