Event and movement monitoring using chromatic methodologies
Shaoqiu Xu, G.R. Jones · Measurement Science and Technology · 2006
An approach is presented for remotely monitoring person-based events at a series of locations in a domiciliary environment in order to extract information about movement between locations and to quantify the extent of any persistent events at a particular location. Each individual event is detected via a change in the optical chromaticity of a location and not the person. Movement between locations is determined using space and time-based chromaticity to analyse the dynamics of the sequence of events. An example of the deployment of the approach is presented.
