Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
E. Randel T. Osburn and Timothy McDonald Being Arrested, circa 1985
No full textE. Randel T. Osburn and Timothy McDonald are shown being arrested by police at a luncheon sponsored by Winn-Dixie at Atlanta's Waverly Hotel. Written on verso: SCLC Officials, Rev. Randel T. Osburn and Rev. Timothy MacDonald [sic] being arrested by Cobb County, Georgia police while attempting to address Winn Dixie's policies at a luncheon sponsored by Winn-Dixie at Atlanta's Waverly Hotel. SCLC is boycotting Winn-Dixie for buying and selling products from South Africa, not using Black and women-owned businesses and not equitably reinvesting in the Black community. Picketing and demonstrations have escalated in several states with the arrests of elected officials, labor leaders, clergy, professors, students and others joining SCLC President Dr. Joseph Lowery in support of the boycott.The Atlanta University Center Robert W. Woodruff Library acknowledges the generous support of the Joseph & Evelyn Lowery Institute for Justice and Human Rights, the Joseph Echols Lowery Irrevocable Trust, and other donors in supporting the processing and digitization of Morehouse College's Joseph Echols and Evelyn Gibson Lowery Collection
Sound Strategies for Safe Driving:Exploring Auditory Interventions to Counteract Passive Driver Fatigue
Full text linkCognitive underload may lead to passive driver fatigue in long, repetitive driving scenarios. While secondary tasks facilitated by in-car voice assistants can act as stimulants, they may distract drivers if not properly designed. Our study examined a range of auditory interventions, e.g., listening to Music or Interactive Story Games, intended to boost driver arousal without compromising driving capabilities. Using EEG and EDA to measure physiological responses and driving performance metrics, we assessed the effectiveness of these auditory tasks. The study also examined the impact of varying levels of driver participation (vocal, physical, or passive) with these interventions. Results showed music significantly boosts arousal with minimal impact on driving ability. Additionally, we found that vocal participation yields a more favourable balance between arousal and deterioration in driving performance compared to passive listening or physical participation. Finally, we discuss how these insights could enhance in-car voice assistants to alleviate passive driver fatigue
Predictive Interfaces to Support Maritime Search and Rescue Operations with Drone Swarms
No full textThis project is a continuation of a 9th semester project, where a multi-UAV interface was created to assist in maritime search and rescue efforts. As the current search process of people in waterways is slow and expensive, an alternative process is presented where the search helicopter is replaced by a swarm of UAVs, reducing the search time and cost.Existing interfaces and research in the field are analyzed, and their findings suggest that predictive elements can positively influence workload and situational awareness. This field is still in its infancy and therefore could benefit from research that attempts to develop interfaces to support emergency personnel and learn from the use of these interfaces to inform the design of more effective SAR technology.Our work focuses on the design of the interface including the information elements as well as predictive elements that might support the Operations Manager in their role. A demo system is implemented as well to simulate different rescue scenarios during the study.User studies were conducted on several experts in the field to evaluate the interface and the predictive elements. Users preferred having the predictive elements to assist them in drawing the search area, but the results suggest that none of the predictive elements were the best and could be further improved. Overall the experts were positive about the simulated scenarios and the interface. Feedback from the experts gave future work that should be considered in such interfaces.The findings concludes that further research should be conducted on predictive elements for SAR interfaces
Augmented reality "Root of Guilt": Responses to Human vs. Robotic NPCs.
No full textWhile the horror genre has been around for a long time it has mainly been focusing on characters with some sort of human resemblance. Specifically robots have had a very limited appearances in this genre. This paper investigates which of two models; a human and a robot, will inflict the most intimidation according to participants' own evaluations as well as biomarkers. The study presents a research platform which enables a site specific horror-like escape room experience in augmented reality developed for the HoloLens 2. The experience takes baseline in the horror game Root of Guilt of which some assets are reused.The experience is designed to be immersive and interactive in an unsettling environment in which the participants are exposed to the two characters. The results presented show that further data processing is necessary in order to gather viable results from the psychological measures. However according to participants' the human was deemed as the more intimidating of the two. Furthermore the escape room is evaluate as an intimidating yet enjoyable experience and the participants shows interest in more content
Improving CNC Processes Using Computer Vision to Digitise Physical Objects
No full textWhen working with CNC machines, there is sometimes a need to replicate an already existing object. In the upholstery industry it is normal to have handmade templates, thus there is no CAD file available to cut with a CNC machine. Recreating objects without the original file can be a difficult and time consuming process that involves tracing an object in a CAD program. Additionally, not all who works with CNC machines are necessarily apt at using CAD programs. We present CopyCut!, a system that allows users to copy existing objects or create new objects from sketches. CopyCut! extracts contours from images captured using a camera mounted above a CNC machine, and converts them into vector format, allowing users to use them in CAD programs or with the CNC machine. CopyCut! thus creates a new process for copying objects and allows for creative ways of using objects and sketches to create new products. CopyCut! differs from other similar work in that it allows much larger work area than those described in the related work, and does not use any specialised equipment. CopyCut! is a simple addition to an industrial CNC machine, meaning it can be set up and used without changing expensive equipment. We also describe several creative ways to use CopyCut! beyond copying of objects. To evaluate CopyCut! we tested the accuracy and conducted both an expert review and a co-design session. The system has an minimum accuracy error of 0.2 millimetres in the centre of the work area, but worse further away due to camera lens distortion. The expert review and co-design session gave us feedback on the usefulness of CopyCut! and possible improvements.<br/
From Zero to Drone Hero: Enhancing Critical Infrastructure Security with User-Centered Drone Interface Considerations
No full textThe security and safety of critical infrastructure is a critical concern for modern society. Threats to the infrastructure are becoming more sophisticated, traditional monitoring methods are becoming insufficient. Drones are becoming more prevalent and have emerged as a promising answer to the security and surveillance needs, by offering capabilities in rapid response and monitoring. However there has not been a lot of research into what the user wants from a system utilizing drones for security and surveillance, and how those needs translate to designing a user interface for such a system. The goal of this paper will be to find out what operations personnel want from a system using drones, and how an interface should be designed to support those wants. The context used in this paper, is the monitoring of a power plant facility. Here the drones are tasked with monitoring for intruders, and responding to alarms. Stakeholders with experience in being operations personnel and drones were brought on to provide a knowledge base that could be drawn from. This paper has resulted in several design suggestions for designers to use, and researchers to explore
Comparing Text-based Onboarding Methods for Virtual Reality Interactive Showcasing
No full textIn this comparative study, we evaluated the impact of twotext-based onboarding methods - contextual tooltips andtraditional tutorial screens - on usability and system satisfac-tion within a virtual reality (VR) interactive showcasing. Themethods were tested on an interactive showcase prototypefor an industrial robotics product, ACOPOS 6D. The study re-vealed that the contextual tooltip method yielded higher sys-tem satisfaction as participants felt less rushed and frustratedand demonstrated improved task performance. However, thetwo methods had no significant difference in perceived us-ability, learnability, or task completion time. These findingscontribute to the ongoing discussion about the best practicesfor onboarding methods in VR interactive showcases. Fur-ther research is needed to improve onboarding intuitivenessand adaptability to the system’s complexity
