With multi-sensory stimulation and crowd-scale telepathy testing, True ESP creates an immersive experience that synchronizes the brain waves of users who are located around the world – enabling them to tap into a collective consciousness and push the boundaries of what was thought to be possible. Recent studies have demonstrated that binaural music and haptic stimulation at specific frequencies can induce neural entrainment throughout the brain – facilitating the interaction of users in real-time as they transmit and receive mental images with each other. Imagine touching a cello as it resonates, or hearing the echoes of waves crashing against rocky cliffs. Multi-sensory stimuli such as these have a powerful effect on brain waves, and can significantly strengthen our perceptual abilities. Before each testing round, binaural music and vibrotactile stimulation are used to synchronize the brain waves of all users. The iPhone's haptic engine can generate richly-textured resonance patterns, and True ESP utilizes acoustic algorithms to stimulate fingertip neurons with extraordinary detail. During each four minute telepathy test, users are divided into two equal groups of senders and receivers – with senders trying to mentally transmit an image – while receivers attempt to imagine what the other group is visualizing. Receivers select two images from a set of 9 cards – after which the groups switch roles, and then repeat the process again for a total of 3 rounds during each real-time telepathy challenge. A new test is conducted every 10 minutes around-the-clock, and users can participate as often as they want. From real-time test scores to live leaderboards, users can view the results of their telepathy challenges using interactive tools that keep them both informed and engaged. These detailed performance metrics enable users to track their progress, identify areas for improvement, and refine their ESP skills. Users can also compare their performance to that of other participants, gaining a better understanding of their relative strengths and weaknesses. True ESP presents telepathy scores as odds-to-one against chance, providing an intuitive and meaningful way to convey test results – as it allows users to easily understand the probability of correct answers, and appreciate the magnitude of their performance relative to chance. To help you develop and refine your telepathic abilities, True ESP features an interactive practice mode. A neural network and machine learning algorithms simulate the behavior of virtual participants, allowing you to sharpen your skills in a controlled environment that does not affect your cumulative ESP score. Featuring the same multi-sensory stimulation and interactive features as the live crowd test, the practice mode delivers an on-demand experience that you can use anytime. Invite your friends and family to participate in the Global Telepathy Study. True ESP was developed with infinitely-scalable architecture and deployed on high-performance servers in redundant data centers. This robust system enables the simultaneous testing of an unlimited number of users located anywhere in the world. Invite others to join you for an unforgettable experience.
