Over time, many people accumulate extensive email repositories that contain detailed information about their personal communication patterns and relationships. We present three visualizations that capture hierarchical, correlational, and temporal patterns present in user's email repositories. These patterns are difficult to discover using traditional interfaces and are valuable for navigation and reflection on social relationships and communication history. We interviewed users with diverse email habits and found that they were able to interpret these images and could find interesting features that were not evident to them through their standard email interfaces. The images also capture a wide range of variation in email practices. These results suggest that information visualizations of personal communications have value for end-users and analysts alike.

Since the early works in the W3C Semantic Web initiative, RDF has been generically indicated as a potential basis for legally binding exchange of semantically structured information. In this paper we introduce and detail a procedural framework that could support such legally binding exchange. The proposed methodology is based on a Copyright Ontology, a copyright conceptualisation which includes concrete rights expression languages like MPEG-21 REL, and RDF model decomposition based on the Minimum Self Contained Graph theory. The procedure seems particularly useful when applied to P2P semantic web scenarios.
Statistical social science databases present many unique data management problems. Among them is the fact that computer-aided use of statistical social science data is subject to serious but preventable errors in data...

Proximity-based interaction through a long cane is essential for the blind and the visually impaired. We designed and implemented an obstacle detector consisting of a 3D Time-of-Flight TOF camera and a planar tactile display to extend the interaction range and provide rich non-visual information about the environment. Users choose a better path after acquiring the spatial layout of obstacles than with a white cane alone. A user study with 6 blind people was analyzed and showed extra time is needed to ensure safe walking while reading the layout. Both hanging and ground-based obstacles were circumvented. Tactile mapping information has been designed for representation of precise spatial information around a blind user.

To allow for producing high quality tactile graphics, the in- volvement of blind users in the production process can be a very vital approach. In this paper, we describe a col- laborative tactile graphic workstation. Thereby, a sighted user works with a conventional vector graphic production software while a blind user can edit the same graphic on a two-dimensional pin-matrix device at the same time. The software architecture as well as the tactile user interface is described. Furthermore, some conflicts that can occur in a synchronous collaboration task within the system are dis- cussed.
