We introduce a new accurate and technology independent display color characterization model for color rendering of multispectral images. The establishment of this model is automatic, and does not exceed the time of a coffee break to be efficient in a practical situation. This model is a part of the color management workflow of the new tools designed at the C2RMF for multispectral image analysis...

We have built and operated a tactile vision substitution system based on 48 piezoelectric actuators assembled in a movable tactile output unit. The unit can be positioned at any location on a two dimensional surface to explore the line structure of a virtual image. This virtual tactile display (VTD) receives data either from camera systems equipped with suitable image processing capabilities or...

Across domains, researchers, engineers, and designers are faced with large volumes of data that are heterogeneous in nature including spatial, abstract, and temporal information. There are numerous design and technical challenges when considering the unification, management, and presentation of these information types. Most research and applications have focused on display techniques for each o...

It is commonplace to present virtual world interactions as a three-dimensional display – such as may be generated using a virtual camera. Even though these ‘stealth’ or ‘magic carpet’ displays are popular, effective presentation of information in this format is a challenging problem. Unskilled operators often select viewpoints that present confusing information to viewers. This paper examines t...
