Event

Students who have completed single semester independent work will be presenting at this session.

Join us for the COS424, Interacting with Data poster session.  Students will present their final projects on a variety of machine learning topics.

Students who have completed single semester independent work will be presenting at this session.

The COS 436 / ELE 469, Human-Computer Interface Technology class will have two demo sessions, one from 10AM-12PM, and the other from 1PM-3PM with 80 students presenting their work.

Students in the class were tasked with designing, building, evaluating, and refining a prototype system that involves tangible, embedded, gestural, non-visual, or otherwise novel interactions that move computing beyond familiar desktop, web, and mobile paradigms. Each project was also required to address some real-world problem. This is what students came up with:

Projects to be presented in the morning session, 10:00-12:00:

• ServiceCenter, a serving system for restaurants that allows waiters to efficiently manage orders and tasks by displaying information about their tables (Grupo Naidy)
• A device to improve security and responsibility in the laundry room (The Backend Cleaning Inspectors)
• A new musical listening experience using a jacket that vibrates with the bass (Team VARPEX)
• A “Kinect Jukebox”that lets you control music using gestures (Team X)
• NavBelt, a system for navigating around unfamiliar places more safely and conveniently (Team “Don't worry about it”)
• A Kinect-based system that watches people lift weights and gives instructional feedback to help people lift more safely and effectively (Team “Do You Even Lift?”)
• Runway, a 3D modeling application that makes 3D manipulation more intuitive by bringing virtual objects into the real world, allowing natural 3D interaction with models using gestures (Team CAKE)
• An add-on device for the cane of a blind user which integrates GPS functionality via bluetooth and gives cardinal and route-guided directions via haptic feedback (Group 17)
• A minimally intrusive system to ensure that users remember to bring important items with them when they leave their residences; the system also helps users locate lost tagged items, either in their room or in the world at large (The Elite Four)
• Oz, a system that authenticates individuals into computer systems using sequences of basic hand gestures (Group 21)

In the afternoon session, 1:00-3:00:

• A hardware platform that receives and tracks data from sensors that users attach to objects around them and sends them notifications, e.g. to build and reinforce habits (Team TFCS)
• The GaitKeeper, an insole pad that can be inserted into a shoe, and an associated device affixed to the user’s body, that together gather information about the user’s gait for diagnostic purposes (Team GARP)
• The PostureParrot, a system that helps user maintain good back posture while sitting (Team Colonial)
• A bowl, dog collar, and mobile app that help busy owners take care of their dog by collecting and analyzing data about the dog’s diet and fitness, and optionally sending the owner notifications when they should feed or exercise their dog (Team Chewbacca)
• A glove that allows users to control (simulated) phone actions by sensing various hand gestures (The Lifehackers)
• An interface through which controlling web cameras can be as intuitive as turning one’s head (Team Epple)
• A smart bookshelf system that keeps track of which books are in it (Team “%eiip”)
• An interactive and fun way for middle school students to learn the fundamentals of computer science without the need for expensive software and/or hardware (Team “Name Redacted”)
• A gesture bracelet for computer shortcuts (Team “Cereal Killers”)
• AcaKinect, voice recording software that uses a Kinect for gesture-based control, which is a more efficient and intuitive way of presenting a music recording interface for those less experienced with the technical side of music production (Team “Deep Thought”)

We hope to see you there! The demo session is open to anyone who would like to attend. For more information, please email me at fiebrink@princeton.edu or visit the course webpage at http://www.cs.princeton.edu/courses/archive/spring13/cos436/

Among the treasures discovered by the 1930s excavations at the ancient Roman city Antioch-on-the-Orontes (in modern-day Turkey) and its vicinity were numerous polychrome floor mosaics. One of these mosaics, depicting the drinking contest between Dionysos and Herakles, is one of the masterpieces in the Princeton University Art Museum's collection of ancient art. The mosaic originally decorated the pavement of the dining room in the eponymously named "House of the Drinking Contest," a third-century house in Seleucia Pieria, the port of the Roman city of Antioch-on-the-Orontes. The drinking contest and five other associated pavements were distributed to six museums, all but one in the United States.

The placement of the mosaics in museums has severed them from their original site and from each other. Excavation photographs show the mosaics in situ, but the absence of the original roofs and supporting walls altered the lighting conditions substantially. The ancient occupants would have seen sunlight as it entered the house over walls, through windows, and between columns, and moved across pavements during the course of the day and the arc of the year.

Computer science addresses the problem of the lost architectural and lighting contexts through a three-dimensional model that recreates the house and inserts the mosaics into the spaces that originally contained them. This computer model thus presents a graphic rendering of the hypotheses underpinning the architectural reconstruction. A programming script, which calibrates the sunlight to the latitude and longitude of Seleucia Pieria in the year 230 A.D., enables an accurate lighting simulation for the house and its mosaics. This simulation presents the lighting conditions at the summer and winter solstices of that year, and time-lapse videos allow the viewer to observe and study the movement of light throughout the house. Finally, the model places the viewer within the ancient spaces, thereby reconstructing and recontextualizing views from corridors within the house and from the house to the natural environment

Equilibrium problems in game theory are very useful to the understanding of economics and many other technical fields. In this talk, we will get an introduction to some computational techniques using large scale computing and Mathematica to help us find solutions to equilibrium problems.

Dr. John F. Nash is a Senior Research Mathematician at Princeton University. Nash received the 1994 Nobel Prize in Economics for his work in equilibrium problems.
