One variation of a system for imposing a dynamic sentiment vector to an electronic message includes: a processor; an electronic computing device communicatively coupled to the processor and associated with a particular user; and a sentiment vector generator comprising: a parsing module; a dynamic sentiment value spectrum associated with the particular user; and a program executable by the processor and configured to: receive a text input comprising message content from the electronic computing device; parse, at the parsing module, the message content comprised in the text input for emotionally charged language; based on the emotionally charged language, generate a sentiment value from the dynamic sentiment value spectrum for the text input and, based on the sentiment value, impose a sentiment vector, corresponding to the assigned sentiment value, to the text input, the imposed sentiment vector rendering a sensory effect on the message content designed to convey a corresponding sentiment.
