“Virtual Images for Similarity Retrieval in Image Database”, IEEE Trans.
on Knowledge and Data Engineering, vol. 13, no. 6, Nov.-Dec. 2001, pp.
951-967. Abstract We
introduce the virtual image, an iconic index suited for pictorial information
access in a pictorial database, and a similarity retrieval approach based on
virtual images to perform content-based retrieval. A virtual image represents
the spatial information contained in a real image in explicit form by means
of a set of spatial relations. This is useful to efficiently compute the
similarity between a query and an image in the database. We also show that
virtual images support real-world applications that require translation,
reflection, and/or rotation invariance of image representation. M. Sebillo, G. Tortora,
G. Vitiello, “The Metaphor GIS Query Language”, Journal of Visual Languages and Computing,
Academic Press, vol. 11, n. 4, 2000, pp. 439-454. Abstract In recent
years, visual representations have been increasingly used in the management
of real-world phenomena as a valuable support for human}computer interaction.
In the field of Geographic Information Systems, visual languages represent a
promising means for allowing unskilled users to query geographic databases.
In the present paper, we define the Metaphor GIS query Language (MGISQL)
which allows GIS users to simultaneously capture the spatial and the thematic
components of geographic data. MGISQL describes the semantic of those data in
the real world and is based on a special type of visual description, the geometaphor, which is used to specify all the elements
featured in a GIS domain. V. Del Fatto,

(Eds). Palgrave Macmillan Journals. Abstract When dealing with scenarios referring to complex issues, such as
political, economic and demographic problems, the usage of visual metaphors
represents a more effective approach in supporting users to locate facts and
new patterns. In this paper, we describe a research project whose aim is to
investigate a cartographic solution able to represent dynamics, movements and
changes that underlie possible problems. The solution we propose is based on
the chorem concept. It represents an immediate
synthesis of data of interest, and provides expert users with both a global
view of objects and phenomena, and an insight into a specific issue. Based on
preliminaries studies, we first provide a formal definition and
classification of chorems in terms of structure and
meaning, meant to homogenize chorem construction
and usage. Then, a system to generate chorematic
maps from available data sets is described and an XML-like language, named ChorML is specified, enabling system modules
communication. In order to validate our approach, we exemplify the
construction of a chorematic map, which depicts the
most significant flows of migrating population in Italy in 2000. Such a
synthesis may represent the starting point for further processing tasks aimed
to derive spatial analysis data, as well as to support expert users in
decision making. L. Paolino,

1748–9725 print/ISSN 1748–9733 online. 10.1080/17489720802487949 Abstract When using a mobile device for navigating and querying a map,
some visualisation and usability problems may arise
due to small screens and limited interaction modes allowed by such devices.
Recently, researchers have devoted their efforts to overcome these issues by
introducing innovative approaches for developing advanced interfaces, capable
of providing users with analytical information as well as visual summary of
data. In this article, we propose a new visualisation
technique, named Framy, which exploits a novel
interaction metaphor for picture frames to provide hints about off-screen
objects. It was conceived to cover a wider range of spatial data visualisation tasks, which may simultaneously involve
different geographic layers. The technique has been embedded inside a mobile
GIS application, MapGIS, designed to perform
typical GIS operations and queries on mobile devices. A usability study has
been performed in order to verify the benefits in efficacy, efficiency and
subjective satisfaction coming from the adoption of Framy
within the system. R. Laurini, L. Paolino,

doi:10.1016/j.jvlc.2009.06.002 Abstract The need to perform complex analysis and decision making tasks
has motivated growing interest in Geographic Information Systems (GIS) as a
means to compare different scenarios and simulate the evolution of a
phenomenon. However, data and function complexity may critically affect human
interaction and system performances during planning and prevention
activities. This is especially true when the scenarios of interest involve
continuous fields, besides discrete objects. In the present paper we describe
the visual environment Phenomena, where continuous and discrete data may be
handled through a uniform approach. We illustrate how users’ activity is
supported by a visual framework where they can interact with, manipulate and
query heterogeneous data, with a very small training effort. A preliminary
experimental study suggests that when users perform complex tasks, a higher
usability degree may be achieved compared to the adoption of a textual
spatial SQL. R.

“Computer-generated Visual Summaries of Spatial Databases: Chorems or not Chorems?”, Electronic Journal Sapiens, Volume
2(2), 2009. http://sapiens.revues.org/index795.html Abstract Chorems
can be defined as representations of elementary structure of a geographic
space or as schematized representations of territories, and as such they can
represent a good candidate for generating visual summaries of spatial
databases. Indeed for spatial decision-makers, it is more important to
identify and map problems than facts. Until now, chorems
were made manually by geographers who needed an exhaustive knowledge of the
territory under study, a clear-cut set of rules to decide what the salient
phenomena are, and who had no problems to cartography them. Here we present a
methodology based on spatial data mining, that both diminish the requirements
in terms of starting knowledge, and provide a more rigorous approach to
select the important features. S. Ricciardi, M. Nappi,

“Dependability Issues in Visual-Haptic Interfaces”
- Journal of Visual Languages and Computing, Elsevier. vol. 21(1), - 2010,
pp, 33-40. doi:10.1016/j.jvlc.2009.07.001 Abstract Dependability
of a system is commonly referred to its reliability, its availability and its
maintainability (RAM), but when this concept is applied to user interfaces
there is no common agreement on what aspects of user–system interaction are
related to a satisfactory RAM level for the whole system. In particular, when
dealing with haptic systems, interface
dependability may become a crucial issue in medical and in military domains
when life-critical systems are to be manipulated or where costly remote
control operations are to be performed, like in industrial processes control
or in aerospace/automotive engineering and manufacturing. This paper
discusses the role of dependability in haptic user
interfaces, aiming to the definition of a framework for the assessment of the
usability and dependability properties of haptic
systems and their possible correlations. The research is based on the
analysis of a visual–haptic-based simulator
targeted to maintenance activity training for aerospace industry which is
taken as a case study. As a result, we propose a novel framework able to
collect and then process relevant interaction data during the execution of haptic tasks, enabling to analyze dependability vs.
usability correlations. L. Paolino, M. Sebillo,

engines: the Search Tree visual language”, Software – Practice and Experience
Experience vol. 40(8), July 2010. John Wiley &
Sons, Ltd. Published online in Wiley InterScience
(www.interscience.wiley.com). DOI: 10.1002/spe.978, pp. 735-750. Abstract In this
paper, we describe the Search Tree visual language. It is a novel methodology
able to support users to build up complex queries to be run on given search
engines. For using this visual language, neither parentheses nor precedence
rules are needed, nor the specific ability to perform advanced search tasks.
The language is proven to have the same expressive power as the expressions
in Sum Of Product form. In order to prove the appropriateness of our
proposal, we measured the usability of the proposed querying approach against
the traditional YahooTM web search query
language. Results show that, even if both the approaches fully support users
in terms of efficacy, the Search Tree visual language significantly improves
task efficiency, both in terms of the number of actions performed and the
time requested with respect to the advanced search interface. L. Paolino, M. Sebillo, G. Tortora, G.Vitiello, “Integrating Discrete and Continuous Data in an
OpenGeospatial-Compliant Specification” in
Transaction in GIS, 14(6) (J.P. Wilson, A.S. Fotheringham
and D. O'Sullivan eds.) 2010 Blackwell Publishing Ltd. pp. 731-753. doi: 10.1111/j.1467-9671.2010.01231.x Abstract The integrated management of heterogeneous spatial data, such as
continuous fields and discrete data, is an important issue for the Geographic
Information (GI) community. Indeed, GI users are forced to navigate among and
operate with several tools in order to solve their spatial problems, due to
the lack of systems capable of integrating different components, each meant
to provide a specific solution. The aim of this article is to propose an OpenGeospatial-compliant solution which supports expert
users in handling problems involving heterogeneous data by means of a
seamless approach. A class hierarchy modeling spatial discrete objects,
continuous data, relationships, and operations, is described, whereby data
are organized in agreement with the binary representation. A running example
is illustrated to support readers’ understanding of the proposed solution.
Finally, some guidelines about an implementation modality are given, to
demonstrate the applicability of the proposal to an existing DBMS. L. Paolino, M. Romano, M. Sebillo,

Management through a Visualization Technique for Mobile Devices" Journal
of Location Based Services, 4(03-04), 2010. pp. 222 - 239. doi: 10.1080/17489725.2010. Taylor and Francis Group Ltd. Abstract In case of emergency, visual analytics applications may be a
successful means for quickly organizing necessary activities. They allow
decision-makers to immediately visualize the status of the crisis, plan the
evacuation and address people towards vacancies in emergency centres.
Although the effectiveness of such applications is immediately clear, further
support may be gained by allowing people to directly manage the emergency on
site. In this sense, it seems to be particularly desiderable
to provide interfaces which support visual analytics tasks on small and
handheld devices without losing their communicative efficacy. In this paper,
we adopt and extend a visualization technique, named Framy,
specifically conceived for visualizing in a very intuitive way a large number
of aggregates on very small devices. In particular, we show how it can reveal
suitable for the management of this kind of emergencies by embedding and
qualitatively aggregating both spatial and temporal information useful for
catching status and evolution of events. An example concerning an evacuation
scenario shows the Framy extended capability. D. De Chiara, V. Del Fatto, R. Laurini, M. Sebillo, G. Vitiello, "A chorem-based approach for visually analyzing spatial
data", to appear in
Journal of Visual Languages and Computing, Elsevier. doi
10.1016/j.jvlc.2011.02.001 Abstract The
need to support the activities of decision makers through highly interactive
visual environments has motivated the growing interest in the area of GeoVisual Analytics. New interactive visualization tools
are being envisaged to deal with large datasets in order to synthesize
information and perform complex analytical tasks. Along this line, our
research efforts have been focusing on new cartographic approaches which
could support daily analysts’ work by producing synthesis and presentation of
discovered patterns in a concise and understandable way. As a result, we have
proposed the adoption of chorems as an innovative
method to visually summarize information from spatial databases and we have
implemented an XML-based language, named ChorML,
able to both specify chorems characterizing a map
and store the information useful to their manipulation. The goal of the
present paper is to enhance the role that chorems
may play in geographic domains, by exploiting them also for querying and
accessing data associated with a phenomenon under investigation. To develop
this idea, we first extend the semantics associated with the chorem concept and define a set of operators useful for
the rapid analysis of spatio-temporal phenomena.
Then, starting from an initial prototype, we present a chorem-based
visual environment that integrates traditional interactive visualization and
analysis techniques. The environment is specifically conceived so that each
visual interaction task has a context-sensitive behavior, which allows users
to acquire specific information from the underlying spatial database.
Finally, we present an enhanced version of ChorML
language, able to support the new analysis functionalities on chorems. |
