Chalkaat: Augmented Reality Laser-cutting

Present day laser cutting tools allow users to do subtractive manipulation of material, hence democratizing manufacturing. However, we felt that the methods to manipulate such machines aren’t yet evolved enough.  Hence we present, a pen stroke based UI for interacting with laser cutters, where the users can express themselves more directly by working directly ‘ on the workpiece’. Different colored markers allow different commands to be executed. We built a laser cutter from ground up, with computer vision and mechanics to optimize for the interface. In team with: Nitesh Kadyan, Meghana Bhat, Fabio Besti

Kaala- Printer contraption that runs on soot from pollution for updates Black printing ink is one of the most consumed products in the industry. Most of this printing ink is produced in factories with complex chemical procedures. Companies like HP/Canon make 70 percent of their profits by selling these cartridges at 400% margin. This is not an attempt to win over the pollution. Just a minor itch that led me to build something cool from observations arising from nostalgia of the days back in India. There’s so much soot/pollution around us, esp. in crowded cities. What if the same could be repurposed to generate ink for printers?…


Sevenbyfive tessellations

Sevenbyfive is an interactive architectural surface that has the ability to scale and bend out plane at the same time. We create a “second-order” four-way linkage mechanism to  achieve this. Generic ball and socket joint connectors allow out of plane movements. We handcasted 800 components over a period of 5 days and motorized them.

Glassified: Augmenting a traditional ruler with digital functionality

We introduce Glassified, a modified ruler with a transparent display to supplement physical strokes made on paper with virtual graphics. Because the display is transparent, both the physical strokes and the virtual graphics are visible in the same plane. A digitizer captures the pen strokes in order to update the graphical overlay, fusing the traditional function of a ruler with the added advantages of a digital, display-based system. We describe use-cases of Glassified in the areas of math and physics and discuss its advantages over traditional systems. Anirudh Sharma, Lirong Liu, Pattie Maes The Ruler is embedded with -> TOLED…

Urino-Doc: An integrated medical advice interface

[Work in progress] Recently I visited a commercial doctor chain in India for a small medic diagnose. I was given a small plastic bottle to pee into and return back for a diagnose on a later date. During my exit at the payment counter, around five more people had similar bottles. That’s where it all began. Jaideep, victim to the previous shoe hack and I began some research back home about what could be done to ease an interface about using urine content data and health reporting. This below statement was inspiring to us: Most signs of an impending human ailment can…


LECHAL: haptic feedback based navigation shoe (for the blind)

I started Lechal as a DIY project in 2010. After 5 years Le-chal has evolved as a full-fledged lifestyle product now. Lechal was started in 2010 with a simple sketch and an Arduino lilypad prototype. This made me quit my job at HP Labs, which HP mentioned. After 6 months of initial demos, Krispian and I decided to pursue Lechal further as a product 🙂 We were introduced to each other magically by a visually impaired person. Lechal was started as a navigation aid for the visually impaired. At present people with limited or no vision depend either on walking canes, which help…


MozArt: Multimodal 3D UI for conceptual modeling

Motivation- 3D modeling has been revolutionized in recent years by the advent of computers. While computers have become much more affordable and accessible to the masses, computer modeling remains a complex task involving a steep learning curve and extensive training. According to a survey 80 percent people want to model/create to visualize their imagination using their computers, however the difficult UI of such tools prevents them from doing so. Even to model something the user has to go through the obtrusive set of icons/toolbars/features which are rarely used. We propose a computer modeling interface to bring it to common layman who…

Fluid in-fluid

‘Fluid in-fluid’ explores the mingling of liquid colours into water and tries to capture the mixture into an interactive light-form.  We wanted to develop a computer-less/tangible form for the same(though computers were used for the prototype). The prototype was demo-ed at a non-profit exhibit in Bangalore. Water is the base, transparent as PNG’s background. Colors mix according to Munsell color theory and visualize in form of artificially connected lights The work can be replicated by: Using RGB lights Arduino RGB Camera mounted below the table. Using Munsell color library in VVVV/Processing. The precision of mixing can be improved by using a…


Stethoscope to heartbeat monitoring

I’ve been toying around with the idea of heartbeat monitoring and the possibilities it has. Hence, I modified an old stethoscope, interfaced it to a Microphone, and used a line-in input to machine. Presently I am trying to get a realtime visual interpretation of whats beating inside our bodies. Maybe this could be extended to cloud where real-time analysis is possible. Presently electronic stethoscopes cost anywhere between 200-400$ and are limited by their functionality(as they just display a graph/bpm). The aim is to create an interface between our bodies and visual/network power of computers. [idea] What if music devices could change…
