The design of elevator button symbols is a notable example of how some industries develop their own symbols without consulting design experts, integrating standard symbol conventions, or conducting usability testing. This oversight is widespread in modern engineering and product design, and it leads to several critical issues:
- Products with poorly designed symbols become difficult to use.
- Even products with well-designed symbols can confuse users when existing symbols are given new meanings by inexperienced designers.
- Safety can be compromised because important directives become unclear due to confusing symbols, lack of attention to design, or poor placement of controls.
The Science Behind Elevator Buttons
Elevator buttons differ from ordinary buttons, as they incorporate modern technology and advanced materials. The placement and design of these buttons are influenced by scientific research to enhance functionality. Elevator systems have evolved, and so have their buttons. What was once a simple mechanical press has now transformed into touch-sensitive panels, intuitive interfaces, and even smart technologies.
Elevator buttons have adapted to match the sophisticated elevator systems we see today. From traditional push-buttons to advanced touchscreen controls, these improvements enhance user experience and safety. Below, we dive into the science behind elevator buttons, explore the various types, and help you choose the right ones for your needs.
Five Key Problems with Elevator Button Symbols
The first and most significant issue with the door open/close symbols on elevator buttons is their lack of clarity. Many users struggle to differentiate between them. There are a few reasons for this:
- Designers often use triangular arrows, which are more commonly associated with audio/visual controls, leading to confusion.
- Studies suggest that arrow shape matters, and triangular arrows can be perceived ambiguously.
- Lack of sufficient whitespace in the design adds to the difficulty of interpreting the symbols.
Based on numerous discussions and feedback, it seems the combination of ambiguous arrow shapes and poor use of whitespace contributes to user confusion.
The Evolution of Elevator Buttons
Elevator buttons have come a long way since their inception. Initially, they were mechanical, similar to other buttons in daily life. Over time, the design and operation of these buttons improved, becoming softer, more durable, and visually appealing. Many buildings still use mechanical buttons because of their simplicity, longevity, and cost-effectiveness. Moreover, these buttons can be customized to suit specific needs, from symbol design to font choice.
However, with advancements in technology, modern elevators now feature touch-sensitive buttons and smart controls that enhance accessibility and ease of use.
Standards for Elevator Button Symbols
There are two main standards related to elevator button symbols. The ASME standard focuses primarily on safety, while the ANSI standard addresses accessibility for people with disabilities. However, finding these standards can be challenging because they are not easily accessible and are primarily concerned with functional aspects rather than the aesthetic design of symbols.
How Elevator Buttons Work
Elevator buttons function through a combination of electrical signals and mechanical components. When a button is pressed, it activates an electrical circuit that communicates with the elevator’s control system. This system directs the elevator motor to move the car either up or down. Additionally, these buttons control the opening and closing of elevator doors, ensuring smooth entry and exit for passengers. Indicators next to the buttons also light up to show which floor has been selected, helping users know the status of the elevator.
Alternative Symbols
Some designers have created alternative symbols for elevator buttons, particularly for the door open/close functions. Although these designs have not been rigorously tested or developed according to standard principles, they seem to perform better in terms of user clarity than the original symbols.
Types of Elevator Buttons
There are various types of elevator buttons available, each with its advantages and disadvantages. Understanding the options can help you select the right type for your needs. Below are some of the most common elevator buttons:
- Floor Buttons: These buttons are typically rectangular and allow passengers to select their desired floor. When pressed, they light up to confirm the selection, guiding users through the building.
- Call Buttons: Located outside the elevator, these buttons summon the elevator to the desired floor. They are often accompanied by an indicator light that shows when the button has been pressed and the elevator is on its way.
- Emergency Buttons: These are designed for passenger safety. They trigger alarms or send signals to security in case of emergencies.
Conclusion
Elevator buttons are a crucial part of the overall elevator experience. From design and usability to safety and functionality, the way these buttons are created and placed has a significant impact on their effectiveness. Choosing the right type of elevator buttons, ensuring they comply with established standards, and making sure they are easy to interpret can greatly improve the user experience.
FAQs About Elevator Button Symbols
1. Why are elevator button symbols often confusing?
Elevator button symbols, especially the open/close door buttons, are often confusing because they use triangular arrows that are typically associated with audio/visual controls. The arrow shapes can also be ambiguous, and the lack of whitespace in the design further complicates interpretation.
2. How have elevator buttons evolved over time?
Elevator buttons have evolved from simple mechanical press-buttons to more advanced touch-sensitive panels and smart technologies. Modern buttons are designed to be more intuitive, responsive, and durable, using cutting-edge materials and technology.
3. What are the most common types of elevator buttons?
The most common types of elevator buttons include:
- Floor Buttons: Used to select the desired floor inside the elevator.
- Call Buttons: Located outside the elevator to summon it to a floor.
- Emergency Buttons: Used to alert authorities in case of an emergency.
4. What standards govern elevator button symbols?
Two key standards govern elevator button symbols:
- ASME Standard: Primarily focuses on safety aspects.
- ANSI Standard: Mainly concerned with accessibility for individuals with disabilities.
5. Why is it important to follow standards for elevator button design?
Following standards ensures that elevator button symbols are easy to understand, safe to use, and accessible to everyone, including individuals with disabilities. Non-compliance with standards can result in confusion, potential safety risks, and difficulty using the elevator
