XR based SOS system for construction workers
OVERVIEW Construction workers often cannot call for help when they are in the accident because of physcially immoble and noisy on-site environment. To address this, I designed and developed and XR based SOS system on Microsoft HoloLens 2 that allow workers request resque through eye gazing controll or automatically emergency request with head-mounted motion sensors. This system implemented with an intuitive interface tailored to workers’ XR literacy. User testing and simulated scenarios demonstrated reliable detection and increased worker trust, and the system was later presented at an international HCI conference and graduation exhibition, receiving strong recognition for its practical real-world potential.

OVERVIEW
As AI becomes deeply embedded in workplace tools, it is transforming how we work, make decisions, and create. However, through a user survey, I identified growing concerns among employees regarding data privacy, reliability, and the erosion of human cognitive and decision-making abilities. In response, I designed Co-AI Workplace SaaS—an enterprise platform that integrates AI while prioritizing data transparency, user autonomy, and productivity empowerment. User evaluations showed that transparent data feedback and a human-in-the-loop system foster trust, confidence, and critical thinking, demonstrating how Co-AI amplifies human capability rather than replacing it.

Behavior-Aware, Context-Informed Urban Service Design
OVERVIEW
Cities are advancing toward smart infrastructure, yet park waste management remains inefficient due to poor bin placement, low recycling awareness, and subjective design decisions. Field research revealed that effective solutions require understanding the interplay of behavior, space, and operations. This project proposes a smart trash can IoT system and a Case-Based Reasoning model that analyzes user behavior data to recommend context-aware interventions. Implemented with Python similarity algorithms and structured case inputs, the system generates transparent urban service exprience design suggestions.

OVERVIEW
As many older adults face social isolation, I aimed to provide them with an accessible way to re-engage socially. Through user studies, I found that low digital literacy makes online volunteer platforms difficult for them to use. To address this, I designed a voice-based AI assistant that recommends volunteer opportunities and guides users through each step with slow-paced, polite, and respectful dialogue tailored to their cognitive and emotional characteristics. User testing showed increased confidence in using technology and greater motivation to participate in social activities. This project demonstrated the impact of empathetic, dignity-centered AI for elderly users.

EV Charging Station UX Guideline Guidelines for EV Charger Installation at Humax Mobility
OVERVIEW
As a CX researcher at Humax Mobility, I found that many EV public charging stations were installed and designed without considering anthropometrics, interaction reach, or visibility—revealing a fundamental accessibility gap. In response, I developed a data-driven UX guideline that integrates reachability, gaze distance, gaze height, safety clearance, and realistic parking dimensions tailored to Korean EV users. Using national human-scale datasets and on-site measurements, I translated these insights into actionable spatial design criteria. This guideline improves accessibility, safety, and user experience, providing a scalable research-to-policy model for EV charging infrastructure.
OVERVIEW
As micro-mobility becomes more widespread, riders frequently stop or glance at their smartphones to check directions—a behavior that remains dangerous even when the device is mounted. The On Road haptic navigation form factor proposes an intuitive interface that minimizes visual load and leverages tactile cues to guide riders safely. By reducing visual dependency during navigation, this haptic form factor enhances riding safety, improves situational awareness, and supports more sustainable human–mobility interactions in urban environments.

OVERVIEW
People rely heavily on vision, limiting their ability to use other senses as sources of creative inspiration. This led me to explore whether a synesthetic, tactile-to-auditory experience could stimulate imagination in the absence of visual cues. Through public interviews in which participants were asked to guess various tactile sounds, I found that people naturally infer situational context and describe the sounds with vivid, unexpected sensory imagery. This revealed how multisensory engagement can unlock latent imagination and enhance creativity. In response, I desinged Ping-Pong, a synesthetic (tactile-to-auditory) tool that transforms everyday tactile experiences into sound, enabling users to interpret, imagine, and generate new creative associations. This work points toward new possibilities for future multisensory interface design.

OVERVIEW
Severe food insecurity in the Democratic Republic of Congo persists despite abundant natural resources, with most small family farmers lacking access to quality seeds, tools, and basic agricultural knowledge. Research revealed that low literacy, scarce educational infrastructure, and limited farming equipment prevent farmers from achieving self-sufficiency. To address this, I designed AutBon, a sustainable corn farming package that enables low-literacy users to independently cultivate high-yield corn. The kit includes seeds, tools, and fully visual, text-free farming instructions that can be understood without formal education. Its packaging system transforms into a reusable bag and work surface, maximizing utility in resource-limited environments. This project demonstrated how culturally grounded, visually driven UX design can empower marginalized communities and was internationally recognized with the 2021 iF Design Award.
