TeleAdvisor is a novel solution designed to support remote assistance tasks in many real-world scenarios. It consists of video camera and small projector mounted at the end tele-operated robotic arm. This enables helper view interact with workers' workspace, while controlling point view. also provides worker hands-free transportable device be placed anywhere his or her environment. Active tracking projection space used order reliably correlate between camera's space.

Infographics are engaging visual representations that tell an informative story using a fusion of data and graphical elements. The large variety infographic design poses challenge for their high-level analysis. We use the concept Visual Information Flow (VIF), which is underlying semantic structure links elements to convey information user. To explore VIF, we collected repository over 13K infographics. deep neural network identify related information, agnostic various artistic appearances....

Autonomous vehicle (AV) technologies are rapidly evolving with the vision of having self-driving cars moving safely no human input. However, it is clear that at least in near and foreseeable future, AVs will not be able to resolve all road incidents some situations remote assistance required. driving trivial introduces many challenges stemming mostly from physical disconnect operator. In order highlight these understand how better design AV teleoperation interfaces, we conducted several...

A composite indicator (CI) is a measuring and benchmark tool used to capture multi-dimensional concepts, such as Information Communication Technology (ICT) usage. Individual indicators are selected combined reflect phenomena being measured. Visualization of recommended enable interested stakeholders, well the public audience, better understand components evolution over time. However, existing CI visualizations introduce variety solutions there lack in CI's visualization guidelines. Radial...

Autonomous vehicles (AVs) are rapidly evolving as an innovative mode of transportation. However, the consensus in both industry and academia is that AVs cannot independently resolve all traffic scenarios. Consequently, need for remote human assistance becomes clear. To enable widespread integration on public roadways, it imperative to develop novel models operation. One such model tele-assistance, which promotes delegating low-level maneuvers automation through high-level directives. Our...

We present a study aimed to better understand users' perceptions of foot gestures employed on horizontal surface. applied user elicitation methodology, in which participants were asked suggest actions (referents) three conditions: standing up front large display, sitting down desktop and projected Based majority count agreement scores, we identified gesture sets, one for each condition. Each set shows mapping between common action its chosen gesture. As further contribution, new measure...

In this paper, we explore the practice of using a whiteboard for multiple tasks, and specifically how users employ whiteboards to smoothly transition between related sets tasks. Our study underscores several basic, but important affordances that support practice, including visual persistence, flexibility interaction primitives, their situated physicality. We discuss implications these findings design large display applications.

In this paper we investigate user performance and behavior, related to the issue of who controls point view in a remote assistance scenario. We describe an experiment that examined users completing two different tasks with aid gesturing device under conditions: when control camera was hands helper, it worker. Results indicate general, most knowledge is preferable leave helper. However, these results may depend on situation task at hand.

Augmented reality (AR) technology has the potential to enrich our daily lives in many aspects. One of them is museum visit experience. Nowadays, state art mobile visitor guides provide us with rich personalized, context aware information. However, these systems have one major drawback -- they force hold guide and look at its screen. The utilization smart-glasses allows providing a wearable AR display without necessity it distracting user from real object. This paper describes initial steps...

Museums are both appealing and challenging as an environment for indoor positioning research. By nature, they dense rich in objects information, a result contain more information than visitor can absorb time-limited visit. Many research projects have explored the potential of novel technologies to support delivery museum visitors. Having accurate position is key factor success such projects. In spite numerous experimented with, there no prevailing technology. Each technology has its benefits...

Novel collaborative technologies afford new modes of behavior, which are often not regulated by established social norms. In particular, shared augmented reality (AR) - where multiple users can create, attach, and interact with the same virtual elements embedded into physical environment has potential to interrupt current norms behavior. The objective our study is shed light on ways in AR challenges existing behavioral expectations. Using a simulated lab experimental design, we performed...

Autonomous vehicles (AVs) are rapidly evolving as a novel way of transportation. Nevertheless, there is consensus that AVs cannot address all traffic scenarios independently. Consequently, arises need for remote human intervention. To pave the large-scale deployment onto public roadways, innovative models operation must evolve. Such paradigm Tele-assistance, which posits low-level control should be delegated through high-level commands. Our work explores how such command language constructed...

Cultural heritage is an area that has recently drawn research attention, especially for exploring ways to harness novel mobile technologies supporting visitors. The main benefit of these their ability provide personalized, context-aware information services users. However, the use context-awareness connected a fundamental issue proactiveness – should system keep user in control all time and only respond requests, or take initiative propose its when needed? Proactiveness visitors' guides...

We present a novel system for browsing through very large set of images according to similarity. The are dynamically placed on 2D canvas next their nearest neighbors in high-dimensional feature space. layout and choice is generated on-the-fly during user interaction, reflecting the user's navigation tendencies interests. This intuitive solution image provides continuous experience navigating an infinite grid arranged by In contrast common multidimensional embedding methods, our does not...

One of the fundamental tasks in visualization is to compare two or more visual elements. However, it often difficult visually differentiate graphical elements encoding a small difference value, such as heights similar bars bar chart angles sections pie chart. Perceptual laws can be used order model when and how we perceive this difference. In work, perception Just Noticeable Differences (JNDs), minimum attributes that allow faithfully comparing elements, charts. Specifically, explore...

(1) Background: Mobile phone use during gait is associated with adverse health outcomes, namely increased risk of pedestrian injury. Healthy individuals can voluntarily prioritize concurrent task performance, but the factors underlying impact walking remain largely unknown. Thus, objective this work was to evaluate relationship between subjective (perceived) prioritization, cognitive flexibility and dual-task performance when using a mobile walking. (2) Methods: Thirty young participants...

We introduce MultiPresenter, a novel presentation system designed to work on very large display spaces (multiple displays or physically high-resolution displays). MultiPresenter allows presenters organize and present pre-made dynamic presentations that take advantage of space accessed from personal laptop. Presenters can use the extra provide long-term persistency information audience. Our design deliberately separates content generation (authoring) content. focus supporting flow variety...
