Abstract The concept of remotely operated, unmanned, and autonomous ships is creating increasing interest in the maritime domain, promising safety, increased efficiency sustainability. Shore control centers (SCCs) have been proposed to operate such vessels some industry projects are initiated. This paper aims at bringing knowledge about what a SCC envisioned be. It identifies explores challenges related designing developing SCCs through semi-structured interviews with research community...

Teleoperation in an environment with latency is difficult and highly stressful for human operators, resulting high cognitive workload decreased performance. This work investigates if a simple predictive display can increase performance lower subjective the operator when teleoperating remotely operated vehicle (ROV). A based on image transformation was developed by applying positional scale transformations to video feed tested. An experiment designed, consisting of navigational task...

Functional near-infrared spectroscopy (fNIRS) is often praised for its portability and robustness towards motion artifacts. While an increasing body of fNIRS research in real-world environments emerging, most studies are still conducted laboratories, do not incorporate larger movements performed by participants. This study extends applications conducting a single-subject observational yoga practice with considerable movement (Ashtanga Vinyasa Yoga) participant’s natural environment (their...

Abstract In navigation applications, Artificial Intelligence (AI) can improve efficiency and decision making. It is not clear, however, how designers should account for human cooperation when integrating AI systems in work. a novel empirical study, we examine the transition maritime domain towards higher levels of machine autonomy. Our method involved interviewing technology (n = 9) navigators aboard two partially automated ferries 5), as well collecting field observations one ferries. The...

Abstract This article introduces a Human-centred Engineering Design (HcED) practice, which values human aspects. practice engages deeply into (1) geometry and motion for specific tasks, (2) product manufacturing complexities through rapid prototyping, (3) the broader task context. cross-disciplinary method combines ergonomics, AM, sensor applications, multiple design practices. The framework provides concrete tasks to drive innovative designs in engineering. study, grounded research case...

Abstract Human-centred approaches within the design cycle are crucial to enhance usability and inclusivity of products. However, qualitative nature traditional human factors evaluation can create bottle necks, prompting need for more data driven methods. A framework data-driven is presented, looking integrate mixed-method approaches. Case studies illustrate its usage in real-world scenarios challenges summarised, calling robust collection methods, balancing mixed a explainable systems,...

Abstract This article presents an fNIRS experiment investigating cognitive differences between physical and digital prototyping methods in designers (N=25) engaged open constrained design tasks. Initial results suggest that yields increased hemodynamic response (i.e., brain activity) compared to design, the prefrontal cortex. Further work will seek triangulate by potential correlations processes outputs.

Tactile hands-only training is particularly important for medical palpation. Generally, equipment palpation expensive, static, or provides too few study cases to practice on. We have therefore developed a novel haptic surface concept training, using ferrogranular jamming. The concept's design consists of tactile field spanning 260 x 160 mm, and uses ferromagnetic granules alter shape, position, hardness palpable irregularities. Granules are enclosed in compliant vacuum-sealed chamber...

Abstract We replicate a design ideation experiment (Goucher-Lambert et al., 2019) with and without inspirational stimuli extend data collection sources to eye-tracking think aloud protocol provide new insights into generated ideas. Preliminary results corroborate original findings: have an effect on idea output questionnaire ratings. Near far increased participants’ fluency over time were rated more useful than control. further enable reproducibility publicly available data.

We present an experiment investigating concepts of affective state and workload in a large ship manoeuvring context. It is run on consumer simulator software where student participants (N=31) perform two ecologically valid scenarios: sailing open sea harbour. Results from surveys show highly significant changes terms both affect between the scenarios. Thus, one should consider varying affects workloads users contexts, consequently demanding new design paradigms for product development, such...

This white paper is conducted for Lean Business encompassing a first attempt at empirical testing of data extracted from the database. adhere to Startup Movement, where core principle that static business planning should be replaced with continuous dynamic model development and doing so increases chances success. To begin understand lean startup entrepreneurial behavior potential differences in focus on different canvas elements have been investigated. Based two samples, one use canvas, were...

This paper describes development of an experimental setup that enables convenient and fast integration low-cost, spring-loaded, dry electroencephalography (EEG) electrodes with a research-grade sensor cap. The proposed increases available electrode positions compared to the current equipment, constitutes pragmatic, low-cost approach for integrating EEG-measurements in combination other brain activity sensors. solution aims lower barrier including EEG as additional modality existing setups.

This work presents a modular research platform to design, test and run human-machine interaction (HMI) experiments. Traditionally, HMI experiments are time resource consuming, particularly in the piloting phase. Furthermore, such experiment setups often rigid only fit one particular hypothesis. Thus, significant is needed alter setup new hypotheses, if this possible at all. The presented technical proof-of-concept of highly flexible setup, which can rapidly be adapted alternative hypotheses....
