The appropriate design of positively activating content is pivotal for appropriate changes in users’ affective states. The presented study provided insight into the potential of non-invasive VR-based eye tracking for automated estimation of affective state induced by video content, in an explorative pilot study with seven elderly persons living in a nursing home.

For tablet-based cognitive trainings to be effective, regular practice seems to be required, highlighting the need for such trainings to be applicable not only in well-prepared laboratory settings, but also for continuous use at home. In order to raise the acceptance as well as the user-friendliness of such trainings to consequently increase training intensity, usability research is essential. Therefore, the aim of this study was to explore the experiences of people with Alzheimer’s disease (PwAD), relatives, and dementia trainers regarding the usability of a tablet-based dementia training practiced in the home setting.A qualitative study was performed within the ongoing randomized controlled trial of the project multimodAAL. In total 15 individual interviews (each 5 per target group) were conducted with people with mild AD, their relatives and dementia trainers, who were already assigned to the intervention group for at least 6 months, practicing a dementia training program, including physical and cognitive exercises on a tablet-PC at home. The interviews lasted 91.9 minutes on average. A qualitative content analysis was performed to analyze the data.Participants were predominantly female (73.3 %). PwAD and relatives stated that they had no previous experience with this type of computer-based cognitive training and had experienced the training as positive and enriching. Some relatives saw the joint performance as a meaningful activity with their loved ones. Participants confirmed that the different types of physical exercises (e.g., coordination, strength), presented in a video format were well feasible for PwAD. In this regard, some PwAD reported feeling a bit unchallenged. Relatives and dementia trainers recommended for the exercise videos to be more motivating and fun (e.g., direct motivational address by the gymnast in the video like in a tv show, colorful sportswear). Regarding cognitive exercises, participants appreciated the variety (e.g., quiz, puzzle, calculating) as well as the sequence of the different exercises within a training session. Dementia trainers and relatives perceived that exercises related to topics about past/biography (e.g., previous occupation, hobbies) and to religious/seasonal traditions (e.g., Christmas) were particularly appreciated among PwAD. In view of beneficial factors to complete a training session with its physical and cognitive exercises successfully, relatives and dementia trainers underlined that PwAD needed support in terms of (technical) guidance, motivation/feedback/praise, as well as hints/tips/thought-provoking impulses. Dementia trainers and relatives suggested that this could be achieved by a supporting person (e.g., dementia trainer) or an expansion of the program by written and verbal support (e.g., hint button, voice assistant).

Staying cognitively under control under these circumstances is a necessary condition to avoid useless risk-taking and particularly to provide accurate situation reports to remote units to be able to organize appropriate support in time. This work applied a flexible virtual reality (VR) training environment with the purpose to investigate the performance of reporting under rather realistically simulated mission conditions. In a pilot study, representative emergency forces of the Austrian volunteer fire brigade and paramedics of the Johanniter organization were subjected to a test program that tested a formalized reporting schema (LEDVV), inducing equivalent strain in both, real environment and VR-based training scenarios. Wearable psychophysiological measuring technology was applied to estimate the cognitive-emotional stress level under both training conditions. The results indicate that both situation reports achieve a rather high level of cognitive-emotional stress and should be thoroughly trained. Furthermore, the results motivate the use of VR environments for the training of stress-resilient decision-making behavior of emergency forces.","PeriodicalId":285612,"journal":{"name":"Cognitive Computing and Internet of Things","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132201555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Virtual Reality (VR) training environments offer a great opportunity to create realistic operational scenarios with appropriate levels of difficulty. To evaluate VR-based training regarding cognitive-emotional and physical strain, a pilot study with 13 first responders (firefighters and paramedics) was conducted. The study plan aimed to induce equivalent strain in both, real environment (‘RC’) and VR-based (‘VR’), training scenarios. In summary, the results indicate that training sessions in real and in VR-based environments have a comparable impact on physical strain, on different dimensions of workload like physical and cognitive demand, and specific physical and emotional states. Most important, we could show that physical strain, which is a critical factor for appropriate training of first responders, cannot only be induced by traditional real-life training, but also by an immersive VR training environment. These results confirm and motivate the use of VR environments for the training of stress-resilient decision-making behaviour for emergency forces.","PeriodicalId":285612,"journal":{"name":"Cognitive Computing and Internet of Things","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114066663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several studies have delved into the first type of fatigue, there is a paucity of research on the decrease in WFFs’ cognitive performance. A decreased cognitive performance has been observed throughout multi-day suppression tasks, which could lead to poor decision-making and have unintended consequences on deployments. To our knowledge, the acute effect of tasks performed by WFFs on cognitive fatigue has not been studied. Therefore, the aim of this study was to analyze the effect of performing a specific circuit, which simulated the tasks performed by WFFs in their deployments, on central nervous system fatigue. Ten WFFs (34.4 ± 5.6 yr, 182.9 ± 6.1 cm and 92.8 ± 14.9 kg) participated in the study, who performed a field test composed of 4 specific tasks commonly used in their deployments. Each task was executed for 5 min interspersed by 90 s of recovery. This interval bout was repeated twice with 10 min of recovery in between. During the test heart rate (HR) and core temperature (CT) response were monitored. Both variables were used to calculate the physiological strain index (PSI). In addition, before and at the end of the field test, subjects’ critical flicker fusion (CFF) threshold was measured. The results obtained showed that the WFFs performed a high-exercise demand (mean HR, 85.3 ± 2.5% of maximal HR; CT, 38.3 ± 0.4 ºC and PSI, 6.0 ± 0.7). Despite this, CFF threshold measurements showed an increase (6.0 ± 6.0%, p < 0.05) in the sensory sensitivity threshold, suggesting an exercise induced increase in cortical arousal. Significant (p < 0.05) relationships between sensory sensitivity and time spent at high percentage of maximal HR (>90%), TC and PSI were found (r = -0.71, -0.74 and -0.69, respectively). In conclusion, the specific field test led an enhancement of sensory sensitivity and cortical arousal. However, the correlations found seem to indicate the potential negative effect of high-intensity exercise and thermal strain on central nervous system fatigue.\u0000","PeriodicalId":285612,"journal":{"name":"Cognitive Computing and Internet of Things","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126155052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we investigate what sensors and software tools we need to determine that we are working in ideal conditions, including good air quality, low CO2, etc. From an employee’s point of view, it is interesting if such monitoring devices can be easily used and combined. The evaluation should be possible and combinable by simple means. Why is this difficult?
