摘要:
A portable writing apparatus includes a writing instrument carriage to hold a writing instrument and an actuator system coupled to the writing instrument carriage to move the writing instrument carriage. A controller is electrically coupled to the actuator system, and the controller includes logic that when executed by the controller causes the controller to perform operations including: receiving input data including a user's handwritten characters; and controlling the actuator system to move the writing instrument carriage in response to the input data. The writing instrument carriage traces a shape of the user's handwritten characters.
摘要:
A device including a housing, a writing tip connected to the housing, a writing surface position indicator, a processor in the housing, a memory device in the housing connected to the processor, and a sensor in the housing and cooperative with the writing surface position indicator. The device may be used to record writings and drawings applied to a surface by a user, to transmit that data to a remote device, to download data from remote devices, and to otherwise communicate with remote devices.

An image projection apparatus includes an image receiver; an image processor to convert an image signal to a projection signal; a projection unit to project a projection image on a projection screen; a coordinate calculator to calculate coordinates of a point on the projection screen when the point is identified by a coordinate input device; an interactive communication unit to communicate with the coordinate input device, and an external apparatus; a user direction detector to detect a user direction where a user that performs an operation of inputting the coordinates of the point exists based on the coordinates of the point input by the coordinate input device and coordinates defining an area of the projection screen; and a screen rotation determination unit to determine whether the user is performing the inputting operation and the projection screen is to be rotated based on the detected user direction.

摘要:
A state machine gesture recognition algorithm for interpreting streams of coordinates received from a touch sensor. The gesture recognition code can be written in a high level language such as C and then compiled and embedded in a microcontroller chip, or CPU chip as desired. The gesture recognition code can be loaded into the same chip that interprets the touch signals from the touch sensor and generates the time series data, e.g. a microcontroller, or other programmable logic device such as a field programmable gate array.

Embodiments include an apparatus, device, method, and computer program product. In an embodiment, a device includes a handheld writing device that includes a writing element, and a writing detector module operable to generate information indicative of a handwriting movement of the writing element. The device also includes a context detector module operable to generate information indicative of a content portion of a document proximate to the handwriting movement of the writing element.
摘要:
An optical text scanning device compatible with a small handheld computer such as a personal digital assistant (PDA). The scanning device allows for a clear view of the text that is scanned simultaneous to the scanning process so that the operator can continuously align the device to the text. The scanned images of the text are converted in real-time to standard byte or word characters for subsequent display on the computer's viewing screen. The operator can quickly verify the accuracy of the conversion by comparing the displayed character with the actual character of text on the surface that is being scanned. Scanned text characters are stored in standard digital text files for ease of manipulation.
摘要:
A data security system comprises a host processor, and a plurality of remote computers. Each remote computer provides biometric authentication of a user prior to responding to the user request for data access. The remote computers are handheld when in operational mode. A sensor in the handheld computer captures a biometric image while the remote computer is being used. The biometric sensor is positioned in such a way that the sensor enables the capture of the biometric image continually during computer usage with each request for access to secure data. The biometric authentication occurs in a seamless manner and is incidental to the data request enabling user identity authentication with each request to access secure data.
