Changing how one can experience their world.

EzTour application allows users to be able to create a tour that leverages augmented reality.



We want this tour creator to be able to host a tour for other users to attend without being limited by the current COVID-19 situation around the globe, hoping that this would be a versatile application applicable across domains: from the tourism sector to any organization that may want to arrange a tour, such as student groups during freshmen orientation.


Add any number of hotspots to a tour, add any number of waypoints to a hotspot. Let your participants be fully guided by themselves.

The Problem

With COVID-19 cases first started rising back in 2020, many people minimized interactions with one another to reduce the spread. This causes a decrease in revenue.

We began the project with market research, in order to establish the potential users. We focused on finding out how our potential users would use our application.

Who Conduct Tour

  • People who are constantly having the need to introduce their environments to visitors
  • Tours common in Singapore: school tours, museum tours, for overseas tourists

  • How People are Conducting Tours
  • They generally arrange a few hotspots to visit
  • At each hotspot, they have explanations/activities for their visitors

    We conducted user interviews with people who have organized tours for school-related events. We looked for people who were either lecturers or student leaders. Our goal was to learn more about their processes of arranging and carrying out tours in school. The interviews were conducted face-to-face.

  • Number of Participants: 2
  • Gender Breakdown: 1 male, 1 female
  • Age: 23 - 54
  • All participants have active leadership in their schools

    For this application, the target user classes were students and teachers, specifically those involved in event planning, with the motivation of introducing the campus to new students during events such as orientations.

    While the application proposed was versatile and might have more wide-ranging use cases, we decided to focus on campus tours for this 1st version of the application so that the application would be more focused and cater better to most, if not all of this group’s needs.

    We identified two main user classes:

  • Working professionals, such as instructors, lecturers, and non-teaching staff in the Student Life department
  • Students, such as student leaders in a student body/organization


    I created a persona so I could have a better understanding of the target audience. Thomas Lim emerged from the primary research findings, with his goals and frustrations drawn from the trends in user interviews. We referred to him throughout the entire product development process.


    I mapped out Thomas' steps to see how I could simplify the users' journey to help them reach their most important goals with the product.
    Mapping Thomas' user journey revealed how helpful it would be for users to have access to a dedicated tour creation app, especially in the midst of the COVID-19 situation.



    By having a domain analysis, we were able to identify important things in the domain, such as:

  • People, the user classes
  • Physical object
  • Information object

  • This allowed us to determine the important relationships between the identified things. From the domain analysis, we could identify new potential users and tasks that were missing.


    By having a hierarchical task analysis (HTA), we were able to identify users' primary goals, the steps the users should perform to accomplish their goals. We broke down each task into multiple subtasks, expressing the relationships between the parent task and its subtasks through a numbering scheme. Though the HTA did not communicate anything about what was happening at the level of a user's interaction with the system, it gave a clear understanding of the task's high-level steps.



    The first step of the design phase was the drawing of the low-fidelity wireframes. The low-fidelity wireframes helped me to focus on the layouts and visual hierarchy. The paper wireframes were useful for testing purposes.


    The sketches were then followed up with digital wireframes, in which the sketches took on a digital form and were prepared for usability testing. The wireframes did not have many details so I was able to focus on the functionality of the features instead of the visual design of the app.
    As the initial design phase continued, I made sure to base screen designs on feedback and findings from the user research conducted while testing the paper prototype.



    Before launching the product, I did a testing round in order to reveal possible usability problems. The users were given 4 tasks to carry out using the digital wireframes. Participants were lecturers or students from Singapore Polytechnic or DigiPen@SIT.


  • Create a tour
  • Add briefing to the tour
  • Create as many hotspots as you desired for the tour
  • Plan the route by connecting the POIs

  • Here are some pain points users faced:
  • Many felt that 'Recently Opened' and 'Tours' sections were not really necessary, as they were almost similar
  • The 'Updates' section did not help
  • Many felt that they did not know if their tours were published after they completed them
  • There was no way to add Points of Interest (POI) in each hotspot

  • Recommendations
  • Add a search function to allow users to look for the tours they want
  • A toggle button will allow users to choose if their yours are in draft state or published state
  • The Hotspot page allows users to add multiple POIs


    Once I tested out all usability mistakes, I started designing the final screens in Figma. The UI kit was applied to the digital wireframes to create the high-fidelity wireframes.

    As the initial design phase continued, I made sure to base screen designs on feedback and findings from the user research conducted while testing the paper prototype.

    While designing EzTour, it was definitely an enriching experience as it was my first time working on the UI/UX aspect of an application. Working in a group in which everyone was unfamiliar with UI/UX was very interesting as we had the chance to learn everything together from the basics. With 5 of us in the team, many different ideas were suggested, some of which were rather interesting which would not have been possible if this was a solo project instead.


  • Interviewing our lecturers and schoolmates helped us understand what was needed, and there were issues that we did not think about
  • When the final product came to live (link is below, credits to my groupmate Joey), we were very proud of what we had done
