Interactive tracking of movable objects for the blind on the basis of environment models and perception-oriented object recognition methods

Abstract: In previous work we have presented a prototype of an assistant system for the blind that can be used for self-localization and interactive object identification of static objects stored within 3D environment models. In this paper we present a new method for interactive tracking of various types of movable objects. The state of fixed movable objects, like doors, can be recognized by comparing the distance between sensor data and a 3D model. For the identification and model-based tracking of free movable objects, like chairs, we have developed an algorithm that is similar to human perception, based on shape and color comparisons to trained objects. Further, using a common face detection algorithm, our assistant system informs the user of the presence of people, and enables the localization of a real person based on interactive tracking of virtual models of humans.

Domain objects having computed attribute values for use in a freeform graphics system

Abstract: Domain objects for use in a freeform graphics system. Domain objects are context specific representations of information that are used in a freeform graphics system. Domain objects are represented in a freeform graphics system by a graphic object (icon) representing an instance of the domain object. The icon representing a domain object may be manipulated like any other graphic object. Domain objects are defined by a domain object class which define attributes, a set of action rules and layouts. The attributes describe the information or data associated with the domain object. The set of action rules map user actions and system events to operations that may be performed on the domain object. The layouts define how domain object information is displayed as an icon. The attributes may have computed values. An attribute have it's value computed based on the value(s) other attribute(s) or based on the spatial positioning of the icon representing the data object on a work surface.

User interfaces for designing objects

Abstract: A collaborative method of generating a design representation of an object between a first user and a second user is described. The method comprises: designating, at a first user terminal, a set of design object variables relating to different aspects of the design representation; specifying, at the first user terminal, constraints for the set of design object variables, the constraints comprising a range of first user designated values for each of the designated object variables of the set; receiving at a second user terminal, the set of design object variables, the constraints for the set and the design representation via a communication network; enabling, at the second user terminal, manipulation of the design object representation, the enabling step comprising enabling selection of a particular value of at least one of the designated object variables only within the constrained value range specified by the first user; and presenting on the second user terminal a graphical representation of the design object representation as specified by the second user selection.

Finding Boundary Objects in SE and HCI: An Approach Through Engineering-oriented Design Theories.

Abstract: This paper outlines an approach of using engineeringoriented design theories to build bridges between software engineering and human–computer interaction. The main thrust of the approach is to try to use design theories to create “boundary objects”, which are intellectual tools that are shared by both disciplines and enable cooperation. The approachis illustrated and supported by relating it to ongoing domain-bridging work which is exploring the application of cognitive support theories to SE research problems.
