Many educational haptic feedback devices use kinesthetic force feedback devices such as the Novint Falcon and the Phantom Omni. Although these devices are relatively cheap compared to other high end haptic feedback devices, they are still expensive for educational purposes. Our team has therefore decided to develop an affordable vibrotactile hapti

c device that can be used as an education tool for augmenting teaching of various disciplines through the use of haptics. The device must be generic enough such that it can be used in many different educational situations. Our team`s intention to use vibrotactile feedback is motivated by the fact that vibrotactile feedback devices had been used in real-world applications such as medical catheter teleoperator, gaming controller, and mobile phones with considerable success. In addition, vibrotactile feedback devices are generally less complex and cheaper compared to kinesthetic feedback devices, which makes it suitable for use in the education field. Many haptics applications have been designed for teaching scientific concepts in the educational field. For example, [1] and [2] use the Phantom Omni haptic device together with detailed molecular simulation in order to convey chemical bonding information to the user. Similarly, [3] has used the Novint Falcon to allow user to the feel the molecules and their atomic interaction forces. [4] has used haptics to teach mathematical functions to people with vision disabilities, by allowing them to feel the curve and shape of the mathematical functions. Many of the above educational haptics applications rely on commercial products such as the Novint Falcon and the Phantom Omni, Though this product are cheap compared to other high end haptic devices, they still cost from $300 for the...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
