Clarifying Our Design Philosophy
Week 11 marked a moment of consolidation for ReNUSHU. Rather than expanding features or adding new mechanics, the team focused on clarifying how physical therapy movements should translate into gameplay—and, just as importantly, when they should not.
Through technical testing, advisor feedback, and close discussion with Conrad, we reached a clearer design philosophy that now guides the project forward.
Letting Go of Literal Mapping
Earlier iterations of the project attempted to directly map real-world physical therapy movements into in-game actions. While this approach felt conceptually honest, it consistently led to two problems:
- When movements were mapped 1:1, gameplay pacing suffered. Many PT exercises are slow, repetitive, and controlled—important qualities clinically, but difficult to translate into engaging moment-to-moment play.
- When gameplay was made more dynamic or expressive, the sensing technology could no longer support it reliably. Inconsistent detection led players to feel that their actions were not being recognized, creating frustration rather than motivation.
This tension became especially clear with step-up and tandem-walking concepts. Even when players performed the movements correctly, hardware limitations made accurate, repeatable detection difficult. Continuing to push these designs would have meant either punishing players for sensor error or encouraging unsafe movement patterns—neither of which aligned with our goals.
At this point, the team made a deliberate decision:
ReNUSHU would no longer pursue fully literal mappings between PT movement and game action.
Abstraction as a Design Commitment
Instead, Week 11 solidified our commitment to abstraction as a core design strategy.
Rather than asking the game to mirror every movement, we reframed PT exercises as reliable, repeatable inputs that advance a higher-level game state. This shift allowed us to:
- Respect the realities of sensing technology without hiding its limitations
- Avoid punishing players when detection is imperfect
- Preserve self-paced, clinically appropriate movement
- Focus gameplay rewards on consistency and completion rather than precision timing
Advisors and Conrad both emphasized that this approach better reflects real clinical values: successful rehabilitation is about doing enough of the right movement, safely and consistently—not reacting quickly or hitting exact spatial targets.
This reframing gave us a clearer answer to a recurring question:
What should the game reward?
Not raw motion accuracy, but sustained effort and successful completion.
The Balloon + Word Game as Philosophy in Practice
With this philosophy in place, the team finalized the direction of the third mini-game: the Balloon + Word Game.
In this design:
- Players perform seated leg raises, alternating left and right legs at a comfortable pace.
- Completing a PT-defined set inflates a balloon carrying a letter.
- After multiple balloons are earned, players use the letters to form a vocabulary word.
- Successfully forming a word triggers a clear, celebratory resolution as the balloons pop or float away.
This loop embodies our design philosophy:
- The physical movement remains clinically grounded and safe.
- The game layer is symbolic rather than literal.
- Cognitive challenge is light, flexible, and non-academic.
- Feedback emphasizes success without penalizing imperfect sensing.
Importantly, this structure allows therapists to adjust repetition counts, letter quantity, and word difficulty without redesigning the game itself—supporting customization while keeping the experience approachable.
Choosing Movements That Support the Philosophy
Alongside the gameplay decision, we also refined our thinking about which physical movements best fit this approach.
While step-up and step-down movements are functionally valuable, their detection proved unreliable and raised safety concerns when paired with screen-based interaction. In contrast, seated leg raises offer:
- More stable sensing characteristics
- Higher safety for users who may struggle with balance
- A natural rhythm for alternating left and right engagement
- Compatibility with symbolic, progress-based gameplay
This choice reinforced a broader principle:
movement selection must serve both clinical goals and system reliability.
A Clearer Identity Moving Forward
Week 11 was not about building more—it was about deciding what ReNUSHU stands for.
By committing to abstraction, symbolic reward, and safety-first design, the team clarified how rehabilitation, technology, and play should intersect in this project. The Balloon + Word Game is not just a new mini-game; it is a concrete expression of the design philosophy that now anchors ReNUSHU.
Therapeutic movements do not need to be represented literally to be meaningful.
They need to be respected, supported, and framed in a way that encourages people to return.
From rehab to play, and from play to progress.
