The invention is based on a device (10) with a sensor, which is guided with one hand (20, 22) over a surface (14) and in which the data detected are displayed by a display unit (38). The invention proposes that grasping surfaces (40, 42) for the hand (20, 22) be positioned on two approximately diametrically opposed sides of a grip (12), at least one of which sides has a sensor (26, 28, 30, 32) that detects the number of fingers (20, 22) resting against this grasping surface (40, 42).

A method and apparatus for controlling and providing force feedback using an interface device manipulated by a user. A microprocessor is provided local to the interface device and reads sensor data from sensors that describes the position and/or other information about an object grasped and moved by the user, such as a joystick. The microprocessor provides the sensor data to a host computer that is coupled to the interface device by a communication bus that preferably includes a serial interface...

A sensing device for generating orientation data when positioned or moved relative to a surface, the orientation data being indicative of an orientation of the sensing device relative to the surface, the surface having coded data disposed upon it, the coded data being indicative, when sensed by the sensing device, of the orientation, the sensing device including: a housing; orientation sensing means configured to generate the orientation data using at least some of the coded data; and communicat...

A wireless communications device includes an antenna that receives a first signal at a first frequency and a second signal at a second frequency and converts the first and second signals into a composite signal. A first oscillator outputs a first oscillator signal at a first frequency and a second oscillator outputs a second oscillator signal at a second frequency. A demodulator receives the composite signal and the first and second oscillator signals. The oscillator signals are selected so that...

A presentation system and a user device for use as a presentation aid is disclosed. The system comprises presentation means (5) for presenting images that associate with a presentation. Pointer means (4) are used for provision of a pointer on an image (11) presented by means of the presentation means. Detector means (8) are for detecting the pointer on the image and for determining the location of the pointer relative to the image. Control means (6) are adapted to provide at least one control fu...

A lasso select tool that allows a user to draw a flexible line of selection ink in order to select one or more graphical objects for manipulation. As the user draws this selection line, the lasso select tool continuously redraws and displays a connection line connecting one end of the selection line with the opposite end of the selection line. This connection line thus graphically demonstrates to the user the area that is presently encompassed by the resulting lasso enclosure. Further, the lasso...

A handheld electronic device which is adapted to carry out at least one operation. The device is controllable by a user using the device as a pen and writing a command for initiating said operation, such as "dial the following telephone number".A method for initiating the operation in an electronic device and software used for implementing the method.

The invention relates to a signal source (S) which comprises a local oscillator (5) for generating a reference frequency signal fo. The signal source comprises: a frequency divider by N (6) connected to the local oscillator (5) and delivering two quadratic square-wave signals (Id, Qd) at a frequency fo/N,N being equal to 2 or 4.times.n, and n being an integer number, and a multiphase filter (7) which supplies two sinusoidal quadratic signals (Is, Qs) at a frequency equal to mfo/N on the basis of...

An apparatus for controlling the position of a screen pointer includes a movement sensor for sensing relative movement between the apparatus and a surface, and generating corresponding movement data. The movement sensor is configured to generate compressed data representing the movement data. The apparatus includes a wireless transmitter for wirelessly transmitting the compressed data.

A handwriting pen used in a tablet type handwriting entry device comprises a pen tip, a pen tip position sensor, and a pressure sensor. The pen tip position recognizer captures a main position coordinates as the pen tip taps on a tablet panel, and generates a main position data. The pressure generator senses a press by the pen tip on the tablet, and generates a pressure value. The handwriting pen connects to a main system by a signal transmission line, and the acquired information is transferred...
