The PWC-iPhone transceiver also includes a playback audio codec to convert the wirelessly received digital audio samples to analog sound signals, which are then applied to the microphone input of the iPhone 3. The secondary input modalities that can be selected and customized based on individuals' existing abilities include but not limited to the vocal commands generated from users' continuous and discrete speech, the acceleration and rotation resulted from the voluntary head movements, and the diaphragm or oral controlled air pressure applied by the user by sipping and puffing through a straw. The MCU extracts the audio samples from the back telemetry packet and sends them to the playback DAC of the audio codec through I2S interface to generate analog audio signals that are audible to the users if they attach an earphone to the designated audio jack on the mTDS headset. Moreover, both the foregoing summary and following detailed description are exemplary and explanatory and are intended to provide further explanation of the presently disclosed subject matter as claimed. The system of claim 11 , wherein the speech or acoustic sensor comprises a microphone.

A block diagram of an exemplary wireless headset and control unit, such as headset and control unit of FIG. The 12 V PWC power supply is mainly used to power the analog part of tszti DAC and the relays, while the rest of the interface circuits are powered by the 3.
Overall, using the mTDS resulted in the best performance in all aspects of the task. The control unit can also have a wireless transceiver unit that is connected to or included in an UMPC or a smartphone such as iPhone, Blackberry, Android, or Windows phones. In one embodiment, the system is an assistive technology in a single, highly integrated, multimodal, multifunctional, multipurpose, minimally invasive, unobtrusive, wearable, easy to use, low cost, and reliable AT that can potentially provide people with severe disabilities with flexible and effective computer access and environmental control in various conditions.
In additional embodiments, the one or more taztk sensors comprise a respiratory or pneumatic pressure sensor. Fazti threshold is defined as the minimum sensor output taztk the magnetic tracer is held from the sensor at 1 cm distance.
Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment, and wherein:.
The system of claim 1wherein the first type of communication is proportional and the one or second types of communications are discrete. A customized head position and orientation tracking algorithm has been developed and implemented in both PC and iPhone platforms. The PWC-iPhone transceiver also includes a playback audio codec to convert the wirelessly received digital audio samples to analog sound signals, which are then applied to the microphone input of the iPhone 3.
For example, it is a quite common that individuals with high level SCI use sip-n-puff to drive their wheelchairs, head pointer to control the mouse cursor, speech recognition software to type, and a mouth stick to control their phones and home appliances.
Lack of selection function, such as mouse clicks, in head tracking devices can be compensated by using tongue or vocal commands along with head tracking. By combining two or more of the above input modalities in one highly compact, wearable, and wireless device, the mTDs can provide its end users with a unique experience, in which they can not only enjoy the benefits of each modality by itself, as mentioned above, but also have access to a combination of a subset of all of these modalities at the same time without any assistance from a caregiver while switching from one modality to another.
Unfortunately, none of the existing ATs can effectively and safely address both applications alone.
tazti 1.1.2 (XP)
In the multimodal mode, both the mTDS and Dragon were active, and the subject was required to use the tongue commands TDS for mouse navigation and clicks, and verbal commands Dragon for typing.
Switching between different modes is controlled by specific commands sent from the computer. Once a complete audio frame 54 tazhi has been acquired in 6. For example, pressure data from a pressure sensor can be received at sensor interfaceprocessed by the MCU and transmitted to an outside device using wireless transceiver and antenna Another group of ATs, based on eye movement tracking have been successful for computer access.
A method and apparatus for quantitatively evaluating mental states based on brain wave signal processing system. In some embodiments, the TDS is a small permanent magnetic tracer is attached to the tongue using tissue adhesives, clipping, piercing, or tongue implantation. Removing the tongue implantation may, however, be more involved and require a small surgery.
The other end of the string is knotted to the mTDS headset.

Therefore, the pressure sensor is also sampled at 50 Hz. Due to taazti time critical nature of streaming audio, the audio data transfers within the MCU, i. Considering the PWC supply voltage might be slightly tzzti among the chairs from different vendors The system of claim 12wherein the speech or acoustic sensor further comprises an earphone.
However, unlike a traditional Bluetooth mouse which receives the movement information from an optical sensor, the Bluetooth module in the mTDS transceiver will directly receive this information from the iPhone after it processes the magnetic sensor signal.
In some embodiments, an advantage of the present invention is that a single, compact, easy-to-use, easy-to-maintain, wireless, wearable, and relatively low cost system can provide its end users with multiple control solutions, all of which are simultaneously accessible to them, to interact with computers and other devices in their environment for multiple purposes. The method of claim 17wherein the sensing unit further comprises a tqzti transceiver unit for wirelessly transmitting and receiving data.
In some further embodiments, the first type of communication is discrete and the second type of communication is proportional.
In addition, mTDS increases the number of alternatives available to users to accomplish a task, thus gives users the ability to switch among different input modalities, based on their convenience, familiarity, and environmental conditions. After being properly calibrated, the three components X, Y and Z of the magnetometer can be used to measure the local earth magnetic field, which strength and direction with respect to the North Pole is known if the geographical position and latitude is determined.
The system of claim 9wherein the inertial measurement unit comprises at least one of a 3-axial magnetometer, a 3-axial accelerometer or a 3-axial gyroscope.
