Followings the evaluation plan for evaluating the redesigned userinterface.Observation: A constant observation is applied while the user is interacting with theredesigned user interface of the webpage of “Live Support”.Interviewing: The users are interviewed by selected questions as related with the userinterface after performed activities related with the webpage.Talking: A talk session between the user and evaluator is defined to gather the usersatisfaction level with new redesigned interface of the webpageQuestionnaire: A bundle of questions are prepared to be asked after the interaction of userswith the webpage which is being redesigned.Prediction: During the user interaction with the user interface of webpage to perform theassociated functional aspects the prediction of user activities and user performance andconfidence level are taken to determine the effectiveness and efficiency of the newredesigned webpage.Testing: The testing is lastly performed to rank the user interface after all the activities ofabove planned interface evaluation.
The user observation is close monitoring process by which the user interaction withthe interface components and user psychological, timing to perform the task,confidence level and the problems that are faced by the selected group of users areaccounted. This provides the basic details about the user satisfaction level andconsistency level with the user interface. Different level of users ay have differentlevel of the result of observation. These different results conform the user interfacefriendliness and usable with a certain level of users groups. The observation alsodefines the overall usability and ease of accessibility of the system such as webpageand its defined components with respect to the users of the system. Close observationprovides more accurate and detailed outcomes of the user interface evaluation of thegiven redesigned webpage.The participants are taken from three main domains of the user characteristics. Theseuser characteristics domain are novice user, average user and expert user. Thesedomain of the users provide the different evaluation outcome for the given redesigneduser interface of the system. The novice user provides the more detail about the allplanned activities information as this user has little or very less knowledge about theuser interface either of this redesigned webpage or for any other website webpage.The average user can do the tasks and observation. They would take less support anddoes the tasks. The average user has little bit expertise to surf the Internet so that thiscategory of user performs the interaction with the webpage as per the given task andsuse case activity scenario. The third category of user is expert user. This expert userhas too much expertise to surf the various website on Internet daily. This expert userdomain is just taken to evaluate the webpage user interface for consistency. Theobservation is required to observe the time and frequency of errors performed by thisexpert user in the evaluation process to find out the user interface usability withrespect to the general regular users who are much known with the such type ofmedical informatics field(Veal & Maj, 2010).The tasks are detailed in assignment 2. The same task is mentioned here pointwise toclearly specify the tasks as per the defined concrete use case.
