Enhancing Human-Computer Interaction through Spatial Computing
Zhu Wang, postdoc at NYU

Location: Larrañaga Engineering Auditorium (Centennial 1041)
Abstract:
With the rise of the metaverse, we are in the midst of a revolutionary transition from traditional computing to spatial computing. Powered by technologies like AR/VR/XR, AI, and robotics, spatial computing represents the next leap toward creating a more capable, intuitive, and natural extension of human faculties. In the future, spatial computing will be as integral to daily life as smartphones are today, transforming the way we interact with digital content and the physical world. However, the interaction paradigms have not yet evolved to fully align with this technological shift. The current emphasis remains largely on immersive experiences through stereo displays, which only represent a fraction of what spatial computing has to offer. To explore its full potential, my research focuses on integrating spatial computing with emerging technologies, while aligning it with how we naturally perceive and engage with our physical and virtual environments. In this talk, I will present two key areas of my work:1. Innovating multisensory simulations for perception investigation, assessment and rehabilitation; 2. Designing novel intelligent assistants that leverage AI, robotics, and multimodal inputs to provide context-aware support. I will discuss how these innovations enable a more seamless integration of the digital and physical worlds, making spatial computing a true extension of our bodies and senses.

Which links matter most? Sparsifying epidemic models with effective resistance
Cris Moore, Professor at the Santa Fe Institute

Location: Larrañaga Engineering Auditorium (Centennial 1041)
Abstract:
Network science has increasingly become central to the field of epidemiology. However, many networks derived from modern datasets are not just large, but dense, with a high average degree. One way to reduce the computational cost of simulating epidemics on these networks is sparsification, where a subset of edges is selected and reweighted based on some measure of their importance. Following recent work in computer science, we find that the most accurate approach uses the effective resistances of edges, which can be computed from the graph Laplacian. The resulting sparse network preserves both the local and global behavior of the SIR (susceptible-infected-recovered) model, including the probability each node becomes infected and its distribution of arrival times. This holds even when the sparse network preserves less than 10% of the edges of a mobility network from the United States. Our work helps illuminate which links of a network are most important to disease spread. Defining edge importance using purely topological methods, or by thresholding edge weights, does not perform nearly as well.

Innovating Future HPC Systems: Seamless Integration, Evolving Architectures, and Advanced Simulation for Co-Design
Arun Rodrigues, Samsung Electronics Device Solutions
Wednesday, September 18, 2024, 2:00 PM
Location: Larrañaga Engineering Auditorium (Centennial 1041)
Abstract:
High-performance computing (HPC) systems have long been constrained by physical limitations, manufacturing challenges, and software requirements. As future systems evolve, they must address these issues with innovative technologies and architectures. Key advancements will involve seamless integration of heterogeneous processing elements, memory proximity to processors, and more cohesive network design. These improvements will be enabled by breakthroughs in packaging, fabrication, and signaling technologies. Simultaneously, programming and execution models must adapt to fully leverage these new architectures. Designing such systems will demand flexible, integrated simulation and modeling capabilities. Comprehensive frameworks will be essential to inform design choices, optimize trade-offs, and facilitate co-design across hardware, runtimes, operating systems, and application software.

Expectation vs Reality: Why do industry guidelines and certifications fail to ensure baseline security?
Sazzadur Rahaman, University of Arizona

Location: Centennial Engineering Center STAMM Room - please note the change of room as the auditorium is out of order.
Abstract:
Industry-wide baseline security directly impacts the associated risks in the business. Apart from that, it also has other significant societal impacts. To ensure such security baselines, various industries (i.e., the payment card industry) maintain security guidelines and specifications. For critical domains, adoptions are generally assured through a systematic compliance checking and certification process. However, such compliance evaluations are significantly hindered by several societal and technical roadblocks.
In this talk, I will discuss the challenges of security guideline adoption and industry-wide compliance checking in light of my experience in the payment card industry and IoT. Our study of e-commerce websites and payment apps revealed that there is a significant gap between the guidelines, their adoption by the practitioners, and compliance evaluation. To assess the baseline security of a less-regulated industry, we studied the IoT ecosystem guidelines and industry perspective towards their adoption. Our findings reveal that even the most comprehensive guidelines fall short, i.e., they do not cover security topics widely or deeply. Our usefulness evaluation shows that most guidelines alone will not succeed in preventing IoT-related security failures. The implication for developers is that a single guideline might not be sufficient for in-depth defense.

Location: Larrañaga Engineering Auditorium (Centennial 1041)
Abstract:
As we collectively build omnipresent sensor/actuator networks coupled with omniscient AI, what are the design approaches informed by the science of complexity to realize self-sovereign 'sousveillant" data architectures for self-governance and collective intelligence? I will demonstrate some of my work on Simtable.com, Realtime.Earth, AgentScript.org, and the research of RedfishGroup and the Harvard Visualization Lab that attempts to address this question and my 35-year journey in HCI, agent-based modeling, spatial augmented reality, and decentralized computing networks. I will make the case that New Mexico and research at UNM, LANL, Sandia, and Santa Fe Institute is uniquely suited to bring about a fundamental change in the architecture of the next era of collective computing.

A little light reading: changes in lighting technology and the human and environmental health
Tom Igoe, Arts Professor, NYU
Wednesday, February 28, 2024, 2:00 PM
Location: Larrañaga Engineering Auditorium (Centennial 1041)
Abstract:
The lighting industry has seen some significant changes in the past decade. There are four driving forces behind this:
- LEDs are the primary lighting technology now;
- Digital control of light is becoming increasingly common;
- Recent discoveries in biology have detailed light's impact on human health;
- The lighting industry has a material impact on the environment.
These factors change profoundly how we design, how we teach lighting design, how we make lighting fixtures. The first two affect what we can do with light; the second two affect what we should do with light. In this talk, I'll discuss these factors in context of the lighting industry and its intersection with digital systems and human and environmental health.

Abstracts:
Title: Interactive Murals
This work explores Interactive Murals; a mural that blends traditional mural practices and ubiquitous computing, which contains embedded electronics including sensors, actuators, and microcontrollers. I designed three interactive murals in collaboration with a professional muralist, Nanibah Chacon. We developed a suitable workflow for creating interactive murals. This workflow guided us in teaching middle and high school students a series of introductory workshops and interactive mural workshops. Nanibah and I designed and constructed two large outdoor interactive murals with students. After each project, I conducted semi-structured interviews with students, and I determined that students gain agency, learn technical skills, and positively shift their perspectives of computer science by designing and building interactive murals. This talk also each aspect of the workflow for the most recent interactive mural at the National Hispanic Cultural Center.
Title: Travel Reduction Algorithm
Travel Reduction Algorithm (TRAvel) Slicer is a slicing software that minimizes X, Y, and Z travel movements in 3D printing. Conventional slicing software often generates travel movements to print everything within each given layer. These travel movements can negatively impact the quality of prints, especially in models with branching structures. Moreover, for some printers and some materials, travel movements can make printing impossible. TRAvel Slicer combines Zhao et. al.’s method of space-filling Fermat spirals and introduces a method of vertical ordering in order to minimize travel movements in X, Y, and Z. I demonstrate how TRAvel Slicer increases efficiency of print time and makes it feasible to print complex models on Direct Write 3D printers in novel materials.
What is wrong with Artificial intelligence?
Manel Martínez-Ramón, UNM

Location: Larrañaga Engineering Auditorium (Centennial 1041)
Abstract:
The public opinion about AI bounces between the utopia, with the promise that AI will promote unseen productivity, and the dystopia, where society will collapse and fail. This last one raises fear, controversy, and lack of social acceptance. This makes it necessary to rebrand AI in an unapologetic way, to demonstrate its benefits to society through its incorporation as an engineering tool. There is a quest to construct a corpus of AI fundamentals, AI engineering and industrial and societal applications. In this talk we will review the present context of AI, its outstanding drawbacks from the societal point of view and avenues for a more optimistic future.
