    This Sony patent application refines ways of viewing display content from a smartphone. Reminiscent of one of the earlier use-cases for PicoP, the proposed device includes a swivel-out holographic light guide similar to the light guide Sony developed for Smarteyeglass. When the optic is swiveled out, a pair of image sensors are revealed to allow the user to capture real-world 3d images--while at the same time using the eyepiece to interact with graphical elements, etc--controlled by gestures, etc.

    Kind of a hand-held equivalent of Google Glass in a discreet form factor. Easily as versatile.

    The patent describes an audio and smartphone device with a conventional OLED display. A second display is described as a type, “transmissive” or “transmission”. “light beam propagation” is a term used. But no mention of specifics.

    U.S. Patent Application 20150207908

    July 23, 2015



    There is provided a mobile terminal including a casing that includes an audio output unit that outputs audio, and a transmissive display unit provided rotatable about the casing. The transmissive display unit is disposable in a plane intersecting a principal face of the casing while the audio output unit is outputting audio.

    Depending on how handy this is, the latent demand is equivalent to 1.74 billion smartphone users worldwide.

    There are already those who would consider purchasing more than one.

    Interesting point, DGL. Sony's smartphone *companion* could set a precedent for a new kind of essential. Sony should get a head start across many brands & users. They may even sell more standalone projectors than smartphones, right?

    doubledown, who is "they"? Magic Leap was founded in October 2014.

    Scanning fiber IP belongs to University of Washington. Magic Leap patents include an embodiment for LBS scanning displays--in case the scanning fiber idea is unworkable. IMO, the scanning fiber method is relatively untested.

    IOW, PicoP can deliver a more memorable big screen experience..

  • green_lanterns_11 by green_lanterns_11 Jul 28, 2015 7:36 PM Flag

    We alternate watching movies between a 90" projection screen and my wife's MacBook. The following day, I easily recall the big screen feature we watched--often forget the MacBook movie--fwiw.

    Integrated photonics module for optical projection


    Optical apparatus includes a semiconductor substrate and an edge-emitting radiation source, mounted on a surface of the substrate so as to emit optical radiation along an axis that is parallel to the surface. A reflector is fixed to the substrate in a location on the axis and is configured to reflect the optical radiation in a direction that is angled away from the surface. One or more optical elements are mounted on the substrate so as to receive and transmit the optical radiation reflected by the reflector.

    Applicant: PRIMESENSE LTD.

    Assignee: APPLE INC. (Cupertino, CA)

    “In one embodiment, the reflector includes a scanning mirror, which is configured to scan the reflected optical radiation over a predetermined angular range. The scanning mirror may include a micro-electrical mechanical system (MEMS) driver, which is mounted on the substrate at a diagonal relative to the surface on which the radiation source is mounted.”

    “IPM With Scanning Mirror
    FIG. 12 is a schematic sectional view of an IPM 200, in accordance with yet another embodiment of the present invention. Some elements of this embodiment are similar to those of IPM 80 (shown in FIG. 4) and are therefore marked with the same numbers. In IPM 200, however, the stationary mirror of the preceding embodiments is replaced by a scanning mirror 202.”

    “IPM 200 can be used to create patterned illumination without the use of a patterned element (which may thus be eliminated from the IPM) by pulsing laser diode 84 on and off in synchronization with the scan of mirror 202. This sort of patterned illumination can be used in pattern-based depth mapping schemes... Alternatively, modules based on the principles of IPM 200 may be used in a variety of other scanned-beam applications that can benefit for a very small, low-cost scanner.”

    Probably due to new touch feature..

    or, maybe something else (long shot)?

    From, The Week:

    iPhone 7 to get bulkier, leaked design suggests

    "A schematic drawing purporting to show the next iPhone – likely to be called either the iPhone 6S or iPhone 7 – suggests that the new handset will be thicker than the one it replaces, but will include few significant structural changes.

    According to the diagram, published by Engadget Japan, Apple's new phone will be 7.1mm thick, an increase from the iPhone 6's 6.9mm frame."

    MP-CL1 With Sensor(s)?

    If the stand were used with no keystone correction, the projected image would be a trapezoid. Sony would not go for this, imo. So, in lieu of real-time distortion correction, maybe when the stand is plugged into the slot, it causes an image correction optic to switch into place--for viewing at that preset angle. When the stand is removed, the correction optic retracts..?

    Yes, a slot for a stand. But why would Sony not debut a higher-end projector with 3D sensors--to generate maximum wow? If anyone can do it well, that would be Sony..

    From Sony Corporate News Release (7/20/2014)

    “...This module also delivers beautiful, crisp projection with a wide color gamut and higher contrast compared to conventional panel systems. In addition, it is equipped with an independently-developed distortion correction circuit which corrects screen shapes such as rectangles that can be distorted into trapeziums when projected from certain angles to their original shape...”

    I wondered why the stand was positioned to the side. My first thought was it covered a second projection opening.

    Sony said they would add distortion correction circuitry. If so, there needs to be forward facing 3D sensors, imo.

    I also wondered if the stand served another function--such as a reflector for tabletop display.

  • green_lanterns_11 by green_lanterns_11 Jul 25, 2015 11:42 AM Flag

    Several shots of MP-CL1 engineering sample. In image 1, see what appears to be a narrow slot opposite projection opening. Could this be for depth sensors?

    In their original PicoP press release, Sony mentions the addition of their own distortion correction circuitry.

    In the Wired photo, the projector is shown operating at an angle to the projection surface, I figure a forward facing sensor should be apparent.

    If MP-CL1 does have this capability, it should be popular indeed.


  • green_lanterns_11 by green_lanterns_11 Jul 24, 2015 6:21 PM Flag

    I admire the no-frills industrial design. A built-to-last look--like a good tool or instrument. The black (metal?) body resembles some of Sony's newer cameras that have returned to a more retro, form-follows-function appearance. Very cool, imo.

    I doubt that is the real KG.. The language seems off. Use of "then" instead of "than". Sounds more like one of those other tricksters. Karl knows Sony is working on a PicoP product--has studied Celluon's Sony PicoP module, etc.

    To describe Lenovo's "Image Correction" (and related patents), picture walking down a hall carrying a pico projector, pointing it along the wall. Like magic--doors, paintings, drapery, brickwork, etc, are painted over by a near-perfect image that is steady and flattened to your perspective. You’re walking, reading, working, or watching a video--all the while viewing the content head-on--from any angle..

    This is something of a companion to Lenovo’s “Image Correction” patent application. It outlines methods for detection of a user’s position (body & eyes) in order to minimize a display viewing angle. Other uses such as arranging graphical objects are described. The sensor hardware technology is left open. The method applies to nearly all display types.

    U.S. Patent Application 20150185832

    July 2, 2015



    For display alignment based on eye tracking, a method is disclosed that includes displaying, by use of a processor, a graphical object on a display screen, detecting an aspect of a user relative to the display screen, and moving the graphical object to reduce a viewing angle between the graphical object and the aspect of a user.

    Applicant: LENOVO (Singapore) PTE, LTD.

    3 of 20 Claims:

    “1. An apparatus comprising: a display screen; a processor in communication with the display screen; a display module that presents a graphical object on the display screen; a user module that determines an aspect of a user relative to the display screen; and an alignment module that moves the graphical object to reduce a viewing angle between the graphical object and the aspect of a user.”

    “2. The apparatus of claim 1 wherein the aspect of a user comprises a location of a user and the alignment module moves the graphical object to reduce a viewing angle between the graphical object and the user.”

    “3. The apparatus of claim 1 wherein the aspect of a user comprises a user's eyes and wherein the user module selects the graphical object from a plurality of graphical objects based on the graphical object being disposed at a location where the user's eyes are directed.”

    Laser light emission does not grows little in size at a distance from the laser source because it is ordered, collimated, or coherent. The tight beam packs the same light power wherever it travels. It is that single beam that is potentially damaging--especially at close range. Non-collimated light is dispersive at the photonic level.

    I've seen bits and pieces but nothing quite as comprehensive. It points to what's possible for mobile projection. Meaningful features that can take projection into entirely new uses.
