RPS Hero
An interactive experience for a science museum.
Play Rock Paper Scissors on a computer with hand gesture recognition
Test your reflexes and hand-eye coordination in a Rock, Paper, Scissors game powered by LeapMotion!
Use real hand gestures to play, and challenge yourself across three unique game modes designed to push your speed and accuracy.

Aim / Target Group
This project was to create for the target group of 10 to 16-year-old teenagers with the aim of acknowledging them about "Quantified Self".
The project was exhibited in "Universeum"— a science museum in Göteborg.
What is Quantified Self?
...to share an interest in “self-knowledge through numbers.” ... tracking for any reason — to answer a health question, achieve a goal, explore an idea, or simply because you are curious.

7 Interviews with teenagers
2 Interviews with the museum staffs
📑 Learnings from academic paper:
"The dominant hand reacts faster."
"Reaction time varies from people."
"The reaction time can be improved by practicing."
Reaction time The difference in reaction time can be seen when comparing the dominant- and non-dominant hand, with a slight degradation in favor of the dominant hand [2], as well as a correlation between reaction time and intelligence [3]
Problem
How to design an interactive experience that acknowledges teenagers about Reaction Time and engages them in a fun way?
Interviews + Persona
Define.
☹️ Pain points
Experiences are generally not rich enough. The users soon get bored. Many installations only provide a "one-time" experience.
Interaction. Hard to get the whole family engaged during the experience.
Introduction. The users (especially older teens) don't like to be lectured.
🧐 How might we solve this
Spark users’ interest by making it easy for users to get started and offering a clear track of progress.
Make the experience simple but fun, using intuitive interactions.
Promote learning through playing by giving timely and meaningful feedback.
Develop.
Ideation I
Play Rock, paper, scissors with computer.
What do we make? → A Leap Motion (hand gesture) game
What do visitors do? → Use their hands and react to the randomly generated symbols
What do visitors learn? → Hand-eye coordination, reaction time, dominant hand
Leap Motion Controller
An optical hand tracking module that captures the movements of your hands with unparalleled accuracy.
Prototype
lo-fi
Design decisions
Display the players' hands on the screen. So they won't be too afraid to start.
The symbols come faster and faster
Have a leaderboard in the end.
But…
How to make it fun while keeping it simple? How to display the reaction time? How to give people things to think about once they've done with the game? How to let people fail gracefully?
Ideation II
New game mode
Inspiration:
the game “Rock Paper Scissors Lizard Spock"
Our rule:
"Rock→Scissor→Paper→Peace→Gun→Rock"
To make the game more fun and also employ knowledge-based recognition, we came up with a five symbol mode.
Test
16 Teenager participants
4 Test sessions + semi-structured interviews.



Why open up with our cool demos? Teens have less sufficient reading skills, also they are harder to concentrate. Simple language and fancy demos can help catch their attention and lead them quickly into the topic.
Why short sessions? To keep them concentrated and get feedback with high quality.
Why choose teens from the same class? To save time for them to familiarize each other.
💡 After 4 test sessions and the interviews, we adjusted the sound effect and some confusing screens. Most importantly, they think the "two hands mode" and "five symbol mode" are fun!
