Tacit Research Paper
Tacit or, in a more formal name, “Hand Mounted Haptic Feedback Sonar Obstacle Avoidance Assistive Device,” is a product made especially for the blind or for people who have vision problems. It calculates the distance to objects in front of them and translates that into pressure on the wrist. It’s wrist mounted and senses things from about 1 inch (2 cm) to 10 feet (3.5m). This device has generally fast response time (fractions of a second) to quickly navigate complex surroundings. It is designed to facilitate a vision impaired person to get around complex environments. Installed to the back of the hand, the force feedback means it does not interfere with other assistive devices that install elsewhere and use audio feedback cues. The learning curve is measured in seconds, everyone who has worn it has figured it out immediately.
Moreover, choosing the types of waves to use can be troublesome because each wave has its pros and cons. However, Ultrasonic wave is the most suitable method because it is good in just about any environment, and - more importantly - they are not as expensive as lasers despite the fact that are much larger and harder to focus compared to other waves namely Infrared and …show more content…
One of them is practicality. Placing the product on the back of the hand is more practical in many ways. Unlike the first version which was a headband, the headband had ultrasonic sensors which is great and all, but there are two major problems. First of all, the most degrees object are not at head level. Furniture and most of other things that can be easily tripped over and stubbed on are waist level or lower. Second of all, having vibrator motor constantly vibrating around head can be quite disturbing. Therefore, installing the device on the hand is the most effective way to mount it because the wearer can easily point it at anything they’re curious about and won’t be interfered by most clothes and other
