Wireless Control of Smartphones with Tongue Motion Using Tongue Drive Assistive Technology

Conceptual
Tongue Drive System (TDS) is a noninvasive, remote and wearable assistive innovation that people groups with serious handicaps control their surroundings utilizing their tongue movement. TDS makes an interpretation of particular tongue motions to charges by identifying a little perpetual attractive tracer on the clients' tongue. We have connected the TDS to a cell phone (iPhone/iPod Touch) with a redid remote module, added to the iPhone. We likewise relocated and ran the TDS sensor flag preparing calculation and graphical UI on the iPhone progressively. 

Tongue Drive Assistive Technology

The TDS-iPhone interface was assessed by four capable subjects for dialing 10-digit telephone numbers utilizing the standard phone keypad and three strategies for provoking the numbers: visual, sound-related, and psychological. Preparatory outcomes demonstrated that the interface worked dependably at a rate of 15.4 digits for every moment, all things considered, with unimportant mistakes.


Presentation
People with extreme in capacities accordingly of causes extending from spinal rope wounds (SCI) to amyotrophic horizontal sclerosis (ALS) require assistive advancements (AT) regularly to gain more noteworthy autonomy. Among different ATs, those giving option control to PC get to and wheelchairs are the most imperative for now's way of life since they can enhance clients' personal satisfaction by empowering correspondence and autonomous versatility.

There is a wide assortment of ATs, for example, taste and puff, eye trackers, head pointers, electromyography (EMG) switches, and voice controllers for people with extreme incapacities, which are financially accessible. In any case, each of these gadgets has impediments that render it unacceptable or perilous for both PC get to and wheelchair control in different indoor and open air situations. This is the reason people in the end wind up contingent upon and conveying at least two ATs, each for specific undertakings or situations. This will force learning and budgetary weight on the person in the first place, and additionally reliance on a parental figure for exchanging amongst ATs and altering them on a progressing premise. Once in a while people do without specific assignments or keep away from specific situations essentially in light of the fact that their AT may not be sufficiently assistive.

There are sure parts of the ATs that outcome in their pointlessness in specific situations or for specific undertakings. Some of these components rely on upon the sort of data sources that the AT requires to work. For example, eye trackers rely on upon eye movement and dependably meddle with their clients' typical visual errands. They are additionally influenced by surrounding light and can't be utilized as a part of the dim or direct daylight. Alternately voice controllers require a calm situation since they are profoundly vulnerable to outside clamor and impedance. Different elements that specifically influence the AT ease of use are measure, weight, usefulness, usability, support, cost, and even the presence of the AT.


Tongue Drive System is currently remotely connected to a cell phone (iPhone) by a little RF module that is somewhat bigger than a quarter and interfaces with its 30-stick charging port. We have likewise created firmware that deals with dependable remote correspondence between the eTDS headset and the RF module utilizing a couple of framework on-chip remote miniaturized scale controllers, and also proficient programming that handles the whole SSP calculation and the GUI continuously utilizing the iPhone's restricted preparing assets. The essentials of this TDS-cell phone interface is that it makes the TDS genuinely wearable by mitigating its clients from the weight of conveying a PC on their wheelchairs. 

Despite the fact that we have executed the present TDS interface on an Apple iPhone stage because of its prominence and capable programming environment, it is moderately straight forward to relocate to other prominent stages, for example, Windows Mobile, Google's Android, Nokia's Symbian, and significantly more intense and conservative frameworks to come. Facilitate assessment of the TDS-cell phone interface is required by potential end clients not just in the controlled research center or clinic situations additionally, all things considered, circumstances, in their homes, work environments, and outside.
