QoMEX2014 - Analysing the Quality of Experience of Multisensory Media from Me...Jacob Donley
This presentation was given at QoMEX 2014, the 6th International Workshop on Quality of Multimedia Experience.
Abstract:
This paper investigates the Quality of Experience (QoE) of multisensory media by analysing biosignals collected by electroencephalography (EEG) and eye gaze sensors and comparing with subjective ratings. Also investigated is the impact on QoE of various levels of synchronicity between the sensory effect and target video scene. Results confirm findings from previous research that show sensory effects added to videos increases the QoE rating. While there was no statistical difference observed for the QoE ratings for different levels of sensory effect synchronicity, an analysis of raw EEG data showed 25% more activity in the temporal lobe during asynchronous effects and 20-25% more activity in the occipital lobe during synchronous effects. The eye gaze data showed more deviation for a video with synchronous effects and the EEG showed correlating occipital lobe activity for this instance. These differences in physiological responses indicate sensory effect synchronicity may affect QoE despite subjective ratings appearing similar.

It’s a well-known fact that eye tracking can provide some interesting insight into how people process information. But how can user experience professionals determine if eye tracking is indeed a useful addition to their studies? Our complimentary webinar, “No, But Really, Do I Need Eye Tracking?,” addressed this subject by discussing the benefits of eye tracking and the proper application of the method.
During the webinar, Aga Bojko, VP, User Experience, spoke candidly about when to use and, perhaps more importantly, when not to use eye tracking. Bojko described both qualitative and quantitative types of findings that can be obtained with eye tracking research, and explained how to decide whether or not stakeholders benefit from this method. This presentation outlines example situations in which eye tracking is most effectively utilized, from determining the ease of new drug label differentiation from existing labels to evaluating which package design will be most effective on a shelf.
This presentation was made at Web Essentials 05. It provides a general overview of user testing and then follows on to show how Eye Tracking can be used in conjunction with traditional Usability techniques, providing more detailed results. A number of case studies are included to support the discussion.

Spike removal through multiscale wavelet and entropy analysis of ocular motor...Giuseppe Fineschi
Wavelet decomposition of ocular motor signals was investigated with a view to its use for noise analysis and filtering. Ocular motor noise may be physiological, depending on brain activities, or experimental, depending on the eye recording machine, head movements and blinks. Experimental noise, such as spikes, must be removed, preserving noise due to neuro-physiological activities. The proposed method uses wavelet multiscale decomposition to remove spikes and optimizes the procedure by means of the covariance of the eye signals. To measure the noise on eye motor control, we used the wavelet entropy. The method was tested on patients with cerebellar disorders and healthy subjects. A significant difference in wavelet entropy was observed, indicating this quantity as a valuable measure of physiological motor noise.
Automatic eye fixations identification based on analysis of variance and cova...Giuseppe Fineschi
Eye movement is the simplest and repetitive movement that enables humans to interact with the environment. The common daily activities, such as reading a book or watching television, involve this natural
activity, which consists of rapidly shifting our gaze from one region to another. In clinical application, the
identification of the main components of eye movement during visual exploration, such as fixations and
saccades, is the objective of the analysis of eye movements: however, in patients affected by motor control disorder the identification of fixation is not banal. This work presents a new fixation identification
algorithm based on the analysis of variance and covariance: the main idea was to use bivariate statistical
analysis to compare variance overxandyto identify fixation. We describe the new algorithm, and we
compare it with the common fixations algorithm based on dispersion. To demonstrate the performance
of our approach, we tested the algorithm in a group of healthy subjects and patients affected by motor
control disorder

Visual search is an everyday activity that enables
humans to explore the real world. Given the visual input,
during a visual search, it’s required to select some aspects of the input in order to move to the next location. Exploration is guided by two factors: saliency of image (bottom-up) and endogenous mechanism (top-down). These two mechanisms interact to perform an efficient visual search. We developed a stochastic model, the ”break away from fixations” (BAF), to emulate the visual search on a high cognitively demanding task such as a trail making test (TMT). The paper reports a case study providing evidence that human exploration performs an efficient visual search based also on an internal model of regions already explored.

Bayesain Hypothesis of Selective Attention - Raw 2011 posterGiacomo Veneri
The aim of the study is to understand the process of target averaging during the selection process. We analyzed the probability to select the target after a fixation outside ROIs from the duration of fixations and the distance to the target. We aimed to respond to the question “is it possible to predict the selected area?” . In this study we tested the presence of information in non-ROI fixation data about the occurrence of a target at the next saccade. A classification algorithm was trained to predict the target vs. non-target outcome (dependent variable) of a saccade from summary statistics of fixation data (covariates). We claim that significantly accurate predictions are substantial evidence to support the hypothesis of "presence of information".

While there are many neuroimaging modalities to study the brain, each comes with its own set of benefits and limitations. MRI and EEG can record from the whole brain, but it comes at the price of limited spatiotemporal resolution and low sensitivity. Recently, functional ultrasound (fUS) imaging has made a name for itself, with its ability to image the full depth of the brain and provide a quantitative view of brain activation and connectivity.
In this webinar, Dr. Pierre Pouget discusses the use of fUS imaging to assess local changes in cerebral blood flow in awake, behaving non-human primates. He provides an overview of fUS technology and highlight recent and ongoing research showing how unexpected functions can be tracked in the fronto-medial cortex.
Dr. Serge Picaud discusses the application fUS imaging to study the neural circuits underlying vision in rats and nonhuman primates. He presents recent research using fUS in rats to study activation of the visual system, and in NHPs to map brain activity and to study ocular dominance columns in the visual cortex.
Key topics will include:
Pierre Pouget
- Using fUS to assess brain activity in non-human primates in a single trial, without averaging
- Possibilities when coupling fUS with electrophysiology and pharmacology
- How fUS imaging can be used to track short and long-term variations in brain activation
Serge Picaud
- Studying activation of neuronal circuits with either prosthetics or optogenetic activation
- Procedure to generate retinotopic maps in behaving non-human primates
- Demonstrating the lateral and spatial resolution of fUS by imaging ocular dominance columns
Faro An Interactive Interface For Remote Administration Of Clinical Tests Bas...Kalle
A challenging goal today is the use of computer networking and advanced
monitoring technologies to extend human intellectual capabilities in medical decision making. Modern commercial eye trackers
are used in many of research fields, but the improvement of eye tracking technology, in terms of precision on the eye movements capture, has led to consider the eye tracker as a tool for vision analysis, so that its application in medical research, e.g. in ophthalmology, cognitive psychology and in neuroscience has grown considerably. The improvements of the human eye tracker interface become more and more important to allow medical doctors to increase their diagnosis capacity, especially if the interface allows them to remotely administer the clinical tests more appropriate for the problem at hand. In this paper, we propose a client/server eye tracking system that provides an interactive system for monitoring patients eye movements depending on the clinical test administered by the medical doctors. The system supports the retrieval of the gaze information and provides statistics to both medical research and disease diagnosis.

Measuring visual acuity and contrast sensitivity by optomotor reflex in rodentsInsideScientific
There is a growing need for behavioral readouts to monitor disease progression and to assess the success of a potential therapy. In vision research, observing the optomotor reflex (OMR) is an important and widely established method for assessing visual acuity and contrast sensitivity in rodents. These tests can be performed with freely moving animals without any need for anaesthesia or restraints. In addition, since OMR is a reflex-based behavior, observing it does not require any training of the animal.
In this webinar, sponsored by Striatech and supported in part by Stoelting, researchers will present objective and bias-free results obtained using a newly developed automated optomotor system.

In proteomics, two dimensional gel electrophoresis (2–DE) is a separation technique for proteins.
Gel electrophoresis is registered and the final digital image is computer analyzed for protein spots finding; the protein spots can be detected by visual inspection of a digital gel image or by image processing algorithm. On computer image analysis, difficulties arise from image noise, spot saturation and irregular geometric distortions.
Aiming at the automated analysis of large series of 2–DE images, the bottleneck is to solve the two most basic algorithmic problems: identifying protein spots and computing the protein spots map in order to compare it to database or different image.
We developed a robust Analysis of Variance (ANOVA) based algorithm able to excite spot in order to be easy found and separated by classic algorithm as edge detection or watershed.

The eye gaze analysis represents a challenging field of
research, since it offers a reproducible method to study the mechanisms of the brain. Eye movements are arguably the most frequent of all human movements and an essential part of human vision: they drive the fovea and consequently, the attention towards regions of interest in space. This enables the visual system to fixate and to process an image or its details with high resolution: act of fixation. This chapter investigates some common techniques and algorithms to study human vision.

EVA – EYE TRACKING - STIMULUS INTEGRATED SEMI AUTOMATIC CASE BASE SYSTEMGiacomo Veneri
In a real world visual search is a common task depending from
sensory, perceptual and cognitive processes. Different classes
of eye movements are necessary to hold an image on the retina
during head rotation or movement of the image, and to move
the eye suddenly to a new point of interest in space. From a
functional point of view, two major classes of eye movements
are described in humans: those stabilizing gaze (optokinetic
nystagmus, oculovestibular reflex) and those movinggaze
(saccades, pursuits and vergence). Under natural conditions,
however, a mix of all kinds of eye movements permit
continuous scanning of the visual scene. The sequence of
fixations and saccades during visual exploration isan
expression of a number of cognitive processes; the use of
standardized tasks with pre-defined spatial-temporal variables
allows us to assess specific cognitive domains, such as
perception, attention, memory, preference and motivation.
Manipulating the search task can vary the demands on brain. In
turn, brain modulates visual search by selecting and limiting
the information available at various levels of processing.
The EVA software is a complete system based on a set of
stimulus and patient’s case able to stress brain functionalities in
order to assess some cognitive functions.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

3. Selective Attention
• Selective attention ( Posner,
1980) is the process to select
some region of the scene to
be processed in detail; then,
selective attention works as
filter.
• Top-Down: attentional process
that influences sensory
processing in an automatic
and persistent manner
• Bottom-Up: influence on the
nervous system due to
extrinsic properties of the
stimuli

4. Motor Control and Cerebellum
• The neuronal circuitry of the
cerebellum is thought to
encode internal models that
reproduce the dynamic
properties of body parts
(Kelly2003,Ito2005,Ito2006a).
• These models control the
movement allowing the brain
to precisely control the
movement without the need
for sensory feedback
(Barlow2002,Ito2008,King2011
)

14. Motor Control Noise Evaluation
• (Beers2007, Veneri2011)
gaze noise may be additive
with or multiplicative of the
eye movement, and is lost
in recording noise (RN) due
to blinks or signal loss;
• noise = PN + RN = SDN
(signal) + ADN + RN where
SDN is physiological signal
dependent noise and ADN
physiological additive noise.

27. Selective attention
• DT provided a indicator to under-
stand the ability of humans to
converge to the target.
• ANOVA reported significant
difference among groups (F
(2, 35) = 9.476, p < 0.01)
• post-hoc Sidak procedure
confirmed significant
difference between
– CTRL-SCA2 (p CTRL−SCA2 < 0.01),
– CTRL-NDC (p NDC−SCA2 ≤ 0.01);
– no significant dif-ference was
found between SCA2-NDC (p
SCA2−NDC = 0.622).

28. Correlation DT-E
• Pearson and Spearman test reported correlation between E and DT
for NDC patients (p < 0.05, ρ = 0.892, A), and correlation for SCA2
patients (p < 0.05, ρ = 0.736, B) not confirmed by Spearman (p =
0.18). No correlation was found for CTRL subjects (p = 0.43).

30. Summary
• In the current work two methods have been developed:
• Selective attention evaluation
• Entropy analysis through wavelet decomposition.
• Both methods are based on eye tracking
• Subjects and patients cannot control eye movements or
fixations perfectly, then, analysing eye motor entropy it is
possible to extract some important features and conclusions.

32. Study the influence
• Does the motor control (cerebellum) influence
selective attention?
Giacomo Veneri – EVALab - Dep. Neurological and Behavioral Science - UNISI
32
33. Cerebellum could influence selective
attention (Top-Down) sending
afferent information of noise in order
to minimize the functional
cost of energy.
Our hypothesis is systematically
supported by recent application of
opti-mal control theory; (Najemnik &
Geisler, 2005), (Beers, 2007) and
(Osborne, 2011) argued that humans’
vision is an optimal mechanism
minimizing the
effect of motor or cognitive noise. Our
findings are compatible with this
hypothesis: patients preferred sparser
fixations avoiding saccade directed to
the
target. The non correlation of DN with
WS suggested that this mechanism
was a strategy to minimize the effort
to control saccade rather than a direct
influence on visual search.
