Summary: This case study explains how we used two computer-supported cooperative work
(CSCW) frameworks to define collaboration-related user requirements and
experience attributes for Retail.Me, a new retail planning solution currently
being designed at JDA Software. Our focus is on how this kind of framework can
be used in industry and if one particular framework better answered our need to
define user requirements and experience attributes for collaborative software.
We explain how we configured each of the frameworks, how we reconciled them,
and how this helped us reach our goal of defining user requirements and
experience attributes for Retail.Me. At the end of this case study, we
highlight differences in using the two frameworks, discuss their respective
advantages and disadvantages and identify what we could have done to improve
our process of defining user requirements and experience attributes.

Summary: This paper introduces the TactoWeb tool. TactoWeb is a Web browser allowing
users with visual impairment to explore Web pages using tactile and audio
feedbacks. It is used in conjunction with the Tactograph device or the iFeel
mouse. We first present a comparative study of existing tools that give users
with visual impairment access to Web pages. The aim of this study is to
identify the capabilities and limitations of these tools in order to define
important features which are needed to improve navigation on the Web for users
with visual impairment. TactoWeb is designed to make spatial navigation
possible, with better audio and tactile feedbacks. It should be superior to
sequential exploration with only audio feedback.

Summary: This article presents research on making schoolbook illustrations accessible
for students with visual impairment. The MaskGen system was developed to
interactively transpose illustrations of schoolbooks into tactile graphics. A
methodology was designed to transpose the graphics and prepare them to be
displayed on the STReSS2, a refreshable tactile device. We experimented
different associations of tactile rendering and audio feedbacks to find a model
that children with visual impairment could use. We experimented with three
scientific graphics (diagram, bar-chart and map) with forty participants:
twenty sighted adults, ten adults with visual impairment, and ten children with
visual impairment. Results show that the participants with visual impairment
liked the tactile graphics and could use them to explore illustrations and
answer questions about their content.

Summary: This paper describes the development of 3D network applications with force
feedback for and with hospitalized children. These applications are built on an
innovative multimodal platform which includes networked 3D graphics, sound and
force feedback. One goal of this research is to improve the life quality of
children isolated in sterile rooms during their stay in the hospital by
providing them the ability to physically interact with other people and to
enjoy themselves. Another goal is to elaborate a haptic design methodology
where users are involved in the design process.
