| 20090140891 | LIGHT-SENSITIVE KEYBOARD - Certain embodiments of the invention provide a keyboard apparatus that may include an array of keys including a modifier key associated with one or more modifiable keys. Each modifiable key may include a main label and a secondary label. The secondary label may represent a function accessible by activating the modifiable key in combination with the modifier key. Further, the secondary label may include a light-reactive material visible only upon irradiation with light having a certain predefined wavelength. A light-emitting device may direct light having the predefined wavelength towards the array. A control element, however, may activate the light-emitting device only upon activation of the modifier key. In this manner, the light-emitting device may selectively illuminate the secondary label to assist a user in identifying and accessing the same. | 06-04-2009 |
| 20090184851 | Inputting information using holographic techniques - A method for inputting commands to a holographic input system, includes the steps of generating a virtual image of an input device by illuminating a hologram of the input device by means of a corresponding reference beam, the hologram being prerecorded on a holographic support; optically detecting a position of at least one actuator for operating the input device with respect to the virtual image of the input device; and issuing at least one command signal corresponding to the position of that at least one actuator as optically detected. The optical detection operation further includes providing at least one actuation hologram corresponding to the at least one actuator being placed at a specified position with respect to the virtual image of the input device, illuminating the at least one actuator with a beam, in order to obtain scattering into a corresponding object beam interacting with one actuation hologram through the corresponding object beam; generating a respective actuation detection beam through the interaction; and detecting the respective actuation detection beam to issue the command signal. | 07-23-2009 |
| 20090184852 | Optical joystick and portable electronic device having the same - An optical joystick and portable electronic device having the same are disclosed, by which malfunctions of the optical joystick due to sunlight or external illumination light are prevented or minimized. Therefore, precision of the optical joystick can be enhanced. The optical joystick according to the present invention includes an infrared light source, a cover part having a contacting surface for a contact by a subject, a light-receiving part detecting the infrared ray, and an optical member provided on an light path of the infrared ray traveling from the cover part toward the light-receiving part, wherein the cover part comprises a cover base and an infrared ray pass layer blocking out external noisy light on a predetermined band and passing substantially a wavelength band of infrared rays. | 07-23-2009 |
| 20100073205 | PORTABLE ELECTRONIC DEVICE - A portable electronic device is provided. The portable electronic device includes a central processing unit, a projecting module electronically connected to the central processing unit, a virtual keypad projection module configured to project a virtual keypad on a surface, an infrared radiation generator configured to irradiate infrared light generally parallel with the virtual keypad and an infrared sensor module configured to receive infrared light reflected by fingers of a user pressing the virtual keypad and generate corresponding signals and then send the signals to the central processing unit for the central processing unit to produce commands corresponding to the pressed virtual keypads. | 03-25-2010 |
| 20100188270 | OPTICAL INTERRUPTING INTERFACE - Improved user interface methods and devices are provided. Some such devices are configured to detect a user's touch according to a localized diminution and/or interruption of guided optical signals. The devices may be configured for guiding light in a piece-wise contiguous array of optical blocks disposed on a flexible substrate. Alternatively, or additionally, the devices may be configured for guiding light along non-continuous optical fibers on a flexible substrate. These basic structures, or comparable structures, may be used to implement a wide range of tactile user interfaces. | 07-29-2010 |
| 20120032822 | CONTROL PANEL FOR A MEASURING DEVICE - A control panel for a measuring device with a housing and a control and inspection window. The control panel includes at least one optical key that is operable through the control and inspection window using a finger. The optical key includes a transmitting element and a receiving element. The control panel is constructed such that it allows reliable and quick control even when the housing is open and the control panel is exposed. Specifically, the control panel has at least one corresponding finger-operable mechanical key in addition to the finger-operable optical key in order to reliably and quickly control the measuring device when a predefined control distance for the optical key is no longer ensured by the control and inspection window of the housing. | 02-09-2012 |
