Wisdom is a privacy-preserving smart home care system designed to support older adults who want to remain safely in their own homes, while providing families and home care providers greater confidence and insight. Using radar and optical sensing with no reliance on a wearable device, Wisdom detects falls, inactivity, and changes in daily routines. Alerts are shared with a trusted circle that can include family members and professional caregivers, enabling timely check-ins or escalation when needed. For home care agencies, Wisdom complements in-person care by providing passive, 24/7 visibility between visits, helping reduce risk, support aging in place, and strengthen communication with families.
