Reserve 25 (R25) WebViewer The R25 WebViewer is a web-based program widely used by college campuses, primarily used for event management & scheduling, allowing students to:
View course information, events and activitiesAccess the schedule of indoor and outdoor facilitiesReserve campus space for student organizations or personal useBusiness GoalsOur primary goal is to encourage students to become more involved with campus activities. Informed by usability testing and research, our event scheduling system can be modified for a more user-friendly and accessible experience. As a result, students will be encouraged to initiate and join campus organizations, fostering an active and cooperative campus environment.Two Locations:
Calendar of EventsWebViewer / Campus Calendar
A full-time undergraduate student who spends the majority of their time on campus.
A highly motivated and active student who initiates activities with their peers.
A student who belongs to an organization on campus or regularly attends athletic events.These are desired personality characteristics for participants in our studyParticipant ScreenerHow many credits are you currently enrolled? Which of the following age ranges are you in?Are you currently living on campus?Have you ever accessed our online Calendar of Events to view an activity or search course/activity information? Have you ever initiated or created an event on campus with the Center for Student Engagement?Do you currently belong to a student organization?Profile Summary of Five Users
Participant IntroductionThank you for taking the time to meet with us today. Were a graduate student group interested in better understanding how people interact with the R25 WebViewer Scheduling software and have asked for your help. So we can explore the software together, you will receive specific directions for each task scenario. You can withdraw from this study at any time, and will still receive the extra credit points from your instructor.If you have any questions, please feel free to ask the moderator. No personally identifying information is required and only the graduate student team will have direct access to your responses. You are encouraged to think aloud as you complete the scenarios, describing your thoughts and feelings to the extent you feel comfortable.The Missouri Western website is often busy and may take time to load new pages, so there may be some significant clicking-and-waiting. We thank you again for your time and patience.

Task #4 SummaryThe first two users began scrolled-down, where the top menu was not visible.Locating My Requests took considerably longer for users #1 and #2 (72 and 103 seconds).Once accessed, all users located New Request in 6 seconds or less.
Locate the ability to view only events held at the Griffon Indoor Sports Complex

Task #5 SummaryUser #4 took considerably longer to complete task 5 (283 seconds).After selecting Locations, user #4 did not scroll down to view Filter options until prompted by moderator.User #3 also selected Locations first, but recovered quickly by navigating the Filter options (16 seconds).
The ability to view = Filters?Task #11
Locate the option to display building locations only
Video 3/32:26Mean = 63.6 secondsVariance = 189 seconds
Task #11 SummaryAll users began task scrolled-down, where Locations was not immediately visible.Users #2 & #3 required a prompt to look away from the Filters optionUsers #1, #4, and #5 completed the task under 17 seconds. Possible learning effect at this point, where the Locations option had been previously explored.
The option to display = Locations?
XSUS System Usability Scale1. I think that I would like to use this website frequently. 2. I found this website unnecessarily complex. 3. I thought this website was easy to use.4. I think that I would need assistance to be able to use this website.5. I found the various functions in this website were well integrated. 6. I thought there was too much inconsistency in this website. 7. I would imagine that most people would learn to use this website very quickly. 8. I found this website very cumbersome/awkward to use. 9. I felt very confident using this website. 10. I needed to learn a lot of things before I could get going with this website. All questions are scaled 1-5 (1 = Strongly disagree, 5 = Strongly agree)Scoring the SUSFor odd items: subtract one from the user response.For even-numbered items: subtract the user responses from 5.This scales all values from 0 to 4 (with four being the most positive response).Add up the converted responses for each user and multiply that total by 2.5. This converts the range of possible values from 0 to 100.

Locations and My Requests
A persistent view of the menu bar while scrolling down the calendar of eventsAn example is given by Binghamton UniversityParticipants could not initially see the top menu bar when beginning tasks 5 and 11 (Global 2).
Having scrolled down, menu options remain visible above Areas to Improve Aesthetics Sorting through bolded information is strenuousThe color of the top navigation menu makes it easy to overlookViewing information as a grid(Global 3)
RecommendationsBold times instead of descriptionsChange the color of the text in the menu or the background of the menu so it is easily noticedNote about locations/additional featuresViewing information as a list is easier to use (have it be default setting)
