Abstract
Braille writing devices and systems, and corresponding methods of writing braille characters on a tape medium are described herein. The devices and systems emboss tactile dots on different types of tape medium to enable braille character writing and advance the tape medium to create accurate and repeatable spacing of the braille characters. The devices and systems may be comprised of simply molded plastic parts that snap together using elastically averaging precision alignment features.
Claims20
A user input device comprising:
- a housing that defines an internal cavity of the device and includes a tape exit port;
- a plurality of arms disposed on a top surface of the housing;
- an embossing arm structure that is disposed within the internal cavity, the embossing arm structure comprising embossing arms projecting inwards, each embossing arm having a tip, where the embossing arm tips are configured to form a grid comprising six tips;
- an embossing anvil that is disposed within the internal cavity, the embossing anvil comprising concave features configured in a grid corresponding the configuration of the embossing arm tips;
- and
- a tape advancement structure disposed within the internal cavity of the device that is operable to advance a tape medium between the embossing anvil and the embossing arm tips to the tape exit port.
A user input device, comprising:
- a housing that includes a tape exit port;
- an embossing arm structure, comprising embossing arms, within the housing, and wherein each embossing arm tapers to an embossing arm tip, and wherein the embossing arm tips of the embossing arms form a grid of at least six tips;
- an embossing anvil, within the housing, wherein the embossing arm tips align with concave features arranged in a grid on the embossing anvil;
- a tape advancing structure, the tape advancing structure comprising a ratchet drum with notches that are operable to engage a pawl to advance the tape medium.
A user input device, comprising:
- a housing, the housing further comprising;
- an embossing arm structure within the housing, comprising embossing arms projecting inwards, and wherein each embossing arm tapers to an embossing arm tip, and wherein the embossing arm tips of the embossing arms form a grid of six tips;
- an embossing anvil, within the housing, wherein the embossing arm tips align with concave features arranged in a grid on the embossing anvil;
- and
- a tape handling structure within the housing, wherein the tape handling structure is capable of accepting a tape medium, wherein the tape handling structure is arranged to guide the tape medium between the embossing anvil and the embossing arm tips to the tape exit port, and wherein the flexural button arms, embossing arms, and embossing anvil are arranged such that depressing the flexural button arms causes coupling of the embossing arm tips and the concave features of the embossing anvil.
