    Abstract: A Braille block for use by the blind is disclosed. The Braille block includes a block body having a plurality of core holes, and a plurality of Braille cores selectively inserted into the core holes to transliterate desired letters into Braille characters. The Braille cores include short Braille cores and long Braille cores. When the long Braille cores are inserted into the core holes, they project from the surface of the block body. However, when the short Braille cores are inserted into the core holes, they do not project from the surface of the block body. Thus, the abrasion on the Braille blocks is concentrated on the Braille cores, so that the abraded Braille blocks can be renewed by changing only the abraded Braille cores with new ones. Further, when an existing Braille block breaks, only the broken Braille block can be changed with a new one.

  • Patent number: 7316566
    Abstract: System and method to enable blind people to detect and access hyperlinks within Braille documents. A proximity sensing foil placed under a Braille page senses the position of a reader's fingertips and provides coordinates of the sensed position. A workstation computes the distance between the sensed position and the predefined positions hyperlinks the page is known to contain, which are initially stored in a hyperlink table. When the user's fingertips are positioned over a hyperlink, the computed distance is less than a threshold value, in which case an acoustic signal alerts the user that a hyperlink is present. The user may then access the hyperlink.

  • Patent number: 6990435
    Abstract: A system for detecting tactile information includes strain-gauge touch sensors and a controller. Based on the sum output from each of tough-sensor sensor units, an analyzer in the controller calculates touch force Fi(t) at each measurement point. An automatic gain control adjusts the voltage amplitude Ai(t) of a sine wave of frequency fi applied to the sensor units at each measurement point to bring the voltage amplitude measured at each measurement point in line with a target voltage. The adjusted voltage Ai(t) is applied to the bandpass filter with a composite sine wave y(t) which includes sine waves of each frequency corresponding to the adjusted voltage amplitude Ai(t). This makes it possible to reduce the number of lines between the controller and touch sensors that includes numerous measurement points, and enables the gain of the touch sensors constituted by strain gauges to be controlled within an appropriate range.

    Abstract: A tactile display system includes a housing containing a tactile pin movable axially transverse of a reference surface and an actuator mechanism engageable therewith for selective movement between raised and lowered positions. An elongated electromagnet distant from the reference surface is aligned with the tactile pin and has spaced poles of opposite, selectively reversible, polarity. A generally spherical rotatable positioning member being a permanent magnet having a peripheral surface which is partially a spherical surface and partially a truncated surface has an axis of rotation coaxial with the tactile pin and the electromagnet and is responsive to operation of the electromagnet, being movable between a first position at which the spherical surface faces the tactile pin, causing positioning of the tactile pin at the raised position and a second position at which the truncated surface faces the tactile pin causing positioning of the tactile pin at the lowered position.

  • Patent number: 6700553
    Abstract: A tactual computer monitor includes rows and columns of rectangular cells. Each cell includes four rows and two columns of movable pins which are felt and read by a blind person. The pins are driven by electromechanical impact drivers and are held in position by resilient elastomeric cords. The impact drivers are carried on a bi-directional printhead which travels beneath the movable pins. An erasing mechanism is provided to positively drive the pins downwardly to erase the characters produced by the printhead.

  • Patent number: 6693516
    Abstract: A tactile transducer is able to provide a tactile display or serve as a tactile input sensor. Paired contactors having contactor tips separated by a gap are connected to transducer means (an actuator or sensor). Variations in the gap distance can create a tactile experience through skin stretch, or provide tactile input in sensor mode.

  • Patent number: 6692255
    Abstract: A refreshable Braille reader apparatus and method are disclosed, the apparatus preferably utilizing a rotating cylinder having endless rows of openings defined therethrough to a display surface with a pin held in each opening and freely movable therein. Static actuators at least equal in number to the rows of openings through the cylinder are maintained at a station adjacent to the surface of the cylinder, and are configured and positioned so that the pins are selectively contactable at either of their ends by different ones of the actuators during cylinder rotation in either forward or reverse direction thereby selectively positioning first ends of the pins relative to the surface of the cylinder to allow streaming of Braille text across a display area in either forward or backward order depending upon selected direction of cylinder rotation.

  • Patent number: 6650338
    Abstract: The methods and systems of the present invention receive video or image data, for example via television broadcast, cable, or satellite television signal, or directly from a video player, and process the data to determine the geometry and material properties of various objects represented in the video image. Geometry and material property information may be deciphered from a video image by reference to various fixed data sources and/or the application of known methods for elucidating such information from video or image data, such as shape-from-motion or shape-from-shading techniques. Alternatively, all or some of this information may be provided to the system together with the video or image data via a preconfigured side channel. The system coordinates and assembles the image data with the data relating to geometry and material properties of the objects and provides a realistic haptic interaction with those objects to the user.

  • Patent number: 6639510
    Abstract: A tactile reading system and a communication device for tactile data reading and input with a computer. It includes a set of sensitive means (13, 13′) located each in the proximity of or inside the input means (12, 12′) and arranged such that they can, under the control of the computer, communicate a binary sensation on each one of the user's finger. To each combination of simultaneous detection of sensations on the fingers, corresponds a read character, the character being the same as the one transmitted by the computer under the simultaneous action on the input keys associated with the active reading keys for the combination concerned. The invention is particularly designed for blind people.

  • Publication number: 20030073058
    Abstract: Single dot tactile reading module including a tactile dot, driven by a rotation of a cam around its axis, either directly or through a pair of levers. A shape memory alloy wire is attached on one hand to a rod which ends can slide in slots cut in internal faces of the cam, on the other hand to a rod held in a fixed position at the bottom of the tactile module. The wire contraction, produce by Joule heating, rotates the cam which in turn moves the dot up or down depending on the direction of the rotation. The wire cooling, accelerated by a heat sink allows the return of the wire to its initial length with help of a spring which pushes the rod from one end to the opposite end of the slots the cam being prevented from rotating by a locking spring having two stable positions, one corresponding to the up position of the dot, the other to its down position.
