A step-by-step example:How the AgeTech Prism™ Works

A kit of small sensors for the home of an older adult who lives alone: a contact sensor on the front door, a motion sensor in the hallway, a pressure mat under the mattress, and a contact sensor on the refrigerator door. A hub learns the household's daily pattern and sends alerts when the pattern breaks. The kit has no cameras or microphones, and the resident wears nothing.

What enters the prism is the product's marketing promise, together with every public trace that lends the promise credibility or takes it away. Each is quoted below, with what it does to the promise.

“Peace of mind, with no cameras.”

The prism separates the beam into five facets: the vendor, the product, the people it serves, the fit of the experience to the aging adult, and the vendor's compliance and conduct. Twenty attributes are placed on one ladder, Level 1 to Level 5, which describes who directs the relationship between the product and the older adult. Five conformance attributes form the gate.

The organization behind the product, its grounding in the aging field, its evidence practice, and whether it can be held to account. Every placement below is an observation of the public materials, then the reading.

Aging-field grounding of the teamLevel 2

Public materials document a team page that names a founder from consumer electronics and an advisory board of two hardware engineers, with no gerontology, therapy, nursing, or social work role named. The placement reads Level 2.

Evidence: About page, the team

Older adults in the design processLevel 3

Public materials document a pilot in twelve households with feedback sessions held with adult children, and no sessions described with the residents themselves. The placement reads Level 3.

Evidence: Company blog, the twelve-household pilot

Accountability and continuityLevel 3

Public materials document a named company, a postal address, a support line with stated hours, and an end-of-service policy of ninety days' notice with a data export. The placement reads Level 3.

Evidence: Support and end of service

Standing: evidence practice and partnershipsLevel 2

Public materials document two testimonial quotes and a partnership with home-care agencies, with no published study, registry entry, or independent evaluation named. The placement reads Level 2.

Evidence: Care partners; App store review, from a daughter

The promise and the evidence offered for it, how the aging person is framed, what happens to data and AI, and what it costs. Every placement below is an observation of the public materials, then the reading.

Silence about AI on a digital product is read as Undisclosed. The public footprint holds no statement on the deciding fact, so no level can be read, and the attribute counts against the vendor's disclosure.

The promise and the evidence offered for itLevel 3

Public materials document the sensors, the daily summary, and the alert rules behind the promise of peace of mind with no cameras, with the early-warning claim resting on the Insights page alone. The placement reads Level 3.

Evidence: Home page, headline and first paragraph; What is in the box; Insights page

How aging is framedLevel 3

Public materials document the resident described as a loved one whose day has a rhythm and as the source of the signal, with the resident's own goals absent from every material. The placement reads Level 3.

Evidence: Home page, headline and first paragraph

Data collected and sharedLevel 2

Public materials document the data collected, door, motion, bed, and refrigerator events, shared with Circle members and retained for the life of the account, with consent given by the Circle Owner. The placement reads Level 2.

Evidence: Section 4, Who sees household activity data

AI use and its disclosure to the personUndisclosed

The public materials state nothing about whether a model decides the alerts and the early-warning flags, what it learns from, or what the resident is told. The attribute reads Undisclosed.

Price postureLevel 3

Public materials document a starter kit at a stated price and a monthly plan cancellable at any time, sold direct and through participating home-care agencies, with no reduced-cost route described. The placement reads Level 3.

Evidence: Plans

Who the product names as its beneficiary, the older adult's own way in, and the helper roles it depends on. Every placement below is an observation of the public materials, then the reading.

Beneficiary named and profiledLevel 3

Public materials document the beneficiary named as an older adult living alone, with intact locomotion and cognition assumed and nothing stated about vision or hearing. The placement reads Level 3.

Evidence: Home page, headline and first paragraph

The older adult's own way inLevel 1

Public materials document alerts sent to Circle members' phones, with setup, pausing, and consent belonging to the Circle Owner, and no account, view, say, or consent step described for the resident. The placement reads Level 1.

Caps the reading

Evidence: Setting up the Circle

Helper roles disclosedLevel 4

Public materials document the Circle Owner and Circle members as named roles with stated powers, including agency staff as members, with what each helper sees and decides documented in full. The placement reads Level 4.

Evidence: Setting up the Circle; Care partners

Each attribute is read with an inspection method from usability, accessibility, content design, or service design, applied to the manuals, screenshots, listings, and help pages, and with one rule from environmental gerontology: a demand is a barrier when it exceeds the beneficiary's capacity on the relevant domain, and a facilitator when the product lets the person tune it. 2 placements below rest on no documentation and read as provisional.

Setup and prerequisitesLevel 4

Public materials document four sensors placed in about twenty minutes by the Circle Owner, with the resident wearing nothing and installing nothing. The placement reads Level 4.

Evidence: What is in the box

Daily use and upkeepLevel 4

Public materials document nothing for the resident to charge, press, or remember. The placement reads Level 4.

Evidence: What is in the box

Failure and withdrawal behaviorLevel 4

Evidence: When the hub loses power or Wi-Fi

Perceptual and motor accessibilityLevel 4

Public materials document a resident who carries no interface and so meets no sensory or motor demand, and a Circle app that offers adjustable text size and labeled controls for screen readers. The placement reads Level 4.

Evidence: What is in the box; Circle app, accessibility features

Cognitive load and interaction complexityLevel 3

Public materials document one behavior for a resident with memory change: alerts flow to the Circle exactly as before, with no material addressing cognition directly. The placement reads Level 3.

Provisional

Language, literacy, and localizationLevel 3

Public materials document a Circle app offered in English and Spanish, with the printed setup card included in the box in English only. The placement reads Level 3.

Evidence: Language support

Onboarding, help, and supportLevel 3

Provisional

Care-organization workflow fitLevel 4

Public materials document agencies enrolling as Circle members, receiving alerts in their own dashboard, and handing off between shifts, with the workflow documented in full. The placement reads Level 4.

Evidence: Care partners

Five obligations set outside the product, by standards, regulators, and consumer law. Each is read as Supports, Partially supports, Does not support, or Not applicable. The row is printed beside the reading and stays out of the level. An unmet obligation can cap the level the product reaches.

Accessibility conformanceDoes not support

Public materials document no accessibility statement or conformance report published for the app or the hub.

Privacy, consent, and data rightsPartially supports

Public materials document a privacy policy naming the data collected, its sharing with Circle members, and a deletion route, with consent given by the Circle Owner on the household's behalf.

Person in the loop and AI governance statusDoes not support

Public materials document alerts raised automatically, with no material describing a person reviewing them or a way for the resident to pause or override them.

Health or device authorization where the claim requires itNot applicable

Public materials document a stated wellness position with no diagnostic or medical claim, so no health or device authorization is required.

Terms, payment fairness, and service commitmentsPartially supports

Public materials document monthly cancellation and a stated end-of-service notice, alongside an arbitration clause and a clause allowing the terms to change with continued use as acceptance.

The five facets converge into one reading.
