2.0 Literature Review

2.1 Benefits of E-Learning
Flexibility, Accessibility, Convenience
Learners can access the materials in their own time and study at their own pace and place [2]. With the Internet technology being widely used in homes and outdoors today, learners can easily access the learning materials even in the comfort of their own house or during outdoor activities. Since they can acquire the materials anytime and anywhere, they can easily plan to study whenever they feel comfortable without having to worry about the limited time they usually have in the school.

Cross Platform
Learners can access the content through window-based, Mac-based or UNIX-based computers [2]. As each individual has different preference towards their computer’s operating system, it is fairly helpful that the e-Learning is able to support all of them. With the e-Learning being supported in multiple platforms, learners can enjoy the contents without any interference or errors being shown when trying to access using different platforms.

Low Delivery Costs
Once e-content has been developed and uploaded on the server, it is relatively inexpensive to distribute domestically and worldwide [2]. As the contents are developed in electronic form and being stored in the server, any user can access the server and download the content. Since the Internet is available worldwide, users can get to download them anywhere and anytime. This can cut down the cost of delivering the contents by replacing the papers with electronic documents.

Ease of Update
It enables the content to be easily and regularly updated and instantly available to all learners [2]. Since the contents are in electronic form, it is very easy and simple to update and modify the contents without having to recreate the whole content like papers do. After saving the modified contents, it can then be uploaded to the server again for the learners to acquire.

Collaborative Learning
E-learning promotes collaborative learning thus resulting in more engaging and richer learning experiences [2]. E-learning combines different type of learning process that learners usually do not receive in the traditional method of learning. This could lead the learners to learn something in a new way which is engaging and at the same time enhance their learning experiences.

Scalability
Content can be delivered to a small or large number of learners with little effort [2]. Internet enables the content to reach or target the learners in a big or small group.

2.2 Human Computer Interaction and E-Learning
To create a successful E-Learning system, the human computer interaction (HCI) factor must be put into consideration. As mentioned earlier, HCI is the study of interaction between people (users) and computers. Human’s interaction with the computer should be highly interactive and easy to manipulate in order for the e-learning to be a fun and interesting tool to learn.
When examining the possible non-success of e-learning, one important factor worth exploring is the design of systems (or the adaptation) to support learning [3]. The interface design of the particular e-learning system is crucial in order to provide good and engaging learning processes for the learners.
HCI includes direct work on user interfaces that support learning. In addition, most user interfaces will be used in work settings where informal learning of work practices and work tasks are crucial. Thus, support for learning seems to be essential in much HCI work [3]. A good e-learning system would provide users with the functions they require to complete their tasks. It should be made to cater all the needs of the learners which the traditional mode of teaching could not provide.
