I research user needs to design resilient systems and accessible products to serve the community.

Our Process:

User Needs & Interviews
I led the foundational research to define specific accessibility challenges, combining structured interviews with direct gameplay observation.From this interview, the pain points identified were:
- There are limited options for secondary controllers that work with Nintendo Switch.
- Buttons and joysticks are too small and difficult to use.
- Standard controllers move and shift around when being used placed on the table.
- Multiple button combinations and repeated pressing of buttons are difficult.
- User has more mobility in right arm than left, putting more strain on the right arm.Competitive Analysis:
To better understand the currently available options for users, I completed a competitive analysis:Sony’s Access Controller: A circular, modular design enabling single-handed access to multiple controls. It features re-mappable inputs and adjustable add-ons, allowing users to customize the layout to their physical needs.Xbox’s Adaptive Controller: A centralized hub featuring large, tactile buttons designed for effortless activation. It utilizes an anti-slip base with Velcro integration to ensure secure, modular mounting across various setups.I discovered that both products contained different supportive features that the user needed. However, they were available on separate products. Furthermore, other pain points were still missing such as the integration needed for Switch usage. To minimize costs, we decided to integrate the user's purchased Access Controller as part of the product.

The Engineering ProcessFeasibility & Selection: While the team explored broad concepts via "Crazy 8s," we conducted a technical feasibility analysis with professors that identified the modular controller as the only solution viable for the 10-day sprint constraint.Hardware Engineering: I supported in customizing the software and testing for the the plug-and-play programmable HID Remapper for the Nintendo Switch. Furthermore, I helped in soldering standard 3.5mm jacks to modified low-force joystick modules and assembling the custom switch wiring.3D Printing & Assembly: I led the component sourcing phase to identify viable open-source assistive geometries. I then managed the digital fabrication workflow, optimizing slicing parameters and print settings to ensure the high-friction joystick covers and angle stand met the necessary durability and fit requirements.

Remappable Buttons: Large and low-force switches accommodating limited finger strength.Velcro Board: A mounting surface that allows the controller layout to adapt and prevents user's controller movement from usage.HID Remapper: Bridge hardware limitations between Switch and controller.Angle Adjustment Stand: Reduces wrist strain tilting controller to meet user's natural arm height.Wrist/Hand Cushion: Supports the wrist during play to lessen strain on the dominant right arm.Custom Joystick: Replaces standard joysticks with a larger grip and provides tactile feedback.

Reflections:
Working within a strictly time-boxed 10-day sprint taught me the value of "strategic sourcing." I learned that relying on a passionate community of engineers, designers, and creatives is often more important in building a working solution than "reinventing the wheel."By leveraging existing open-source firmware and standard hardware modules, I could focus my energy on the unique ergonomic needs of the user rather than basic connectivity. This experience solidified my belief that the best design solution is often the one that intelligently integrates existing technologies through collective global action. Design and technology are fields where everyone can contribute, which is why it is so important to have input from all places.

The Problem:
Data storage carries a massive physical cost. With over 50% of stored data classified as "digital waste" (redundant or obsolete files), global data centers consume an estimated 460 TWh of electricity annually while depleting community water supplies. Universities often inadvertently accumulate vast amounts of this digital data adding to the load on data centers. We asked: "How can we motivate users to declutter their digital footprint and build long-term sustainable habits?"The Design Solution: Digibyte leverages the "Ownership & Empowerment" model to turn file deletion into a positive habit. It provides a unified dashboard that aggregates physical and cloud storage, giving users a clear view of their 'digital footprint' to easily identify waste. We also replaced guilt with gratification. By translating technical metrics into relatable wins (e.g., "You saved 3 cups of coffee worth of energy"), users feel immediate agency over their environmental impact.

Design RationaleThe core architecture of Digibyte is grounded in Hungerford’s Behavior Flow Chart, moving users from passive storage to active, environmentally responsible ownership.Building "Ownership" through Centralization: We tackle "digital hoarding" by centralizing fragmented data (Photos, Documents, Email, Apps) into a single source.“Empowerment” via Positive Reinforcement: To turn a chore into a habit, we focus on the Internal Locus of Control. Positive messaging after deletion tasks reinforces the behavior.Smart Automation & Autonomy: Features like the Attachment Manager, Smart Search, and Diggy reduce the cognitive load of finding "waste."

Solution Details: Selected interaction flow. GIF optimized for high-performance loading.

Behavioral Reinforcement: Integrated "Celebration" pop-ups to reward decluttering milestones and reinforce positive habits.Visual Storage Tracking: Files are categorized by type with progress bars that visualize space usage in real-time.Organized File Deletion: Files are easy to delete through the system categorizing and filtering files that are taking up unnecessary space. Users can double-check the selection before simply pressing delete. There are undo options built in for mistakes."Diggy" AI Assistant: A chatbot that automates complex decluttering tasks through simple conversational commands.Gamified Impact: Deleting files unlocks milestones that translate "megabytes saved" into tangible environmental wins, reinforcing positive habits.

Reflections:
I learned that for invisible problems like "digital waste," just designing for usability isn't enough. Design must provide tangible visualization to support the behavioral change needed for sustainable action. Furthermore, I realized that the design process is rarely linear. I learned that taking a strategic step backward is often necessary to ensure the final design truly meets the needs of the people we are designing for.
