Efficiency
Many technological product, neuclear reactor, control system, require the HCI to fuifill their technical complexity to a usable product. Technology alone may not win user acceptance and subsequent marketability. The User Experience, or how the user experiences the end product, is the key to acceptance.
For a given HCI, company and users usually more concern about the following questions:
1) How easy for new user to lean to operate the interface?
2) How much time and effort it takes an operator to finish a given mission without any supervision?
3) And more important, what is the improvement on the productivity by using the HCI?
If the user feels the HCI too hard to learn, or not easy to use, software will not to be accepted by the users no matter how well it is. Good User Interface Design can make a product easy to understand and use, which results in greater user acceptance.
In HCI, efficiency is measured as the resources expended by the user in relation to the accuracy and completeness of goals achieved. High efficiency is achieved when the user finish the mission with few resources in terms of time cost, leaning cost as well as maintain cost, etc.
There are several criteria that will be used to measure the efficiency of the Human computer interface. The criteria include the design, usability and performance of the HCI. The Data Envelopment Analysis (DEA) technique can be used to meansure the HCI efficiency.
