Why a 4-Dimension Wellness Framework Is Needed
Smart Home projects claiming to support elderly Wellness rarely provide clear metrics, making purchase decisions difficult and leaving residents unable to know whether installed systems are actually working. The 4-Dimension framework presented here allows families to systematically evaluate Smart Home Wellness quality and make fully informed investment decisions.
Dimension 1: Physical Wellness — Measurable Health Outcomes
Key KPIs:
- Indoor PM2.5 ≤ 12 µg/m³ at all times (WHO Indoor Standard target)
- Indoor temperature stable at 24–26°C during 20:00–06:00 for sleep quality
- Days per month with Blood Pressure in normal range (measured by Smart Watch)
- Sleep Quality score (Deep Sleep ≥ 20% of total sleep time)
Measuring devices: Air Quality Sensor, Smart Thermostat, Withings ScanWatch, Smart Bed with Sleep Tracking.
Dimension 2: Mental Wellness — Measurable Psychological Outcomes
Key KPIs:
- Number of anxiety-driven calls to family members per month (decrease = improvement)
- Monthly Self-Report Anxiety score (GDS-5 Anxiety Screen)
- Social activity hours per week (via Smart TV, Video Call)
- Daily Routine consistency (measured by Motion Sensor patterns)
Supporting devices: Smart Speaker (music therapy), Smart TV (Video Call), Voice Assistant (loneliness reduction).
Dimension 3: Safety Outcomes — Measurable Protection Results
Key KPIs:
- Number of fall incidents (target = 0 per year)
- Response time when anomaly is detected (target ≤ 3 minutes)
- Number of alert-and-response successes by family
- System Uptime ≥ 99% per month (measured from dashboard)
Measuring devices: mmWave Fall Sensor, AI Camera, Panic Button, Gas Sensor.
Dimension 4: Independence Score — Measurable Autonomy
Key KPIs:
- Number of activities completed independently per week without assistance
- IADLs (Instrumental Activities of Daily Living) Score per quarter
- Hours without caregiver present in which elderly still feels safe (Self-Assessment)
- Daily autonomous decisions made by the elderly (Autonomy Index)
Supporting devices: Voice Control, Smart Lock (go out independently), Medication Dispenser.
Practical 4-Dimension Tracking
High-quality projects provide Monthly Wellness Reports aggregating Smart Device data into a readable dashboard. Bangkok projects achieving full 4-dimension tracking:
SilverAge Residence Asok: Wellness Nurses produce full 4-dimension Monthly Reports sent to physicians and family.
WellNest Ramindra: App Dashboard displays weekly Sleep Score, PM2.5 History, Fall Events, and Daily Activity.
Harmony ElderCare Smart Villa Bangna: Quarterly IADLs Assessment by geriatric nurses, with system adjustments based on results.
Baseline Measurement Before Installation
Before installing Smart Home, it is recommended to measure baseline values across all 4 dimensions to enable comparison at 3 and 6 months post-installation. Real-world experience shows elderly with complete 4-dimension systems report 35–50% higher quality of life compared to pre-installation.
