摘要:
Systems and methods provide for gesture-based creation of interactive hotspots in a real world environment. A gesture made by a user in a three-dimensional space in the real world environment is detected by a motion capture device such as a camera, and the gesture is then identified and interpreted to create a “hotspot,” which is a region in three-dimensional space through which a user interacts with a computer system. The gesture may indicate that the hotspot is anchored to the real world environment or anchored to an object in the real world environment. The functionality of the hotspot is defined in order to identify the type of gesture which will initiate the hotspot and associate the activation of the hotspot with an activity in the system, such as control of an application on a computer or an electronic device connected with the system.

An audio device management system (ADMS) manages remote audio devices via user selections in video links. The system enhances audio acquisition quality by receiving and processing human suggestions, forming customized two-way audio links according to user requests, and learning audio pickup strategies and camera management strategies from user operations. The ADMS control interface for a remote user provides a multi-window GUI that provides an overview window and selection display window. The ADMS provides users with more flexibility to enhance audio signals according to their needs and makes it more convenient to form customized two-way audio links without requiring users to remember a list of phone numbers. The ADMS also automatically manages available microphones for audio pickup based on microphone sound quality and the system's past experience when users monitor a structured audio environment without explicitly expressing their attentions in the video window.
摘要:
Techniques for generating a storyboard are disclosed. In one embodiment of the invention the storyboard is comprised of videos from one or more cameras based on the identification of activity in the video. Various embodiments of the invention include an assessment of the importance of the activity, the creation of a storyboard presentation based on importance and interaction techniques for seeing more details or alternate views of the video. In one embodiment, motion detection is used to determine activity in one or more synchronized video streams. Periods of activity are recognized and assigned importance assessments based on the activity, important locations in the video streams, and events from other sensors. In different embodiments, the interface consists of a storyboard and a map.

Techniques for generating action keyframes for a fixed-position camera based on the identification of activity in the video, an assessment of the importance of the activity, object recognition in the video, and interaction techniques for seeing more details of the video are presented. In different embodiments of the invention, the importance of activity is determined based on the amount of activity, important locations in the video streams, detected features such as faces, and events from other sensors.
摘要:
Systems and methods for determining the location of a microphone by using sounds played from loudspeakers at known locations. Systems and methods may thereby require a minimal level of infrastructure, using sounds that would naturally be played in the environment. Systems and methods may thereby allow devices such as smart-phones, tablets, laptops or portable microphones to determine their location in indoor settings, where Global Positioning Satellite (GPS) systems may not work reliably.
摘要:
Systems and methods for repeat photography and difference extraction that help users take pictures from the same position and camera angle as earlier photos. The system automatically extracts differences between the photos. Camera poses are estimated and then indicators are rendered to show the desired camera angle, which guide the user to the same camera angle for repeat photography. Using 3D rendering techniques, photos are virtually projected onto a 3D model to adjust them and improve the match between the photos, and the difference between the two photos are detected and highlighted. Highlighting the detected differences helps users to notice the differences.
