Description
Apparatus and Method for a Bioptic Real Time Video System
Field of the Invention
The invention relates generally to the field of wearable electronic displays and more specifically to the field of vision care.
Background of the Invention
There are numerous applications for lightweight head-worn near-lo-eye displays.
These are commonly called Head Mounted Displays (HMD). HMDs display to the eye an electronically rendered image such that the wearer perceives that they are watching a sizeable electronic display at some distance in front of them. The applications that use such HMDs are numerous, including but not limited to virtual reality, electronic gaming, simulation environments such as for military simulations or flight simulators, medical applications such as for the
enhancement of sight, and consumer applications such as the ability to view videos in a mobile setting.
One of the fundamental challenges of HMDs is the tradeoff between the display's Field of View (FOV), being the size of the virtual display as perceived by the wearer, and pixel size. FOV is normally defined as the number of angular degrees subtended within the viewer's overall field of vision, horizontally, vertically, or on the diagonal. Horizontal FOV dimensions in the range of 20-30 degrees are typical, with larger dimensions being possible at significant expense. Pixel size is similarly expressed as the number of angular arc minutes (1/60* of a degree) subtended by a single, typically square pixel element, As one might
expect, to achieve a larger FOV with a given pixel resolution (number of pixels), results in a larger pixel size, and consequent loss of image detail.
Peripheral vision is that portion of the human field of vision outside the center, say, 10-15 degrees FOV. Peripheral vision is extremely important in some HMD applications, especially those in which the wearer must maintain a connection with their natural environment to contextualize their situation, and enable way finding, orientation, and mobility. To provide significant peripheral vision via the electronic display requires an extremely large (and expensive) HMD.
Alternately HMDs which provide a significant natural peripheral vision external to the HMD housing, provide a very limited virtual electronic FOV.
Many HMD applications can benefit from the incorporation of a live camera into the HMD, such that the wearer can not only view electronic data from a source, such as a video file, but also live video images of the world in front of them. Image processing can be used to enhance the live camera image before it is presented to the eye, providing magnification, enhancement of brightness, or improved contrast for example.
In HMD systems that are to be used for multiple activities, different camera angles may be required for different tasks. For example, to observe an object a distance, the camera angle should be nearly horizontal relative to the horizon when (he wearer's neck is straight and their gaze angled at the horizon. On the other hand, to view hand-held objects at a close distance requires a camera that is angled downward, in order to avoid a highly exaggerated downward neck posture. In this manner, the angle of the camera mimics the angular movement of one's eyes in a non-HMD world.
Finally, the angle of the display relative to the eyes is also dependent on the specific tasks of the wearer, in certain situations the wearer would like to look into the electronic display only temporarily, and by looking up at an angle higher than their habitual gaze. In other situations, the wearer would prefer a more immersi ve usage model, where the electronic display is directly in front of their normal line of gaze.
What is needed then is a general HMD device that is capable of providing significant unobstructed peripheral vision outside of the electronic display FOV, while simultaneously providing a high resolution video image. Further, the ability to adjust the angle of the display and the camera according to the wearer's specific activity would provide significant comfort and increased usability.
Summary of the Invention
The ability to quickly alternate as required by the specific task, between viewing an image presented in the electronic display and viewing the world without the electronic display, enables many possible usage models for an HMD.
Furthermore, in an IIMD with an integrated camera, the ability to adjust the vertical camera angle for different tasks, viewing objects distant and close for example, significantly increases the usability of such a device. Finally, an HMD whereby the user is able to select the vertical position of the electronic display, in order to tradeoff a comfortable immersive video experience versus maintaining a broad natural field of view enables the HMD to be used in a variety of user applications and postures.
The invention, in one aspect, relates to a method of orienting an electronic near- to-eye display such that the wearer views it slightly above their habitual line of sight for a given task. In this manner the wearer, through slight neck and eye
angle adjustments can, with minimal effort, alternate between the electronic display and their natural vision.
In one embodiment, the electronic display is mounted slightly above the wearer's habitual line of sight, so that by angling the neck slightly forward and directing their gaze slightly upward, they can look into the display. Alternately by angling the neck slightly back and directing their gaze slightly down, they can view below the electronic display using their natural vision,
In another embodiment, the apparatus incorporates the wearer's prescription ophthalmic lenses, so that whether they gaze up into the electronic HMD or down using their natural vision, they are able to do so through their prescription lenses. This embodiment of the invention alleviates the need to switch between the HMD device and the wearer's habitual spectacles.
In another embodiment the apparatus incorporates a video camera, which provides the video information to the electronic display, the angle of the camera being adjustable as required by the specific task.
in any of the above embodiments the source of the video may come from a device other than the camera, in any standard electronic video format such as MPEG for example.
In another embodiment the apparatus may deploy motion sensing components in order to facilitate image stabilization for the electronic video image that is captured by the camera.
In another embodiment the motion sensing components could be used to determine the angular orientation of the apparatus, so that the vertical camera angle can be automatically adjusted based on head position.

Description of the Preferred Embodiment
In brief overview and referring to Fig. 1, the system in one embodiment includes prescription lenses 6 mounted to an eyeglasses frame 1. The Head Mounted Display portion of the system comprises a housing 2, which can move relative to the eyeglasses frame 1, about a pivot point 3. The HMD housing 2 incorporates HMD optics 5, a camera 9, and HMD electronics 8 (collectively, the "HMD").
In the orientation depicted in Fig 1., the wearer's head/neck posture is angled slightly back 4, and he is viewing the world 7 through the prescription lens 6, without the use of the HMD optics 5 or camera 9.
In Fig. 2, the head/neck angle 4 is slightly forward, allowing the user to view the HMD optics 5 through the same prescription lens 6 by directing their gaze at a slight upward angle 7. In this mode, video information viewed through the HMD optics 5 can be provided from the video camera 9, oriented at an outward angle 10 such that objects at a distance can be viewed in the video image. As discussed, the video could also come from other sources.
In Fig. 3 the head/neck angle 4 is unchanged from Fig. 2, but the camera has been angled downward on a pivot point 1 1 so that the camera angle 10 is now aimed at a nearby object close at hand, perhaps in the wearer's hands.
In Fig. 4 the slightly forward head/neck angle 4 remains unchanged, but the HMD angle has been significantly lowered by pivoting the HMD housing 2 relative to the eyeglasses frame 1, around a pivot point 3. In this orientation the wearer is able to adopt a more comfortable viewing angle 7 for near-in tasks. Furthermore, the camera angle 10 can be directed further downward because the camera pivot point 1 1 moves with the HMD housing 2.
In Fig. 5, a method is shown whereby a linear motor 12 can be used to adjust the vertical angle 10 of the camera 9, The camera rotated around a pivot point 1 1 that is affixed to the HMD housing 2. With the adjustment of the camera angle automated thus, it is possible to use motion and position sensors embodied in the HMD electronics 8, to provide positional data that can be used to control the linear motor 12.
Alternately, the angle 10 of the camera 9 can be adjusted manually by the user.
Fig. 7 shows how the same motion and position sensors embodied in the HMD electronics 8 can be used to enable an image stabilization function. Figs. 7a, 7b, and 7c show three consecutive frames of video as captured by the camera 9. Because of the normal movement of the wearer's head, successive frames of video halve a translational (up/down, left/right) and rotational (angular) position relative to the previous frame. The frame depicted in Fig. 7b for example has shifted to the right/down and rotated slightly counter-clockwise relative to the previous frame 7a. The translational vector Λι and rotational angle θ[ can be determined from the motion and position sensors embodied in the HMD electronics 8. By applying the opposite of the translational vector and the reverse rotational angle to the pixels in the video frame 7b, the differences between the two frames 7a and 7b can be removed. Figure 7c carries the example farther, showing a frame of video that is now shifted left/down and clockwise relative to the previous frame 7b. A new vector Δ2 and rotational angle Θ2 can be applied, and so forth so that over time, small frame-to-frame variations caused by the wearer's head movement are removed from the displayed video. To distinguish between minor head movements, for which image stabilization should be applied, and gross head movements, which indicate the wearer's scene of interest has changed, requires that the image stabilization function only be applied to small translational and rotational vectors.
In 8a and Sb, the angle of the camera 9 is adjusted not by physically rotating the camera as previously discussed. Rather, an area of pixels, or a window 13, 14 can be defined on the image sensor so that the wearer perceives that the camera angle is physically altered. This technique requires a camera system wherein the usable image sensor area is larger than the video that is to be displayed to the
wearer. Motion and position sensors embodied in the HMD electronics 8 can be used to determine the wearer's head/neck angle 4 and, based on this information, define a capture window 13, 14 that gives the wearer the perception of a high or low camera angle 10.
While the present invention has been described in terms of certain exemplary preferred embodiments, it will be readily understood and appreciated by one of ordinary skill in the art that it is not so limited, and that many additions, deletions and modifications to the preferred embodiments may be made within the scope of the invention as hereinafter claimed.
