Independence Index: 10 Daily Activities Where Smart Home Supports Elderly Living Alone
The number one family concern for elderly living alone is: what if something happens and nobody knows? This index maps 10 daily activities with specific analysis of how Smart Home supports each and reduces risk.
Activity 1: Waking Up (06:00–07:00)
Risk: Falling while getting out of bed — causes 30% of in-home falls. Smart Home support: mmWave detects abnormally long bed occupancy (>9 hours) and alerts family; Circadian Light enables natural wake; night lights auto-activate. Result: Eliminates need for family to call every morning 7 days per week.
Activity 2: Bathroom Visit (06:30–07:00)
Risk: Bathroom falls — 80% of severe falls occur in bathrooms. Smart Home support: mmWave in bathroom detects falls or abnormal stillness (>15 minutes) → immediate LINE Notify alert. Result: Reduces response time from hours or days (discovered at next visit) to under 5 minutes.
Activity 3: Morning Medication (08:00)
Risk: Forgotten or double-dosed medication — occurs in 28% of elderly living alone. Smart Home support: Smart Pill Dispenser with alert and compartment lock, contact sensor on medication drawer, LINE confirmation message. Result: 91% reduction in missed doses in 6-month studies.
Activity 4: Cooking Breakfast (08:00–09:00)
Risk: Fire or gas leak — elderly are 3× more likely to leave a burner on. Smart Home support: Smoke+CO sensor with immediate alert; Smart Plug on electric hob auto-cuts power when no kitchen movement detected for >30 minutes. Result: 65% reduction in cooking-related fire events.
Activities 5–7: Daytime Activities (09:00–17:00)
Resting, hobbies, lunch. PIR monitors normal activity patterns; mmWave flags abnormally long daytime sleep (>3 hours) indicating potential health anomaly. Daily Activity Score report sent to family via LINE.
Activity 8: Afternoon and Evening Medication (13:00, 18:00)
Smart Pill Dispenser repeat alerts → confirmation → evening summary report.
Activity 9: Shower/Bath (18:00–19:00)
mmWave plus waterproof Panic Button in bathroom. Emergency LINE alert if button pressed or fall detected.
Activity 10: Going to Bed (21:00–22:00)
mmWave confirms bed occupancy; door sensor logs bedroom entry → summary report "all normal" sent to family before midnight.
ROI: Caregiver Hour Reduction
