the published aws case study
amazon web services published this case study at aws.amazon.com/solutions/case-studies/electronic-caregiver/ in january 2019. the archived version is preserved below and verifiable via the internet archive.
what we built
addison care™ is an interactive, voice-controlled virtual caregiving solution featuring a 3d augmented-reality character. patients interact with addison via tablets installed throughout their homes, connected to wireless visual sensors, local ai processors, bluetooth biometric wearables, and emergency monitoring devices.
the system detects gait anomalies, provides medication and treatment reminders through specialized modules for diabetes, heart disease, and copd, and learns about the patient through continuous observation. serving seniors who need health monitoring but cannot afford in-home human caregivers at $20/hour.
technology stack
Amazon Sumerian™ rendered 3d scenes. Amazon Lex™ handled conversational ai. Amazon Polly™ provided text-to-speech. AWS Lambda™ ran serverless logic. Amazon DynamoDB™ stored health markers. AWS Amplify™ hosted scenes. AWS IoT Greengrass™ ran facial-recognition locally on tablets, even offline.
development breakthrough
three years with a traditional game engine produced eight-month cycles with teams of 10-12. within two hours of accessing Amazon Sumerian, developers were building scenes. three months later, addison was complete — two-person teams averaging 70 iterations per developer per day.
