This case study focuses on the application of psychological principles to enhance the usability and functionality of the existing self-serve kiosks at various City of Toronto public offices.

THE PROBLEM CONTEXT

The City of Toronto has set up multiple accessible public service counters, including those in civic centers throughout the city. These counters are open to the public and provide a range of services, including information retrieval, fine payments, and ticket dispute resolution. While online alternatives exist for these services, these physical centers primarily serve individuals who encounter challenges when using online services or have specific accessibility needs.

To utilize the services at these centers efficiently, the existing Queue Management System (QMS) allows people to book appointments in two ways: by visiting the city's online portal or through a designated phone line. Individuals arriving at the civic centers with an appointment can check-in using the digital kiosk. For those without an appointment, they can reserve a time slot at the kiosk if available.

The existing QMS involves three main user touchpoints: the digital kiosks, the tickets printed by the kiosks, and the screen displaying the ticket numbers. These touchpoints work together to streamline the process and ensure that everyone receives timely and effective service.

Imagine if you had to carry your smartphone's user manual every time you wanted to perform basic tasks like sending a message or making a call. Similarly, adding an additional instruction sheet above the kiosk would only increase the user's cognitive load, making it more difficult to read, interpret, and follow the instructions.

The current kiosk home screen

The current home screen lacks a clear visual indication of the primary action, requiring users to invest more cognitive resources to identify the important action. This adversely affects the usability of the interface. Additionally, with limited touch areas and no visual cues, users find it challenging to navigate through the interface.

The redesigned screen aims to empower users in making informed decisions by providing more information and facilitating navigation through visual cues. The principles of the Law of Common Region, Visual Hierarchy, and Fitt's Law have been applied to reduce cognitive load, enabling users to interpret information quickly and take appropriate actions.

🧠

PSYCHOLOGY INSIGHTS

Personalization

"Hi, Good Morning" on the digital kiosk welcome screen can improve the user experience based on the personalization principle by creating a sense of warmth and familiarity. By using a friendly and personalized greeting, the digital kiosk can establish a more human-like interaction, making users feel welcome and valued. This simple act of personalization can enhance the overall user experience and encourage users to engage more willingly with the kiosk's services.

Recognition

The recognition principle suggests that using familiar and easily recognizable symbols or icons can improve user understanding and interaction with a system. By using familiar symbols to represent functions and actions, icons provide visual clarity and faster comprehension. Their language independence makes them universally understandable, catering to users of diverse backgrounds.

Fitt's Law

The law states that bigger targets are easier and quicker to select. Implementing larger buttons reduces errors, enhances accessibility, and creates a smoother interaction, leading to a more satisfying user experience overall.

The paper with ticket number

THE PRINTED TICKET
The current kiosk home screen

After receiving the printed ticket with a number, the user eagerly waits for their number to be called. Based on field studies, it was observed that when ticket numbers with similar characters, such as 0, O, 1, I, are called, users tend to immediately proceed to the counter, assuming it is their number. However, in most cases with similar characters, they misinterpret ticket numbers, which is caused by confirmation bias. Additionally, for many users, it seems difficult to decipher the ticket number from the pool of other information.

To tackle the confirmation bias issue, distinct alphabets like M and E were used for ticket numbers. Additionally, the Von Restorff effect was employed, utilizing a contrasting background to aid users in recognizing the ticket number. Moreover, the visual hierarchy was simplified to ensure easy scanning through the ticket.

🧠

PSYCHOLOGY INSIGHTS

Confirmation Bias

When users see a number that resembles their ticket number, they may immediately assume it is theirs due to confirmation bias. This cognitive bias leads users to seek information that confirms their preexisting beliefs or expectations, even when the information may be ambiguous or misleading. As a result, users may prematurely approach the counter, thinking it is their turn, leading to potential confusion and delays in the service process.

Von Restorff Effect

By highlighting the ticket number, it stands out prominently from the rest of the details on the ticket. This distinctiveness grabs the user's attention, making the ticket number more memorable and easier to find amidst the surrounding information. By leveraging the Von Restorff effect, users can quickly and accurately identify their ticket number, reducing confusion and frustration.

Gestalt Principle

Applying the Gestalt principle to the printed ticket can greatly improve scannability through effective visual hierarchy. Proximity ensures that related details like the ticket number, timestamp, and counter information are grouped closely, facilitating quick identification. Similarity in fonts, colors, and formatting for related information creates visual patterns for easy comprehension. Closure, achieved through enclosing sections with lines or boxes, guides the user's eye smoothly across the ticket's content.
