Item Artifacts and Artifaction: Two Years of Historical Preservation with Benj. Harrison Presidential Site(2022) Wood, Zebulun M.; Sunderlin, Rob; Johnson, Jennifer; Hyde, CharlesIn 2016, the Benjamin Harrison Presidential Site, based out of Indianapolis, contracted our class N420 Project Development to produce a virtual museum to become known as The 23rd Floor. Virtual reality systems allow interaction with 3D replicas of artifacts that are normally not able to be displayed due to quantity of historical artifacts and insufficient space to display them in. The University Library's Center for Digital Scholarship was instrumental to providing digital scans that provided the foundation to recreate authentic replications of over 50 assets inside the growing virtual museum.Item Virtual Surgical Planning for Implant Supported Auricular Prosthetics: Three Scanning Techniques(2022) Bellicchi, T.; Ghoneima, A.; Wood, Z.; Jacobs, C.B.T.; Levon, J.The purpose of this poster is to determine the most efficient and accurate method for auricular scanning in implant-supported auricular prosthetics. Implant-supported auricular prosthetics are ideally suited for virtual surgical planning. Most patients have an intact contralateral ear that may be used to digitally model the missing ear due to cancer, trauma, or congenital defect. Imaging data may be acquired by a variety of 3-dimensional data acquisition methods. Once data is captured from the intact ear, it can be copied, mirrored, and placed in the appropriate position for virtual implant planning and surgical guide design.Item Facial Scanning, Digital Sculpting, Stereolithographic Rapid Prototyping: Auricular, Orbital, and Nasal Prosthetic Case Reports(2022) Bellicchi, T.; Jacobs, C.B.T.; Wood, Z.M.; Ghoneima, A.; Diaz-Rubayo, D.; Alderson, N.; Levon, J.; Morton, D.This poster presents a digital workflow for three maxillofacial prosthetic patients. The goal of this poster is to demonstrate the use of facial surface imaging, computer-aided design, and rapid prototyping resin molds for fabrication of silicone facial prosthetics. Pre-surgical scan data and contralateral anatomy informs prosthetic design. A workflow for immediate prosthetic rehabilitation involving intraoperative facial scanning at the time of tumor resection is presented.Item Mandibulectomy Prosthetic Case Report: Comparisson of Traditional and Digital Fabrication Methods with 3DMD Face Scanning, Digital Sculpting, and 3-Dimensional Printing(2022) Bellichi, Travis; Jacobs, Cade B.T.; Wood, Zebulun M.; Al-Qahtani, Nasser; Alderson, Nicole; Rogers, Jeff; Haug, Stephen P.; Levon, John A.Maxillofacial silicone elastomer prostheses are used to replace facial features congenitally absent, surgically removed due to disease, or lost because of trauma. Traditional prosthetic fabrication (impression, wax-up, mold fabrication, and silicone processing) can be streamlined using digital scanning, and computer-assisted design and manufacturing. The purpose of this report is to improve traditional facial prosthetic workflow using facial scanning, digital prosthetic design, and 3-dimensional printing technology. In this clinical case report, we present two design and fabrication protocols for mandibulectomy prosthesis: traditional versus digital modeling and 3D printing.Item 3D Printed Cast and Interim Obturator for Maxillectomy with Pedicled Buccal Fat Pad Flap(2022) Bellicchi, T.; Jacobs, C.B.T.; Wood, Z.M.; Ghoneima, A.; Levon, J.; Morton, D.This poster presents a hybrid workflow using intra-oral digital scanning, 30 printing, Biocryl vacuform matrix, and soft denture reline material to obturate a partiallyhealed pedicled buccal fat pad flap maxillectomy. The goal of this poster is to demonstrate an effective workflow for interim obturation with recent post-surgical reconstruction patients unable to tolerate traditional intraoral impression techniques and materials.Item Virtual Reality to Assess and Treat Childhood Aggression(2022) Mineart, Riley; Wood, Zebulun M.; Hummer, TomThe lack of advancement within the existing forms of assessment and treatment for youth aggression result in inaccurate data. The potential of advancement needs to be addressed, as accurate assessments of aggressive behavior lead to affective treatment. The integration of virtual reality will help fill the gap between clinical treatment and the real environments in which aggressive behaviors occur. I have developed a paradigm with the long-term goal of improving the efficiency and accuracy of assessments and treatments. The capabilities of virtual reality are limitless, and will provide positive long-term affects on youth aggression. The long-term goals will build on this to address the existing problems.Item Taking Stock of the Present and Future of Smart Technologies for Older Adults and Caregivers(2021) Harrington, Christina N.; Jelen, Ben; Lazar, Amanda; Martin-Hammond, Aqueasha; Pradhan, Alisha; Reeder, Blaine; Siek, Katie; Human-Centered Computing, School of Informatics and ComputingItem Daughters of Men: Saudi Women's Sociotechnical Agency Practices in Addressing Domestic Abuse(Association of Computing Engineering, 2020-12) Rabaan, Hawra; Young, Alyson L.; Dombrowski, Lynn; Human-Centered Computing, School of Informatics and ComputingWhile domestic abuse is an all too common experience for women worldwide, how people experience the abuse and their resources to deal with the abuse differ. In this qualitative, interview-based study, we examine Saudi women's domestic safety concerns living in Saudi Arabia and the United States. Based on non-Western Islamic feminist views of agency, we identify three key practices, focused on how women resist or deal with their domestic violence. For each practice, we highlight how interwoven cultural, religious, and political contexts impact Saudi women's ability to recognize and deal with domestic abuse. We attend to technology's role in enabling or hindering women's agency. These practices include: 1) recognizing abuse, where women identify abusive situations, 2) managing abuse, where women find ways to cope with ongoing or anticipated abuse within their constraints and resources, and 3) seeking non-abusive futures, where women decide how to mitigate the abuse or leave their abuser. Given domestic violence's complicated nature, we highlight several key design recommendations based on women's values.Item E Pluribus Unum: Using Conceptual Metaphor Theory to Explore and Support Mixed-Ability Workplaces(ACM, 2021-10) Cafaro, Francesco; Brady, Erin; Chandra, Sow Mya; Patil, Ulka; Saxena, Abhijeet; Human-Centered Computing, School of Informatics and ComputingEven when they are able to secure employment, people with cognitive disabilities typically encounter significant difficulties in the workplace. In this paper, we focus on Mixed-Ability workplaces: work settings in which people without disabilities and with different types of disabilities collaborate on a daily basis. The case study for our exploratory research is a university library that has been able to support a mixed-ability work setting for over four years. We describe how a theory from cognitive linguistics (Conceptual Metaphor Theory) can be used to explore the challenges that people encounter in mixed-ability workplaces, identify the cognitive processes that differ between neurotypical team leaders and workers with cognitive disabilities, and translate these findings into design recommendations for embodied technologies that support mixed-ability workplaces.Item Show Me How You Interact, I Will Tell You What You Think: Exploring the Effect of the Interaction Style on Users’ Sensemaking about Correlation and Causation in Data(ACM, 2021-06) Alhakamy, A'aeshah; Trajkova, Milka; Cafaro, Francesco; Human-Centered Computing, School of Informatics and ComputingFindings from embodied cognition suggest that our whole body (not just our eyes) plays an important role in how we make sense of data when we interact with data visualizations. In this paper, we present the results of a study that explores how different designs of the ”interaction” (with a data visualization) alter the way in which people report and discuss correlation and causation in data. We conducted a lab study with two experimental conditions: Full body (participants interacted with a 65” display showing geo-referenced data using gestures and body movements); and, Gamepad (people used a joypad to control the system). Participants tended to agree less with statements that portray correlation and causation in data after using the Gamepad system. Additionally, discourse analysis based on Conceptual Metaphor Theory revealed that users made fewer remarks based on FORCE schemata in Gamepad than in Full-Body.
