| 20090115797 | Image Drawing Method, Portable Terminal, and Computer Program - An image drawing method for drawing an image on an input screen of a portable terminal having input keys arranged in an N×M matrix includes the steps of: determining a size of an input window formed of grid squares arranged in an N×M matrix; determining a position of the input window on the input screen; displaying the input window of the size determined in the input window size determination at the position of the input screen, the position being determined in the input window position determination; and in response to user input being performed on one of the input keys arranged in the N×M matrix, performing a drawing process at the grid square corresponding to the position in the N×M matrix at which the user input has been performed. | 05-07-2009 |
| 20100085169 | User Interface Feedback Apparatus, User Interface Feedback Method, and Program - A user interface feedback apparatus includes an operable element, a sensor, a processing unit, and a tactile control module. The operable element has a two-layer structure made up of a conductor and an insulator. The sensor detects, in the form of user contact information, at least a user contact position with respect to the insulator of the operable element. The processing unit acquires the detected information from the sensor, and determines parameters for an electrical signal to be output to the conductor. The tactile control module controls the frictional force between the insulator and the user by outputting to the conductor an electrical signal regulated by the parameters determined by the processing unit. | 04-08-2010 |
| 20110248962 | INFORMATION PRESENTING DEVICE, TACTILE SENSE PRESENTING METHOD, AND PROGRAM - An information presenting device of present invention includes a conductive layer to which an AC voltage is applied, an insulating layer for covering the conductive layer and presenting a tactile sense when a part of a body of a user set to a ground potential is in contact with the insulating layer. | 10-13-2011 |

| 20110248773 | System And Method For Sensing Human Activity By Monitoring Impedance - A system for sensing human activity by monitoring impedance includes a signal generator for generating an alternating current (AC) signal, the AC signal applied to an object, a reactance altering element coupled to the AC signal, an envelope generator for converting a returned AC signal to a time-varying direct current (DC) signal, and an analog-to-digital converter for determining a defined impedance parameter of the time-varying DC signal, where the defined impedance parameter defines an electromagnetic resonant attribute of the object. | 10-13-2011 |
| 20110248837 | Generating Virtual Stimulation Devices and Illusory Sensations Using Tactile Display Technology - Systems and methods providing tactile displays that present two-dimensional moving tactile stroke sensations are described herein. Systems and methods provide for controlling the characteristics of stimulation devices arranged in a grid topology to generate virtual stimulation devices and illusory sensations. Embodiments provide for the generation of illusory sensations including, but not limited to, continuous linear movement and shapes such as curves, squares, and circles. According to embodiments, a tactile display apparatus is provided that facilitates user interaction with the tactile display. The tactile display apparatus includes an interface embedded with stimulation devices and a control device that controls the operation of the stimulation devices to generate illusory sensations. | 10-13-2011 |
| 20110248913 | MOTIONBEAM INTERACTION TECHNIQUES FOR HANDHELD PROJECTORS - An image projection system may be configured to project objects which respond to movements and gestures made using a handheld projector, as well as to methods for controlling the projected objects based on such user input. For example, users may interact with and control objects in a projection frame by moving and/or gesturing with the handheld projector. Further, objects or characters projected using the handheld projector may be configured to perceive and react to physical objects in the environment. Similarly, elements of the physical environment may be configured to respond to the presence of the projected objects or characters in a variety of ways. | 10-13-2011 |
