Touchplates: low-cost tactile overlays for visually impaired touch screen users

Abstract

Adding tactile feedback to touch screens can improve their accessibility to blind users, but prior approaches to integrating tactile feedback with touch screens have either offered limited functionality or required extensive (and typically expensive) customization of the hardware. We introduce touchplates, carefully designed tactile guides that provide tactile feedback for touch screens in the form of physical guides that are overlaid on the screen and recognized by the underlying application. Unlike prior approaches to integrating tactile feedback with touch screens, touchplates are implemented with simple plastics and use standard touch screen software, making them versatile and inexpensive. Touchplates may be customized to suit individual users and applications, and may be produced on a laser cutter, 3D printer, or made by hand. We describe the design and implementation of touchplates, a "starter kit" of touchplates, and feedback from a formative evaluation with 9 people with visual impairments. Touchplates provide a low-cost, adaptable, and accessible method of adding tactile feedback to touch screen interfaces.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some users would not want to be dependent on additional physical objects to use their cellphones.

    “Even if costs were low, some users would not want to be dependent on additional physical objects in order to use their cellphones [8].”
  • Hybrid solutions require users to carry different overlays, which can be impractical.

    “Still, users would need to carry different overlays with them, which can be impractical.”
  • Hardware-only approaches rely on physical tools between screen and user; smartphones are not aware of overlays and do not adapt to their presence or absence.

    “Hardware-only approaches do not modify the underlying software; they rely on placing physical tools between the screen and the user. For instance, special plastic cases or screen overlays can delimit screen borders; however, smartphones are not aware of such overlays and do not adapt to their presence or absence [4, 8].”
  • Prior approaches regarding touchscreen use by blind users can be classified into three general categories: software-only, hardware-only and hybrid.

    “Prior approaches regarding the use of touchscreen by blind users can be classified into three general categories: software-only, hardwareonly and hybrid approaches [8].”
  • Increasing tactile feedback and tangible interaction on touchscreens can improve their accessibility.

    “Increasing tactile feedback and tangible interaction on touchscreens can improve their accessibility.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
