This demonstration presents a gaze following system for facilitating the experiments with a contact lens. An animatronic eye model that can follow the user’s gaze in real-time was developed. The hardware and software design are introduced in this work. This system can assist the development of electronic contact lens by providing an intermedia for noninvasively conducting the experiment before the product is safe for human experiments. The self-developed contact lens can be worn on the eye model instead of an animal/human eye. The eye model can perform the same eye movement as the user in real-time without any physical contact. This allowed to indirectly collect experimental human data and to evaluate the performance of the contact lens, which is helpful to reduce time and cost of contact lens experiment.
