Interactive Art Installation Connecting the Physical and Digital Spaces with Sound
digiPop is an interactive game art that seamlessly connects the physical and digital spaces. The concept is to blow virtual bubbles into the digital canvas and is inspired by Mark Weiser's vision of a new paradigm for human-computer interaction  where technologies "weave themselves into the fabric of everyday life until they are indistinguishable from it". The bubbles straddle the physical and digital worlds with sound as the mediator between the two spaces.
The gameplay follows the way children play with bubbles. Through a built-in microphone, people can blow differently shaped virtual bubbles into the digital canvas based on the frequency of their voice while also interacting with them through body gestures captured by a camera. The velocity and shape of the bubbles as well as the rate at which they are created depend on the volume (i.e. pressure) and the peak sound frequency at which they are blown. For example, blowing into the microphone creates high pressure, allowing players to create many bubbles quickly. By whistling and singing at different sound frequencies, they can affect the velocities of digital bubbles blown towards one side of the screen. Fast moving bubbles are generated with high frequency sounds while slower bubbles are created with lower frequencies. Once the bubbles are in the virtual space, players can interact with them through gestures. They can combine them into bigger bubbles, pop other players' bubbles, maneuver bubbles around obstacles, all by using any kinesthetic interactions imaginable. Although existing in virtual space, these bubbles loosely follow the laws of conservation of mass and momentum to signify their connection to the physical world. Digital computation is used to allow for augmented interaction that cannot be otherwise accomplished in our physical space.
Each digiPop bubble remembers the frequency used to create it that is then played back as it moves across the screen. A high A note (440 Hz) is played when bubbles collide into each other while a pop sound plays when a bubble bursts. These sounds create a feedback loop into the bubble formation, accompanying the player's voice for a unique concerto.

Human Computer Interaction Research
Following the notion of ubiquitous computing, the setup only requires a webcam and a microphone, which are available on most computers, so that anyone can play the game anytime, anywhere. The intent of the project was to make a fun and accessible computer-based game for people of all ages. The goal was to move away from mouse-based interaction and take inputs analogous to natural actions children make when playing with bubbles. The low-res display encourages people of all ages to become more playful and expressive with their movements. Not only is the intuitive interface essential for human-computer interaction but it also invites interaction between friends and strangers alike.
