1. A wearable heads-up display (WHUD) comprising:

  • a support structure that in use is worn on a head of a user;

    a transparent element that is physically coupled to the support structure, wherein the transparent element is positioned within a field of view of the user when the support structure is worn on the head of the user;

    at least one light source physically coupled to the support structure and positioned near or beyond a field of view of the user when the support structure is worn on the head of the user;

    at least one light-redirection element physically coupled to the support structure and positioned to receive light signals provided by the light source and redirect the light signals towards the transparent element; and

    a number n of dynamic reflectors positioned on the transparent element in the field of view of the user when the support structure is worn on the head of the user, where n is any integer greater than 1, wherein the n dynamic reflectors receive light signals redirected by the at least one light-redirection element, and wherein the n dynamic reflectors are each controllably variable by rotation about at least two orthogonal axes to reflect light signals towards select regions of at least one eye of the user.
