Project Overview

The National Federation of the Blind expressed accessibility concerns with respect to visually impaired users. This scope would create an accessible user experience (the “Inclusive Experience”) for the visually impaired as well as those with auditory and mobility impairments for both the web and kiosk environments.

Current users receive health assessment information through the kiosks located in Walmart Pharmacies and through the member website. Kiosk users utilize the kiosk independently or with the assistance of locally trained staff (i.e. pharmacists in store locations) or by contacting dedicated support service staff. Support services team can remotely walk a user through an assessment and provide real-time results to the user.

Project required new hardware and external accessibility experts to guide and teach technology and user experience team to design and implement accessible experiences. This project spanned two years, and consisted of studying user experience best practices with accessibility experts (one of which was totally blind).

Project Goals:

Mitigate accessibility issues for the following user types:

  • Low vision
  • Blind
  • Mobility Impaired
  • Hearing Impaired

Provide an “Inclusive Experience”:

  • Allow a user to launch an “Inclusive Experience” that will allow the user to access the kiosk capabilities of Blood Pressure, Weight and Vison Assessments with minimal interaction with the touch screen.

  • The Inclusive Experience will contain guided audio instructions that guide the user through the experience.

  • The Inclusive Experience allows the user to obtain Biometric Measurements (“Results”) by means of audio feedback (as opposed to onscreen display).

  • The Inclusive Experience includes the ability to navigate the experience using an assistive audio navigator tactile keypad. This assistive keypad device offers menu navigation by means of audio direction. Users with impaired vision, reading difficulties or impaired fine motor skills can navigate through menus or directories that would typically be presented on a visual display or touch screen. Screen content is presented and summarized by recorded or synthesized language via a headset or handset. Menu pages and available options can be scanned and selected using this responsive and highly tactile keypad device.

The Speech Output interface is enabled when a user connects their headphones to the audio jack on the tactile keypad. When in Speech Output mode, the kiosk may be operated by using the Audio-Nav keypad and, if the display is visible, via the touch screen. If the user blanks the screen, the touch screen will not be active. Screen blank can be turned on or off when the application opens or by selecting "Help" and navigating to the screen blank option.

The kiosk can be operated with the touch screen and/or the Audio-Nav keypad. This mode is enabled while the kiosk is displaying the attract screen by pressing any of the buttons in the diamond shaped keypad. This method of operation may assist users who lack fine motor control and are unable to use a touch screen. This mode requires displaying "visual focus" (a colored outline) on any on-screen element. This feature will help a user know which element among multiple elements has the keyboard focus.
