Recent estimates show over 2.8 billion smartphone users worldwide 35, with nearly twice as much time spent consuming content on mobile devices as desktop/laptop in the US (increases to 3× in India, 6× in China), and exceeding time spent watching TV 36. Further, little is known about eye movement behavior on small smartphone displays as most prior research focused on large desktop displays. There are some cheaper eye tracking solutions available for the desktop 33, 34, though not for mobile screens (state-of-the-art mobile eye trackers cost on the order of ten thousand USD). The underlying methodology, known as eye tracking, has been used for decades as a reliable way to measure eye movements 30, 31, 32.ĭespite the numerous benefits of eye tracking, research and applications have been limited by the high cost of eye trackers and their inability to scale due to the use of specialized hardware (e.g., infrared light source, multiple high spatio-temporal resolution infrared cameras). Understanding eye movements has been central to research in attention and visual processing in the brain, including focus areas such as visual search 11, 12, 13, scene perception 14, 15, 16, and reading 17, 18, to name a few.īeyond basic vision research, eye movements have also been of interest to the broader research community with applications ranging from saliency models for visual content analysis 19, design evaluation 20, usability and consumer behavior research 21, 22, 23, driving 24, gaming 25, 26, gaze-based interaction for accessibility 27 to medical research 28, 29. Thus, eye movements offer a direct way to measure overt spatial attention, and have been considered by some to provide a window into the brain and mind 9, 10. The human eye moves 3-4 times per second on average, pausing to sample information from those important scene regions 6, 7, 8. Selective attention is the mechanism by which our brain selects and focuses on a few important scene regions for cognitive and visual processing (see refs. Our results show the potential for scaling eye movement research by orders-of-magnitude to thousands of participants (with explicit consent), enabling advances in vision research, accessibility and healthcare.Īs we move through rich and complex environments in our everyday life, the retina is bombarded with vast amounts of visual information of ~10 10 bits/s 1, 2. In addition, we demonstrate the utility of smartphone-based gaze for detecting reading comprehension difficulty. Using data from over 100 opted-in users, we replicate key findings from previous eye movement research on oculomotor tasks and saliency analyses during natural image viewing. We show that the accuracy of our method is comparable to state-of-the-art mobile eye trackers that are 100x more expensive. We leverage machine learning to demonstrate accurate smartphone-based eye tracking without any additional hardware. Little is known about eye movement behavior on phones, despite their pervasiveness and large amount of time spent. However, most prior research has focused on large desktop displays using specialized eye trackers that are expensive and cannot scale. If you give an app permission, but you change your mind later, you can turn off that app’s access to your eye tracker in Settings > Privacy > Eye tracker and under Choose apps that can access your eye tracker, switch the individual settings for apps and services to On or Off.Eye tracking has been widely used for decades in vision research, language and usability. The first time an app needs to access your eye tracker, it requests your permission. How to control which apps can access your eye tracker This page describes the eye tracker settings that are available to you and how they work.
