Eye tracking technology measures eye movement and gaze point. This technology is employed across various fields, from academic research and clinical diagnostics to user experience testing and marketing studies. Determining the total investment required for an eye tracking system is complex because the cost is highly variable. The final price depends significantly on the intended application, the type of hardware used, and the required level of data precision.
Pricing by Hardware Category
The initial capital investment is best understood by categorizing the hardware. Remote, screen-based trackers are often the most accessible entry point, with basic consumer-grade models starting in the range of $100 to $1,000. These devices typically attach below a monitor and are sufficient for general user experience testing or introductory academic projects. Professional-grade remote systems, often used for more rigorous desktop research, fall into a mid-range bracket, costing between $2,000 and $10,000.
High-end binocular setups can reach up to $15,498. Mobile or wearable eye tracking glasses represent a higher investment due to the complexity of miniaturizing the optics and integrating the necessary processing power. While some low-end or do-it-yourself (DIY) wearable systems can be built for under $1,000, professional, research-grade eye tracking glasses generally start around $5,000 and can exceed $20,000.
The highest cost bracket is reserved for specialized or integrated systems. These systems include setups for use within magnetic resonance imaging (fMRI) scanners or high-fidelity simulation cockpits. They typically exceed $10,000 and often fall into the $25,000+ range. These prices reflect the engineering required to operate accurately within constrained or complex settings.
Factors Determining Price Variation
The wide price variation within each hardware category is justified by specific technical specifications. The sampling rate, measured in Hertz (Hz), is a major cost driver, as it dictates how many times per second the system records the eye position. Low-cost systems generally operate at 60 Hz, which is the minimum standard for capturing basic fixations, while mid-tier systems often use 250 Hz.
High-end research systems, which are significantly more expensive, can achieve sampling rates between 1,000 Hz and 2,000 Hz. This higher frequency is necessary to accurately analyze rapid, microscopic eye movements, such as saccades, which are crucial for cognitive research. Another key factor is accuracy and precision, which is measured in degrees of visual angle. Basic systems may have a precision of 0.5° to 1°, while top-tier laboratory devices boast precision as fine as 0.01° to 0.1°.
The system’s robustness to head movement and its calibration requirements also impact the price. More expensive systems can maintain data integrity even if the user moves their head freely, minimizing data loss. Advanced wearable glasses, for example, often use artificial intelligence to compensate for natural head movements, ensuring a stable gaze map in real-world environments. The field of view, along with the system’s ability to quickly re-acquire the gaze after a blink or look-away, adds to the complexity and cost of the hardware.
Ongoing and Auxiliary Costs
The purchase price of the hardware is only one part of the total cost of ownership. Software licensing is a primary auxiliary cost, often separated into a perpetual license fee or a subscription-as-a-service (SaaS) model. While some basic software for personal use might be a one-time purchase or a small monthly fee, professional analysis platforms are typically sold as annual subscriptions for individual modules, which can range from approximately $3,250 to $3,600 per module.
These software packages are required to process the raw coordinate data into meaningful visualizations like heatmaps and gaze plots. Maintenance and support contracts represent another significant ongoing fee, often charged annually to cover technical assistance, hardware repair, and software updates. An extended warranty or support contract can cost around 10% of the original hardware list price per year.
Integrating the eye tracking system into specialized or existing research platforms often requires additional customization costs. This may necessitate professional consulting or bespoke development work. Training personnel to properly use the complex hardware and interpret the resulting data is an expense that can be factored into the overall budget.
