Project Description: 

ABSTRACT (2018) is an interactive digital painting collective that tracks and collects simple ordinary strokes from users’ mobile devices and in real-time, translates them into lively vibrant strokes projected on a wall. The installation was projected onto the wall of the Experimental Media room at OCADU November 23rd, 2018.  ABSTRACT’s public canvas is also accessible online so participants and viewers alike could engage and be immersed in the wonders of ABSTRACT anytime, anywhere.

The idea of ABSTRACT was to express and celebrate the importance of user presence and engagement in a public space from a private or enclosed medium such as mobile devices. Since people tend to be encased in their digital world through their phones or closing themselves off in their own bubbles at times, it was important to acknowledge how significant their presence was outside of that space and what users have to offer to the world simply by existing. The users make ABSTRACT exist.

Here’s the latest documented video of ABSTRACT below:

Nov 15th, 2018: Brainstorming  Process

(Figures 4-6. Initial stages of brainstorming on Nov 15th.)

Ever since experiment 1, I’ve always wanted to do something involving strokes. I was also interested in creating a digital fingerprint that could be left behind by anyone that interacted with my piece. I kept envisioning something abstract yet anonymous for a user’s input online. Trying out different ways of how I could picture what I wanted to do, I started thinking about translating strokes into different ones as an output at first just between canvases on my laptop.  I wanted to even go further by outputting more complex brush strokes from simple ordinary ones I drew on my phone. A simple stroke could output a squiggly one in return or a drawing of a straight line could appear diagonally on screen. I kept playing with this idea until I decided to just manipulate the colour of the strokes’ output for the time being.

Nov 19th 2018: Playing with strokes in P5.JS and PubNub

Using Pubnub’s server to connect P5’s javascript messages I started to play with the idea of colours and strokes. I experimented with a couple of outputs and even thought about having the same traced strokes projected on the digital canvas too with other characteristics but later felt the traced strokes would hinder the ambiguity I was aiming for. I also noticed that I was outputting the same randomization of colours and strokes both on mobile and on the desktop which was not what I wanted.

After a discussion with my professors I realized that all I needed to do to distinguish different characteristics from the strokes I inputed and then later outputted was to create another javascript file that would only publish the sent variables I wrote in my ellipse syntaxes:

Nov 22nd and 23rd 2018: Final Touches and Critique Day

On the eve of the critique I managed to create two distinguishable strokes: Ordinary simple strokes on one html page with it’s own JS file and vibrant stroke outputs for the other. The connection was successful. I decided to add triangles to the vibrant strokes and play around with the opacity to give the brush stroke more character. I later tested it along with another user and we both enjoyed how fun and fluid the interaction was.

Overall, the critique was an overwhelming success with a positive outcome. When the installation was projected in a public space users engaged and interacted with the strokes they displayed on the wall. Some got up and even took pictures as strokes danced around them and their silhouettes. It was a true celebration of user presence and engagement.

One of my biggest inspirations towards interactive installations that require user presence and engagement like ABSTRACT always lied in the works of Camille Utterback. Her commissioned work Abundance (2007) tracked the movements and interactions of pass-byers on the streets of San Jose plaza. This created interesting projections of colours and traces across the building. Many of Utterback’s work uses spatial movement and user presence to express a reflection of the life interacting and existing in the work’s space.
