FORMATIVE EVALUATION
We conducted a formative evaluation study with 3 users - all students. We used Wizard of Oz prototypes, a technique in which users interact with a system which is operated by a wizard, thinking the system is actually processing the user responses. Before the beginning of each task, the facilitator explains the task. Once the user is clear with what he/she must do, he/she is presented with the paper models of the interface by the Wizard. A sheet with all the tasks and their short descriptions is provided to the evaluator. Evaluators can refer to it in case they’re unable to remember any of the told details.
Some aggregated conclusions from the observations of formative evaluations are as below:
Providing help/suggestion texts on hover is needed to identify the purpose of some functions such as a “Meeting ID” or “Later” button on start meeting page.
Not to ask for a schedule if the user wants the meeting to start now.
The design/flow to finish current topic needs refining.
Once user confirms addition of a newly detected topic from human conversation, it needs to be set as the current topic as the topic is actually under discussion. It did not reflect in the Wizard of Oz prototype.
All evaluators complemented the UI to be simple and intuitive.
SUMMATIVE EVALUATION
We asked users to perform three tasks on Xpresso. It was a limited study under controlled environment. We measured time taken by the user to complete the task, success on task and the errors that occurred during the execution of the task.
Task 1: Login into the system & Set Agenda including Date, Time, Topics to be discussed, etc.
Time: 47sec
User was comfortably able to do the task
Task 2: Join existing meeting using the meeting ID created earlier and shared with everyone
Time: 19sec
User was able to relate the flow with other commonly used meeting applications and could easily follow the task
Task 3: Explore the search screens and move the topic from undiscussed topics to discussed topics.
Time: 33sec
Error: 1
The user was not able to identify how to move the topic to Discussed Topics initially. But finally, was able to find the correct steps.
