Human–Machine Interaction

Frequency-encoded eye tracking smart contact lens for human–machine interaction


Eye tracking techniques enable high-efficient, natural, and effortless human-machine interaction by detecting users’ eye movements and decoding their attention and intentions. Here, a miniature, imperceptible, and biocompatible smart contact lens is proposed for in situ eye tracking and wireless eye-machine interaction.

Employing the frequency encoding strategy, the chip-free and battery-free lens successes in detecting eye movement and closure. Using a time-sequential eye tracking algorithm, the lens has a great angular accuracy of <0.5°, which is even less than the vision range of central fovea. Multiple eye-machine interaction applications, such as eye-drawing, Gluttonous Snake game, web interaction, pan-tilt-zoom camera control, and robot vehicle control, are demonstrated on the eye movement model and in vivo rabbit.

Furthermore, comprehensive biocompatibility tests are implemented, demonstrating low cytotoxicity and low eye irritation. Thus, the contact lens is expected to enrich approaches of eye tracking techniques and promote the development of human-machine interaction technology.

Design and characterization of the eye-tracking SCL


Demonstrates the wide application potential of the proposed eye tracking SCL. By detecting the gazing direction, the SCL can calculate the real-time gazing point on the virtual screen, enabling the interaction with software, such as giving a like when appreciating Vincent van Gogh’s famous artwork The Starry Night. Robots also can be eye-controlled through the user-defined eye command input and execute multiple missions like vehicle movement and camera rotation.

With miniaturization and portability, the eye tracking system can be used in daily life and bring negligible burden to the user. 4 RF tags, integrated at the peripheral region of SCL, provided the backscattering signal for eye motion detection. The coil-shaped RF tags had different resonant frequency due to well-designed distinct structural parameters based on the mechanism of resistance-inductance-capacitance (RLC) resonator. The return loss (S11) curve, measured by a vector network analyzer (VNA) through a reading coil, provided insights into the response of the tags through wireless detection. The recognition of eye movement and closure was enabled by it. The equivalent impedance at the terminals of the reading coil is as follow.

    Genetics role in ovarian cancer

    The Medical Minute: Genetics play big role in ovarian cancer In 2024, about 19,680 women in the United States will receive a new diagnosis of ovarian cancer and 12,740 women will die from the disease, said Dr. Shaina Bruce , a gynecologic oncologist at Penn State Cancer Institute . The median age of all patients who develop ovarian cancer is 63. Historically, women at increased risk for ovarian cancer are recommended to have their fallopian tubes and ovaries removed when they have completed having children. Taking that step to protect themselves comes at a heavy price ― surgical menopause. But Bruce said medical science is catching up with ovarian cancer. Studies could lead to new methods for preventative care and the surgery needed to lower risk may be easier than it once was. Below, during Gynecologic Cancer Awareness Month, Bruce discusses the disease and why acting to reduce your risk is worth it. What’s the connection between heredity and ovarian cancer? About 25% of all cases of ...

    Multifactorial Genetic Conditions

    Multifactorial Genetic Conditions Multifactorial genetic conditions are disorders caused by the combined effects of multiple genes and environmental factors , rather than a single gene mutation . These conditions do not follow classic Mendelian inheritance patterns and instead result from complex gene–environment interactions . Factors such as lifestyle, nutrition, infections, stress, and exposure to toxins can significantly influence disease onset and severity in genetically susceptible individuals. Common examples include diabetes, cardiovascular diseases , neural tube defects, asthma, and many neuropsychiatric disorders. Understanding multifactorial inheritance is essential for risk prediction, preventive medicine, and personalized healthcare strategies. Multifactorial inheritance, polygenic traits, gene–environment interaction, complex diseases, genetic susceptibility, environmental risk factors, non-Mendelian inheritance, disease predisposition, polygenic risk score, precision ...

    X chromosome

    Gene on the X chromosome may help explain high multiple sclerosis rates in women Brain inflammation may be fueled by a gene on the X chromosome, a new study in mice suggests. And in female mice, who carry two X chromosomes, a diabetes drug called metformin may work to counteract that inflammation. If these findings bear out in later studies, they could help to unravel the long-standing mystery of why women, who have two copies of this inflammation-driving gene, are more prone to certain autoimmune diseases, particularly after menopause. A disparity between the sexes Our bodies are patrolled by immune cells that provide protection against bacteria and viruses, but sometimes, these defenses turn on us. In the autoimmune disorder multiple sclerosis (MS), for instance, the immune system attacks myelin, the fatty insulation surrounding the nerve fibers in the brain and spinal cord. This leads to symptoms such as muscle weakness and difficulty walking, as well issues with memory and thinking...
