Familiar moments, everyday support
01 / Background
A question from a nursing-home visit
During a community activity at a nursing home, I noticed that some older adults responded slowly. Caregivers explained that some were living with Alzheimer’s disease. The visit prompted a question: how could everyday interactions offer support beyond routine care?
From care to everyday connection
I began exploring mixed reality through daily guidance, familiar family memories and playful cognitive activities — with caregivers and family members included in the experience.

UI & MR sketches
Companion app · Patient overview, memory upload and tracking.
MR scenes · Recognition, navigation, exercises and shared family memories.
Comfort within reach
Original field-of-view study and spatial UI concept.
Initial prototype targets, adjusted through distance and brightness controls.
50–70 cm
Start at 60 cm; frequent controls at 40–60 cm.
100–300 cd/m²
Start at 150 cd/m²; allow adjustment.
100–120° / 60°
Horizontal / vertical view; keep controls easy to reach.
I explored viewing distance, brightness and field of view to keep the interface within a natural sightline. Frequently used controls sit closer, with reachable angles and limited tilt.
Simple hand interactions
Poke
Point forward to press a button.
Pinch
Bring thumb and index finger together to grab.
Return home
Gather all fingers to return to the home page.
Visual identity
The final mark depicts an older adult leaning on a cane, with a warm yellow background.
Puzzle prototypes
Family portrait puzzle
Rebuild family photos to explore memory recall.
Spatial perception game
Move 3D blocks to explore spatial perception.
Social Stacks
Build together through shared block play.
Collaborative Cubes
Use shared roles to assemble structures together.
Prototype logic · Unity / C#
Matching pieces snap into position; the grab interaction is then released.
Vertical input moves blocks, while collision events gate movement.
