In this paper, we present linguistic techniques required for natural language driven knowledge management interfaces. We describe two significant aspects of such an interface: First, how the user input is handled to provide an unrestricted natural language user interface, and second, how the gathered knowledge should be preprocessed, classified and thus prepared for a natural language interacti...

This paper proposes a novel tabletop display system for natural communication and flexible information sharing. The proposed system is specifically designed to integrate two-dimensional (2D) and three-dimensional (3D) user interfaces by using a multi-user stereoscopic display, IllusionHole. The proposed system takes awareness into consideration and provides both 2D and 3D information and user i...

Distant pointing at large displays allows rapid cursor movements, but can be problematic when high levels of precision are needed, due to natural hand tremor and tracking jitter. We present two ray-casting-based interaction techniques for large high-resolution displays – Absolute and Relative Mapping (ARM) Ray-casting and Zoom for Enhanced Large Display Acuity (ZELDA) – that address this precis...

Natural language generation technology is now ripe for commercial exploitation, but one of the remaining bottlenecks is that of providing NLG systems with user-friendly interfaces for specifying the content of documents to be generated. We present here a new technique we have developed for providing such interfaces: WYSIWYM editing. WYSIWYM (What You See Is What You Meant) makes novel use of th...

This paper discusses the development of graphical user interfaces (GUIs) to illustrate sampling from a trinomial distribution by the natural extension of Galton’s Quincunx to three dimensions.

Automotive user interfaces and, in particular, automated vehicle technology pose a plenty of challenges to researchers, vehicle manufacturers, and third-party suppliers to support all diverse facets of user needs. To give an example, they emerge from the variation of different user groups ranging from inexperienced, thrill-seeking young novice drivers to elderly drivers with all their natural l...

The Wizard of Oz (WOz) technique is a mechanism for the experimental evaluation of user interfaces. It allows the observation of a user operating an apparently fully functioning system whose missing services are supplemented by a hidden wizard. From our analysis of existing WOz systems, we observe that this technique has primarily been used to study natural language interfaces. With recent adva...

Natural language interfaces to databases are not in couunon use today for two main reasons: they are difficult to use and they are expensive to build and maintain. This paper presents a functional overview of a new kind of natural language interface that goes far in overcoming both of these problems. The “ease-of-use” problem is solved by wedding a menu-based interaction technique to a traditio...

Natural language (NL) user interfaces are growing in popularity. Unfortunately, the complexity of NL interaction makes these interfaces difficult to design. For NL interfaces to become successful, universal tools are needed to help support the NL design process. What work practice should these tools explicitly support? Interviews with NL designers and our own experiments have identified a speci...

Hand motion sensing-based interaction, abbreviated as ‘free-hand interaction’, provides a natural and intuitive method for touch-less interaction on large display. But due to inherent usability deficiencies of the unconventional size display kinematic limitations user’s arm joint movement, display-based free-hand is suspected have different performance across whole areas To verify this, multi-d...
