Distributed laboratories are environments where scientists and engineers working in geographically separated locations share access to interactive visualization tools and large-scale simulation computations, share information generated by such instruments, and collaborate across time and space to evaluate and discuss their results. The intent is to permit scientists, engineers, and managers at geographically distinct locations including individuals telecommuting from home to combine their expertise in solving shared problems by allowing them to simultaneously view, interact with, and steer sophisticated computation instruments executing on high performance distributed platforms. This paper reports on research e orts being undertaken at Georgia Tech that address the topic of distributed laboratories:Steering and monitoring tools and infrastructure used in the online observation and manipulation of two scienti c computations developed jointly with end users. Middleware to transport the on-line monitoring and steering events. Can be changed dynamically to adjust event streams to current system loads and monitoring steering needs. Visualization support to permit the de nition of appropriate visual abstractions and the e cient representation on 2D and 3D graphical displays. Collaboration infrastructure and abstractions.

Working dogs have improved the lives of thousands of people. However, communication between human and canine partners is currently limited. The main goal of the FIDO project is to research fundamental aspects of wearable technologies to support communication between working dogs and their handlers. In this pilot study, the FIDO team investigated on-body interfaces for assistance dogs in the form of wearable technology integrated into assistance dog vests. We created four different sensors that dogs could activate (based on biting, tugging, and nose gestures) and tested them on-body with three assistancetrained dogs. We were able to demonstrate that it is possible to create wearable sensors that dogs can reliably activate on command.

Accessibility of assistive consumer devices is an emerging research area with potential to benefit both users with and without visual impairments. In this article, we discuss the research and evaluation of using a tactile button interface to control an iOS device's native VoiceOver Gesture navigations (Apple Accessibility, 2014). This research effort identified potential safety and accessibility issues for users trying to interact and control their touchscreen mobile iOS devices while traveling independently. Furthermore, this article discusses the participatory design process in creating a solution that aims to solve issues in utilizing a tactile button interface in a novel device. The overall goal of this study is to enable visually impaired white cane users to access their mobile iOS device's capabilities navigation aids more safely and efficiently on the go.

When participants share data to a central entity, those who have taken on the responsibility of accepting the data and handling its management may also have control of decisions about the data, including its use, re‐use, accessibility, and more. Such concentrated control of data is often a default practice across many forms of participatory sciences, which can be extractive in some contexts and a way to protect participants in other contexts. To avoid extractive practices and related harms, projects can adopt structures so that those who make decisions about the data set and/or each datum are different from those responsible for executing the subsequent decisions about data management. We propose two alternative models for improving equity in data governance, each model representing a spectrum of options. With an individualized control model, each participant can place their data in a central repository while still retaining control of it, such as through simple opt‐in or opt‐out features or through blockchain technology. With a shared control model, representatives of salient participant groups, such as through participant advisory boards, collectively make decisions on behalf of their constituents. These equitable models are relevant to all participatory science systems, and particularly necessary in contexts where dominant‐culture institutions engage marginalized peoples.
