1 Introduction:
Interface Analysis in important because it is a process that assess the relationship between the man or the users and the machine interface (Stanton 2005, p. 431). It caters the different physical characteristics of the interface that can affect the performance of the human that is using the system. The result that can be drawn from any interface analysis can help to improve the current interface problems of flaws in redesigning process. The use of different method can help to enhance and improve the presentation of the design, features and utilities by developing all of the system’s usability, the satisfactions of the users as well as preventing different errors and enhancing interaction time Stanton 2005 p. 431).
ISO09241-11 requires the usability of the system by considering three different dimensions: first is the effectiveness of how well the performance of the system meets the task or the activities that it was designed and created for; second is the efficiency of the system in dealing with the different important resources like time, money and effort that are necessary for the users to manipulate the system; and the third and the last is the reaction of the users towards the system (Stanton 2005, p. 432).
Stanton (2005) stated that there are many methods that can be used in implementing the interface analysis: the usability assessment, error analysis, interface layout analysis and general interface assessment methods (p.432).
2 Usability Assessment
Usability Assessment is an approach that is used in ensuring the usefulness of a particular system. It had been used during the 1980s due to the desired output of the development of the user interface of the system. Later on, during 1985, the approach has reached its popularity due to the works of Gould and Lewis that described the four primary needs of a system in order to obtain the usability of the system. The said four criteria are: early and constant focus towards the users; incorporation of the different deliberation of all of the aspects of usability; trying the untimely and uninterrupted version of the product to the user; and the last is redesigning (Nemeth 2004, p. 265).
The main purpose of the said assessment is to find out if there are some difficulties about the usefulness of the system in the perspective of the user that can help to uncover the different opportunities in enhancement and transformation (Nemeth 2004, p. 266).
3.1 The William Ponder (MIS) Way-Finding System
The way-finding system of William Finder building is to be installed in the ground floor of the building that consist of a computer set that is connected to the web. The said system will help the first time visitors, visiting academics for meetings, students from other schools who are attempting to locate different tutorial rooms and the friends and relatives of students who will submit coursework.
3. 2 Self-conducted User Test
The method that has been used in analyzing and testing the usability of the system is based on the experience of the author in the interaction to the system. By using the perspective of the user, it will be easy to define and analyze the reaction or their response to the system. There are some flaws that have been found out during the personal test of the system. Most of it focuses on the design and the user-friendliness of the system.
3.2 Task Analysis – Different users has their different requirements, needs or demands for a given system or interface. That is why conducting a usability test can help to cater to the said demands of the end users. Here are the task analyses of the William Ponder (MIS) Way-Finding System:
On the other hand, other users are requesting for a search features where in it will return the information about the specific staff that they are looking for. This is to prepare the system for future enhancement, for example, the number of staffs grows to 50 or so, it will be hard for the user to search for the desired staff. Another thing is the feature of the system where in, it uses the initial of the first name together with the last name can confuse the user in the future. What if someone with the same initial of the first name and last name was hired by the company, it will hard to distinguish the difference between the two if you are not familiar with them and their position in the company.
3. The Prototype
Figure 1 Welcome/Menu Screen
Figure 1 shows the welcome/menu screen of the interface where in the user can choose between the two commands which are the search for the staff and search for a room. By doing this, those users who are going to search for the information about a specific room only doesn’t have to go through the process like those who are looking for some staff.
Figure 2 Search for Staff Form
Figure 2 shows the prototype for the search for stuff form. As shown in the figure, the search button is placed on the upper part of the form. By doing this, those users who knew already the name and position of their desired staff will no longer have to search for their room information in manual form. Also, as the form load, the names and positions of all staffs will be display in the list and the user will have to double click the data and they will get the information. The floor map button will be linked to the form that displays the map of specific floor where in the requested room located. The status will display if the staff is available or not, this will serve as added information in case they need to talk to the staff personally. The user can leave his or her message to inform the staff about their visit.
Figure 3 Search for Room Form
Figure 3 shows the prototype of the form that shows the information about a particular room. As the form loaded, the list of all the rooms as well as its type will be displayed, but again in order to make the life of the user easier, the search feature will be included. The room type will signify if the room is a teaching room or the other types. The button floor map will show the form that will display the floor map of the desire room.
Figure 4 Floor Map Form
Figure 4 shows the form that will display the floor map of a given or requested room. As you can see the requested room is displayed using other color, by doing this, it will caught the attention of the user and will no longer have to spent some time searching for the room.
