Abstract: In various implementations, a computing device is configured to provide a live preview of salient contours generated on a live digital video feed. In particular, a designer can use a computing device with a camera, such as a smart phone, to view a real-time preview of salient contours generated from edges detected in frames of a live digital video feed prior to capture, thereby eliminating the unpredictability of salient contours generated from a previously captured image. In some implementations, the salient contours are overlaid on a greyscale conversion of the live digital video feed for improved processing and visual contrast. Other implementations modify aspects of edge-detecting or post-processing filters for improved performance on mobile computing devices.

Abstract: Embodiments of the present invention provide systems, methods, and computer storage media directed to a touch digital ruler. As such, a particular drawing stroke on a canvas or background can be drawn in alignment with a template irrespective of whether a touch path input by a user aligns with the template. In some implementations, a drawing stroke is aligned with a template edge when the touch digital ruler has been activated despite the location of a user's motion on a touchscreen display.

Abstract: An input device, such as a multifunction straight edge or a keyboard, has a recognizable contact shape when placed on a touchscreen display surface of a computing device. The contact shape of the input device can be a defined pattern of contact points, and a location and orientation of the input device on the touchscreen display surface is determinable from the defined pattern of the contact points. The input device includes an interaction module that interfaces with a companion module of the computing device. The companion module can initiate a display of an object responsive to the input device being recognized on the touchscreen display surface. The interaction module can receive a user input to the input device, and communicate the user input to the companion module of the computing device to modify the display of the object on the touchscreen display surface.

Abstract: A gesture is performed by a wireless accessory attempting to pair with a device. The gesture comprises a series of user interactions associated with accessory data detected at the accessory and device data detected at the device. The device begins looking for accessories advertising a Bluetooth service indicating they are attempting to pair. Once an accessory is identified, the device compares the device data to the accessory data for that particular accessory. If the accessory data matches the device data, the gesture detected at the device was made by the accessory and a secure connection can be established. Based on the secure connection, a clock associated with the accessory may synchronize with a clock associated with the device for additional security and fidelity.

Abstract: Embodiments of the present invention relate to a portable charging case that can serve as both a charging base and a protective carrying case for a rechargeable stylus. The portable charging case can enable a quick connect and release of the stylus using magnetic force for magnetic engagement of the stylus to the charging base. The charging base may include a logic board that dynamically changes the polarity of the charge coming in through the charging base charging contacts. Such a dynamic change of polarity can recharge the stylus irrespective of the polarity alignment between the stylus charging terminals and the charging base charging contacts.

Abstract: An input device for providing inputs to a computing device includes an enclosure having a top, a bottom, and at least three sides such that the top and bottom have a polygonal shape. The top includes a trackpad substantially centered on the top surrounded by buttons at the corners of the top. In particular, a button is provided at each corner on the top of the device. The trackpad provides for touch input while the buttons may be mapped to shortcut keys for providing input to a paired computing device.
