For students with visual impairments (VI), the possibility of a future in astronomy, or any science, technology, engineering, and mathematics (STEM) field, seems daunting. In order to bolster astronomy and STEM opportunities for high school students with VI in the United States, we developed the STEM Career Exploration Lab (CEL). Our STEM CEL methodology employs tactile astronomy instruction via 3D printing technologies and unique 3D-printed models, professionals with VI acting as role models, and partnerships with local STEM industries that provide insights into possible career paths. In partnership with the South Carolina Commission for the Blind (SCCB) and the Michigan Bureau of Services for Blind Persons (MBSBP), to date we have held four weeklong CELs (June 2017, June & July 2018, August 2019) and a 3D printer build workshop (September 2018), thus far serving about fifty students with VI. We have also held one professional development workshop for teachers of the visually impaired at the Maryland School for the Blind in October 2021. We gathered pre- and post-intervention data via student surveys, assessments of students' astronomy knowledge, and video recordings of the CEL activities in order to study to what extent the CEL model can enhance the students' attitudes towards, interests in, and capacities to participate in astronomy and STEM careers. Once fully tested and refined, we will make our 3D model files and activities freely available for further use and study. This work serves as a testbed for an expanded CEL program aimed at helping increase the representation of persons with VI in astronomy and STEM fields. This work is supported by a generous Innovative Technology Experiences for Students and Teachers (ITEST) grant from the National Science Foundation.

A Demonstration of Molder: An Accessible Design Tool for Tactile Maps
Tactile maps are important tools for people with visual impairments (VIs). Teachers and orientation and mobility (O&M) specialists often design tactile maps to help their VI students and clients learn about geographic areas. To design these maps, a designer must use modeling software applications, which require professional training and rely on visual feedback. However, most teachers and O&M specialists do not have professional modeling skills, and many have visual impairments. The complexity and inaccessibility of current modeling tools thus become major barriers for TVIs and O&M specialists when designing tactile maps. We present Molder, an accessible design tool for tactile maps. A designer creates a draft map model using Molder and prints the model. Then, she uses Molder to modify the draft model by directly interacting with it. Molder provides auditory feedback and high-contrast visuals to assist the designer in the design process.

Students with visual impairments struggle to learn various concepts in the academic curriculum because diagrams, images, and other visual are not accessible to them. To address this, researchers have design interactive 3D printed models (I3Ms) that provide audio descriptions when a user touches components of a model. In prior work, I3Ms were designed on an ad hoc basis, and it is currently unknown what general guidelines produce effective I3M designs. To address this gap, we conducted two studies with Teachers of the Visually Impaired (TVIs). First, we led two design workshops with 35 TVIs, who modified sample models and added interactive elements to them. Second, we worked with three TVIs to design three I3Ms in an iterative instructional design process. At the end of this process, the TVIs used the I3Ms we designed to teach their students. We conclude that I3Ms should (1) have effective tactile features (e.g., distinctive patterns between components), (2) contain both auditory and visual content (e.g., explanatory animations), and (3) consider pedagogical methods (e.g., overview before details).more » « less

Teachers of the visually impaired (TVIs) regularly present tactile materials (tactile graphics, 3D models, and real objects) to students with vision impairments. Researchers have been increasingly interested in designing tools to support the use of tactile materials, but we still lack an in-depth understanding of how tactile materials are created and used in practice today. To address this gap, we conducted interviews with 21 TVIs and a 3-week diary study with eight of them. We found that tactile materials were regularly used for academic as well as non-academic concepts like tactile literacy, motor ability, and spatial awareness. Real objects and 3D models served as “stepping stones” to tactile graphics and our participants preferred to teach with 3D models, despite finding them difficult to create, obtain, and modify. Use of certain materials also carried social implications; participants selected materials that fostered student independence and allow classroom inclusion. We contribute design considerations, encouraging future work on tactile materials to enable student and TVI co-creation, facilitate rapid prototyping, and promote movement and spatial awareness. To support future research in this area, our paper provides a fundamental understanding of current practices. We bridge these practices to established pedagogical approaches and highlight opportunities for growth regarding this important genre of educational materials.more » « less

In an era of ubiquitous digital interfaces and systems, technology and design practitioners must address a range of ethical dilemmas surrounding the use of persuasive design techniques and how to balance shareholder and end-user needs [2], [5]. Similarly, the increasing user concerns about unethical products and services [1] is paralleling a rise in regulatory interests in enforcing ethical design and engineering practices among technology practitioners, surfacing a need for further support. Although various scholars have developed frameworks and methods to support practitioners in navigating these challenging contexts [3], [4], often, there is a lack of resonance between these generic methods and the situated ethical complexities facing the practitioner in their everyday work. In this project, we designed and implemented a three-hour cocreation workshop with designers, engineers, and technologists to support them to develop bespoke ethics-focused action plans that are resonant with the ethical challenges they face in their everyday practice. In developing the co-creation session, we sought to answer the following questions to empower practitioners: • How can we support practitioners in developing action plans to address ethical dilemmas in their everyday work? and • How can we empower designers to design more responsibly? Building on these questions as a guide, we employed Miro, a digital whiteboard platform, to develop the co-creation experience. The final c o-creation e xperience w as d esigned w ith the visual metaphor of a “house” with four floors and multiple rooms that allowed participants to complete different tasks per room, all aimed towards the overall goal of developing participants' own personalized action plan in an interactive and collaborative way. We invited participants to share their stories and ethical dilemmas to support their creation and iteration of a personal action plan that they could later use in their everyday work context. Across the six co-creation sessions we conducted, participants (n=26) gained a better understanding of the drivers for ethical action in the context of their everyday work and developed an action plan through the co-creation workshop that enabled them to constructively engage with ethical challenges in their professional context. At the end of the session, participants were provided the action plans they created to allow them to use it in their practice. Furthermore, the co-design workshops were designed such that practitioners could take them away (the house and session guide) and run them independently at their organization or another context to support their objectives. We describe the building and the activities conducted in each floor below and will provide a pictorial representation of the house with the different floors, rooms, and activities on the poster presentation. a) First floor-Welcome, Introduction, Reflection: The first floor of the virtual house was designed to allow participants to introduce themselves and to reflect on and discuss the ethical concerns they wished to resolve during the session. b) Second floor-Shopping for ethics-focused methods: The second floor of the virtual house was designed as a “shopping” space where participants selected from range of ethicsfocused building blocks that they wish to potentially adapt or incorporate into their own action plan. They were also allowed to introduce their own methods or tools. c) Third floor-DIY Workspace: The third floor was designed as a DIY workspace to allow the participants to work in small groups to develop their own bespoke action plan based on building blocks they have gathered from their shopping trip and by using any other components they wish. The goal here was to support participants in developing methods and action plans that were resonant with their situated ethical complexities. d) Fourth floor-Gallery Space: The fourth floor was designed as a gallery to allow participants to share and discuss their action plans with other participants and to identify how their action plans could impact their future practice or educational experiences. Participants were also provided an opportunity at this stage to reflect on their experience participating in the session and provide feedback on opportunities for future improvement.more » « less

We introduce a novel vision-and-language navigation (VLN) task of learning to provide real-time guidance to a blind follower situated in complex dynamic navigation scenarios. Towards exploring real-time information needs and fundamental challenges in our novel modeling task, we first collect a multi-modal real-world benchmark with in-situ Orientation and Mobility (O&M) instructional guidance. Subsequently, we leverage the real-world study to inform the design of a larger-scale simulation benchmark, thus enabling comprehensive analysis of limitations in current VLN models. Motivated by how sighted O&M guides seamlessly and safely support the awareness of individuals with visual impairments when collaborating on navigation tasks, we present ASSISTER, an imitation-learned agent that can embody such effective guidance. The proposed assistive VLN agent is conditioned on navigational goals and commands for generating instructional sentences that are coherent with the surrounding visual scene, while also carefully accounting for the immediate assistive navigation task. Altogether, our introduced evaluation and training framework takes a step towards scalable development of the next generation of seamless, human-like assistive agents.more » « less
