AR User Interfaces Interaction Techniques for Augmented Reality in Head-Mounted Displays
A new generation of head-mounted displays such as Microsoft HoloLens, EPSON Moverio, and ODG devices are able to generate 3D content which seems to exist in the real world around us. A major challenge is how to interact with such digital content, including input devices and interaction techniques as well as the corresponding UI paradigms and elements to support such input.

ColorCorrectionIcon Color Correction on Transparent (Optical See-Through) Displays
Transparent displays, whether used for spatial augmented reality or for head-mounted displays, are subject to color blending — users perceive color as a combination of the display color and the background. In this project we investigate the theoretical foundations of color blending, and propose practical solutions to this problem by means of color correction algorithms. Our results not only outperform existing solutions, but also do so without requiring extra hardware and in real-time.

ConsumedEnduranceIcon Consumed Endurance (CE) – Arm Fatigue in Mid-Air Interactions
Consumed Endurance (CE) is a metric that captures the degree of arm fatigue during mid-air interactions. Based on the bio-mechanical structure of the arm, CE can assist with the design of minimally fatiguing gestural interfaces. CE derives its validity from a strong to perfect correlation to the Borg CR10 scale for physical exertion.

tPadIcon tPad – Transparent-Display Mobile Devices
Transparent display mobile devices have long been the focus of science fiction and design concepts for future technologies. However, research is scarce about the actual benefits they can bring to mobile interactions. This project explores how transparent display mobile devices can help everyday mobile tasks such as task switching and photo capture. We present two different prototypes and discuss technical challenges.

Mediated Tabletop Interactions
In this project we explore tangible interactions on a tabletop with objects which are too small to be tagged with fiducial markers or to be tracked with a camera. Our approach, called Mediated Tabletop Interactions, uses an intermediate device to identify the objects and communicate their location and orientation to the tabletop. Our prototype, the Rabbit, was design to support the integration of laboratory test tubes and tabletops.

In this project we explored the use of ambient information displays to induce behaviors which people perceive as voluntary. GridOrbit is set of distributed public displays which motivate users to donate computational power to a volunteer computing infrastructure (see the MiniGrid below). An in-the-wild study of GridOrbit showed a significant increase in the number volunteers and their contribution levels after the introduction of the displays.

InterruptMe provides users with awareness of a colleague’s availability. InterruptMe provides availability information tailored to the communication medium and personal relationship, implements an asymmetric-traceable approach, and delivers information by means of implicit interaction. InterruptMe uses a set of sensors to capture availability information and support the triggers for implicit interaction.

TIDE (a.k.a. PhoneVortex)
TIDE explores the integration between smartphones and interactive tabletops. Our goal is twofold. By integrating the smartphone to a large tabletop display, the smartphone application gain a large display real state for a better user experience, particularly in collaborative settings. On the other side, using applications loaded on a smartphone circumvents the shortage of applications available for such devices and the possible privacy issues associated to using your personal data on a public tabletop.

P2P Game Network Framework
Multiplayer games require a network infrastructure to communicate and synchronize the devices of each player. In this project we built an framework for making those connections in a P2P fashion, avoiding any central controlling entity.
