Hack your senses Mart Objartel 2010
Hack your senses • Tongue vision • EM fields sensing • Sense of compass
A Sixth Sense for a Wired World “What if, seconds before your laptop began stalling, you could feel the hard drive spin up under the load? Or you could tell if an electrical cord was live before you touched it? For the few people who have rare earth magnets implanted in their fingers, these are among the reported effects -- a finger that feels electromagnetic fields along with the normal sense of touch.”
A Sixth Sense for a Wired World(2) • the magnet works by moving very slightly, or with a noticeable oscillation, in response to EM fields. • This stimulates the somatosensory receptors in the fingertip, the same nerves that are responsible for perceiving pressure, temperature and pain. • locate electric stovetops and motors, and pick out live electrical cables • Appliance cords in the United States give off a 60-Hz field. "It is a light, rapid buzz"
A Sixth Sense for a Wired World(3) • Carried out by enthusiasts, not medical practitioners • MRI? • Risk of infection • Long-term problems • Corrosion
Tongue vision • Real-time images on tongue
Tongue vision (2) • Perception with electrical stimulation of the tongue is better than with fingertip electrotactile stimulation, and the tongue requires 3% (5-15 V) of the voltage. The mean current for tongue subjects was 1.612 mA. • The goal is to develop a practical, cosmetically acceptable, wireless system for blind persons, with a miniature TV camera, microelectronics and FM transmitter built into a pair of glasses, and the electrotactile array in a dental orthodontic retainer.
Tongue vision (3) • Not just in the lab - http://vision.wicab.com/technology/ • BrainPort Vision technology
Tongue vision (5) • ~3cm x 3cm tongue display, presented at approximately 30 frames per second, yielding an information rich image stream. Our research suggests that the tongue is capable of resolving much higher resolution information and we are currently working to develop the optimal tongue display hardware and software. Original 100 points 625 points 3600 points
Tongue vision (5)FAQ • How long does it take to learn? • 2-10h • Will I experience vision similar to what I once had? • Experience is as resembling a low-res vision • Can it hurt me? • Intensity is adjustable, impulses feel like champagne bubbles
Compass belt • belt lined with 13 vibrating pads • power supply and a sensor that detected Earth's magnetic field • Whichever buzzer was pointing north would go off. Constantly.
Compass belt (2) • perception of the vibratorsdisappear whilst conscious information processing is displaced by a new „sense of direction“ • "I suddenly realized that my perception had shifted. I had some kind of internal map of the city in my head. I could always find my way home. Eventually, I felt I couldn't get lost, even in a completely new place."
Compass belt (3)- tactile stimulators • Applications? • and almost a quarter of crashes at night , resulted from spatial disorientation. • Tell the pilot planes orientation, up & down.
