We present Mockup Builder, a semi-immersive environment for conceptual design which
allows virtual mockups to be created using gestures. Our goal is to provide familiar ways for …

In the last years, BIM has gained interest across the construction sector in Europe. 3D
coordination, ie the task aiming at comparing several 3D models in order to reduce …

Stereoscopic tabletops offer unique visualization capabilities, enabling users to perceive
virtual objects as if they were lying above the surface. While allowing virtual objects to …

Modern tablets support simultaneous pen and touch input, but it remains unclear how to best
leverage this capability for bimanual input when the nonpreferred hand holds the tablet. We …

Multitouch surfaces are becoming prevalent, but most existing technologies are only
capable of detecting the user's actual points of contact on the surface and not the identity …

Virtual Reality (VR) is again in the spotlight. However, interactions and modeling operations
are still major hurdles to its complete success. To make VR Interaction viable, many have …

Bimanual pen and touch UIs are mainly based on the direct manipulation paradigm.
Alternatively we propose partially-indirect bimanual input, where direct pen input is used …

The latest innovations of VR make it possible to construct 3D models in a holographic
immersive simulation environment. In this paper, we develop a user-friendly mid-air …

Tablets are attractive for design work anywhere, but 3D manipulations are notoriously
difficult. We explore how engaging the stylus and multi-touch in concert can render such …

In architectural design, pencil and paper remain the most frequently used media to create
freehand drawings to support early design stages. Digital tools conventionally used by …
