Abstract: Computerized methods and interactive input systems for manipulation of 3D objects are disclosed. An image of 3D object is displayed on a 2D interactive surface, and input is received and is interpreted for manipulating the 3D object. When the 3D object is selected, rotation control handles indicating available rotation directions are displayed. In one embodiment, the method comprises capturing images of a 3D input space, recognizing at least one object in the images, and comparing the recognized objects in the images to determine a difference therebetween based on a difference threshold. Depending on the outcome of the comparison, the recognized objects are emerged and associated with digital content, or only one of the recognized objects is maintained and associated with digital content.

Abstract: A computerized method of creating an irregular-shaped table of cells comprises detecting one or more cells of a table to be removed, removing each detected cell from the table and creating a table object representing the resultant irregular-shaped table.

Abstract: A system and method for facilitating user collaboration in real time are disclosed. The system comprises a network and a message queue service in the network that creates one or more message queues shared by multiple user computing devices for transmitting collaboration data between users.

Abstract: A method and a computing device for manipulating a graphical user interface (GUI) using camera are disclosed. The computing device captures images of a user by using a camera, detects the face image of the user from captured images, and detects at least one facial feature in the face image. The computing device analyzes at least one parameter of one or more facial features to determine gestures.

Abstract: A computerized method of recognizing an input hand-drawn table formed by freeform line objects comprises transforming each freeform line object of the table into one of a vertical line segment and a horizontal line segment, generating a grid system based on the vertical and horizontal line segments and converting the generated grid system into a table object.

Abstract: A participant response system (50) comprises processing structure (52) running an assessment during which participants are prompted to respond to one or more information requests. The processing structure executes a question authoring/editing facility to enable test question authoring that comprises a monitoring tool for monitoring questions during editing to inhibit creation of invalid questions. At least one display device communicates with the processing structure and is operable to display graphically authored test questions.
