Eye Movement Tracking on iOS: Chances and Challenges

As iOS continues to grow in popularity, developers and researchers interested in human-computer interaction might wonder if there are built-in APIs for tracking user eye movements. This article explores the current state of eye movement tracking APIs on iOS, the limitations, and the potential implications for privacy.

Current State of Eye Movement Tracking on iOS

According to my knowledge, iOS does not have a native API for eye movement tracking. Apple, as a company that prioritizes user privacy, has been historically cautious about introducing features that could infringe on personal privacy. Currently, there are no public APIs available for eye movement tracking.

Third-Party APIs and Limitations

Even if third-party APIs existed, they would likely have significant limitations. Including:

These APIs would only be available within the apps that the developers have implemented them. There would be minimal cross-app interoperability. This means that tracking eye movements would be confined to a single app and information would not be accessible across multiple platforms easily. Eye movement tracking would not have all-encompassing, OS-wide availability. Therefore, if a user is using another app that does not implement eye movement tracking, there would be no way to track their eye movements.

Privacy Concerns and Apple's Stance

Eye movement tracking can definitely raise privacy concerns. Apple, in particular, is known for its strong stance on user privacy. Implementing such a feature would require extremely transparent communication with users about what data is being collected and how it is being used. Even with transparent communication, it is uncertain whether Apple would approve such an implementation. The company has a history of being wary of features that could compromise user privacy.

Screen Recording Requirement

In addition to privacy concerns, there is a vague memory of a requirement from Apple for running camera apps. According to this memory, users must display what is being captured on the screen. While this may be a safeguard to prevent unauthorized data collection, the exact policy is subject to change and more research is needed to confirm this claim.

Conclusion

While the concept of eye movement tracking on iOS is intriguing, the current landscape suggests that it remains a challenge. Developers and researchers would need to be aware of the limitations and privacy concerns before attempting to implement such a feature. Given Apple's strict privacy policies, it is unlikely that a widespread, OS-wide eye movement tracking API will be introduced in the near future.
