The Blinking Cursor: An Overlooked Accessibility Barrier in Software Development
For most software developers, the blinking cursor in code editors and Integrated Development Environments (IDEs) is an expected, even unnoticed, part of their daily workflow. Yet, for individuals with sensory processing disorders, visual sensitivities, and other neurodivergent conditions, the inability to disable this constant flicker presents a significant barrier to accessibility.
The Problem with the Blinking Cursor
The blinking cursor has been a staple of text-based interfaces for decades, intended to signal where text input will appear. However, this seemingly minor design choice can be highly disruptive for some users.
- Sensory Overload: People with sensory processing differences, such as those with autism or misophonia, can find the flickering motion distracting or even distressing. Constantly shifting visual elements can create cognitive fatigue and impede focus.
- Photosensitive Conditions: Some individuals with epilepsy, migraines, or other neurological conditions may be triggered by repetitive flashing patterns, no matter how subtle.
- Attention and Processing Differences: Developers with ADHD or other attention-related conditions may struggle with maintaining focus when an element of their screen is repeatedly drawing their eye.
- Lack of Customization: While many accessibility-conscious applications allow for font size changes, dark mode, and other user-friendly options, most coding environments do not offer a way to disable or adjust the blink rate of the cursor.
Ableist Design in Software Development
The exclusion of an option to disable the blinking cursor is a prime example of ableist design—when technology is built primarily for neurotypical or able-bodied users, disregarding those with different needs. The lack of awareness in mainstream development environments is reflective of the broader issue of ableism in tech, as discussed in the article Agile Development: Ableist Extroverts Setting Agendas (Tameri).
Agile development, for example, often favors fast-paced, highly collaborative processes that do not accommodate neurodivergent thought patterns, sensory needs, or working styles. The unwillingness to implement small but meaningful accessibility options, such as disabling the blinking cursor, reveals a deeper bias: the assumption that all developers work in the same way and have the same needs.
A Call for Change
It is time for software development tools to incorporate better accessibility options, including:
- Cursor Blink Rate Settings: Users should be able to reduce the blink rate or disable the blinking cursor entirely.
- Alternative Visual Indicators: Highlighting the cursor location with a static color change or outline could be an effective alternative.
- Accessibility-First Development: IDE creators and text editor developers should actively seek input from neurodivergent and disabled users when designing features.
Several operating systems allow for some control over cursor blink rates, but IDEs and text editors like VS Code and Sublime Text have yet to offer built-in options for users who find the blinking cursor problematic. Until these features are standard, developers needing an accessible workspace are left with clunky workarounds, such as modifying system settings (where possible) or using third-party extensions—if they even exist for their preferred editor.
IF YOU HAVE A SENSORY DISORDER, AND WANT NO BLINKING CURSOR, PYCHARM IS AMAZING!
Conclusion
The lack of control over the blinking cursor in most development environments is a small yet significant oversight that highlights broader issues of ableist design in software. By incorporating accessibility-conscious choices, developers and tool designers can ensure that coding environments are truly inclusive for all. Until then, many neurodivergent and disabled developers will continue to struggle with an unnecessary and avoidable barrier to productivity.
