  • Publication number: 20210134043
    Abstract: An intuitive interface may allow users of a computing device (e.g., children, etc.) to create imaginary three dimensional (3D) objects of any shape using body gestures performed by the users as a primary or only input. A user may make motions while in front of an imaging device that senses movement of the user. The interface may allow first-person and/or third person interaction during creation of objects, which may map a body of a user to a body of an object presented by a display. In an example process, the user may start by scanning an arbitrary body gesture into an initial shape of an object. Next, the user may perform various gestures using his body, which may result in various edits to the object. After the object is completed, the object may be animated, possibly based on movements of the user.

  • Publication number: 20200348590
    Abstract: The present invention discloses a digital photolithography method for a fiber optic device (FOD) based on a DMD combination. In this method, reflected light modulated by two DMDs is simultaneously projected onto a same position on an optical fiber end surface through one reduction projection lens. The two DMDs form a primary and secondary digital mask for joint control of an exposure dose distribution formed when patterns are shrunk and projected onto the optical fiber end surface. After the optical fiber end surface coated with photoresist is subject to this dose of exposure, developing, fixing, and etching are conducted, to form a micro-optic device on the optical fiber end surface. In the present invention, distribution of the exposure dose jointly modulated by a digital mask combination formed by the primary and secondary DMD exceeds an order of modulation of an exposure dose by a single DMD.
