摘要:
A trajectory-estimation apparatus and method that can estimate the trajectory of a pen-type optical mouse in a pen-up state. The trajectory-estimation apparatus includes a timer module calculating time for which an optical input device moves in a first state of the optical input device that produces a trajectory, and a trajectory-estimation module estimating the trajectory of the optical input device in a period where a distance between the optical input device and a work surface exceeds a threshold value, based on at least one of the calculated time and a moving speed of the optical input device.

A three-dimensional (3D) pointing sensing apparatus may be provided. The 3D pointing sensing apparatus may include an image generation unit that may photograph a first light source and a second light source in a light emitting unit, and generate an image including an image of the first light source and an image of a second light source. Also, the 3D pointing sensing apparatus may include an orientation calculation unit that may calculate an orientation of the light emitting unit, using a size difference between the image of the first light source and the image of the second light source in the image.

A three-dimensional (3D) position estimation apparatus and method using ultrasonic signals may estimate a 3D position based on distances between two ultrasonic signal transmitters and an ultrasonic signal receiver, and direction angles where the ultrasonic signal receiver receives the ultrasonic signals. When the ultrasonic signal receiver moves on a fixed distance, the 3D position estimation apparatus and method may estimate the 3D position of the ultrasonic signal receiver based on the fixed distance and the direction angles where the ultrasonic signal receiver receives the ultrasonic signals.

A portable terminal having a motion detection function and a motion detection method for the portable terminal are provided. A motion of the portable terminal is input by measuring an acceleration along the X-, Y- and Z-axes of the portable terminal. A current posture of the portable terminal is calculated by calculating rotation angles along the X- and Z-axes with respect to the X- and Z-axes in a basic posture using the acceleration along the X-, Y- and Z-axes. The acceleration along each axis is converted to an equivalent basic-posture acceleration along each axis using the rotation angles. The detected motion of the portable terminal is recognized using the basic-posture acceleration along each axis.

A motion-recognition portable terminal and a motion recognition method therefor are provided. In the portable terminal, a motion key starts to create a motion entry, upon activation. A motion detector measures an acceleration along each axis of the portable terminal, upon activation of the motion key. A controller determines whether the motion entry has been completed based on the variation of the each-axis acceleration.

An apparatus and method for controlling a terminal is provided. A terminal control apparatus may set a virtual display space in an outer circumferential portion of the terminal and map at least one file to the virtual display space. Through this, a display region of the terminal may be expanded to an outer circumferential region of the terminal.

Provided is a mobile terminal having a sensor detecting movement thereof and an event processing method. The mobile terminal includes: an orientation detector for monitoring, in response to detection of an event, movement of the mobile terminal for a preset time duration to identify an orientation of the mobile terminal; and a controller for processing the event in an operating mode corresponding to the identified orientation. As a result, the user can readily switch operating modes of the mobile terminal by changing orientations thereof.

Disclosed are an apparatus and method of deducing a user's intention using multimodal information. The user's intention deduction apparatus includes a first predictor to predict a part of a user's intention using at least one piece of motion information, and a second predictor to predict the user's intention using the predicted part of the user's intention and multimodal information received from at least one multimodal sensor.

A three-dimensional (3D) space interface apparatus and method are provided. The 3D space interface apparatus provides an interface in which a user may directly touch and transform a 3D virtual object of a 3D space, which is shown in various ways depending on a position of the user. The 3D space interface apparatus may provide for manipulation of the 3D virtual object by the user using a sensing signal that senses the position and movement of a manipulation object the user. Specifically, an interface unit of the apparatus verifies, using the sensing signal, whether a predetermined movement of the manipulation object has occurred or whether a contact between the 3D virtual object and the manipulation object has been made, and generates a predetermined reaction corresponding to the predetermined movement or the contact.
