Introduction

Human-Computer Interaction (HCI) has evolved significantly from the early days of computing, where interfaces were primarily technical and inaccessible to the general public. The design principles guiding user interfaces are crucial for ensuring ease of use, efficiency, and user satisfaction. Theo Mandel’s five golden rules of interface design provide a foundational framework for assessing and enhancing user interfaces. This paper explores three daily-used interfaces—smartphone touchscreen, online banking platform, and smart home thermostat—analyzing their adherence to Mandel’s principles, and suggesting improvements to optimize user experience.

1. Daily Interaction Interfaces

a. Smartphone Touchscreen Interface

The smartphone touchscreen is arguably the most frequently interacted interface today. It combines visual presentation with touch-based input, allowing users to navigate applications, make calls, send messages, and browse the internet seamlessly. The interface adheres well to some of Mandel’s rules, such as consistency and visibility, ensuring that users can easily understand and interact with their devices without deliberate effort.

b. Online Banking Platform

Online banking platforms have become essential for personal financial management. These interfaces provide users with access to account information, fund transfers, bill payments, and more. They prioritize clear information architecture and feedback mechanisms to guide users through complex financial transactions efficiently, aligning with Mandel’s rules on feedback and simplicity.

c. Smart Home Thermostat

The smart thermostat interface, such as Nest or Ecobee, offers users control over home temperature settings via mobile applications or physical controls. These interfaces aim to be intuitive with minimal user effort but vary in adherence to usability principles, especially regarding error prevention and flexibility.

2. Analysis of Interfaces in Relation to Mandel’s Golden Rules

a. Smartphone Touchscreen

This interface exhibits high consistency, with familiar icons and gestures across applications. Visibility of options is maintained by minimalist design, reducing clutter. However, sometimes the touch targets are too small, violating the rule that controls should be easily reachable. To improve, increasing touch target size and providing customizable gestures could enhance usability.

b. Online Banking Platform

The platform demonstrates a clear interface with logical flow, consistent layout, and immediate feedback during transactions, aligning with Mandel’s rules. A drawback is occasional clutter on complex pages, which could confuse users. Simplifying page layouts and emphasizing critical actions can improve clarity.

c. Smart Home Thermostat

The thermostat’s app interface maintains minimalism but sometimes lacks adequate error prevention features, such as alerts for incorrect temperature settings. Enhancing visual cues and adding confirmation prompts could reduce user errors. Moreover, offering more customizable options would increase flexibility, accommodating diverse user preferences.

3. Suggested Improvements for User-Friendly Design

a. Smartphone Touchscreen

First, increasing the size of touch targets such as icons and buttons can prevent accidental selections. Second, introducing gesture customization options would enable users to tailor interactions to their preferences, improving comfort and efficiency. These changes would adhere to Mandel’s principles by enhancing visibility, control, and flexibility.

b. Online Banking Platform

Reducing clutter on transactional pages by employing progressive disclosure techniques ensures critical information stands out. Additionally, integrating a simplified navigation menu can help users locate key features swiftly. These modifications promote transparency, ease of use, and reduce cognitive load, supporting Mandel’s rules.

c. Smart Home Thermostat

Implementing proactive error prevention, such as temperature alerts or suggestions, can improve safety and confidence. Also, providing more customization options, like scheduling preferences, would cater to varied user routines. These adjustments align with the golden rules by improving feedback and flexibility, making the interface more adaptable and forgiving.

4. Visual Documentation

While actual screenshots are not included here, labeled images would illustrate interface elements before and after modifications. For instance, enlarging buttons, adding prompts, or streamlining screens visually demonstrate the proposed improvements, supporting usability enhancements.

Conclusion

Effective interface design is vital for enhancing user experience and accessibility. Analyzing common daily interfaces through Mandel’s five golden rules reveals strengths and areas for improvement. By implementing targeted adjustments—such as increasing control, simplifying layouts, and adding error prevention—developers can create more intuitive, responsive, and satisfying experiences. Ongoing evaluation and refinement grounded in these principles are essential for advancing human-computer interaction in our increasingly digital world.
