Portable terminal accessory device for holographic projection and user interface
A holographic display system for a portable electronic device. The display system includes a case configured to receive the portable electronic device and a projector coupled to the case by a first hinge element. The projector includes a projector screen for generating images. A reflective element is coupled to the projector by a second hinge element. The reflective element is oriented to reflect light from the images in order to create holographic images perceptible to a user of the portable electronic device. The case may include a connector for receiving, from the portable electronic device, a video signal defining the images. The holographic display system may further include a substantially transparent touch screen attached to the first hinge element.
1. A holographic display assembly for a portable electronic device, the display assembly comprising:
a projector including a projector screen for generating images;
a reflective element;
a touch screen and
a collapsible hinge system configured to facilitate opening of the holographic display assembly from a collapsed state to an opened state, the collapsible hinge system including a base hinge coupled to the projector wherein the projector screen is substantially perpendicular to the touch screen when the bolographic display assembly is in the opened state and wherein the touch screen is substantially parallel to the projector screen when the holographic display assembly is in the collapsed state;
wherein the reflective element is oriented to reflect light from the images in order to create holographic images perceptible to a user of the portable electronic device when the holographic display assembly is in the opened state.
2. The holographic display assembly of claim 1 wherein the projector screen is movable between an extended state substantially perpendicular to a display screen of the portable electronic device and a collapsed state substantially parallel to a rear surface of the portable electronic device.
3. The holographic display assembly of claim 1 wherein the reflective clement is movable between an extended state at an acute angle to the projector screen and a collapsed state substantially parallel to the projector screen.
4. The holographic display assembly of claim 1 wherein the reflective element includes a holographic foil backed by a protective casing.
