"Conversational" Dialogues In Direct-Manipulation Interfaces, David G. Novick
"Conversational" Dialogues In Direct-Manipulation Interfaces, David G. Novick
David G. Novick
This paper reports ongoing research in extending direct-manipulation interfaces by incorporating, via the direct-manipulation modality itself, interaction techniques that add kinds of language features associated with spoken conversation. The paper proposes means of implementing ways for a user of a direct-manipulation system to define new kinds of relations among objects in the interface.
Users And Uses Of Synchronous Business Communications Software, David G. Novick, Eleanor Wynn
Users And Uses Of Synchronous Business Communications Software, David G. Novick, Eleanor Wynn
David G. Novick
To help designers and authors understand users' intentions and work practices for synchronous business communications in a systematic way, we used ethnographic and task-analytic techniques to collect, analyze and classify evidence of the activities of potential users as they conducted their work lives. The interactions we observed among our users took place through a variety of modalities. We found eight categories of tasks for the collaborative or interactive work in which our subjects engaged. Based on these data, we were able to classify roles of potential users of synchronous business communications software into a set of "archetypes" that characterize their …
Hands-Free Documentation, Karen Ward, David G. Novick
Hands-Free Documentation, Karen Ward, David G. Novick
David G. Novick
In this paper, we introduce an analysis of the requirements and design choices for hands-free documentation. Hands-busy tasks such as cooking or car repair may require substantial interruption of the task: moving the pan off the burner and wiping hands, or crawling out from underneath the car. We review the need for hands-free documentation and explore the role of task in the use of documentation. Our central analysis examines the roles and characteristics of input and output modalities of hands-free documentation. In particular, we review the use of speech as an input modality, and then visual means and speech as …
An Interaction Initiative Model For Documentation, David G. Novick, Karen Ward
An Interaction Initiative Model For Documentation, David G. Novick, Karen Ward
David G. Novick
In this paper we propose a model of creation and use of documentation based on the concept of mixed-initiative interaction. In our model, successful single-initiative interaction is characterized by grounding of contributions, and successful mixed-initiative interaction is characterized by both grounding and agreement. Just as in spoken conversation, achievement of actual agreement depends on the intentions of both parties; agreement is achieved when the reader follows the documentation’s instructions. In fact, readers are not obligated to—and often do not—act according to the author’s intentions. By making these dynamics explicit, the model can aid authors in developing effective documentation. The paper …
Assessing Effectiveness Of Personality Style In Documentation, Kenneth Sayles, David G. Novick
Assessing Effectiveness Of Personality Style In Documentation, Kenneth Sayles, David G. Novick
David G. Novick
This paper extends previous work by other researchers that indicated that users of computers preferred a computer with a personality that was similar to theirs. We conducted a similar experiment, but looking beyond preference to see if the personality of documentation would make a difference in the user’s performance. Our data suggest did not indicate that personality match affects performance; and if such a relationship exists it is likely to be weak. We discuss the related research, describe our methodology, present our results, and describe their implications and limitations.
Plastic Presentation Of Control Data In Context-Awareness Environment, Anas Hariri, Johannes Petersen, Djilali Idoughi, Christophe Kolski
Plastic Presentation Of Control Data In Context-Awareness Environment, Anas Hariri, Johannes Petersen, Djilali Idoughi, Christophe Kolski
Professor Djilali IDOUGHI
The needs for re-adaptable presentations of supervision information are more necessary in the context-awareness environment whose environmental characteristics change frequently and the control data must be updated regularly into the Graphic User Interface (GUI), in order to provide efficiently to operators an accurate picture of the state of the system being supervised. The re-adaptation of GUI is necessary following each considerable changes in the context of use or in the measured data. We will suggest, in this paper, an approach that allows to generate GUI (in other word plastic GUI) capable to adapt dynamically at runtime to changeable context of …
Evaluating Software Engineering Processes In Commercial And Community Open Source Projects, Tony Wasserman, Eugenio Capra
Evaluating Software Engineering Processes In Commercial And Community Open Source Projects, Tony Wasserman, Eugenio Capra
Tony Wasserman
We describe a current study for obtaining information about management of commercial and community open source projects. We have interviewed and surveyed leaders of more than 75 open source projects. Questions focused on the styles of leadership and communication, with a technical focus on testing and quality assurance processes. This paper describes the methods used to identify and contact subjects, as well as the questions posed and some results.
Using Flossmole Data In Determining Business Readiness Ratings, Tony Wasserman, Ashutosh Das
Using Flossmole Data In Determining Business Readiness Ratings, Tony Wasserman, Ashutosh Das
Tony Wasserman
This paper is a preliminary report on using FLOSSmole data retrieved from open source repositories (forges) to calculate Business Readiness Rating scores.
Methods And Tools For Developing Interactive Information Systems: An Historical Perspective, Tony Wasserman
Methods And Tools For Developing Interactive Information Systems: An Historical Perspective, Tony Wasserman
Tony Wasserman
This paper describes the evolution of hardware and software technology over the past three decades, focusing on approaches for building interactive information systems and web applications. Successive generations of technology have used advances in hardware and software technology, along with increasingly sophisticated development methods and tools, to reduce development times and to produce a better user experience. After describing the key technology characteristics of each generation, this paper also describes the evolution of a specific methodology, User Software Engineering, from its origins in the 1970’s to its applicability to the development of modern applications.
Towards Web Services Oriented Unified Supervisory Hci, Djilali Idoughi, Christophe Kolski
Towards Web Services Oriented Unified Supervisory Hci, Djilali Idoughi, Christophe Kolski
Professor Djilali IDOUGHI
A lot of work & research has been done in HCI supervision-type industrial context, but mostly relative to control rooms and local supervision. However, many multi-site or extended and complex organisations are faced with some new challenges and trends such as supervisory systems integration and unified access of the different actors which have not been much considered so far. A service oriented solution is outlined and explained in the context of industrial supervision oriented towards to a unified and integrated supervisory HCI design. A representative supervisory scenario taken from a real case study which illustrates the approach is then described.
A Busy-Tone Based Mac Scheme For Wireless Ad Hoc Networks Using Directional Antennas, Hong-Ning Dai, Kam-Wing Ng, Min-You Wu
A Busy-Tone Based Mac Scheme For Wireless Ad Hoc Networks Using Directional Antennas, Hong-Ning Dai, Kam-Wing Ng, Min-You Wu
Hong-Ning Dai
Applying directional antennas in wireless ad hoc networks offers numerous benefits, such as extended communication range, increased spatial reuse, improved capacity and suppressed interference. However, directional antennas can cause new location-dependent carrier sensing problems, such as new hidden terminal and deafness problems, which can cause severe penalties to the performance. Recently, a few schemes have been proposed to tackle these problems. However, these methods can provide limited solutions on the hidden terminal and deafness problems. We propose a new MAC protocol, termed the busy-tone based directional medium access control (BT-DMAC) protocol. When the transmission is in progress, the sender and …
