Ontology-Based Reflective Communication for Shared Human-AI Recognition of Emergent Collaboration Patterns

When humans and AI-agents collaborate, they need to continuously learn about each other and the task. We propose a Team Design Pattern that utilizes adaptivity in the behavior of human and agent team partners, causing new Collaboration Patterns to emerge. Human-AI Co-Learning takes place when partners can formalize recognized patterns of...

Fixed viewport applications for omnidirectional video content Combining traditional and 360 video for immersive experiences

With omnidirectional videos, the viewer is able to direct her Field-of-View (FoV) to any part of the scene while watching the content. This is achieved by rendering the 360 video content on the inside of a (conceptual) sphere in which the viewer is typically placed at the center. This is in contrast with traditional video that is rendered on a...

Quantifying the uncertainty of event detection in full motion video

Algorithms for the detection and tracking of objects can be combined into a system that automatically extracts relevant events from a large amount of video data. Such a system , can be particularly useful in video surveillance applications, notably to support analysts in retrieving information from hours of video while working under strict time...

An evaluation of speed management measures in Bangladesh based upon alternative accident recording, speed measurements, and DOCTOR traffic conflict observations

With 21,000 people annually killed in road traffic (estimated figure by World Health Organization), Bangladesh has one of the highest fatality rates in the world. Vulnerable road users (VRUs) account for over 50% of road traffic casualties, and 70% of casualties occur in rural areas. As in many Low and Middle Income Countries (LMICs), the...

Detection and tracking of humans from an airborne platform

Airborne platforms are recording large amounts of video data. Extracting the events which are needed to see is a timedemanding task for analysts. The reason for this is that the sensors record hours of video data in which only a fraction of the footage contains events of interest. For the analyst, it is hard to retrieve such events from the...

An audio-visual dataset of human-human interactions in stressful situations

Stressful situations are likely to occur at human operated service desks, as well as at human-computer interfaces used in public domain. Automatic surveillance can help notifying when extra assistance is needed. Human communication is inherently multimodal e.g. speech, gestures, facial expressions. It is expected that automatic surveillance...

Predictive validity of the Hand Arm Risk assessment Method (HARM)

The Hand Arm Risk assessment Method (HARM) is a simplified risk assessment method for determining musculoskeletal symptoms to the arm, neck and/or shoulder posed by hand-arm tasks of the upper body. The purpose of this study was to evaluate the predictive validity of HARM using data collected from a three year prospective cohort Study on...

Traffic noise and vehicle movement at a controlled intersection

Traffic noise at an intersection controlled by traffic lights shows noise level variations due to the alternating green and red lights for the different trafficstreams. Noise peaks caused by automobiles pulling up or passing by at highspeed may be quite annoying for people living near the intersection. Detailedprediction of the variations is...

Do work-related physical factors predict neck and upper limb symptoms in office workers?

Examination of the influence of physical exposure at work on neck and upper limb symptoms in office workers. Data were used from a prospective cohort study with a follow-up period of 3 years. Independent variables were physical exposure at work, observed and self-reported. Outcome measures were neck–shoulder symptoms and elbow–wrist–hand...

Simultaneous measurement of foveal spectral reflectance and cone-photoreceptor directionality

An instrument for simultaneous measurement of foveal spectral reflectance and cone-photoreceptor directionality is described. The key element is an imaging spectrograph (spectral range of 420–790 nm) with its entrance slit conjugate to the pupil plane of a human eye. A 1.9-deg spot on the retina is sampled in 1 s. Video observation of the retina...

Are neck flexion, neck rotation, and sitting at work risk factors for neck pain? Results of a prospective cohort study

Objective: To study the relation between neck pain and work related neck flexion, neck rotation, and sitting. Methods: A prospective cohort study was performed with a follow up of 3 years among 1334 workers from 34 companies. Work related physical load was assessed by analysing objectively measured exposure data (video recordings) of neck...

Flexion and rotation of the trunk and lifting at work are risk factors for low back pain: Results of a prospective cohort study

Study Design: A 3-year prospective cohort study among workers of 34 companies in the Netherlands. Objectives: To investigate the relation between flexion and rotation of the trunk and lifting at work and the occurrence of low back pain. Summary of Background Data: Previous studies on work-related physical risk factors for low back pain either...

Emperical validation of team training ID-Guidelines

With respect to team training, traditional instructional design (ID) guidelines, mainly aimed at training at the individual level, seem to be insufficient given the different nature and characteristics of teams and team performance. In order to provide adequate support, guidelines have been developed supporting the analysis of team tasks, and...

Contribution of the otholiths to the human torsional vestibulo-ocular reflex

The dynamic contribution of the otoliths to the human ocular torsion response was examined during passive sinusoidal body roll about an earth-horizontal axis (varying otolith input) and about an earth-vertical axis (unvarying otolith input). At a fixed amplitude of 25°, the stimulus frequency was varied from 0.05 to 0.4Hz. The otoliths affected...
