Collision Warning Systems

Abstract Vehicle technologies have the potential to greatly improve road safety. Given normative changes in cognitive, sensory and physical functioning, older drivers may particularly benefit from such technologies. However, little research has examined older adults’ opinions of vehicle technologies, descriptive differences of individuals more likely to have positive opinions of vehicle technologies, and how their opinions may differ depending on the type of vehicle technology. The current study examined older adults’ opinions on vehicle technology in a sample of 72 adults between 65 and 85 years (M = 72.3, SD = 5.36, 48% women). Participants were asked, “How important is [parking assistance, crash avoidance systems, early collision warnings, built-in GPS] in choosing a new vehicle?” on a scale from 1 (“not at all”) to 5 (“must have”). On average, participants rated built-in GPS as the most important (M = 3.81, SD=1.10) with parking assist as the least important (M=1.86, SD=1.13). We used correlational analyses to examine the association between demographic and personality and importance ratings. Women were more likely to rate greater importance for built-in GPS than men (r=.35, p<.05). Age, education, self-reported driving quality, and self-reported average weekly driving miles were not significantly associated with importance rating. In terms of personality, only higher levels of extraversion were associated with more positive ratings of early collision warning systems (r=.24, p<.05). Vehicle technology design and education should take older adults’ preferences into account and consider individual differences, and future work should examine other predictors of vehicle technology preferences such as functional performance.

The use of technology has been suggested as a means of allowing continued autonomous living for older adults, while reducing the burden on caregivers and aiding decision-making relating to healthcare. However, more clarity is needed relating to the Activities of Daily Living (ADL) recognised, and the types of technology included within current monitoring approaches. This review aims to identify these differences and highlight the current gaps in these systems. A scoping review was conducted in accordance with PRISMA-ScR, drawing on PubMed, Scopus, and Google Scholar. Articles and commercially available systems were selected if they focused on ADL recognition of older adults within their home environment. Thirty-nine ADL recognition systems were identified, nine of which were commercially available. One system incorporated environmental and wearable technology, two used only wearable technology, and 34 used only environmental technologies. Overall, 14 ADL were identified but there was variation in the specific ADL recognised by each system. Although the use of technology to monitor ADL of older adults is becoming more prevalent, there is a large variation in the ADL recognised, how ADL are defined, and the types of technology used within monitoring systems. Key stakeholders, such as older adults and healthcare workers, should be consulted in future work to ensure that future developments are functional and useable.

Complicated Task

The autonomous vehicle technology has recently been developed rapidly in a wide variety of applications. However, coordinating a team of autonomous vehicles to complete missions in an unknown and changing environment has been a challenging and complicated task. We modify the consensus-based auction algorithm (CBAA) so that it can dynamically reallocate tasks among autonomous vehicles that can flexibly find a path to reach multiple dynamic targets while avoiding unexpected obstacles and staying close as a group as possible simultaneously. We propose the core algorithms and simulate with many scenarios empirically to illustrate how the proposed framework works. Specifically, we show that how autonomous vehicles could reallocate the tasks among each other in finding dynamically changing paths while certain targets may appear and disappear during the movement mission. We also discuss some challenging problems as a future work.

Performance Based Assessment

Abstract For older adults living in rural/suburban communities, driving is often their only means of transportation. Although considered safe drivers, drivers older than 70 years have higher crash rates with fatality rates amplified due to the increased frailty/fragility. However, research evidence clearly indicates that cognitive factors contribute to driving impairment in older adults. Occupational therapists, as experts in observation of functional performance, use the Assessment of Motor and Process Skills (AMPS), for measurement of performance in everyday activities using two scales (motor and process). Previously demonstrated as a sensitive tool for cognitive changes, this presentation will summarize the research outcomes between older adults with cognitive impairment (N=57+) and without (N=53) who completed a comprehensive driving evaluation. Analysis of the two samples using receiving operating curves suggests the AMPS has potentially excellent specificity and sensitivity, specifically AUC = 0.826(0.73-0.92) for motor, AUC = 0.909(0.84-0.98) for process, and AUC = 0.936(0.88-0.99) together.

Mortality Hazard Ratio

Abstract Declining energy may indicate homeostatic dysregulation and predict adverse health outcomes. We hypothesized that declining energy would predict greater frailty (1-10), greater mortality, and faster mood (CES-D) and cognition (3MS) decline over time. This observational cohort studies included 2,443 older adults (mean age=74.6, 62.5% White, 47.8% men) from the Health ABC Study with up to eight years of data. Energy was assessed using a single-item question about prior month’s energy (baseline mean=6.7, SD=1.7, range=0–10, lower=less energy). We used linear mixed models to create energy change scores (mean=-.07 points/year, SD=.05, range=-0.32-0.21, negative=decreased energy). In regression models adjusting for baseline outcome performance and energy and demographics, declining energy predicted greater frailty (β=-2.72, 95%CI = -3.39,-2.06), greater mortality (hazard ratio=.07, p<.001), and faster CES-D (β=-.93, 95%CI=-1.10,-0.75) but not 3MS decline. Energy changes are easy to assess and predict clinically-relevant outcomes. Future work should consider mechanisms of declining energy on disability-related outcomes.

This article demonstrates a multidisciplinary approach that proposes to augment future caregiving by prolonged independence of older adults. The human–robot system allows the elderly to cooperate with small flying robots through an appropriate interface. ASPIRE provides a platform where high-level controllers can be designed to provide a layer of abstraction between the high-level task requests, the perceptual needs of the users, and the physical demands of the robotic platforms. With a robust framework that has the capability to account for human perception and comfort level, one can provide perceived safety for older adults, and further, add expressively that facilitates communication and interaction continuously throughout the stimulation. The proposed framework relies on an iterative process of low-level controllers design through experimental data collected from psychological trials. Future work includes the exploration of multiple carebots to cooperatively assist in caregiving tasks based on human-centered design approach.

The California Air Resources Board has mandated that by 1998 2% of new vehicles sold in California must be zero emission, effectively, electric vehicles. This requirement is largely responsible for the electric vehicle development programs run by almost every global automobile manufacturer that does business in the United States. At present, no single electric vehicle technology, from battery type, to propulsion system, to vehicle design, represents a standard for a protoelectric vehicle industry. In this paper competing electric vehicle technologies are reviewed, leading public and private electric vehicle research programs worldwide are summarized, and the barriers faced by competing technological systems in terms of manufacturing and infrastructural requirements are examined.

The emergence of vehicle technologies that promote driver safety and convenience calls for investigation of the prevalence of driver assistance systems as well as of their use rates. A consumer driven understanding as to why certain vehicle technology is used remains largely unexplored. We examined drivers’ experience using 13 different advanced driver assistance systems (ADAS) and several reasons that may explain rates of use through a nationally-distributed survey. Our analysis focused on drivers’ levels of understanding and trust with their vehicle’s ADAS as well as drivers’ perceived ease, or difficulty, in using the systems. Respondents’ age and experience with Level 0 or Level 1 technologies revealed additional group differences, suggesting older drivers (55+), and those with only Level 0 systems as using ADAS more often. These data are interpreted using the Driver Behavior Questionnaire framework and offer a snapshot of the pervasiveness of certain driver safety systems.
