Today, if people search “karaoke” in the App Store on mobile, they will get quite a number of apps in the search results. However,
none of them can provide a live karaoke experience. In existing karaoke app services, singers record songs through the applications
and upload their performances to the online community. The audience would listen to the performances and post comments later.
LiveKara is a mobile application designed to provide a live karaoke experience. It involves both singers and audience in the
performance simultaneously. People may send live comments as user-generated content that can be viewed by the entire audience and the singer.
LiveKara was my Master's project for my MS degree in Human Computer Interaction at Georgia Tech. For this individual project, my
duties covered the end-to-end design process, from user research to ideation, creating UX flows and UI sketches, building rapid prototypes,
conducting usability testing, and showcasing my work on the final presentation day.
How I Design
An online survey was distributed to learn people’s opinions and experiences with karaoke places. 139 responses were
received with the age ranging from 21 to 40, and the gender 64% male. To ensure the validity of the results, 25 responses were discarded
since they had never been to any karaoke places.
Among the remain 114 responses, 50 of them had only been to western-style karaoke bars, 50 of them had only been to eastern-style karaoke boxes,
and 14 of them had been to both. These numbers established a
balanced view of karaoke bars and karaoke boxes in this survey.
Of 72% of the responses who gave a performance at a karaoke place, 53% indicated they would like to get the audience's
attention when they were performing on stage, while only 12% didn't want to be paid attention.
Among 91% who had been in the audience, 49% of them chatted about the song with their friends, and 31% sang along. This
result indicates that people are highly involved in the performance and they have a strong desire to share thoughts while watching.
Although the responses indicated a balanced experience between karaoke bars and karaoke boxes, 61% preferred the karaoke box because they feel
more comfortable singing with friends in a private space. To many people, the social aspect is one of the top motivations for doing karaoke, but
many felt some stress or anxiety when singing in front of others.
To enhance the karaoke experience and encourage social engagement, LiveKara is designed to be a karaoke lover's social community. In LiveKara,
everyone has a skill level: "novice", "intermediate", "advanced", "rising star", "superstar" - based on engagement with the LiveKara community.
For the singers, I designed two performing modes - "solo" and "duel".
Solo: only one singer perform at a time
Duel: two people sing one song and compete with each other
If a singer selects a song for "duel", LiveKara searches for other online singers at the same skill level who are also looking for a match for
the same song. In each performing mode, before the show starts, there is a 1-minute preparation period for the audience to join the performance.

For the audience, people may join the performance through the live show list, which is lists of songs that are in progress or still in the 1-minute
preparation period. To make the audience more engaged with the show, two highlighted features were designed for them:
Vote: during a performance, the audience may heart the singers. Singers will lose the hearts as punishment if they quit before the end of the song
or before all of the audience leaves.
Comment: as the performance continues, live comments can be shared in a form of running text on the screen. If there are too many running comments
that make people feel distracted, they can always mute the comments and focus on the show.

Adobe Edge Animate was selected as the prototyping tool for this project because Edge Animate can create interactive content and generate
lyrics and live comments in LiveKara. Beyond that, I was also able to customize the generated code to make the prototype reflect all the details
in my design.
Prototype - select a song and match a singer
Prototype - set up and invite the audience
Prototype - during the Duel
Prototype - choose a song to listen
Ten participants were recruited for the design evaluation. People were asked to be singers and give a duel performance and then be the audience
and listen to a performance. As the audience, they were asked to vote for the singers, post comments, and mute live comments. During the study,
a few questions about screen flow and user interface were asked to find out how people interpret the design. At the end of the study, a
questionnaire was filled out by each participant.
Overall, participants performed very well in the study and showed a good quality of interpretations. 8/10 participants completed all
tasks effortlessly while 2/10 participants had difficulties when they were looking for the route to listen to a performance. 3/10 participants
could not understand the meaning of the headphone icon located in the top right corner, which was meant to indicate the listeners/audience in the
current live show.
Tasks for the Participants
When participants were asked to be the singers, a few people questioned if they would be able to do it privately. They wanted only the audience
members they knew to join their performance. In the current design, there are two ways to recruit the audience: a singer may send invitations to
someone in LiveKara that the singer would like to invite, or any audience may join freely through the live show list.
In future designs, a checkbox "open to the public" will be added when people set up a performance. If they uncheck "open to the public,
the performance will not appear in the live show lists and strangers will not be able to join. Beyond that, if people are open to 2nd-degree
connections (friends of friends), they may check "allow people to invite" so their invitations can be extended to more people but still stay within their
