Human Impacts on island ecosystems. (Australia) There are few paleovegetation records in Australia before 18‚000 years ago. To find out the history of the Australian fauna scientists used stable carbon isotopes from the emu eggshell (a flightless bird native to Australia). The samples were largely taken from Lake Eyre. The carbon composition of the eggshell tells us the composition of the bird’s diet (over 3-5 days). The emus are mixed feeders herbivores‚ eating leaves‚ shoots‚ fruits‚ flowers

HUMAN-COMPUTER INTERACTION – The Psychological aspects Human-Computer Interaction‚ abbreviated HCI‚ has simply been explained as the study of how people interact with computing technology (Olson & Olson 2003). It is the intersection between psychology and the social sciences‚ on the one hand‚ and computer science and technology‚ on the other. Throughout the past two decades HCI researchers have been analysing and designing specific user interface technologies‚ studying and improving the processes

What is Human Computer Interaction? Human–computer Interaction (HCI) involves the study‚ planning‚ and design of the interaction between people (users) and computers. It is often regarded as the intersection of computer science‚ behavioral sciences‚ design and several other fields of study. The term was popularized by Card‚ Moran‚ and Newell in their seminal 1983 book‚ "The Psychology of Human-Computer Interaction"‚ although the authors first used the term in 1980‚ and the first known use was in

HAM: Ham is a from a pig. Pigs live on a farm. Sadly‚ humans eat pigs for ham‚ pork and bacon. Bacon is good for the heart. Hearts are inside the human body. Without a heart‚ a human could not live. Without humans‚ our world would be over come with animals. Animals are important for the human world. Animals prove food‚ so humans can grow and become strong. Humans can exercise to strengthen their muscles. Muscles are very important for the human body. They are also very complex item in the body but

Prosthetics are devices that replace a body part that has failed to work or is no longer there. There are many areas of the body that can use prosthetics to help the body continue to try and do their correct functions. For example‚ people can have artificial legs‚ arms‚ hands‚ eyes‚ ears‚ noses‚ or thighs. Prosthetics have been around for a long time and have helped a large number people throughout the years. Even though prosthetics have been around for many centuries‚ there are still some improvements

Seminar questions 1. Discuss the challenges that are faced by HCI/professionals. Many examples are expected. 2. What kind of conflicts might designers face when designing computer systems? 3. Compare and contrast HCI‚ human factors‚ user interface‚ usability‚ user needs and user oriented design. 4. Describe how various disciplines contribute to HCI. 5. “Too many developers think that they are artistic geniuses – they do not bother to follow user interface design standards or invest the effort

Shneiderman ’s Principles of Human-Computer Interface Design: Recognize Diversity (kepelbagaian)- In order to recognize diversity‚ you‚ the designer‚ must take into account the type of user frequenting your system‚ ranging from novice user‚ knowledgeable but intermittent user and expert frequent user. Each type of user expects the screen layout to accommodate their desires‚ novices needing extensive help‚ experts wanting to get where they want to go as quickly as possible. Accommodating both
