Case Study 1: Self-Order Kiosk
Self-Order Kiosks
Self-Order are self-service touchscreen systems used for ordering food. They are primarily designed for fast, visual interaction, emphasizing efficiency and simplicity in the ordering process.
However, these kiosks often lack alternative input methods and adaptable physical designs, which can create accessibility challenges for some users.
Issue Overview
Fixed kiosk height
No voice command or audio prompts
Complex multi-step ordering
Who Is Affected?
Mobility-Impaired Users
Mobility-Impaired wheelchair users struggle with high-mounted screens and small touch targets.
Cognitive Disabilities
Users with cognitive impairments get overwhelmed by multi-step processes and unclear instructions.
Visually Impaired Users
Difficulties arise when interfaces lack high-contrast elements and proper screen reader support.
Older Adults and Seniors
Seniors who are not familiar with modern self-service technology find the system intimidating and confusing.
What Can Be Done?
Lower the touchscreen to the bottom half of the kiosk and include arrow-touchscreen buttons for easier navigation.
Ensure users can move through options using arrow controls on the bottom and select items.
Build the kiosk so that the operable parts (e.g., touch screen, buttons) are installed at a fixed, ADA-compliant height, ensuring that the top of these parts is no more than 48 inches above the floor.
Add arrow buttons that provide voice guidance, offering audible cues to navigate both the digital interface and physical elements.
Include a headphone jack, like ATMs, for private audio access and improved usability.
Manufacture and deploy only accessible kiosks that meet or exceed ADA and inclusive design standards, ensuring equal access for all users.

Case Study 2: Online Ticketing Websites
Online Ticketing Websites
Online ticketing websites allow users to purchase event tickets through interactive platforms.
However, many rely on highly visual, dynamic interfaces that can be challenging for a diverse user base. Complex seat maps, rapid checkouts, and visual clutter may hinder usability for many.
Issue Overview
Visually complex seat maps: Relying solely on graphics without accessible text alternatives.
Overwhelming visual clutter: With small clickable areas and non-linear navigation.
Fast-paced checkout processes: Requiring rapid interactions that can overwhelm users.
Who Is Affected?
Individuals have challenges with small or densely packed clickable areas, making precise selections difficult.
Mobility-Impaired Users
Users with cognitive impairments can be overwhelmed by countdown timers and increase pressure.
Cognitive Disabilities
Struggle with dynamic, image-based seat maps that lack text alternatives and clear labels.
Visually Impaired Users
Seniors who are not familiar with modern self-service technology find the system intimidating and confusing.
Older Adults and Seniors
What Can Be Done?
Provide an accessible list view with text-based seat options, allowing users to navigate easily with a keyboard or assistive technologies.
Include filters for price, section, and accessibility features to simplify selection and ensure equal access.
Streamline steps and remove unnecessary time pressure with adjustable countdowns.
Deploy a fully accessible online ticketing platform that empowers all users with seamless, intuitive, and independent access.
