This is a 10-week long project for the course, Human-Computer Interaction

We are currently at our finalizing stage and will have our 

This whole project is from the prompt 'Conversation'.

In this project, we used various UX techniques such as, 

  • Primary research

  • Secondary research 

  • Persona

  • Storyboards

  • Developing Concepts

  • Prototypes

  • User Testing/ Evaluation

My Role: Research Lead (research/persona/user testings), UI, Prototyping,




Part 1: Research

For our research, we started off with the question,

What is Conversation?

Conversation is: between two or more people, in which news and ideas are exchanged.

Ideas are exchanged the most when we collaborate.

And collaboration happens in group work/projects.


Survey responses 




Diary Studies

We had participants within the age demographic of 18-24.

Part 2: Insights and HMWs

“I’m scared to give my opinion because I’m scared to be judged.”

People are fearful of becoming the black sheep of the project.

“People are too transparent and don’t take other people’s feelings into consideration.”

If you don’t take the time to listen to other people you get associated as a ‘know-it-all’.

“Some people shut you down... they are kinda like bullies.”

There is an unspoken fight for power or competition of approval within a group.

Even if people were confident in their communication skills, 21% still preferred individual projects than group projects. This is because conversations require a lot of effort and soft skills. 

We learned that empathy, in particular, was the most difficult skill to have and achieve in group conversations.

How might we make empathy and active listening in group projects easier for increased productivity?

Part 3: Lo-fi and Mi-fi testings

Capturing voice tone to detect emotions

Utilizing AI technology to capture language cues

Analysis and visualization of data

 Core functions

We moved on to conduct user testing to identify any UX problems. We were able to recruit people that fit our target demographic. 

We observed their general reactions to the interface. As well as a quick questionnaire to fill in information about the User Interface design.

Here on the right are videos of the mid-fi prototyping we used for our user testings. 

Part 4: Prototyping and Final concept

So, we came up with...

Lighthouse is a collaboration device that visualizes both team members' tone and participation to encourage active listening and empathy within group members.

Through data visualization, the Lighthouse device and application help team members
better their communication skills.

We then continued to do further user testing with our Hi-Fi app prototype to get feedback on our UI
