TRANSCRIPT
CENTRE D’ALT RENDIMENT (CAR) SMART VENUE
CAR is a high performance training centre for elite athletes providing every-
thing necessary for training and competition at the highest level. Technology
is at the heart of CAR’s activities and the use of advanced human tracking
and monitoring systems provide coaches and athletes with the essential data
to push the human body to ever greater achievements.
ENHANCING TRAINING EXPERIENCE AND PERFORMANCE
High performance training is a complex endeavor requiring continuous sup-
port from specialists responsible for analysis of multi-factor data. Coaches
and doctors need accurate measurements in order to offer the correct feed-
back for performance improvements and to avoiding injuries. Feedback must
be timely and often instantaneous to increase the efficiency of training ses-
sions. FMI technologies have the potential to achieve these goals by moving
current laboratory procedures to integral elements of day to day training prac-
tices.
BENEFITS OF TECHNOLOGY TRIALS AT CAR
CAR can help developers understand how new tech-
nologies can track and analyse human activities espe-
cially in the domain of high performance sports. Tech-
nologies trialed at CAR engage athletes, coaches and sports scientists direct-
ly in co-creation and evaluation. CAR enables tests with small groups of ath-
letes and scientific experts. With access to training areas and network/cloud
infrastructure available on site CAR is a unique opportunity.
The Centre d’alt Rendiment is an EX-
PERIMEDIA smart venue offering live
events, communities, and infrastruc-
ture for research and testing of innova-
tive technologies supporting new forms
of social interaction and experience.

interactive media for
collaborative sports training
KEY FEATURES:
MOTIVATION
Technology is an essential element of high performance sport
which helps coaches and sports scientists design and exe-
cute training plans for elite athletes. CONFetti focused on
how to support participation of remote coaches in gymnastics
training. Can the availability of coaches be increased by
holding training sessions even when they are not present at
the venue? Does access to additional motion tracking and
sensor data concerning the athletes' performance improve
coaching decisions? Is the transfer of knowledge and instruc-
tions more efficient with the use of archival footage and 3D
model teaching aids? Do new technologies like augmented
reality or stereoscopy appeal to young athletes and make the
sessions more interesting and, in turn, more beneficial?
These are just some of the issues explored by CONFetti.
TECHNICAL INNOVATION
The technologies used included HD videoconferencing, stere-
oscopy, motion tracking and augmented reality. The experi-
ment employed a system allowing the coach to hold a training
session without the need for his presence in the training hall.
He connected remotely with his protégés located in the hall
using a high definition (HD) videoconferencing tool. The
system enabled him to observe the athletes performing their
gymnastics routines and, afterwards, to give them advice
while reviewing an instant replay with slow motion capabili-
ties. Additionally, the coach is able to review and present
archival footage of athletes recorded with stereoscopic (3D)
HD cameras. This footage also includes a 3D model of a
human body reflecting the athlete's movements collected via
motion tracking. The stream with the animated avatar allowed
the coach to analyse the depth of the athlete's motions and
give the athlete more meaningful feedback.

ENHANCING
USER EXPERIENCE
Instant replays in 3D and slow motion
help athletes review performance and
understand coaches remarks. HD
video conferencing with stereoscopy
make the remote training session a
valid alternative to personal interac-
tion.
BENEFITS TO CAR
The system proved to be useful for
sports training applications. The
venue found it beneficial to make use
of the system’s possibilities in the
training process. The tests have
proven that it is feasible to set up
such a system in a real-life training
hall and that its performance is satis-
factory for the purposes evaluated in
the scenario. Making coaches availa-
bility remotely increases efficiency
and reduces costs.
FUTURE
OPPORTNITIES
The platform developed demonstrat-
ed the potential to CAR who have
learned what is possible. The next
steps require procurement of the
supporting infrastructure (cameras,
PC, capture cards) and small devel-
opments to provide remote coaches
additional features.

non-invasive
3D reconstruction of biomechanics
KEY FEATURES:
MOTIVATION
3D Media In Sports investigates the usefulness of 3D infor-
mation in weightlifting and cycling high performance sports
training processes. 3D information is a key element for accu-
rate and productive training in many aspects. For instance,
information that in the past was captured either solely by the
trainer and interpreted thanks to their experience (such as
joint kinematics or an aerodynamics profile) or from wearable
devices that can affect the athlete’s performance, can now be
automatically gathered by low cost non-invasive sensing
devices and processed in real-time providing useful feedback
to the user (trainer and/or athlete). By being able to accurate-
ly manipulate this information a whole new world of opportu-
nities emerges in the Future Media Internet (FMI).
TECHNICAL INNOVATION
The Microsoft Kinect was a breakthrough device for capturing
3D information but natively has various problems. Sophisti-
cated algorithms were developed to improve accuracy for the
demands of high performance sport. The algorithms provide
correction of inaccurate depth estimation, constrain the Ki-
nect’s calculated human skeleton data to physical poses to
enhance reliability, as well as many more enhancements that
are particularly suitable for sports biomechanics. Novel algo-
rithms were developed for two use cases (weightlifting and
cycling). For weightlifting the trajectory of the bar was tracked
including its velocity and angle, and the knee angle of the
weightlifter was also recorded. For cycling, aerodynamics
variables such as the cyclist’s frontal area, arm-torso angle,
horizontal axis-torso angle and forearm-arm angle are calcu-
lated. EXPERIMEDIA offers a unique combination of 3D
based biomechanical information enabling more novel appli-
cation domains.

mance using low cost non-
invasive visual and depth
sensors

ments are captured without the re-
strictions associated with invasive
sensors attached to their body. The
system can be easily installed in the
field rather than needing to go to a
laboratory environment.

BENEFITS TO CAR
The biomechanical measurements showed
promising results. In weightlifting the accura-
cy of the trajectory was correct but the joint
kinematics were not reliable enough due to
the fast movements of the weightlifter. The
results for the frontal area in cycling are
encouraging. High performance sports train-
ing centres such as CAR benefit from the use
of such technologies and can provide better
services to their athletes and trainers increas-
ing productivity of training sessions at a
fraction of the cost.
FUTURE OPPORTNITIES
With the launch of Kinect HD later in 2013 the
accuracy of the algorithms will be increased
dramatically. Since 3D biomechanical infor-
mation can be streamed over the Internet
seamlessly and accurately, sports communi-
ties using dedicated social media can benefit
from the use of such information and its
integration into new 3D media services.

accurate analysis of
choreographed team sports
KEY FEATURES:
MOTIVATION
Live Synchro demonstrates a new procedure to improve the
accuracy and execution of the performance of the synchro-
nized swimming (“synchro”) teams on a mandatory routine of
the Olympic Games. In a sport like synchro, having pro-
cessed audio-visual content and being able to watch and
learn from it can improve the training results, but today train-
ing sessions are captured and processed manually. Live
Synchro aims to put professional audio-visual acquisition and
production tools into the hands of coaches allowing them to
provide real-time feedback at the pool side. Can technologies
enhance the process to improve the execution, quality and
accuracy of the synchronized swimming routines including
quality of the artistic and technical results? Can the FMI
increase the quality of training sessions by more effective
feedback, increasing collaboration with remote trainers and
making it easier for athletes to make their own contributions
to choreographies?
TECHNICAL INNOVATION
Audio-visual media services are at the heart of the system
providing streaming to internet, streaming to a local player,
remote control over streams, storage of a video (temporary or
archive) and transcoding. Sport-specific services are provid-
ed to annotate music choreographies, to manage training
sessions and the teams involved. Statistical information is
collected about the usage of the infrastructure in terms of
Quality of Service metrics reported to EXPERIMEDIA’s ECC.
This is important to understand the demands such novel
training processes place on the infrastructure at CAR.

BENEFITS TO CAR
Training processes would be more
efficient due to the reduction in the
time taken by coaches, athletes and
staff to manage and review audio-
visual content.
FUTURE
OPPORTNITIES

strating ideas and requires producti-
sation before production deployment.
The system is applicable to other
disciplines with similar characteristics
such as artistic gymnastics.

wireless sensor
motion capture and 3D visualisation
KEY FEATURES:
MOTIVATION
Quick delivery of performance data to the athletes and coach-
es is an essential part of any training programme. The availa-
bility of mobile devices (such as tablets, laptops, etc.) has the
potential to make data collection from sensors and providing
real-time feedback to athletes much easier. Sensors are
getting smaller allowing them to be worn by athletes without
restricting their movements. Add in Wi-Fi connectivity and
you can imagine systems where performance data is continu-
ous collected, transferred, processed and analysed through-
out training sessions. How do all these trends influence train-
ing programmes? That’s what the experiment was investigat-
ing.
TECHNICAL INNOVATION
3D Acrobatics carried out research on synchronization of
motion capture, video and metadata. Wireless inertial sen-
sors were used to capture biomechanics data which was
transferred to a local device for instantaneous visualisation of
athletes’ movements through a synchronised 3D model and
video. Specific biomechanical models were developed for the
Pommel Horse exercises to provide the data necessary for
assessment of the training process. The devices also connect
to a data management service hosted on a private cloud
making it available for further processing and sharing with the
community. The data from this experiment when connected
to CONFetti generated 3D models to be displayed in the HD
video conferencing system. The athlete has the possibility of
sharing her/his data with trainers, colleagues and friends who
might be geographically distributed, thus enlarging the experi-
ence to wider communities.
Enhancing visitor experi-
ence using gamification of
learning, collective interac-
tive role playing and immer-
sive experiences
ENHANCING
USER EXPERIENCE
Wireless sensors make measure-
ments possible in the field without
having to go to the laboratory.
BENEFITS TO CAR
Sports scientists now understand the
strengths and limits of current inertial
sensors and have experienced ap-
proaches for incorporating wireless
sensor technologies into athlete’s
training programmes.
FUTURE
OPPORTNITIES
The experiment highlighted some
limitations for the use of inertial sen-
sor for gymnastics disciplines. CAR
identified other activities such as
football, cycling and rehabilitation
where the technology would be more
suitable. These are now being ex-
plored by STT.
