"Conversational" Dialogues In Direct-Manipulation Interfaces, David G. Novick Oct 2007

"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 Oct 2007

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 Oct 2007

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 Oct 2007

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 Oct 2007

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.


A Canonical Seed Assignment Model For Key Predistribution In Wireless Sensor Networks, Patrick Tague, Radha Poovendran Sep 2007

A Canonical Seed Assignment Model For Key Predistribution In Wireless Sensor Networks, Patrick Tague, Radha Poovendran

Patrick Tague

A promising solution for trust establishment in wireless sensor networks is the assignment of cryptographic seeds (keys, secrets, etc.) to sensor nodes prior to network deployment, known as key predistribution. In this article, we propose a canonical seed assignment model for key predistribution characterizing seed assignment in terms of the probability distribution describing the number of nodes receiving each seed and the algorithm for seed assignment. In addition, we present a sampling framework for seed assignment algorithms in the canonical model. We propose a probabilistic k-connectivity model for randomly deployed secure networks using spatial statistics and geometric random graph theory.We …


Preliminary Model Tests For The Design Of A Gliding Deep Water Elevator, Christopher Roman, T. Gregory, E. Martin, A. Sanguinetti, J. Drummond Aug 2007

Preliminary Model Tests For The Design Of A Gliding Deep Water Elevator, Christopher Roman, T. Gregory, E. Martin, A. Sanguinetti, J. Drummond

Christopher N. Roman

This paper presents progress on the design of a "smart elevator" to be used in conjunction with deep sea ROV operations. Deep sea elevators are gravity driven untethered platforms used to deliver and or return items from the sea floor. Elevators are used when items are too large or heavy to be handled by the ROV, or when the turn around time to recover and redeploy the ROV system for sample removal is prohibitive. Unfortunately, efficiency is complicated by the precision with which elevators can be landed at a specific location on the bottom and recovered on the surface because …

Design Of A Gas Tight Water Sampler For Auv Operations, Christopher Roman, R. Camilli May 2007

Design Of A Gas Tight Water Sampler For Auv Operations, Christopher Roman, R. Camilli

Christopher N. Roman

This paper presents the design and preliminary test results for a small gas tight water sampler intended to work on scientific AUVs. In recent years AUVs have developed into reliable platforms capable of carrying a wide variety of environmental sensors for in-situ chemical measurements. Physical sample collection however remains difficult, due to the combination of space, power and complexity constraints inherent in working with autonomous platforms. The AUV sampler is a small (12 cm times 85 cm) cylindrical package designed to collect eight 20 ml gas tight volumes of water, with each sample maintained at high pressure to depths of …


Plastic Presentation Of Control Data In Context-Awareness Environment, Anas Hariri, Johannes Petersen, Djilali Idoughi, Christophe Kolski May 2007

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 …

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 Dec 2006

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 Dec 2006

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 …
