Abstract: Disclosed embodiments relate to processing of gestures to cause computation of measurements of a line using a touch screen. A system includes a processor, a touch screen coupled to the processor, a gesture module coupled to the processor for executing a gesturing method. The method includes determining a gesture shape and whether the gesture shape selects a first line segment by intersecting the first line segment. When the gesture shape selects a first line segment, it is then determined whether the gesture shape also selects an additional line segment different from the first line segment. When an additional line segment is not selected, the method calculates the length measurement from the beginning point of the segment to the end point of the selected first line segment. The method further displays the length measurement on a display.

Abstract: A method and a system for processing gestures to cause computation of measurements of an angle or a segment using a touch screen are disclosed. The system includes a processor, a touch screen coupled to the processor, and a gesture module coupled to the processor for executing a gesturing method. The method includes determining a gesture shape. For example, when the gesture shape is an arc or a line between two touching lines, the method calculates the measurement of the angle between the touching lines and behind the gestured line or arc. When the gesture is a line crossing a segment, the method calculates the measurement from the beginning of the segment to the end of the segment. The method further displays the calculated measurement of at least one of the angle or the segment.

Abstract: Structures within a service controller portion of a collaboration system collect and store content captured by a client service module operating within each collaborator's computing device. From commands received from a collaboration director's portable computing device, the service controller selects individual collaborator computing devices from which to capture screen content at selected rates. Collaborator content is sent to the director's portable computing device to be monitored by the director. Under command from the director's portable computing device, the service controller may also send collaborator content to a public display computing device. The collaboration director may designate one or more collaborative participants as “live presenter(s).” A live presenter's screen content may be captured and publicly displayed at higher frame rates and in real time in order to simulate a white board or slide presentation.

Abstract: A method and a system for processing gestures to cause computation of measurements of an angle or a segment using a touch screen. The system includes a processor, a touch screen coupled to the processor, a gesture module coupled to the processor for executing gesturing method, the method includes determining a gesture shape, when the gesture shape is an arc between two touching lines, calculating the angle between the touching lines behind the gestured line or arc, when the gesture is a line crossing a segment, calculating the measurement from the beginning of the segment to the end of the segment, and displaying the calculated measurement of at least one of the angle or the segment.

Abstract: A window is displayed on a display device. The window includes at least first and second portions thereof. In response to a user selecting the first portion of the window on the display device, a first set of keys are displayed on the display device. The first set of keys are operable by the user to specify a first type of information within the first portion of the window. In response to the user selecting the second portion of the window on the display device, a second set of keys are displayed on the display device. The second set of keys are operable by the user to specify a second type of information within the second portion of the window. The second type of information includes at least some information that is unsupported by operation of the first set of keys.

Abstract: A graphical object is displayed on a display screen of a student device. The student device may then display one or more data elements pertaining to the graphical object on a display screen of the student device. An expression entered by the student may then be displayed on the display screen of the student device. Variables in the expression may be determined by parsing the expression. A sequence of prompts is presented by the student device to associate each of the variables of the expression with one of the data elements. In response to each prompt, a data element is selected and associated with a variable in response to user input to the student device.
