This paper describes the results of an experiment comparing the effectiveness and the impact of three kinds of usual architectural representation (plan, mock-up and virtual visit of a 3D model) for the perception of ambiances. We compare the judgments of people (inexperienced in the architecture domain) on 32 ambiance criteria, made on the basis of one of these representations. We compare these judgments on those made by the same participants on the basis of a visit of the real space. We conclude on propositions to enhance representation of ambiances in architecture.

This paper investigates issues related to the use of mobile social applications which aim at supporting coordination and communication, and enhancing the feeling of connectedness and social presence. To explore these assumptions, we conducted an empirical study of an application that enables group of users to share awareness information about their status and location. We present the results of the study, focusing on three issues: patterns of usage of awareness information, evolution of the usage, and privacy.

UniGuide is a support system to use the Unistroke gesture keyboard. It is based on dynamic guides to help the user to perform the gesture associated with the character he wants. To enhance the visual feedback, the guides are spread over several pages through the use of a prediction module language. An initial experiment showed a good satisfaction rate. But the switch between pages is overused and the guides slow down the users who seem to perform more precise gestures indeed slower.

Nowadays, linguistics and language processing represent an important part of the text entry domain. Prediction and/or automatic correction systems are often included in mobile devices with text entry capabilities. However, in gesture based text entry, few such systems are known. We propose UniWise, a system which combines Unistrokes, a gesture alphabet, and LetterWise, a disambiguation system. Our purpose was to study the fusion of the results from the gesture recognizer and results of the prediction system. Our system was tested with several fusion functions. The best function showed a theorical improvement of the recognition error rate of 17,23%. An experiment was conducted to measure the impact on user performance. The result was an improvement of 17,26% in the recognition error rate in the three last sessions and an improvement of 1,04 for the position of the correct character in the recognition result list. According to user feedback, the LetterWise component was transparent to the users.

This research focus on the effect of number of options of message of Interactice Voice Response, or IVR, (recorded human voice) multiple option messages and on the effect of linguistic marker on memorization of options. Participants were told to pay attention to the quality of speech interactions between users and an IVR system with a natural voice. They asked to recall system messages which suffixes were added. The suffix was either experimental (pseudoword), natural ("It's your turn [to speak]") or control (beep). Results showed that option recall was impaired when messages were longer and contained a suffix. These results confirm and specify recommendations for IVR prompt design.

This paper describes two tabletop interaction techniques for collocated collaborative work. These techniques aim to improve the transitions between individual and collective tasks to improve the collaborative interaction. The first technique is based on common document browsing techniques with the decomposition of the browser into independent components to desynchronize the interaction and to avoid interruptions in collocated users' work. The second technique gives a means to launch graphical objects on the interface without disturbing other users. This technique allows the user to implicitly give the desired orientation and dimensions of the new window before it is displayed on the interface.

While model-based approaches have been used for over 30 years in the field of behavioral description of interactive systems [27], the link between these approaches and user-centered design process remain insufficiently explained. This paper offers a contribution to this problem by presenting how a model-based approach can be exploited to facilitate the tasks of evaluation of usability that are often laborious and repetitive. The basic principle of this approach promotes the use of recording and analysis of log data in a model-based environment. The results described in this paper show that the log data at model level can be used not only to identify usability problems but also to identify changes to these models in order to correct the encountered problems. This approach is integrated in a process and is supported by a modelbased CASE tool for modeling, simulating and evaluating interactive systems. The case study illustrates the principles of the approach and operation of the tool on an interaction technique. It shows how the analysis of log data allows the designer to easily tune the interaction technique (as the results of the analysis of log data are presented at the same abstraction level than models). It proposes an alternative to user tests that are very difficult to configure and to interpret especially when advanced interaction techniques are concerned.

The CubTile is a cubic-shaped device with 5 tactile multi-touch faces. It was initially designed for 3D interaction. In this article we explore its use for navigation and pointing in a 2D space. In this way, we propose a bi-manual interaction technique, based on the manipulation of two faces of the CubTile, in a focus+context interface: The non-dominant hand pans the focus with one face of the CubTile while the dominant hand points in the focus area using another face of the CubTile. The results of a first user experiment indicate that an asymmetric tuning, with a low amplification for the non-dominant hand gestures and a high amplification for the dominant hand gestures, provides better performance in a pointing task. These results are a first step towards optimal tuning of the tactile faces for asymmetric bimanual interaction.

Whether they buy online or not, people do shop on the Web and search for product or service-related information. This research extends a previous Web site evaluation study of twenty-one Web sites pertaining to four industrial sectors (i.e.; financial institutions, renovation, electronics and travel). The sites were evaluated for effectiveness, quality, and consumer satisfaction by a very large sample of consumers, asked to search for specific information. Analysing this data with various statistical techniques, we have confirmed the structure of the the Netqu@l grid to evaluate the quality of service, measured the relative contribution of each factors to influence the Web site effectiveness and the customer satisfaction and ordered them. The results show that usability is the dominant factor for site effectiveness, along with quality and quantity of information. Personnalization is most contributive to global satisfaction with the site, followed by ease of use. Paper limitations are adressed and promising future research venues are also proposed.
