Energy expenditure during operational circumstances: An approach using and improving available monitoring systems recently applicated in Units of the Dutch Armed Forces

Purpose: Light infantry units, such as the Royal Netherlands Marine Corps and the Dutch Airmobile Brigade, are expected to carry out multiple-day missions in isolated and challenging environments with limited access to supplies. Next to exceptional resilience, these operations also require a tailored energy balance. As such, the capability to...

The relative contribution of five key perceptual cues and their interaction to the sense of embodiment

A range of perceptual cues drive the Sense of Embodiment (SoE) with an external object, such as a virtual arm that looks like one’s own or can be controlled like one’s own. Since most experiments test one or two cues at a time, it is difficult to establish their relative contribution and possible interaction. This work aims at investigating the...

Pupil Diameter as Implicit Measure to Estimate Sense of Embodiment

We explore pupil diameter (PD) as estimator of Sense of Embodiment (SoE) using data of three user studies. We hypothesize that pupil diameter reflects SoE in a direct and indirect way. If individuals feel strongly embodied, presenting an emotional stimulus like a threat to the surrogate will produce a strong response, as if the stimulus would be...

The effects of mass, bulk and stiffness of personal protective equipment and clothing on physical performance when performing a military mobility obstacle course

Background. Soldiers are required to conduct tasks and operations in physically demanding situations, where the ability to move (mobility) quickly is important to lethality and survivability. This study employed a specially designed suit to try to isolate the main mass property characteristics of personal protective clothing/equipment (PPCE)...

The added value of musculoskeletal simulation for the study of physical performance in military tasks

The performance of military tasks is often exacerbated by additional load carriage, leading to increased physical demand. Previous studies showed that load carriage may lead to increased risk of developing musculoskeletal injuries, a reduction in task speed and mobility, and overall performance degradation. However, these studies were limited to...

Embodiment and Performance in the Supernumerary Hand Illusion in Augmented Reality

In teleoperations, robots are generally used because related tasks are too dangerous, uncomfortable or impossible for humans to perform. When using augmented reality to control robotic limbs in such teleoperations, it is essential to understand how these extra virtual limbs are experienced. In particular, the relationship between the embodiment...

Isolated amd combined effects of mass, bulk an stiffness of clothing and equipment on leap performance using a newly developed clothing and equipment characteristics suit

TS24. LOAD EFFECTS ASSESSMENT PROGRAM (LEAP) – ASSESSING DISMOUNTED SOLDIER PHYSICAL PERFORMANCE

Two isothermal challenges yield comparable physiological and subjective responses

Purpose: Ventilated vests are developed to reduce thermal stress by enhancing convective and evaporative cooling from skin tissue underneath the vest. The purpose of this study is to investigate whether thermal stress is equal when a ventilated vest is worn compared to a no-vest situation with similar dry thermal resistance. Methods: Nine...

Haptic Feedback in a Teleoperated Box & Blocks Task

Haptic feedback is a desired feature in teleoperation as it can improve dexterous manipulation. Direct force feedback to the operator’s hand and fingers requires complex hardware and therefore substituting force by for instance vibration is a relevant topic. In this experiment, we tested performance on a Box & Blocks task in a teleoperation set...
