Summary: Ubiquitous projection or "display everywhere" is a popular paradigm,
according to which regular rooms are augmented with projected digital content
in order to create immersive interactive environments. In this work, we revisit
this concept, where instead of considering every physical surface and object as
a display, we seek to determine areas that are suitable for the projection and
interaction with digital information. After determining a set of requirements
that such surfaces need to fulfil, we describe a novel computer vision-based
technique to automatically detect rectangular surface regions that are deemed
adequate for projection and mark those areas as available placeholders for
users to use as "clean" displays. As a proof of concept, we show how content
can be adaptively laid out in those placeholders using a simple tablet UI.

Summary: Whether in the developed or developing countries, aging of population has
been a common global trend. With the development of the communication
technology and the Internet era of prosperity, the elderly people also
inevitably need to use modern communication products such as mobile phone so
that they could keep contact with their family, children, the outside world,
including quick call in case of an emergency etc. But the physiology and
psychology of the elderly are very different from the young people, which
mainly is reflected in the degradation of vision, hearing, touch, reaction
ability, hand strength, text and graphics memory ability and so on. Thus when
the elderly people are using the mobile phone there are a lot of inconvenience
and special requirements by them and the user experience is also far different
form the other age groups. Therefore, in the design of the mobile phone for the
older age groups whether the appearance design or the interaction design should
reflect on our care for this special group, to improve the usability of the
product, to bring convenience for them. This paper firstly studies the
physiological and psychological characteristics of the elderly. Then it
analyses the behavior characteristics of the elderly in the use of mobile phone
and the user experience. Moreover some principles and methods of interaction
design for the elderly mo-bile phone are presented in this essay; Additionally
through several practical cases of the mobile phone design for the elderly in
China and by using the research method such as the user behavior analysis, user
survey, Analysis of the availability of products, product evaluation, this
paper will analyze and summarize the shortcomings of the current mo-bile phone
for the elderly in interaction design. Finally this paper will not only point
out the direction of improvement for the elderly mobile interaction design but
also provide some useful suggestions and enlightenment for the elderly mobile
phone design in the future.

Summary: Understanding nonverbal behaviors in human machine interaction is a complex
and challenge task. One of the key aspects is to recognize human emotion states
accurately. This paper presents our effort to the Audio/Visual Emotion
Challenge (AVEC'14), whose goal is to predict the continuous values of the
emotion dimensions arousal, valence and dominance at each moment in time. The
proposed method utilizes deep belief network based models to recognize emotion
states from audio and visual modalities. Firstly, we employ temporal pooling
functions in the deep neutral network to encode dynamic information in the
features, which achieves the first time scale temporal modeling. Secondly, we
combine the predicted results from different modalities and emotion temporal
context information simultaneously. The proposed multimodal-temporal fusion
achieves temporal modeling for the emotion states in the second time scale.
Experiments results show the efficiency of each key point of the proposed
method and competitive results are obtained.

Summary: This paper addresses the problem of producing very compact representation of
a face image for large-scale face search and analysis tasks. In tradition, the
compactness of face representation is achieved by a dimension reduction step
after representation extraction. However, the dimension reduction usually
degrades the discriminative ability of the original representation drastically.
In this paper, we present a deep learning framework which optimizes the
compactness and discriminative ability jointly. The learnt representation can
be as compact as 32 bit (same as the int32) and still produce highly
discriminative performance (91.4% on LFW benchmark). Based on the extreme
compactness, we show that traditional face analysis tasks (e.g. gender
analysis) can be effectively solved by a Look-Up-Table approach given a
large-scale face data set.

Summary: The paper describes the way expertise and field-knowledge can impact the
transfer of graphical intentions during architectural cooperative design. The
analysis of 28 controlled experiments reveals what matters in transmitting
architectural intents and more specifically underlines how novices' intuitive,
deductive processes based on previous and embodied experiences interestingly
complement experts' knowledge of the architectural field and its semantics. The
results directly inform how we, as researchers, designers and engineers, should
take advantage of both novices' and experts' strategies to develop tools,
methods or interfaces to support next generation cooperative design.

Summary: With the advance of pedagogical materials from printed textbooks to
e-textbooks, the methods of note-taking should also be improved. For e-Learning
with 3D interactive curricular contents, an ideal note-taking approach should
be intuitive and tightly coupled with the curricular contents. Particularly,
augmented reality (AR) technology is capable of displaying virtual contents in
real-life images. Combining head-mounted displays with cameras and wearable
computers, AR provides chances and challenges to improve note-taking for
situated learning in contextual surroundings. We propose an AR-based
note-taking system tailored for 3D curricular contents. A learner can take
notes on a physical tabletop by finger writing, manipulate curricular contents
using hand gestures and embed the complete notes in the corresponding contents
in a 3D space. An analytic hierarchy process demonstrates the strengths and
weaknesses of the proposed 3D note-taking system. Especially, note-taking using
finger writing and hand gestures with 3D maneuver is better than other
alternatives in terms of relevance, usefulness, intuition and novelty.

Summary: We study the problem of recommending scientific articles to users in an
online community and present a novel matrix factorization model, the topic
regression Matrix Factorization (tr-MF), to solve the problem. The main idea of
tr-MF lies in extending the matrix factorization with a probabilistic topic
modeling. Instead of regularizing item factors through the probabilistic topic
modeling as in the framework of the CTR model, tr-MF introduces a regression
model to regularize user factors through the probabilistic topic modeling under
the basic hypothesis that users share the similar preferences if they rate
similar sets of items. Consequently, tr-MF provides interpretable latent
factors for users and items, and makes accurate predictions for community
users. Specifically, it is effective in making predictions for users with only
few ratings or even no ratings, and supports tasks that are specific to a
certain field, neither of which is addressed in the existing literature.
Further, we demonstrate the efficacy of tr-MF on a large subset of the data
from CiteULike, a bibliography sharing service dataset. The proposed model
outperforms the state-of-the-art matrix factorization models with a significant
margin.

Summary: With the rapid development of social networks, tagging has become an
important means responsible for such rapid development. A robust tagging method
must have the capability to meet the two challenging requirements: limited
labeled training samples and noisy labeled training samples. In this paper, we
investigate this challenging problem of learning with limited and noisy tagging
and propose a discriminative model, called SpSVM-MC, that exploits both labeled
and unlabeled data through a semi-parametric regularization and takes advantage
of the multi-label constraints into the optimization. While SpSVM-MC is a
general method for learning with limited and noisy tagging, in the evaluations
we focus on the specific application of noisy image tagging with limited
labeled training samples on a benchmark dataset. Theoretical analysis and
extensive evaluations in comparison with state-of-the-art literature
demonstrate that SpSVM-MC outstands with a superior performance.

Summary: The study aims to explore the roles of anxiety and motivation in foreign
language learning. A total of 141 freshmen at a private university in south
Taiwan served as subjects. The research instrument includes the Foreign
Language Classroom Anxiety Scale (FLCAS) (Horwitz, Horwitz, & Cope, 1986),
Motivation/attitude about foreign language learning (Gardner, 1985), as well as
two English scores of Taiwan College Entrance Exam (CEE) and National English
Test of Proficiency All on the Web (NETPAW). All available data were processed
by SPSS 16 (Statistical Package of Social Science). Findings show the two
English scores of CEE and NETPAW, as well as motivation, attitude and
motivational intensity are strongly correlated to one another. In addition,
motivational intensity is related to score of NETPAW, but anxiety is the best
predictor of students' score of NETPAW positively. It's expected that the
findings can provide teachers with some hints for more effective foreign
language teaching and learning by being aware of students' individual
differences.

Summary: Discretization is a standard technique used in click-based graphical
passwords for tolerating input variance so that approximately correct passwords
are accepted by the system. In this paper, we show for the first time that two
representative discretization schemes leak a significant amount of password
information, undermining the security of such graphical passwords. We exploit
such information leakage for successful dictionary attacks on Persuasive Cued
Click Points (PCCP), which is to date the most secure click-based graphical
password scheme and was considered to be resistant to such attacks. In our
experiments, our purely automated attack successfully guessed 69.2% of the
passwords when Centered Discretization was used to implement PCCP, and 39.4% of
the passwords when Robust Discretization was used. Each attack dictionary we
used was of approximately 235 entries, whereas the full password space was of
243 entries. For Centered Discretization, our attack still successfully guessed
50% of the passwords when the dictionary size was reduced to approximately 230
entries. Our attack is also applicable to common implementations of other
click-based graphical password systems such as PassPoints and Cued Click Points
-- both have been extensively studied in the research communities.

Summary: In this paper we study the problem of mining noisy tagging. Most of the
existing discriminative classification methods to this problem only consider
one tag at a time as the classification target, and completely ignore the rest
of the given tags at the same time. In this paper we argue that all the given
multiple tags can be utilized simultaneously as an additional feature and the
information contained in the multi-label space can be taken advantage of to
improve the performance of the classification. We first propose a novel
distance measure to compute the distance between instances in the multi-label
space. Then we propose several novel methods to incorporate the information of
the multi-label space into the discriminative classification methods in one
view learning or in two views learning to solve a general multi-label
classification problem and to mitigate the influence of the noise in the
classification. We apply the proposed solutions to the problem with a more
specific context -- noisy image annotation, and evaluate the proposed methods
on a standard dataset from the related literature. Experiments show that they
are superior to the peer methods in the existing literature on solving the
problem of mining noisy tagging.

Summary: Millions of posts are being generated in real-time by users in social
networking services, such as Twitter. However, a considerable number of those
posts are mundane posts that are of interest to the authors and possibly their
friends only. This paper investigates the problem of automatically discovering
valuable posts that may be of potential interest to a wider audience.
Specifically, we model the structure of Twitter as a graph consisting of users
and posts as nodes and retweet relations between the nodes as edges. We propose
a variant of the HITS algorithm for producing a static ranking of posts.
Experimental results on real world data demonstrate that our method can achieve
better performance than several baseline methods.

toolkits. The implementation of such rich graphical components require a high
programming effort that GUI toolkits do not alleviate. In this paper, we
propose the Loa framework that allows both the specification of rich graphical
components and their integration within running interactive applications. We
illustrate the specification and integration with the Loa framework as part of
a global process for the design of interactive systems.

Summary: Facial expression provides an important clue for teachers to know the
learning status of students. Thus, vision-based expression analysis is valuable
not only in Human-Computer Interface but also in e-Learning. We propose a
computer vision system to automatically analyze learners' video to recognize
nonverbal facial expressions to discover learning status of students in
distance education. In the first stage, Adaboost classifiers are applied to
extract candidates of facial parts. Then spatial relationships are utilized to
determine the best combination of facial features to form a feature vector. In
the second stage, each feature vector sequence is trained and recognized as a
specific emotional expression using Hidden Markov Model (HMM). The estimated
probabilities of six expressions are combined into an expression vector. The
last stage is to analyze the expression vector sequence to figure out the
learning situation of the student. Gaussian Mixture Model (GMM) is applied to
evaluate three learning scores (Understanding, Interaction, and Consciousness)
that are integrated into a status vector. Each evaluated status vector reflects
the learning status of a student and is helpful to not only teachers but also
students for improving teaching and learning.

Summary: Dandelion is a wiki-based tool that supports coordinated, collaborative
authoring. In this paper, we present an ex-tended version of Dandelion, which
provides an email inter-face for users to accomplish their tasks by email in a
coordinated, collaborative authoring process. Specifically, Dandelion employs a
semi-structured, template-based approach that allows users to use templates to
specify their requests in email. These emailed requests can be interpreted by
Dandelion and are then used to automatically drive the collaboration flow. As
part of its actions, Dandelion automatically creates a wiki page and
dynamically updates it to record co-authoring tasks and collate co-authored
content. As a result, users can use their familiar tool (email) to accomplish
their tasks in a co-authoring process, while leveraging a wiki for additional
benefits (e.g., obtaining collaboration awareness and formatting the text). Our
preliminary study with two groups of users shows the usefulness of both
Dandelion email and wiki features and their impact on collaboration
effectiveness.

interactions when or after raindrops hitting on tree branches can be well
simulated using a new efficient technique specially designed for liquid motion
on non-rigid objects with hydrophilic surfaces. Experimental results indicate
that our approach can be used to simulate the interactions between tree
branches and raindrops efficiently and realistically.

Summary: Natural head motion is an indispensable part of realistic facial animation.
This paper presents a novel approach to synthesize natural head motion
automatically based on grammatical and prosodic features, which are extracted
by the text analysis part of a Chinese Text-to-Speech (TTS) system. A two-layer
clustering method is proposed to determine elementary head motion patterns from
a multimodal database which covers six emotional states. The mapping problem
between textual information and elementary head motion patterns is modeled by
Classification and Regression Trees (CART). With the emotional state specified
by users, results from text analysis are utilized to drive corresponding CART
model to create emotional head motion sequence. Then, the generated sequence is
interpolated by spine and used to drive a Chinese text-driven avatar. The
comparison experiment indicates that this approach provides a better head
motion and an engaging human-computer comparing to random or none head motion.

Summary: The goal of predicting query potential for personalization is to determine
which queries can benefit from personalization. In this paper, we investigate
which kind of strategy is better for this task: classification or regression.
We quantify the potential benefits of personalizing search results using two
implicit click-based measures: Click entropy and Potential@N. Meanwhile,
queries are characterized by query features and history features. Then we build
C-SVM classification model and epsilon-SVM regression model respectively
according to these two measures. The experimental results show that the
classification model is a better choice for predicting query potential for
personalization.

Summary: Logistic average misclassification percentage (lam%) is a key measure for
the spam filtering performance. This paper demonstrates that a spam filter can
achieve a perfect 0.00% in lam%, the minimal value in theory, by simply setting
a biased threshold during the classifier modeling. At the same time, the
overall classification performance reaches only a low accuracy. The result
suggests that the role of lam% for spam filtering evaluation should be
re-examined.

Summary: In this paper, we explored the feasibility of analysing gait patterns during
the Short Physical Performance Battery test by using an accelerometer to record
the movement of the subject. 12 subjects with Complex Regional Pain Syndrome
(CRPS) and 10 control subjects were recruited in this study. 21 gait features
including temporal, frequency, regularity and symmetric information were
extracted from each recording. The differences of each feature value on control
subjects and patient subjects were assessed and compared. Features were
selected based on the signal to noise ratio (SNR) ranking. Multilayer
perceptron neural-networks were employed to differentiate between the normal
and abnormal gait patterns. The result shows when using five features the best
classification accuracy (97.5%) was achieved. It is feasible to discriminate
the patients with CRPS from the control subjects using a small set of gait
features extracted from walking acceleration data recorded during the SPPB
test.

Summary: Falconer is a semantic Web search engine enhanced SIOC
(Semantically-Interlinked Online Communities) application, which is designed to
demonstrate the ability of accelerating the creation and reuse process of
semantic Web data with easy-to-use user interfaces. In this process, semantic
Web search engines feed existing semantic data into the SIOC framework, where
new semantic data are composed by the community and indexed again by those
search engines. Compared to existing social (semantic) Web applications,
Falconer inherently conforms to SIOC specification. It provides semantic search
engine based user registration suggestion, friends auto-discovery, and semantic
annotation for forum post content. Another distinctive feature is that it
enables users to subscribe any resource having a URI as the topic they are
interested in. The relationships among users, topics, and posts are further
visualized for analyzing the topic trends in the community. As all semantic
data are formatted in RDF and RDFa, they can be queried with SPARQL query
language.

Summary: Dandelion is a tool that extends wikis to support coordinated, collaborative
authoring using a tag-based approach. Specifically, users can insert tags in a
wiki page to specify various co-authoring tasks. These tags can then be
executed to help drive and manage the collaboration workflow, and provide
content-centric collaboration awareness for all the co-authors. Four successful
pilot deployments and positive user feedback show the practical value of
Dandelion, especially its value in supporting a structured, collaborative
authoring process often seen in business settings.
