With the introduction of software agents and assistants, the concept of so-called social user interfaces evolved, incorporating natural language interaction, context awareness and anthropomorphic representations of visuals, scales, and degrees of freedom for interactions. Today’s challenge is to build a suitable visualization architecture for anthropomorphic conversational user interfaces, and ...

This paper advocates a new metaphor for designing threedimensional Augmented Reality (AR) applications, Tangible Augmented Reality (Tangible AR). Tangible AR interfaces combine the enhanced display possibilities of AR with the intuitive manipulation and interaction of physical objects or Tangible User Interfaces. We define what Tangible AR interfaces are, present some design guidelines and prot...

A natural language query interface for databases provides the user friendliness in retrieving the desired information by querying in a native natural language. Up to now, many natural language query interfaces for conventional databases have been developed. However, the eld of natural language query interfaces for object-oriented databases which have recently started to emerge as the next-gener...

Traditionally computer games are played with a keyboard and a mouse or a joystick. The playing relies mainly on visual and auditory senses. Tactile or haptic user interfaces and natural movements of the human being, e.g. running, are seldom utilised in computer games. The Lumetila project (Virtual Space – User Interfaces of the Future) aims at developing a "natural" user interface in a computer...

In the geolocation field where high-level programs and low-level devices coexist, it is often difficult to find a friendly user interface to configure all the parameters. The challenge addressed in this paper is to propose intuitive and simple, thus natural language interfaces to interact with low-level devices. Such interfaces contain natural language processing and fuzzy representations of wo...

ost current Uls are fairly similar and belong to one of two common types: either the traditional alphanumeric full-screen terminals with a keyboard and function keys, or the more modern WIMP workstations with windows,/cons, menus, and a pointing device. In fact, most UI standards released since 1983 have been remarkably similar, and it is that category of canonical windOw system that is referre...

Handoff of objects and tools is a common action in face-toface collaborative work. Handoff is one of the low-level actions of collaboration that are smooth and natural in physical settings, but that are not usually considered in the design of digital workspaces. To better inform the design of these systems, we carried out a study that looked at the details of where and how handoff occurs in two...
