Head mounted video and touch detection for healthcare facility hygiene
A system and method tracks touches in a healthcare environment in order to analyze paths of transmission and contamination for the purpose of eliminating and containing transmission of colonizing, drug-resistant pathogens. Touches are identified and tracked with the use of recording devices. Each touch is logged and a touch graph is generated to identify transmission paths.
1. A method for touch detection and analysis, comprising
using a processor device, performing steps of:
receiving from a first device, data comprising an indication that a touch has occurred within a setting comprising a plurality of identified persons, a plurality of identified objects, and a plurality of identified surfaces, the data received from the first device including touch identification from a touch identification system comprising at least one of: a head-mounted display camera and an intrabody near-field communication network;
automatically analyzing the data to identify the touch;
logging the touch occurrence in a touch store;
generating a transmission graph from logged touches to identify deleterious entity transmission paths, said transmission graph comprising:
a node representing each person, each object, and each surface involved in the touch occurrence; and
edges between the nodes representing the touch occurrence; and
analyzing the touch graph to identify candidate transmission paths; and
using the touch identification system to increase confidence levels in the identification of the candidate transmission paths from the touch graph.
