METHOD AND SYSTEM FOR ASSESSMENT OF COGNITIVE FUNCTION BASED ON MOBILE DEVICE USAGE

摘要

A system and method that enables a person to unobtrusively assess their cognitive function from mobile device usage. The method records on the mobile device the occurrence and timing of user events comprising the opening and closing of applications resident on the device, the characters inputted, touch-screen gestures made, and voice inputs used on those applications, performs the step of learning a function mapping from the mobile device recordings to measurements of cognitive function that uses a loss function to determine relevant features in the recording, identifies a set of optimal weights that produce a minimum of the loss function, creates a function mapping using the optimal weights, and performs the step of applying the learned function mapping to a new recording on the mobile device to compute new cognitive function values.

1. A computer implemented method to quantify the effect of social interaction, mobility, physiology, cognitive stimulation, and diet on a person's brain health, said method comprising the steps of:
a. recording at a mobile computing device an in vivo input associated with a measurement of one of social interaction, mobility, physiology, cognitive stimulation, and diet; b. recording interaction inputs associated with one or more interactions of the person with said mobile computing device; c. executing a learning function mapping to compute a brain health measure based on said person's interaction inputs, wherein said brain health measure is one of a neuropsychological benchmark test; d. performing the learning function mapping from said recording associated with the in vivo input to said computed brain health measure; and e. outputting an attribution to said brain health measure that is explained by said in vivo input.
