The Triangle Orientation Discrimination (TOD) test method was applied to characterize thermal and visual range performance of the Gatekeeper Electro Optical Security System. Gatekeeper developed by Thales Nederland BV, is currently in use with the Royal Netherlands Navy. The system houses uncooled infrared and colour TV cameras providing up to...

Night vision equipment is crucial in order to accomplish supremacy and safety of the troops on the battlefield. Evidently, system integrators, MODs and end-users need access to reliable quantitative characterization of the expected field performance when using night vision equipment. The Image Intensifier tube is one of the most important...

We investigated whether manipulation of visual and auditory depth and speed cues can affect a user’s sense of risk for a low-cost nonimmersive virtual environment (VE) representing a highway environment with traffic incidents. The VE is currently used in an examination program to assess procedural knowledge of highway patrol officers. In its...

We investigate how human visual search performance with field of view (FOV) restrictions depends on scan speed, zoom factor, target location, and conspicuity. First, observers search a FOV that moves at a constant speed along a predefined path over a visual search scene (the field of regard, or FOR), and we measure the effects of scan speed,...

Search and detection are two everyday jobs of many biological systems, performed almost innately, either consciously or subconsciously and necessary for survival. Search and target detection, in particular, are the first stages in visual observation tasks associated with military target acquisition, industrial inspection, traffic control, and...

We present a new method to derive a multiscale urban camouflage pattern from a given set of background image samples. We applied this method to design a camouflage pattern for a given (semi-arid) urban environment. We performed a human visual search experiment and a computational evaluation study to assess the effectiveness of this multiscale...

The MRTD and MRC end-to-end EO/IR system tests and corresponding models, described in NATO STANAGs 4347-4351, lead to incorrect Target Acquisition (TA) range predictions for modern imaging systems that are 1) usually under-sampled and/or 2) contain complex signal processing. Considerable efforts have been made to develop tests and models that...

Within the EU FP7 project SILENV, noise and vibration measurements were carried out on several ships. These objective measures were accompanied by subjective measures recorded through questionnaires. With this, we developed models describing the relationship between the levels of noise and vibration on board ships and subjective ratings on...

De publicatie is een combinatie van de resultaten van TNO projecten over crisiscommunicatie en zelfredzaameheid van burgers. Wat doe je als er in je omgeving iets gebeurt? Een overstroming, een opstootje of een ongeluk? Of als de stroom langdurig uitvalt, gas of water afgesloten raken in een strenge winter? En wat als er in je huis of kantoor...

This paper presents a usage-centered evaluation method to assess the capabilities of a particular Unmanned Ground Vehicle (UGV) for establishing the operational goals. The method includes a test battery consisting of basic tasks (e.g., slalom, funnel driving, object detection). Tests can be of different levels of abstraction, and be performed in...

A total of 15 TDs were included as part of HFM-170. These TDs are listed in Figure 1-3, along with the Host country. TDs focused on many critical issues including multi-vehicle control, manned-unmanned teaming, human-automation interaction, telepresence interfaces, delegation interfaces, vehicle hand-offs, operator workload adaptive systems,...

Human-in-the-loop field tests of human-robot operations in high-demand situations provide serious constraints with respect to costs and control. A set of relatively simple unit tasks might be used to do part of the testing and to establish a benchmark for human-robot performance and situation awareness. For an urban search and rescue (tunnel...

Non-parametric Wilcoxon Matched Pairs tests show that the percentage correct target ID in the Telepresence condition is significantly higher (87.5%) than in both Mono-Joystick (61.5%; p < .05) and Mono-Headtracking (64.6%; p < .005); Mono-Headtracking and MJ do not differ (p = .51). The repeated measures ANOVA on time to target identification...

This underlying report describes how HFM-170 successfully developed and demonstrated pertinent supervisory control human-system interface design practices and operator interface concepts for Uninhabited Vehicles (UVs) network-centric operations. In a series of 14 specific Technology Demonstrations (TDs) it was shown that the operator’s role is...
