Abstract: A classroom configuration is described that includes a computer having a wireless communications interface and a plurality of student workstations. The workstations each include a work surface, a projecting device mounted proximate the work surface and operable for projecting images onto the work surface, a light emitting device, a tracking device mounted proximate the work surface and operable for capturing the image projected onto the work surface and for tracking movement of the light emitting device, and a processing device communicatively coupled to the projecting device and the tracking device. The processing device includes an interface operable for communicating with the computer via the communications interface.

Abstract: A method and system for performing automated training environment monitoring and evaluation. The training environment may include a mixed reality elements to enhance a training experience.

Abstract: Providing methods and systems to quickly and accurately respond to a natural-language question. The responses to the question can depend on additional information about the user asking the question, and the subject matter of the question the user asked. For example, the system knows that the user understands French, and can supply French answers to the user. Such additional information can improve on relevancy of the responses to the question. More than one responses can be provided to the user to allow the user to pick the more appropriate one. One embodiment uses a computer with a database having many phrases and question formats. The computer identifies phrases in the question based on at least one grammatical rules and phrases in the database. Then the computer links the phrases to categories based on at least one semantic rule, the subject matter of the question, and information about the user, such as previous questions asked by the user.

Abstract: An electronic device includes: a key input section having a plurality of keys; a first display section for displaying a display data; a first display control section for controlling the first display section; a communication section for transmitting the display data to a display device, the display device being separable from the electronic device and including a second display section for displaying the display data and a second display control section for controlling the second display section; a main data memory for storing a main data; a table memory for storing a table of key names in association with the keys; a key name memory for storing, as a key name data, a key name retrieved from the table memory when a key corresponding to the key name is pressed; and a main control section for allowing the first display section and the second display section to display data which are stored in the main data memory and in the key name memory, via the first display control section and the second display control se

Abstract: An electronic device for displaying question data and answer data includes an input device for entering commands, first and second displays, and a processor. The question data is displayed on the first display which is visible to an operator of the electronic device and on a second display which is visible from a position from which the first display is not visible, i.e., the position of an observer such as a student. The operator can selectively control the displaying of the answer data on each of the displays using commands entered on the input device. Entry of a first command causes the answer data to be display only on the first display so that the answer is visible only to the operator. Entry of a second command causes the answer data to be displayed on the second display so that the observer can also see the answer. In one mode of operation, the question and answer data for many questions is stored in a storage device, and the questions are categorized by level of difficulty or by subject.

Abstract: A Method and System to teach a user a subject based on his questions. The system allows the user to control his learning process, and helps to fill in gaps of misunderstanding in the subject. In one embodiment, the system, including a database, presents study materials on the subject to the user. After working on the presented materials, the user enters his question into the system, which generates an answer to the question, and presents it to him. Then the system compares the question with one or more questions previously entered by the user to determine his understanding level in the subject. Based on the determination, the system may present to the user appropriate study materials. The user typically asks more than one question, and the process of answering his question by the system repeats.

Abstract: This invention provides automatic testing systems and methods for testing for figural responses to a test inquiry. The testing system includes a test sheet of predetermined dimensions having a grid with a plurality of marking areas arranged in predetermined position and a figural arrangement having a first optical reflectivity arranged within the grid corresponding to one or more of the marking areas. The system includes indicia of a second optical reflectivity overmarking a selected number of the marking areas associated with the figural arrangement and optical scanning means having different optical sensitivities to the first and second optical reflectivities for scanning the sheet to determine the positions of the overmarked areas.

Abstract: A cursor positioning device for a computer system having a projection display monitor including a screen. A light pointer in the form of an elongated housing is positioned with its tip at a selected location on the screen. A light sensor detects the raster scan trace and transmits a timed electrical signal to an interface, which determines the coordinates of the selected location for use by a computer in controlling the position of the cursor on the projection screen.

Abstract: Terminal trainer keyboard and display apparatus for teaching keyboard operations and knowledge items and skills, including a keyboard array of touch keys representing individual characters and keyboard operations each having a switch associated therewith, a visual projector to be located within view of the trainee having a viewing screen onto which lesson information is displayed projected from a training film having sensor activating code bars beside the film frames denoting the correct key location for the displayed lesson instruction. The keyboard includes a light emitter at each key for illuminating its associated key, and an electronic circuit is coupled to the switches and receives correct key location signals from the sensors detecting the code bars to activate correct and incorrect readout counters to indicate the number of correct and incorrect key activations and to activate the light emitter at the correct key location when a key at an incorrect location is activated.
