Abstract: This technology provides systems and methods for tracking facial movements and reconstructing facial expressions by learning skin deformation patterns and facial features. Frontal view images of a user making a variety of facial expressions are acquired to create a data training set for use in a machine-learning process. Head-mounted or neck-mounted wearable devices are equipped with one or more camera(s) or acoustic device(s) in communication with a data processing system. The cameras capture images of contours of the users face from either the cheekbone or the chin profile of the user. The acoustic devices transmit and receive signals to calculate a representation of the skin deformation. A data processing system uses the images, the profile of the contours, or skin deformation to track facial movement or to reconstruct facial expressions of the user based on the data training set.

Abstract: Systems and methods are provided for incremental 3D printing, wherein wireframes are generated and printed (scheduled for print) during the design process. In another aspect, systems and methods are provided for printing arbitrary meshes. A 3D printer system is described having, for example, five degree-of-freedom (5DOF). The 5DOF printer may be used to perform any of the methods described herein and combinations of the methods.

Abstract: A shape can be 3D printed by advancing a continuous length of material past a cutting head, cutting the material along one or more paths, providing adhesive on a surface of the material, and spirally winding the material onto a spool, such that the cut paths on each layer of the spiral are in alignment according to the 3D printed shape. A 3D printing system includes a material infeed configured to provide a supply of sheet material, a cutting head for cutting the material, a glue applicator, and a gathering spindle configured to rotate such that the material is spirally wound onto the spindle.

Abstract: A fast and economical system and methods directed to low-fidelity fabrication of three-dimensional (3D) objects using 3D printing. The invention facilitates rapid prototyping by providing a wireframe structure in the form of the underlying design structure of a 3D model, which may be useful for a variety of reasons including to provide a prototype preview that may be used for design validation of a 3D model.

Abstract: Pen and computing device sensor correlation technique embodiments correlate sensor signals received from various grips on a touch-sensitive pen and touches to a touch-sensitive computing device in order to determine the context of such grips and touches and to issue context-appropriate commands to the touch sensitive pen or the touch-sensitive computing device. A combination of concurrent sensor inputs received from both a touch-sensitive pen and a touch-sensitive computing device are correlated. How the touch-sensitive pen and the touch-sensitive computing device are touched or gripped are used to determine the context of their use and the user's intent. A context-appropriate user interface action based can then be initiated. Also the context can be used to label metadata.

Abstract: A grip of a primary user on a touch-sensitive computing device and a grip of a secondary user on the touch-sensitive computing device are sensed and correlated to determine whether the primary user is sharing or handing off the computing device to the secondary user. In the case of handoff, capabilities of the computing device may be restricted, while in a sharing mode only certain content on the computing device is shared. In some implementations both a touch-sensitive pen and the touch-sensitive computing device are passed from a primary user to a secondary user. Sensor inputs representing the grips of the users on both the pen and the touch-sensitive computing device are correlated to determine the context of the grips and to initiate a context-appropriate command in an application executing on the touch-sensitive pen or the touch-sensitive computing device. Meta data is also derived from the correlated sensor inputs.

Abstract: A pen-based user interface (PBUI) that facilitates input of a delimiter to a scope in a substantially uninterrupted stroke for generating a selection-action gesture phrase. Four delimiter techniques are provided, which include a Multi-stroke delimiter, a button delimiter, timeout delimiter and pigtail delimiter. The Pigtail delimiter uses a small loop to delimit the gesture. The delimiter techniques support integrated scope selection, command activation, and direct manipulation all in a single fluid pen gesture. The delimiter techniques can also be employed to terminate a complex scope consisting of a sequence of multiple pen strokes.
