Cof-e-bar uses the coffee ritual as a catalyst for social interaction, as well as a vehicle for collective engagement with technology. In this demonstration of the Internet of Things, Computer Vision and Augmented Reality transform paper cups and an ordinary glass tabletop into smart interfaces. The digitally enhanced objects enable visitors to visualize and navigate in real time the stream of information flowing through social media while enjoying some freshly brewed coffee. There are two iterations of the cof-e-bar, the first one augments an existing table while the second one, we fabricated our own table.
My involvement with this project was at RAD-UM (rad-um.com) in which I was one of the Lead Designers while overseeing the production and fabrication of the prototype.
The first iteration of the Cof-e-bar was presented at eMerge Americas 2015 at the Miami Beach Convention Center. This first prototype augmented an existing table with a glass tabletop surface. An adjacent table was fabricated to house the equipment necessary to augment the glass table. Here, a short throw projecter, infrared lamps and an infrared webcam was housed. Specifically for this conference, we've embedded the following hashtags into each paper cup: #eMerge2015, #IoT, #WiT, #RAD and #eGov as common hashtags used throughout the conference. Free coffee was given to visitors in which they would not only choose the coffee they'd like, but also the hashtag they'd like to see tweets and instagram photos from.

The second iteration of the Cof-e-bar was presented in the VIP lounge of Design Miami 2015. In this iteration we designed and fabricated our own custom table, allowing us to hide all the electronics and equipment necessary within the table itself. In order to detect the coffee cups on the tabletop and display accordingly, the inner space of the table had to be free of any objects, as a result, the structure had to be pushed outwards (see drawings and diagrams below). For this event, we re-programmed the fiducials indicative of the event: #DesignMiami, #ArtBasel, and #RAD.
