In our work, we describe a new writing device created by Livescribe: the Smartpen.
This is an intelligent pen that is very much used now, especially in the academic
community. It distinguishes itself from the ordinary pens due to its innovative and
computational functionalities, because this type of pen allows the user to record his
notes, audio files and also gives him moments of leisure with the many different
applications. In this work, we also suggest some improvements that we consider
important, according to our experiments, as well as some different features.
What is the Smartpen?
The Livescribe Smartpen is an advanced paper-based computer in the form of a
pen that records everything that we hear and write. It synchronizes the audio that
we are hearing to what we are writing, so we never miss a word. To do so it is only
necessary to tap on our notes and the Smartpen will play back what we recorded
from that exact moment in time.
The Smartpen provides both audio and visual feedback, powerful processing
capabilities, and substantial built-in storage. The Smartpen integrates several
components and technologies. It also uses firmware and application software to
support the interaction of all of its components and to enable built-in handwriting
recognition, and applications such as Paper Replay, among many others.
After we had tested all the available applications in the SmartPen Pulse, we had
registered some observations.
Starting with piano application, we found it very explanatory because the pen itself
informs the user about what he has to do. We tested all the different rhythms as well as all the existing instruments. For that, we used the symbols r for the rhythm
and i for the instrument, stating its good efficiency.
The second application that we tested was the Paper Replay. Initially we had some
difficulties when we wanted to replay a recorded session. Since we had never
used this type of pen before, in our first utilization we found the navigation between
the menus a little confusing, and only after some interactions we could understand and use this application quit well.

recognition, and applications such as Paper Replay, among many others.
When we switch on the Livescribe Smartpen and begin writing on Livescribe dot
paper, the Smartpen captures and stores the notes that we write. To capture our
writing, the Smartpen uses its built-in infrared camera to take digital snapshots of a
special dot pattern on the paper as the tip moves over the paper while we write.
Features of the Smartpen
The SmartPen is able to write, to record, to replay audio files and also to transmit
information to other devices.
Beside these basic features, the SmartPen has other applications such as a
translator demo, a dictionary, games, and it also possible to personalize it in the
way that the user wants.
These features are described as follows :
• Paper Replay - When we begin recording with the Smartpen, it automatically
links the audio to anything we write on the dot paper. The recorded audio (and any
associated written notes) is called a Paper Replay session. A session begins
when we start recording audio and ends when we stop recording audio. A paused
recording is still one session. A session always contains audio and optionally can
contain associated written notes. The Paper Replay playback controls such as
jump, position bar, and bookmark, function within a single session. It is possible to
jump forward or back or speed listen to only one Paper Replay session at a time.
• Translator Demo - With this feature, we can translate a small set of words and
the numbers zero to nine from English into Spanish, Swedish, Arabic, or Mandarin.
By writing a word in English in the notebook, it is possible to see and hear correct
translation from the Smartpen.
•Piano - With the Piano application, we can draw a piano keyboard on our dotted
paper and play music with the Smartpen. Also, we can change the sound of our
piano, add rhythm tracks, and add sharp and flat notes. Writing the letters i and r
allows the user to change the instrument and the rhythm, respectively, by simply
The third application tested was the Translator Demo. In this application we did not
find any difficulties on accessing it. However, we had noticed that the number of
words that it is possible to write and therefore being translated is very limited, as
well as the number of languages. We also observed that it is not possible to neither
record the text nor write big texts. During our research on the newest models of the SmartPen, namely the Echo version, it has much more possibilities in this type of
application.
At last, we also tested the Livescribe Desktop application. In our experiments, we
observed that this application is only useful to the smartpen’s owner or for who has
their personal data, because it is not possible to perform any interaction with the
computer; the application always requests for login authentication. In general, when we use this smartpen for the first time, the navigation menu can
be a little confusing. However, after some exploration and more usage of the
menus, the user’s options becomes simpler and more understandable, leading him
to make less mistakes and get less confused.
Once we had concluded the verification of the Smartpen features, we can affirm
that this pen has been improved over the years and becoming an extremely useful
device to all kind of people, but particularly in the field of the education. This pen
can be used in everyone’s day-to-day, or even to professional purposes, such as conferences or lectures.
After this study had been done, we believe that the Smartpen that was used in our

already are more evolved because they contain much more complex and even more useful features, which in turn makes people want to buy it. Even though the
cost is a little high, we think that it does not represent a limitation to acquire the
Smartpen. This new pen will be a tool with a constant evolution because it will
have more and more beneficial features to the user.
The objectives of this work are mainly focused on making a thorough study about
the Smartpen, specifically about its operations, features and applications.
It will also be done a demonstration of the functionality of the pen, from where we
will take some conclusions. Finally, we will make some improvement
suggestions based on the demonstration made, as well presenting new useful
features.

Objectives
The Smartpen
allows the user to change the instrument and the rhythm, respectively, by simply
tapping on them.
Augmented Reality and the Smartpen
The Augmented Reality is an environment that evolves either the virtual reality as
the elements of the real world, creating a mixed environment in real time. The most remarkable distinction made between the AR and UC is that the second
does not focus on the disappearing of the conscientious and intentional interaction,
as much as the AR focuses. The UC systems, like the diffused computational
devices, keep the concept of the interaction very explicit and intentional, which is
involved in a typical work of AR, as Ronald Azuma’s.
The Smartpen is a real object which we can interact computationally, becoming an Augmented Reality tool. This smart pen, besides writing like a regular pen,
presents some technological features that allow the user to play a piano with it and
with a draw on his dot paper notebook
New Features
An infrared pen is actually a very useful tool that allows a computerized interaction
in an interactive whiteboard.
The utilization of the Smartpen on interactive whiteboards would be a good feature
to be implemented on it, because these two objects, when together, could form a much more powerful device on educational environments. Therefore, the tip of the
Smartpen should be adapted with an infrared LED to be used as an infrared pen in
an interactive whiteboard.
As the new versions of the Smartpen already have a Bluetooth connection, it is not
necessary a receiving device besides the computer. Therefore, the Smartpen itself
would be capable of sending the data to the computer via Bluetooth, which in turn would be projected on the whiteboard.
have more and more beneficial features to the user.

The speed and performance of my home network was not affected. The only visitor on my hotspot indicated was me, so I decided to test the performance of the network having two laptops online in the home network and one in the fon; The bandwidth for both was the same 54mb, the speed and response from the web browsing was equal for both networks, so even if there is a significant amount of people connected in the hotspot the home network would not be affected.
In my way to Garajau I had my smartphone detecting WiFi signals and for my surprise I found 11 free fon hotspots between Caniço centro and Garajau (Figure 2). I attribute this to the difficulty that is to set the right localization for the hotspots or is also another possibility that the new Zon routers have the fon setting activated without people taking knowledge of this.
WHAT IS FON?
Fon was founded by Martin Varsavsky, with the goal of free, ubiquitous WiFi for everyone.
Today, Fon is the largest WiFi community in the world, with over three million Fon WiFi spots and over five million users.
The idea of Fon is that every person that have a WiFi connection in their home can become a hotspot for others to use. The members of Fon agree to share their WiFi at home and get free roaming at all the Fon spots worldwide in return.
Besides the free WiFi connection all over the world that the Fon community offers, it also offers ways to make profit with the hotspot; who is registered as a bill receives 50% of revenue for each alien member that decides to buy a pass and access to his hotspot. This is a good way to attract members and small business.
Figure 2 - rout with hotspots discovered
CONCLUSION
Fon is the only initiative that based their idea in a community, so their growth only depends of people interest. If people wanted connectivity everywhere they can buy one of the fon routers call “fonera” or if they are lucky their telecommunication company had a partnership with fon and their router already allows to become a fon hotspot.
Fon provides access to the internet without almost any cost and if members choose to receive part of the profit made with his hotspot it can make a significant amount of money (it needs to be in consideration the localization of the hotspot); that’s why their service also attract coffee shops, restaurants and private parks because is a win-win situation.
I can say that Fon is the only company that is really making internet connection ubiquitous. In the big cities we can found innumerous fon hotspots and even in Madeira a small island we now find a significant amount of fon spots.
Various studies confirm paper has inherent advantage over
electronic platforms in many forms of activities. Paper sheets can be
bent, folded, shredded, recycled, stapled and written on at a very low
cost and without the need for software upgrades or everlasting
battery supplies. Despite the prediction of a paperless future, paper
documents are still widely used in our everyday activities. Paper is
not dead [2].
Direct Latitude/Longitude Identification of Paper
Maps Using a Camera Phone This system adopts a new technique to embed geographical
coordinates into paper maps and directly identify them using a
camera phone, which is particularly useful for travelling. Through a
simple photo from the camera, the system can easily trace back the
map coordinates for that region, which can be exchanged with GPS
devices to find the way around. This provides real-time recognition
via print maps on most commercial mobile phones.
.
- A Paper Interface for Code Exploration This augmented reality system is designed to offer active exploration
tools for programmers confronted with the problem of getting familiar
with a large codebase, methods, classes and relations. In a typical
scenario, new programmers coming to an institution have to learn
about a project in order to start their own contribution.
With this application programmers can easily browse through
classes, edit methods trough simple steps, and preview their
changes on a large class diagram display. One of the main
advantages of this application is the quick and intuitive code editing;
the user only needs to select a class to edit its contents, and by
selecting a method or variable will automatically highlight it. He can
thereafter apply the changes he wants in the computer and update
them in less than a second.
Figure 2- Three classes are used for this illustration. The paper command show source is applied on MyClass, and
projects its result in red. The paper command print group has been used to produce the paper object representing
the three classes circled by the yellow box. The paper command show occurrences is applied on one of the
methods of MyClass, and the resulting set of class is restricted to the previously mentioned group. The results are
projected in blue.
The development of interactive paper solutions has become a very
active research area. While different interactive paper frameworks
support the application development, the question is whether these
frameworks are missing a common abstraction layer. It might be the
right time to reflect and share some wisdom. The definition of
common data formats and design guidelines could be a first step
towards real cross-application and cross-framework interoperability.
There is also the need to debate whether these applications, despise
being useful in practice, can be an economically viable source of
investment.
There can also be many technical constrains in this kind of
development, such as device independence (so that different devices
can communicate with each other in an optimal way), digital ink
abstraction and application deployment.
One of the most challenging obstacles to overcome would also be
the need of precise cross-application operability, as well as more
advanced data recognition, data processing and rendering algorithms
that fit a useable device on our everyday use. Afteral, that is the main
premise of Weiser’s vision.

There are a variety of interactive paper applications covering different
domains. In addition to different hardware solutions, there exist a
number of software frameworks for the digital pen and paper
technology. In the remaining part of this paper, we would like to
outline some future technical as well as non-technical challenges to
stimulate a discussion between interactive paper application and
framework developers [4] as well as which areas of knowledge can
take use of this technology.
- Searchable Books
Paper books remain popular, as many readers prefer the reading
experience that paper books provide, which digital interfaces
cannot. In this example, the goal is to improve users’ reading
experience by enhancing books with digital functionalities.
This application can be used on a mobile phone to scan trough a
book with a camera, recognize the information, and ultimately be
able to search any contents within the text. In essence, we are
virtualizing books, keeping both the physical and virtual paper
advantages.
- TheNeverendingStorytellingMachine
A conceptual system that would augment storybooks with 3D
and anaglyph content that is oriented according to the reader’s
posture and registered right on the paper. The system allows
direct finger interaction with the projected graphics to create an
immersive and entertaining user experience during reading. This
system has been used with a great outcome in teaching lower
aged students.
Engaged by both physical and digital dimensions, users are no
longer constrained by traditional story writing means, but instead,
are encouraged to explore stories as multisensorial experiences .

The main goal of this research is to understand the real application
uses of paper computing and the advantages that we can acquire by
using it on some tasks mainly on enterprises, but also in some
personal applications. We will present some examples of the utility of
this technology and try to understand what kind of future it will have.
In this work, we will introduce the main features of a paper computing
system, their advantages and how they can be used to improve our
everyday activities. We will understand the main advantages of
paper when compared to digital systems and analyze some
examples of paper computing systems. The final part of our work is
about future speculations in this area and how it has evolved during
the last few years. We will conclude that a vision of a paperless world
is far from true and that paper based systems can and will be a part
of our future.
The use of wireless networks is the technology most commonly used nowadays.
Every home, professional environment or university has it, sharing information
through cables is becoming part of the past. The use of wifi technologies can be
unsecure because of the lack of physical security and with this new methodologies
like wardriving were invented. This methodology gives the ability to find wireless
networks. Although not legal, many people use it because of the benefits, a good
database of access points can save you a lot of money since you do not need to
pay to access the internet. Over time it became increasingly easy to do it, many
applications are available for all kind of Operating Systems.
MethodologyThe first step was to search for applications that could do this kind of work, we found some good applications, but they needed external GPS support. We started to test KisMac
and NetStumbler, both gave us a good feedback on Wi-Fi networks like the SSID (Service Set Identifier), channel, gain and security but unfortunately GPS functionality did not
work. Since the collected information did not have GPS support it became difficult to organize it. Then we tried the WarDrive application for Android, but like the other
applications, we started to have problems and the collected data was incomplete, due to many problems with the GPS on this application. We did not give up, many other
testing were done, since the results were not what we expect, we tried another application named G-Mon. After analyzing the following applications, NetStumbler, KisMac,
WarDrive, WiGLE and G-Mon we concluded that the one with better results was G-Mon 2.x.
G-Mon is a powerful WarDriving scanner and GSM/UMTS net monitor and dive test tool which can be used on Android platform. It scans for all Wi-Fi networks in range and
saves the data with GPS coordinates into a file on a SD card. A kml file for Google Earth can be also created. It shows the encryption, channel and signal strength.
G-Mon gives the ability to collect and map all detected Wi-Fi access points. It is also a 2G/3G net monitor and field test drive tool for radio planning engineers. Needs enabled
GPS for correct position in map.
In this section we will make a brief comparison between the four wardriving
application tested, NetStumbler, KisMac, WarDrive and G-Mon.
NetStumbler is an active wireless network detection application that does not
passively listen for or receive packets. Its interface also provides filtering and
analysis tools.
KisMAC is a passive network detector on supported cards (e.g. Apple’s AirPort),
packet sniffer and an intrusion detector system.
After using WarDrive service we’ve noticed that the GPS locator showed up for two
seconds and disappeared again. Location gets fixed if we start another GPS
location fixing application (i.e. GPS status) that records WarDrive locations
properly. After exporting the kml file, only two locations were mapped.
WiGLE (Wireless Geographic Logging Engine) is a website for collecting
information about the different wireless hotspots around the world. Anyone can use
it, and share a local on WiGLE’s website, so anyone can see a global map with all
the access points available.
Finally, G-Mon application was the one that gave us better results. It is an easy to
use application because we just need a mobile phone with embedded GPS and
wireless internet. After wardriving, a kml file with the daily export is saved on SD
card. That kml file can be opened in Google Earth, and lets us see all the access
points scanned. Note that we made three approaches, within approximately one
month each, and different samples were collected.
WarDriving is a technique that can be very valuable to the technology community,
assuming that it is used with the intent that it was planned on.
WarDriving can be both fun and informative and can be done by anyone, it does
not have to be done only by computer professionals.
The easy use of this technology has made that people take care about their
wireless network configurations.
Wardrivers can help anyone to set their networks more secure. Many of the
insecure networks can illegally be exploited by crackers and attackers.
We have to adapt to new technologies, wardriving is not going away, we have to
learn and improve security. After reviewing several applications we found that
wardriving is very easy to do. With this project we acquire knowledge in security
and wifi networks. The security of networks can be improved, many alternatives
