Designing usable mobile interfaces for spatial data
2010 - 2011This
dissertation
deals
mainly
with
the
discipline
of
Human-‐Computer
Interaction
(HCI),
with
particular
attention
on
the
role
that
it
plays
in
the
domain
of
modern
mobile
devices.
Mobile
devices
today
offer
a
crucial
support
to
a
plethora
of
daily
activities
for
nearly
everyone.
Ranging
from
checking
business
mails
while
traveling,
to
accessing
social
networks
while
in
a
mall,
to
carrying
out
business
transactions
while
out
of
office,
to
using
all
kinds
of
online
public
services,
mobile
devices
play
the
important
role
to
connect
people
while
physically
apart.
Modern
mobile
interfaces
are
therefore
expected
to
improve
the
user's
interaction
experience
with
the
surrounding
environment
and
offer
different
adaptive
views
of
the
real
world.
The
goal
of
this
thesis
is
to
enhance
the
usability
of
mobile
interfaces
for
spatial
data.
Spatial
data
are
particular
data
in
which
the
spatial
component
plays
an
important
role
in
clarifying
the
meaning
of
the
data
themselves.
Nowadays,
this
kind
of
data
is
totally
widespread
in
mobile
applications.
Spatial
data
are
present
in
games,
map
applications,
mobile
community
applications
and
office
automations.
In
order
to
enhance
the
usability
of
spatial
data
interfaces,
my
research
investigates
on
two
major
issues:
1. Enhancing
the
visualization
of
spatial
data
on
small
screens
2. Enhancing
the
text-‐input
methods
I
selected
the
Design Science Research approach
to
investigate
the
above
research
questions.
The
idea
underling
this
approach
is
“you
build artifact to learn from it”, in
other
words
researchers
clarify
what
is
new
in
their
design.
The
new
knowledge
carried
out
from
the
artifact
will
be
presented
in
form
of
interaction
design
patterns
in
order
to
support
developers
in
dealing
with
issues
of
mobile
interfaces.
The
thesis
is
organized
as
follows.
Initially
I
present
the
broader
context,
the
research
questions
and
the
approaches
I
used
to
investigate
them.
Then
the
results
are
split
into
two
main
parts.
In
the
first
part
I
present
the
visualization
technique
called
Framy.
The
technique
is
designed
to
support
users
in
visualizing
geographical
data
on
mobile
map
applications.
I
also
introduce
a
multimodal
extension
of
Framy
obtained
by
adding
sounds
and
vibrations.
After
that
I
present
the
process
that
turned
the
multimodal
interface
into
a
means
to
allow
visually
impaired
users
to
interact
with
Framy.
Some
projects
involving
the
design
principles
of
Framy
are
shown
in
order
to
demonstrate
the
adaptability
of
the
technique
in
different
contexts.
The
second
part
concerns
the
issue
related
to
text-‐input
methods.
In
particular
I
focus
on
the
work
done
in
the
area
of
virtual
keyboards
for
mobile
devices.
A
new
kind
of
virtual
keyboard
called
TaS
provides
users
with
an
input
system
more
efficient
and
effective
than
the
traditional
QWERTY
keyboard.
Finally,
in
the
last
chapter,
the
knowledge
acquired
is
formalized
in
form
of
interaction
design
patterns. [edited by author]X n.s
Redesenho da interface de utilizador da aplicação móvel Us'Em
Mestrado em Comunicação MultimédiaThe research presented here aims to design a feasible and adequate mobile application (app) user interface. This mobile app is part of Us'em system, designed to promote self-rehabilitation after stroke. The system is based on wearable, mobile and tracking sensors-based technology. The app works as a feedback tool, communicating Us’em system users about the frequency of their upper limb moves and about their recovery process. The mobile app aims increasing patient’s motivation in using their arm-hand through the day and improving their rehabilitation through self-training at home with continuous feedback. The design of its user interface is of great relevance, because it
determines if post stoke patients can use Us’em system. The empirical part begins with interviews, questionnaires and observation of
post stroke patients and physical therapists from Portugal and the Netherlands. It provides a better understanding of post stroke rehabilitation process and stroke victims’ characteristics and requirements regarding rehabilitation and mobile devices interaction.
The gathered information contributed to the development of a prototype that materializes the defined Us’em app. The prototyping process ran through iterative cycles of design, implementation and evaluation to ascertain the adequacy of Us’em app user interface.
The final prototype is the final product of this research project and it was evaluated through usability tests with post stroke patients from both countries aforementioned. Tests to the final prototype show it may be difficult to design a unique solution
for all the users due to the wide range of their requirements. However, the core requirements of Us'em mobile app is simplicity: the number of user interface elements, the amount of information and the complexity of iteractions and functionalities of this app should be the lowest as possible. The research also allows to conclude that the user interface designed meets most of user’s requirements and it has a significant impact on the motivation of post stroke patients in moving their impaired arm-hand autonomously.O trabalho de investigação aqui apresentado objetiva o desenvolvimento de uma viável e adequada interface de utilizador de uma aplicação móvel (app). Esta app é um dos componentes do sistema Us’em, desenvolvido para promover a auto reabilitação após acidentes vasculares cerebrais (AVC). O sistema é baseado em tecnologia vestível, móvel e de monitorização através de sensores.
A app funciona como uma ferramenta de feedback, informando os utilizadores do sistema Us’em sobre a frequência dos movimentos dos seus membros superiores e sobre o seu processo de recuperação. A app objetiva aumentar a motivação dos pacientes em usar o seu braço ou mão debilitado ao longo do dia e, assim, promover a sua reabilitação através do treino autónomo em casa com feedback contínuo. O desenvolvimento da interface de utilizador é de grande relevância, pois determina se pacientes vítimas de AVC conseguem utilizar o sistema Us’em. O estudo empírico parte da realização de entrevistas, questionários e observação de pacientes vítimas de AVC e fisioterapeutas Portugueses e Holandeses. Este estudo permite uma melhor compreensão do processo de reabilitação e das características e requisitos de vítimas de AVC no que respeita à reabilitação e à interação com dispositivos móveis. A informação recolhida contribuiu para o desenvolvimento de um protótipo que concretizasse a app Us’em definida. O processo de prototipagem ocorreu ao longo de ciclos iterativos de desenvolvimento, implementação e teste de forma a verificar a adequação da interface de utilizador da app Us’em.
O protótipo final é o produto final deste projeto de investigação e foi testado através de testes de usabilidade com pacientes vítimas de AVC de ambos os países referidos anteriormente. Os testes ao protótipo final revelam que poderá ser difícil desenvolver uma
solução única para todos os utilizadores devido ao conjunto vasto dos seus requisitos. No entanto, o requisito chave da app Us’em é simplicidade: o número de elementos da interface de utilizador, a quantidade de informação e a complexidade das interações e funcionalidades da app deve ser o mais reduzido possível. Esta investigação também permite concluir que a interface de utilizador desenvolvida satisfaz a maior parte dos requisitos dos utilizadores e tem um impacto significativo na motivação de pacientes vítimas de AVC em movimentar o seu braço ou mão desabilitada de forma autónoma

Visual search and VDUS
This wide-ranging study explored various parameters of visual search in relation to computer screen displays. Its ultimate goal was to help identify factors which could result in improvements in commercially available displays within the 'real world’. Those improvements are generally reflected in suggestions for enhancing efficiency of locatabolity of information through an acknowledgement of the visual and cognitive factors involved. The thesis commenced by introducing an ergonomics approach to the presentation of information on VDUs. Memory load and attention were discussed. In the second chapter, literature on general and theoretical aspects of visual search (with particular regard for VDUs) was reviewed. As an experimental starting point, three studies were conducted involving locating a target within arrays of varying configurations. A model concerning visual lobes was proposed. Two text-editing studies were then detailed showing superior user performances where conspicuity and the potential for peripheral vision are enhanced. Relevant eye movement data was combined with a keystroke analysis derived from an automated protocol analyser. Results of a further search task showed icons to be more quickly located within an array than textual material. Precise scan paths were then recorded and analyses suggested greater systematicity of search strategies for complex items. This led on to a relatively 'pure' search study involving materials of varying spatial frequencies. Results were discussed in terms of verbal material generally being of higher spatial frequencies and how the ease of resolution and greater cues available in peripheral vision can result in items being accessed more directly. In the final (relatively applied) study, differences in eye movement indices were found across various fonts used. One main conclusion was that eye movement monitoring was a valuable technique within the visual search/VDU research area in illuminating precise details of performance which otherwise, at best, could only be inferred
Recent Application in Biometrics
In the recent years, a number of recognition and authentication systems based on biometric measurements have been proposed. Algorithms and sensors have been developed to acquire and process many different biometric traits. Moreover, the biometric technology is being used in novel ways, with potential commercial and practical implications to our daily activities. The key objective of the book is to provide a collection of comprehensive references on some recent theoretical development as well as novel applications in biometrics. The topics covered in this book reflect well both aspects of development. They include biometric sample quality, privacy preserving and cancellable biometrics, contactless biometrics, novel and unconventional biometrics, and the technical challenges in implementing the technology in portable devices. The book consists of 15 chapters. It is divided into four sections, namely, biometric applications on mobile platforms, cancelable biometrics, biometric encryption, and other applications. The book was reviewed by editors Dr. Jucheng Yang and Dr. Norman Poh. We deeply appreciate the efforts of our guest editors: Dr. Girija Chetty, Dr. Loris Nanni, Dr. Jianjiang Feng, Dr. Dongsun Park and Dr. Sook Yoon, as well as a number of anonymous reviewers
