Drivers use nonverbal cues such as vehicle speed, eye gaze, and hand gestures to communicate awareness intent pedestrians. Conversely, in autonomous vehicles, drivers can be distracted or absent, leaving pedestrians infer from the alone. In this paper, we investigate usefulness of interfaces (beyond movement) that explicitly vehicles pedestrians, focusing on crosswalk scenarios. We conducted a preliminary study gain insight designing Based outcomes, developed four prototype deployed them...

AV-pedestrian interaction will impact pedestrian safety, etiquette, and overall acceptance of AV technology. Evaluating is challenging given limited availability AVs safety concerns. These challenges are compounded by "mixed traffic" conditions: studying be difficult in traffic consisting vehicles varying autonomy level. We propose immersive simulators as design tools to study interaction, allowing rapid prototyping evaluation future interfaces. present OnFoot: a VR-based simulator that...

People employ expressive behaviors to effectively communicate and coordinate their actions with others, such as nodding acknowledge a person glancing at them or saying "excuse me" pass people in busy corridor. We would like robots also demonstrate human-robot interaction. Prior work proposes rule-based methods that struggle scale new communication modalities social situations, while data-driven require specialized datasets for each situation the robot is used in. propose leverage rich...

Autonomous vehicles (AVs) will redefine interactions between road users. Presently, cyclists and drivers communicate through implicit cues (vehicle motion) explicit but imprecise signals (hand gestures, horns). Future AVs could consistently awareness intent other feedback to based on their sensor data. We present an exploration of AV-cyclist interaction, starting with preliminary design studies which informed the implementation immersive VR simulator, evaluation a number interfaces. Our...

Current vehicle-pedestrian interactions involve the vehicle communicating cues through its physical movement and nonverbal from driver. Our work studies at a crosswalk in presence of autonomous vehicles (without driver) facilitated by deployment interfaces intended to replace missing driver cues. We created four prototype based on different modalities (such as visual, auditory, physical) locations (on vehicle, street infrastructure, pedestrian, or combination pedestrian). findings two user...

Live and pre-recorded video tutorials are an effective means for teaching physical skills such as cooking or prototyping electronics. A dedicated cameraperson following instructor's activities can improve production quality. However, instructors who do not have access to a cameraperson's help often work within the constraints of static cameras. We present Stargazer, novel approach assisting with tutorial content creation camera robot that autonomously tracks regions interest based on...

Voice assistants have afforded users rich interaction opportunities to access information and issue commands in a variety of contexts. However, some feel uneasy or creeped out by voice assistants, leading decreased desire use them. As there has yet be comprehensive understanding the factors that cause perceive as being creepy, this research developed an empirical scale measure creepiness inherent various assistants. Utilizing prior creation methodologies, 7-item Perceived Creepiness...

New immersive 3D design tools enable the creation of spatial recordings, capturing collaborative activities. By reviewing captured sessions, which include user activities, workflows, and tool use, users can reflect on their own processes, learn new understand others' rationale. However, finding interesting moments in activities be challenging: they contain multimodal data (such as motion logged events) occurring over time difficult to specify when searching, are typically distributed many...

In ad-hoc human-robot collaboration (HRC), humans and robots work on a task without pre-planning the robot's actions prior to execution; instead, allocation occurs in real-time. However, research has largely focused allocations that are pre-planned - there not been comprehensive exploration or evaluation of techniques where is adjusted Inspired by HCI territoriality proxemics, we propose design space novel including both explicit techniques, user maintains agency, implicit efficiency...

Remote teleoperation is an important robot control method when they cannot operate fully autonomously. Yet, presents challenges to effective and full utilization: controls are cumbersome, inefficient, the teleoperator needs actively attend its environment. Inspired by end-user programming, we propose a new interaction paradigm support for combinations of repetitive complex movements. We introduce Mimic, system that allows teleoperators demonstrate save trajectories as templates, re-use them...

Haptic feedback enhances collision avoidance by providing directional obstacle information to operators in unmanned aerial vehicle (UAV) teleoperation. However, such is often rendered via haptic joysticks, which are unfamiliar UAV and limited single-directional force feedback. Additionally, the direct coupling of input device method diminishes operators' control authority causes oscillatory movements. To overcome these limitations, we propose AeroHaptix, a wearable system that uses...

Maintaining the safety of humans is paramount concern in field human-robot interaction. We employed a Research through Design (RtD) approach to explore better HRI mechanisms. conducted preliminary design study where we presented group designers various scenarios different robotic platforms acting unsafely. Our findings indicate that participants mapped human responses unsafe interfaces, natural defensive behaviors response varying levels threat stimuli. Based on findings, suggest leveraging...

Over the past few years, IT landscape has changed dramatically to facilitate new entrants from emerging economies in global market. Some nations such as India and China are poised emerge superpowers years come. In this paper, we attempt analyze some of critical success factors (CSF) that development leaders. Taking an example, explore CSFs like educational system, governmental policies, infrastructure entrepreneurial activities necessary for creating fostering We conclude by describing best...
