Human-Centered AI: How Howard University is Pioneering a Future Where Tech Reduces, Not Adds, to Stress
Imagine a naval officer facing a critical decision in a high-pressure situation, instantly receiving clear, concise, augmented reality overlays highlighting the optimal course of action. This isn’t science fiction; it’s the direction of research spearheaded by Dr. Gloria Washington and the Human Centered Artificial Intelligence Institute (HCAI) at Howard University. As AI rapidly permeates every facet of life, a crucial question emerges: are we building technology that serves humanity, or are we simply automating existing biases and inefficiencies? HCAI is betting on the former, and their work is poised to redefine how we interact with AI, particularly in moments of intense stress.
The Rise of Human-Centered AI
Since 2022, Dr. Washington has championed an approach to AI development that prioritizes human needs and well-being. Funded by the Office of Naval Research (ONR), HCAI isn’t just building smarter algorithms; it’s building useful algorithms. This means collaborating with HBCUs, industry partners, and government agencies to ensure AI solutions are relevant, equitable, and accessible. A cornerstone of this approach is recognizing that AI’s potential is limited if it doesn’t account for the nuances of human communication and cognition.
This commitment is vividly illustrated by Project Elevate Black Voices, a Google-sponsored initiative led by Dr. Washington. The project has amassed over 600 hours of recorded African American dialects, aiming to improve the accuracy of automated speech recognition systems. As Washington explains, this isn’t simply about technical accuracy; it’s about ensuring that AI technologies are inclusive and don’t perpetuate existing societal biases. “We believe this will take us into a new realm,” she states, envisioning a future where AI understands and respects the diversity of human language.
Tackling Stressful Decision-Making with AI
Currently, HCAI’s research is focused on a particularly challenging application: improving tactical decision-making under high stress. The team is developing chatbots powered by large language models (LLMs) and integrating them with “extended reality” tools to assist naval officers in the field. This isn’t about replacing human judgment; it’s about augmenting it, providing crucial information at the point of need, and reducing cognitive overload.
Third-year doctoral student Christopher Watson, a software engineer and former educator, explains the core concept: “The tool is intended to help [make] decision making less burdensome.” The Tactical Decision-Making Under Stress (TADMUS) model utilizes retrieval-augmented generation, accessing military protocol documents to provide contextually relevant information and minimize “hallucinations” – instances where LLMs generate incorrect or nonsensical responses. This is paired with an augmented reality component, transforming text-based output into interactive displays using colors, icons, and other visual cues.
Overcoming Data Scarcity with Generative AI
A significant hurdle in developing TADMUS is the limited availability of real-world naval imagery. Confidentiality concerns restrict access to detailed images of active vessels, hindering the training of accurate models. Senior Research Scientist Saurav Aryal found a creative solution: leveraging generative AI to augment existing images. By flipping, zooming, and intelligently filling in backgrounds, Aryal’s team expanded a dataset of 100 images to over 1,000, significantly improving the model’s performance. This demonstrates the power of AI to overcome data limitations and accelerate innovation.
The Human Factor: Ensuring AI is a Tool, Not a Distraction
The technical sophistication of TADMUS is only half the battle. Ensuring the tool is genuinely helpful requires a deep understanding of human-computer interaction and the impact of stress on cognitive function. Senior Research Scientist Dr. Lucretia Williams is leading research into these areas, creating simulated environments – one calm, one stressful – to assess how users interact with the system under different conditions. Participants complete NASA Task-Load Index questionnaires and perceived stress scale assessments to provide valuable data on the model’s effectiveness.
Dr. Simone Smarr, focusing on applying the text-based model to augmented-reality tools, emphasizes the importance of intuitive design. “We’re trying to explore this different and more interactive way of displaying [information],” she explains, exploring wearable glasses like the Ray-Ban Meta glasses as potential delivery platforms. The challenge lies in striking a balance between providing sufficient information and avoiding overwhelming the user. “At what point is it that this is just too much stuff going on?” Smarr asks, highlighting the critical need for user-centered design principles.
Beyond the Battlefield: The Broad Applications of Human-Centered AI
While initially focused on naval missions, the potential applications of HCAI’s research extend far beyond the military. From medical emergencies and disaster response to everyday scenarios like driving – as Dr. Jaye Nias points out – the ability to make better decisions under pressure is universally valuable. Aryal envisions his image augmentation techniques being applied to fields like astronomy and satellite image analysis, where data scarcity is a common challenge. Williams, meanwhile, sees opportunities to leverage the simulation tests to evaluate the effectiveness of AI-powered educational tools.
HCAI is also playing a vital role in workforce development, training the next generation of AI scientists and engineers. Under Dr. Washington’s leadership, Howard University is solidifying its position as a leader in tech, ensuring that future innovators are equipped with the skills and knowledge to build AI systems that truly benefit humanity. “We’re studying how our unique way of mentorship and teaching of young scientists are creating a new workforce for occupying these future technical jobs,” Washington states.
The work at Howard University’s HCAI isn’t just about building better AI; it’s about building a better future – one where technology empowers us to navigate complexity, reduce stress, and make more informed decisions, ultimately enhancing the human experience.
