• Multitoe
  an interactive floor, based on FTIR
• Lumino
  a system of building blocks that allows microsoft surface to sense building elements arranged in three-dimensional structures
  
• Data Miming
  Users retrieve 3D objects from a database by tracing their outlines in 3-space
  
• Imaginary Interfaces
  devices that allow users to interact spatially as they normally would with a touch screen--yet without the screen
• Touch on Curved Surfaces
  Technology is emerging that allow touch-enabling non-planar surfaces
• Understanding touch 
  In order for a touch device to be highly effective it needs to match users' mental model of touch. But what is that model?
  
• Generalized perceived input point model & ridgepad
  We find that the touch location sensed by capacitive touchpads varies across users and finger postures. We build a device based on a fingerprint scanner that exploits this.
• Nenya
  This input device is a passive magnetic ring. We obtain this tiny device form-factor by offloading all electronics into a bracelet that tracks the ring using a magnetometer.
• Relaxed Selection Techniques
  allow users to search time series data using a pen stroke that not only specifies the shape of the sought segment, but also specifies tolerances
• My new PC is a mobile phone
  the computational device for the world is already here - it is mobile phones. 4 billion of them. But to make them useful, we need to create new software that turns phones into stand-alone computers.
• Nanotouch
  a prototype device that users operate via the device backside. Allows for making very small mobile devices.
• Disappearing Mobile Devices
  devices so small, that they only allow certain types of gesture interactions: a thought experiment about the ultimate future of mobile miniaturization.
• Touch Projector
  allows users to manipulate the contents located on distant public displays by touch manipulating its video image on their mobile device.
