Touchscreen use has become increasingly common in everyday devices. However, touchscreens pose a unique problem for blind and partially sighted individuals. It is particularly difficult for blind and partially sighted users to locate and select options on a touchscreen. Users are typically offered the opportunity to hear information as an alternative to touch-selecting options, such as having information vocalized. However, audible information is easily heard by others who are in proximity to the user and thus it is not secure for sensitive information. Vocalized confirmation is especially inappropriate for entry or confirmation of a Personal Identification Number (PIN).
In various embodiments, methods and systems for locating and activating on-screen controls without using visual identification presented.
According to an embodiment, a tactile strip is provided. Specifically, a tactile strip includes a back side configured to be coupled to a touchscreen display and a front side opposite the back side. The tactile strip includes a plurality of tactile features on the front side, the plurality of tactile features corresponding to a plurality of displayed inputs on the touchscreen display.

The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
A Self-Service Terminal (SST) may be used by a variety of users who may require differing features. An SST may include a touchscreen display without a keypad. This type of SST may be more difficult for blind and partially sighted users to access without additional accommodation. Tactile features may be used with the touchscreen to guide users to enter correct numbers, instructions, menu selections, or the like.
A touchscreen display for an SST may be difficult to navigate without audio feedback, which may not be appropriate or may not be available when entering secure information. For example, a SST may include an Automated Teller Machine (ATM). A user may wish to enter a Personal Identification Number (PIN) at the ATM to withdraw cash in association with a particular debit or identification card. Certain standards may apply to ATMs or other SSTs when a PIN is involved. For example, the ATM or SST may need to follow the Payment Card Industry PIN Transaction Security Point of Interaction Modular Security Requirements (e.g., version 4.0 or later), from June 2013. Audible prompts or specifically vocalized confirmations of selections may not satisfy these or other security requirements. A tactile feature may be used to guide a user to selections in a secure manner.
In an example, the tactile strip 100 may include a short groove 106. The short groove 106 may correspond to a menu entry on a touchscreen display. The short groove 106 may have a label 108. The label may be a tactile feature itself, such as a raised letter, number, word, braille, marking, abstract symbol, dot, etc. In another example, the label may be located in other places nearby, on, in, or around the short groove 106. For example, the label may be in the groove, above the groove, to a side of the groove, around the groove, or the like.
The tactile strip 100 may include a reference nub 110. The reference nub 110 may be used as a reference point in the plurality of grooves to indicate a predetermined number or selection, such as five. For example, the tactile strip 100 may include grooves corresponding to numbers arranged from the groove 102 as a starting point to the last groove before the short groove 106, with the numbers arranged in order from one to nine and the last groove assigned number zero. In this exemplary embodiment, the reference nub 110 may be at a groove corresponding to the number five. Other arrangements and corresponding menu items, numbers, selections, options, or the like may be used, with the reference nub 110 corresponding to any predetermined input.
The tactile strip 100 may include a back side (not shown) configured to be coupled to a touchscreen display. The back side may be coupled to the touchscreen display using double-sided tape, glue, other adhesives, a molding, embedding in a housing or the touchscreen display, screws, nails, or the like. In an example, the tactile strip 100 may include a front side opposite the back side. The front side and the back side may be connected by a left side, right side, top side, or bottom side. The sides other than the front and back sides may have a thickness, such as a thickness from a few hundred nanometers thick to a few dozen millimeters thick. In an exemplary embodiment, the tactile strip 100 may have a thickness within a few hundred nanometers above or below 0.7 millimeters. A tactile strip 100 with this type of thickness may include an adhesive strip. In another exemplary embodiment, the thickness of a tactile strip 100 may be a few dozen millimeters, such as in a plastic tactile strip. The thickness of the tactile strip 100 may vary along an axis. For example, the tactile strip 100 may taper up or down a vertical access. Grooves in the tactile strip 100 may have differing thicknesses from ridges, and both may have differing thicknesses from portions of the tactile strip 100 that are not grooves or ridges. A groove 102 may have a differing thickness from other grooves or a ridge 104 may have a differing thickness from other ridges. In another example, the short groove 106 may be separated from the other grooves by a raised broken line feature or a ridge of differing length or thickness to further separate the short groove 106 from the other grooves. In an example, the grooves or other tactile features may be arranged on a longitudinal axis of the front side or the tactile strip 100. In another example, the tactile strip 100 may not be at the same angle as the display. The tactile strip 100 may be slightly more reclined than the display to help with wrist articulation for ease of user access. Other angles may be included or mixed. For example, the a left number of grooves may be aligned at a first angle with respect to the display and a right number of grooves may be aligned at a second angle with respect to the display (e.g., two groups at different angles for ease of user access when using both hands to enter inputs).
In an example, the display 204 may not show the prompt 206 or the on-screen inputs 210A, 210B, 210N. For example, the display 204 may be black or blank, but may still allow the on-screen inputs 210A, 210B, 210N to be selected. For example, a user may select an option to blank the screen, but may still use the tactile features to guide a finger for selection of one of the numbered inputs.

In another example, the tactile strip 208 may be coupled, affixed, attached, or connected to the housing 202 or the display 204, or some other component of the SST 200 (e.g., the touchscreen, a support structure other than the housing 202, or the like). For example, the tactile strip 208 may be glued, taped using double-sided tape, screwed, or nailed to the housing 202, the display 204, or another part of the SST 200. In another example, the tactile strip 208 may be manufactured as a component piece of the housing 202 or display 204. For example the tactile strip 208 may include a plastic tactile strip extruded or molded with the housing 202 or the display 204. In yet another example, the tactile strip 208 may be coupled to a pre-existing SST 200 on the housing 202, the display 204, the touchscreen, or otherwise, (e.g., as an after-market or after-manufacturing addition).
In an example, a user may find a number by using a finger to follow a tactile feature on the tactile strip 208 to the on-screen input 210N. The user may indicate the number by touching the display 204 at the on-screen input 210N via the tactile feature on the tactile strip 208. In an example, the number may be selected by the user using a long press (e.g., the user holds a finger on the display 204 for a predetermined amount of time), a double touch (e.g., the user touches, releases, and touches the on-screen input 210N), or a touch on the on-screen input 210N and then at another place on the display 204. The SST 200 may generate feedback to indicate that a user has touched the display 204 or feedback to indicate that a number, menu selection, choice, option, confirmation, enter, exit, cancel, or clear has been selected. For example, the SST 200 may generate an audible tone to indicate a number has been selected. In another example, the SST 200 may generate haptic feedback (e.g., haptic pulse, vibrate, etc.) to indicate a selection. In another example the SST 200 may generate visual feedback (e.g., flash, colour change, additional visual elements that are presented and then disappear, etc.). In yet another example, the SST 200 may generate visual, audible and haptic feedback to indicate a selection. The selection may be a preliminary selection (e.g., an exploratory selection) or a final selection (e.g., an entered digit of a PIN).
