20080246635 | Handheld Electronic Device and Keypad Having Tactile Features - An improved handheld electronic device and keypad include tactile features that help a user to identify certain keys of the keypad In the present exemplary embodiment, the keypad includes keys in a predetermined region that can be employed during a telephone operation. The keypad additionally includes other keys outside the predetermined region. The keys in the predetermined region include tactile features that enable the user to identify and actuate the keys in the predetermined region during a telephone operation with the user directing minimal visual attention to the handheld electronic device. | 10-09-2008 |
20090153374 | VIRTUAL KEYPAD INPUT DEVICE - A compact input device for fast text input. Ten perimeter regions are defined in a decagon shaped ring on a touch pad, and nine more center regions arranged in a 3 by 3 matrix are defined at the center of the perimeter regions. In alphanumeric mode, each of the ten perimeter regions represents a numeral or a character of the same order, found on a corresponding key of the ten numeric keys, 0 to 9, found on a standard 12-key telephone keypad. All perimeter regions synchronously switch to another group of characters of the same order, in accordance with the direction of a swipe on any of the perimeter regions. A tap on a perimeter region selects the character represented by the region at the moment. In addition, it is capable of operating in a standard 12-key telephone keypad mode, pointing device mode, and symbol mode. | 06-18-2009 |
20110102205 | KEYPAD STRUCTURE - A keypad structure comprises a plurality of dome switches. Each of the plurality of dome switches provides a first tactile feedback to a user when pressed. At least one vibratory element is electrically connected to the dome switches to actuate when one of the plurality of dome switches is pressed. The at least one vibratory element provides a second tactile feedback to the user. | 05-05-2011 |
20110148671 | CURVE-SHAPED TOUCH-SENSITIVE KEYBOARD - A curve-shaped touch-sensitive keyboard comprises a keyboard casing in form of a curve surface, in which upper and lower ends of the keyboard casing are warped upwards along a whole length of the keyboard casing to form two convex sections and a concave section is formed between the two convex sections; a key region disposed on an upper surface of the concave section, in which the key region is composed of a plurality of keys and each of the keys is provided with a trigger sensor; and a printed circuit board provided within the keyboard casing, in which a plurality of electronic sensors are mounted on the printed circuit board and each of the electronic sensors corresponds to one of the keys. With the present keyboard, accidental touches on the keys could be avoided effectively. | 06-23-2011 |
20110227763 | Haptic Keyboard Assemblies, Systems and Methods - Various embodiments provide keyboards that utilize electrically-deformable material as an actuating mechanism to provide haptic feedback to a user of the keyboard. In at least some embodiments, the electrically-deformable material is utilized to impart, to a depressed key or keyboard element, a multi-vectored movement that produces a perceived acceleration of the key or keyboard element thus providing a user with haptic feedback which simulates a snapover movement. | 09-22-2011 |
20120112933 | KEYBOARD - A keyboard includes a stiffener having a plurality of recesses defined therein, a flexible printed circuit defining a plurality of venting holes, each venting hole in correspondence with one of the plurality of recesses, and a dome sheet provided on top of the flexible printed circuit and including a plurality of domes, each of the domes in correspondence with one of the plurality of venting holes. | 05-10-2012 |
20130015985 | Backlit Haptic Key - Various embodiments provide keyboards that utilize electrically-deformable material as an actuating mechanism to provide haptic feedback to a user of the keyboard. In at least some embodiments, the electrically-deformable material is utilized to impart, to a depressed key or keyboard element, a multi-vectored movement that produces a perceived acceleration of the key or keyboard element thus providing a user with haptic feedback which simulates a snapover movement. In at least some embodiments, a light source can be mounted or otherwise positioned relatively close to and beneath the top surface of one or more keys or keyboard elements to backlight a portion or portions of a keyboard. | 01-17-2013 |
20140203953 | TABLET COMPUTER WITH INTEGRATED TACTILE KEYBOARD - A mobile electronic device such as a tablet computer is provided having flexible display panel that deforms in response to the application of pressure thereto. The tactile response of the display panel is affected by underlying structures. A bottom layer, which may be rigid, is positioned beneath, parallel to and spaced away from the flexible display panel. Elastic diaphragms or elastic bodies can be interposed between the display panel and bottom layer. A guidance matrix, which may be rigid, can be further interposed between the display panel and bottom layer, such that pressure applied to the display panel results in localized downward deformation in the area of a guidance matrix cavity. The elastic diaphragms or elastic bodies may extend into the guidance matrix cavities. These subsurface structures may be utilized to provide variable tactile response corresponding to the locations of keys on a virtual keyboard displayed on the display panel. | 07-24-2014 |
20140375481 | KEYPAD - A keypad is described. The keypad comprises: a keypad housing defining a plurality of key apertures; a plurality of physical keys, each physical key located in a respective key aperture and being moveable with respect to the key aperture; and a non-contact (for example, capacitive) sensing layer located beneath the plurality of keys. A touch controller is coupled to the capacitive sensing layer and is operable to ascertain a touch location corresponding to a depressed key. A cryptographic controller may be provided in communication with the touch controller and is operable to interpret the touch location. | 12-25-2014 |
20150102947 | FILM-TYPE HAPTIC DEVICE, HAPTIC FEEDBACK ELECTRONIC DEVICE AND HAPTIC KEYBOARD - There is provided a film-type haptic device including: a plate shaped base plate; at least one spacer provided on an edge of an upper surface of the base plate; an actuator including a film shaped polymer layer positioned on the spacer and supported by the spacer and first and second electrodes provided so as to closely and entirely cover both surfaces of the polymer layer, respectively; and an elastic plate adhered to an upper surface of the actuator. The film-type haptic device according to the present disclosure may significantly decrease consumption power consumed in vibration and allow a user to more accurately feel haptic sensation for touch input. | 04-16-2015 |
