= Notes =

" The
innovative part of this project doesn’t concern the
technologies used but the new user experience modality
enabled by technology in order to access and manage
the contents.
The proposed interaction model is based on the post-
Wimp paradigm. The exhibition space is pro-active and
affords user’s senso-motorial patterns in order to
enhanced the experience of the user during the visit
through the “magic wand”. Being a completely
transparent tool it allows visitors to increase their
experience visiting the exhibition. The magic wand acts
as a mediator enabling the user to stay focused on the
exhibition instead of the tool of interaction." (abstract)

== HCI ((Human Computer Interaction) / direct manipulation==

"The principles of direct manipulation (Shneiderman,
1983) are fundamental concepts within the HCI (Human
Computer Interaction) leading the development of
graphical user interfaces towards Wimp (acronym that
stands for Windows, icons, menus and pointing device)."

== WIMP GUI (graphical user interface) intention ==

"The Wimp GUI
(Graphic User Interface) improves the human computer
interaction allowing a simple and easy access to the
applications and consequently it allows an increasing
amount of users."

== WIMP interaction model limits ==

"The Wimp GUI, even if supporting the user on his
activity better then the command-line environment,
doesn’t fill the semantic gap on the side of execution
between the intention and the execution of the action
(Norman, 1990)."

"The Wimp model is based on the fact that computers
have only keyboard and mouse as input devices that are
limited in comparison with the users set of actions. In
this perspective Wimp interfaces don’t solve the gap
between the users actions and set of commands. Even if
the Wimp model is a step forward in respect of the
command-line interface, a semantic distance between
formulation of intention and action execution still
remains."

== What is the WIMP interaction model  ==

"According to Beaudouin-Lafon the Wimp interaction
model (Beaudouin-Lafon, 2000) can be defined as:
application object displayed in document windows,
object can be selected and sometimes dragged and
dropped between different windows, commands are
invoked through menus or toolbars, often bringing up a
dialog box that must be filled in before the command’s
effect on the object is visible."

== Post-Wimp models ==

"The post-wimp interaction model has the
purpose to reduce this gap allowing an interaction
between the user and the manipulated object."

"In this paper we consider the post-Wimp model as a
distributed intelligent environment in which the user
interacts with objects in the real world to actuate
procedures or execute applications. With distributed
technology in the real world it is possible to embed
microprocessors in the object; an everyday no-technical
artefact could be transformed into a powerful tool."

"In our perspective the post-Wimp paradigm, artefacts
afford innovative senso-motorial patterns that enrich the
meaning of the user interaction creating an experiential
relationship with the environment. The proactive
environment can recognise the user profile adapting
information and services provided according with the
user preferences, attitudes and needs. Each component
of the architecture has to be aware of the context
connected with the other elements and integrated in the
community.
This post-Wimp model aims to re-introduce a semantic
dignity in human computer interaction.
This paper introduce a post-Wimp implementation of an
application based on ambient intelligence. The main
objective of this project is to substitute a traditional
input tool and user action connected to it, with common
objects and everyday gestures that could give a deeper
meaning to the action performed by the user."



=== About Memex ===

"Memex consists of a desk, and while it can presumably
be operated from a distance, it is primarily the piece of
furniture from where a user works. On the top are
slanting translucent screens, on which material can be
projected for convenient reading.
The Memex vision strongly inspired the concepts of
Desktop, Hyperlink and the research activity of the
Xerox PARC Lab and the Ted Nelson project Xanadu."

=== Other examples ===

"Currently, the most common examples of post-Wimp
interaction commercially available today are pen-based
handwriting recognition (such as Graffiti and Jot) used
in hand-held PDAs and TabletPCs (such as Penabled).
In these cases the user interacts with the Wimp interface
through a non Wimp object (touch screen technology
and the pen)"

=== Graspable interfaces (Fitzmaurice et al., 1995) ===

"In this kind of interfaces physical objects are
used as input devices to manipulate virtual objects. This
increases the user experience since interaction occurs in
the real world. An example of Graspable interfaces is
the Arcade games. The user interacts with the virtual
reality through objects such as joysticks, pads, steering
wheel and gear consoles. For example, in the golf
arcade games the player swings a real club and hits a
real ball. The ball trajectory is then simulated and
displayed on the screen."


=== About SIENA UNIVERSITY HISTORICAL MUSEUM AND ARCHIVE / hidden technology ===

The interaction between a kiosk and a magic wand is
hidden for the user. When the user interacts with the
kiosk placing the magic wand near the reader, the
currently visualised content on the screen are
automatically captured using the magic wand. The
Database on the Server is updated with the information
of which wand has been used in which room as well as
what information the user captured.
The complexity of this technology is completely hidden
to the user who can easily play with the magic wand and
enjoy the possibility to carry home the most interesting
contents and images.
