Human Factor - Mathematically Quantify User Experience
Unified Three Pillars for Product Design
A core requirement for product development is to closely link product design, objective measurement result and user experience.
- User experience: Quantitative definition of user experience, usually with establishing a mathematical model of visual perception.
- Product design: Directly apply user experience metrics to hardware design.
- Objective testing: Test results are highly consistent with user experience and hardware design.
Eye Tracking Specification and Human Factor
Eye Tracking is an engineering necessity for satisfactory user experiences in XR systems. These include fovea rendering, dynamically correcting distortion to minimize motion sickness, dynamically correcting color and brightness across the field of view to mitigate the display artifacts. Each feature has a different requirement on the eye tracking performance based on clear quantification of adequate user experiences.
Guardian Glow offers a software product to define and demonstrate these experiences mathematically and experientially, and rigorously derive quantitate yet practical specifications for eye tracking.
