IT applications that support aging in place: seven categories of need Mike Rosen Outgoing Director Rehabilitation Engineering Labs National Rehabilitation Hospital Disclaimer: This talk is about meeting the needs of elders by using technology. Therefore it will focus on technology. It is, however, the position of the speaker, his colleagues and family that IT must be applied in the context of an integrated consumer- centered system of health care and support for independent living. Slide 2 Seven killer apps that support life and living Emergency detection and response-cuing Emergency detection and response-cuing Activity tracking for status monitoring Activity tracking for status monitoring Task sampling for status monitoring Task sampling for status monitoring Health maintenance Health maintenance Cognitive support in ADLs Cognitive support in ADLs Enhanced communication with the outside Enhanced communication with the outside Access to information and stimulation Access to information and stimulation Note: first three are about service delivery; last three are assistive; fourth one can be either depending on ones model of health care. Slide 3 First application Emergency detection and response-cuing Emergency detection and response-cuing Activity tracking for status monitoring Activity tracking for status monitoring Task sampling for status monitoring Task sampling for status monitoring Health maintenance Health maintenance Cognitive support in ADLs Cognitive support in ADLs Enhanced communication with the outside Enhanced communication with the outside Access to information and stimulation Access to information and stimulation Talking Lights Slide 4 For example: Critical medical events (e.g. stroke, coronary, diabetic coma) Critical medical events (e.g. stroke, coronary, diabetic coma) incapacitated incapacitated some capacities intact some capacities intact Falls Falls conscious but immobile conscious but immobile at home at home away away unconscious unconscious at home at home away away Wandering (secondary to dementia) Wandering (secondary to dementia) aware aware unaware unaware Note 1: Engineering challenges vary dramatically across these examples; e.g. sensor integration and knowledge-based processing for automated fall detection. Note 2: Automated solutions must take into account the costs of false positives and false negatives.

Targeted processing of wearable sensor signals to detect/measure particular symptoms, e.g. tremor, spasticity, o.c.d. Note 1: This kind of instrumented monitoring may be felt as less intrusive than video. Note 2: Wireless solutions are nearly essential. Note 3: Either modular retro- fittable senor products (like X10) or smart home integrated systems*. *MIT, GA Tech, Intel, GE, Rochester Slide 7 Third application Emergency detection and response-cuing Emergency detection and response-cuing Activity tracking for status monitoring Activity tracking for status monitoring Task sampling for status monitoring Task sampling for status monitoring Health maintenance Health maintenance Cognitive support in ADLs Cognitive support in ADLs Enhanced communication with the outside Enhanced communication with the outside Access to information and stimulation Access to information and stimulation Slide 8 the premise Unobtrusive monitoring of selected ADLs in the home is technically feasible and practical. Unobtrusive monitoring of selected ADLs in the home is technically feasible and practical. Performance of ADLs is the most direct and ecologically valid indicator of functional status (and rehab outcome). Performance of ADLs is the most direct and ecologically valid indicator of functional status (and rehab outcome). ADL event time records can be processed to return meaningful estimates of global functional status for display to OTs and other remote service providers ADL event time records can be processed to return meaningful estimates of global functional status for display to OTs and other remote service providers without video without video Slide 9 NRH project design First: develop and demonstrate a prototype sensor package and data- acquisition hardware and software for installation in a kitchen: done First: develop and demonstrate a prototype sensor package and data- acquisition hardware and software for installation in a kitchen: done Wired Independence Square at NRH Slide 10 unobtrusive sensors: so far just switches Is the faucet running?

Elders are themselves a huge and growing market; but many of these IT apps or their core technologies suit virtually the entire population.
