Case Study 2- One Hand Clapping

 

Introduction

One Hand Clapping is a 2D platformer that invites the player to sing to solve musical puzzles through their microphone and alter the world around them.All the player need is a microphone, headphones, and to play with their voice. Stand their ground against a hostile city's crowds; walk through the expansive, multicoloured biomes and sing to change the world; sing along on their musical journey with whimsical hermits.

This game is created by Bad Dream Games for people to explore the joy of singing. Singing is a magical thing that everyone can do but we don't normally sing unless we're in a bathroom or in a car where no one can hear. One Hand Clapping is a game that encourages players to make a difference inside the in-game environment by using their voice.

Interaction

One Hand Clapping lets the player discover the power that rests within their vocal cords while solving distinctive puzzles that require rhythm and a good ear. To resolve harmonic and pitch-focused challenges, the player must develop confidence in your singing voice and explore many different mechanics.

At the beginning, the game will calibrate to the voice of the player, so they are never required to sing notes outside of their vocal range. After calibrating, the player can control the hermit to move around by pressing on the keys. After learning the basics, the player need to use their voice to solve the puzzles they face, helping the hermit to across the landscape. Where there are places that the hermit can't just run up or over, the player can sing a platform that they can walk on to life. For instance, there are flowers that will only bloom if the player sing the correct note, opening up to provide a jumping platform, while bigger devices require the player to sing a certain phrase.

The background music the player accompanying is ambient and relaxed, and they follow the rhythm later when they are singing refrains back to a floating flower lady, so you know when it's their turn to sing.

How does it work?

To make the features work, the developer team used Unity's native mic class to record the player, then used an FFT algorithm to find the pitch as close to real-time as they could. When the player does the lowest comfortable note, it sets that pitch as the low end of your range, which is one octave. All the puzzles are based on the player's current pitch relative to that range.

IxD Project: Floor Projection Mapping Setup (Critics & Refinement)

Image
Floor Projection-Mapping Setup Critics & Feedbacks There was a critic session held to get feedbacks and critics from peers and lecturers. I will list down all the critics below. First of all, the animations take too much time. It does not have a rigid reason for the user to continue stepping within the circles because there are no animations playing and the feedback from the lines is too subtle. It was suggested to add some narrations to let users know what's the purpose of the graphics and animations. They should know what's the point standing and stepping around the circle. I should cut down the time and add some audio to improve the overall atmosphere.  Secondly, the feedback from the lines is too subtle. It's not inviting enough. Thus, I should tweak the formula and smooth time in order to get instant feedback when the user steps on it. For right now, I should minimize the smooth time to get very engaging feedback.  Thirdly, I was suggested to take out the looping o...

IxD Project: Production Process (Coding Design Development)

Image
Design Development This project is very challenging than usual because it uses visual coding which is very new to me. Before starting the visual on coding, I've tried to develop some visual to see how it looks like. I've tried to see and compare how does the circles will look like if added with dotted circles. Lines without Dotted Circles Lines with Dotted Circles Unfortunately, these designs look bad because I feel they look like Indian Diwali and it doesn't match with the overall look and feel that I want.  Design Development with Coding Formation of Circles with Joints At the very first stage, I've learned something very interesting which is creating circles using coding. This is very new to me as I never explore this kind of coding before. This feels like bringing back to my secondary life whereby the formula and calculations to create a perfect circle is being implemented now on coding. From this coding, I've understood that by instantiating the joints, it will...

Case Study 2 - MORI Building DIGITAL ART MUSEUM: teamLab Borderless

Image
      Introductio n       MORI Building DIGITAL ART MUSEUM: teamlab Bordeless is the world’s first digital museum that displays digital interactive arts. It is created by art collective, called teamLab and located in Tokyo’s Odaiba district. Teamlab Borderless is also known as a world of artworks without boundaries because it is a museum without a map.       The museum has 10,000 square meter spaces that uses 520 computers and 470 projectors. It is filled with more than 50 pieces of digital artworks. The 3D digital arts move freely and constantly in motion from one exhibition to the next so that the visitor can immerse themselves with the wonderful artworks together.   Interactions The artworks are spread across the museum’s five zones. The first zone is called ‘Borderless World’, an interactive digital landscape where visitors are encouraged to create their own path. People can walk through digitized waterfalls and touch luminescen...
