Abstract
A head-mounted display apparatus includes a head-mounted display, the head-mounted display including a plurality of independently controllable switchable viewing areas that can each be independently switched between a transparent state and an information state. The transparent state enables a user of the head-mounted display to see the scene outside the head-mounted display through the independently controllable switchable viewing areas. The information state is opaque and displays information in the independently controllable switchable viewing areas visible to a user of the head-mounted display. Circuitry produces a control signal for controlling the states of the independently controllable switchable viewing areas and a controller responsive to the control signal independently switches each of the independently controllable viewing areas between the transparent state and the information state.
