Perceptions of Two Unique Lane Centering Systems: An FOT Interview Analysis

Objective: The goal of this interview analysis was to explore and document the perceptions of participants in a field operational test (FOT) including two unique lane centering systems (S90’s Pilot Assist, and CT6’s Super Cruise). Both systems offer similar functionality on paper (continuous longitudinal and lateral vehicle control), but have drastically different HMI implementations. Methods: Twenty-four drivers (16 male, 8 female) in the Greater-Boston Area participated in an FOT study, in which each participant drove one of two vehicles for a month. Upon vehicle return, drivers took part in a 30 to 60-minute semi-structured interview to record their perceptions of the vehicle’s various ADAS systems. Transcripts of the interviews were coded by two researchers to assign each participant’s statements to specific vehicle technologies as well as to attribute perceptions to each statement. The analyses in this paper focus on adaptive cruise control (ACC) and lane centering technologies. Results: Participants cite perceived positive benefits, such as increased safety and comfort provided by lane centering and adaptive cruise control systems, but also cite concern over the possibility…

Lookie Here! Designing Directional User Indicators Across Displays in Conditional Autonomous Vehicles

To be published on 2020-04-14 by SAE International in United States
Based on the SAE’s classification (J3016), drivers’ attention will be gradually released from the driving task as the level of automation in the vehicle increases. It allows drivers to complete more non-driving related tasks in information and entertainment system. The trigger point for the major transition in driver control happens in the progression from level 2 to level 3 when the automated driving system (ADS) starts to perform a major part of the dynamic driving task (DDT) in the allowed conditions, but meanwhile it still needs the drivers are ready for takeover control or other interventions in a short time. In this paper, we investigated whether providing directional alerts to a user’s active screen with non-driving related tasks can augment their ability in regaining situational awareness on road hazard when traveling in a conditional autonomous vehicle. A user study (N=15) was conducted to compare solutions between the central and peripheral field across displays where subjects were seated in an autonomous vehicle simulator and distracted by playing a game on a tablet screen (iPad). With different…

Collaborative Automation: It's More Than Just the Cobot

  • Magazine Article
  • TBMG-35608
Published 2019-12-01 by Tech Briefs Media Group in United States

Collaborative robots, often called “cobots,” offer opportunities for companies of almost any size to cost-effectively automate processes that were previously out of reach. Cobots are available in a wide range of sizes, payloads, and capabilities but they all share attributes that define the term “collaborative.” The aspect that most people think of first is safety — the ability for cobots to work alongside human workers without bulky, expensive guarding. Cobots include a number of built-in safety mechanisms including rounded edges and softer materials as well as power-and force-limiting technologies that avoid injury and minimize discomfort in case of contact, and sensors that automatically slow or stop the robot arm if a human enters its workspace.

Artificial Skin Provides Haptic Feedback

  • Magazine Article
  • TBMG-35616
Published 2019-12-01 by Tech Briefs Media Group in United States

Technology capable of replicating the sense of touch — also known as haptic feedback — can greatly enhance human-computer and human-robot interfaces for applications such as medical rehabilitation and virtual reality. A soft artificial skin was developed that provides haptic feedback and, using a self-sensing mechanism, has the potential to instantaneously adapt to a wearer's movements.

Identifying Automated Driving Systems-Dedicated Vehicles (ADS-DVs) Passenger Issues for Persons with Disabilities

On-Road Automated Driving (ORAD) committee
  • Ground Vehicle Standard
  • J3171_201911
  • Current
Published 2019-11-19 by SAE International in United States
It is expected that Level 4 and 5 automated driving systems-dedicated vehicles (ADS-DVs) will eventually enable persons to travel at will who are otherwise unable to obtain a driver's license for a conventional vehicle, namely, persons with certain visual, cognitive, and/or physical impairments. This information report focuses on these disabilities, but also provides guidance for those with other disabilities. This report is limited to fleet operated on-demand shared mobility scenarios, as this is widely considered to be the first way people will be able to interact with ADS-DVs. To be more specific, this report does not address fixed route transit services or private vehicle ownership. Similarly, this report is focused on road-worthy vehicles; not scooters, golf carts, etc. Lastly, this report does not address the design of chair lifts, ramps, or securements for persons who use wheeled mobility devices (WHMD) (e.g., wheelchair, electric cart, etc.), as these matters are addressed by other committees within SAE International.

Controlling Wheelchairs with a Wearable Brain-Machine Interface

  • Magazine Article
  • TBMG-35505
Published 2019-11-01 by Tech Briefs Media Group in United States

Combining new classes of nanomembrane electrodes with flexible electronics and a deep learning algorithm could help disabled people wirelessly control an electric wheelchair, interact with a computer or operate a small robotic vehicle without donning a bulky hair-electrode cap or contending with wires.

Less Training Needed for Brain-Machine Interfaces

  • Magazine Article
  • TBMG-35338
Published 2019-10-01 by Tech Briefs Media Group in United States

Brain-machine interfaces (BMIs) are rarely found outside of medical clinics, where the disabled receive hours or days of training in order to operate wheelchairs with their minds. Now the largest-ever BMI experiment Mental Work, conducted as an experimental artwork at EPFL's Artlab, has provided preliminary evidence that training time can be shortened, the use of dry electrodes are a robust solution for public BMI and that user performance tends to improve within a relatively short period of time.
