A Framework for Mouse Emulation that Uses a Minimally Invasive Tongue Palate Control Device utilizing Resistopalatography

The ability to interface fluently with a robust Human Input Device is a major challenge facing patients with severe levels of disability. This paper describes a new method of computer interaction utilizing Force Sensitive Resistor Array Technology, embedded into an Intra-Oral device (Resistopalatography), to emulate a USB Human Interface Device using standard Drivers. The system is based around the patient using their tongue to manipulate these sensors in order to give a position and force measurement; these can then be analyzed to generate the necessary metrics to control a mouse for computer input

Aboriginal Culturation of the Environment in South Australia and excerpts from the novel The Glass Harpoon

The colony of South Australia was unique among the colonies that were set up in Australia in the eighteenth and nineteenth centuries in that it was established by an English company with significant capital and a unique plan for colonisation which would attract both capitalists and workers and which would attempt to replicate the class structure of England (Pope, p.6). There were no convicts or transport ships, but free settlers, many seeking religious freedom, many with a hunger for land, many furthering the fortunes of large families in England

Investigation into Wheelchair Mobility Control that Uses a Minimally Invasive Intra-Oral Palate Control Device utilising Resistopalatography Techniques

Interfacing with conventional wheelchair input devices is a major challenge when it comes to patients with high levels of disability. This paper intends to report on the new method of wheelchair mobility interfacing using Resistopalatog- raphy. The technique proposed here is based around utilising the tongue as the controlling muscle group to input desired movement into a force sensitive sensing dental retainer. Using the position of the force, and force applied a direction and speed metric can be calculated emulating conventional joystick output data. The resistopalatography technique has been applied to other Human Machine Interfacing areas with success [1]

Passive wireless tags for tongue controlled assistive technology interfaces

Tongue control with low profile, passive mouth tags is demonstrated as a human–device interface by communicating values of tongue-tag separation over a wireless link. Confusion matrices are provided to demonstrate user accuracy in targeting by tongue position. Accuracy is found to increase dramatically after short training sequences with errors falling close to 1% in magnitude with zero missed targets. The rate at which users are able to learn accurate targeting with high accuracy indicates that this is an intuitive device to operate. The significance of the work is that innovative very unobtrusive, wireless tags can be used to provide intuitive human–computer interfaces based on low cost and disposable mouth mounted technology. With the development of an appropriate reading system, control of assistive devices such as computer mice or wheelchairs could be possible for tetraplegics and others who retain fine motor control capability of their tongues. The tags contain no battery and are intended to fit directly on the hard palate, detecting tongue position in the mouth with no need for tongue piercings

A Framework for a Low Power on Body Real-Time Sensor System using UHF RFID

This paper details the use of an acceleration measuring system which can transmit in real-time sensor data through UHF RFID to a computer. Existing methods of real-time transmission of sensor data rely on power-intensive Bluetooth or Wi-Fi technologies which result in devices that require large bulky batteries, this causes the overall device size to be high and thus can potentially cause issue during use. By harnessing status flags within a specific UHF RFID chip and custom reader software conforming to the EPC GEN2 standard, continuous streaming data rates of 5.2KBps were achievable. These enhanced data rates were shown to be reliable up to a range of 2.4M with above 99.99% data integrity. The power consumption of this methodology was found to be below 2mW during full power continuous transmission. In summary this paper outlines and lays the foundation for the use of UHF RFID to deliver sub-2mW low latency, high reliability streaming methods within the domain of on body transmission

Powered Wheelchair Platform for Assistive Technology Development

Literature shows that numerous wheelchair platforms, of various complexities, have been developed and evaluated for Assistive Technology purposes. However there has been little consideration to providing researchers with an embedded system which is fully compatible, and communicates seamlessly with current manufacturer's wheelchair systems. We present our powered wheelchair platform which allows researchers to mount various inertial and environment sensors, and run guidance and navigation algorithms which can modify the human desired joystick trajectory, so as to assist users with negotiating obstacles, and moving from room to room. We are also able to directly access other currently manufactured human input devices and integrate new and novel input devices into the powered wheelchair platform for clinical and research assessment

Charged Dilaton Black Holes with Unusual Asymptotics

We present a new class of black hole solutions in Einstein-Maxwell-dilaton gravity in $n \ge 4$ dimensions. These solutions have regular horizons and a singularity only at the origin. Their asymptotic behavior is neither asymptotically flat nor (anti-) de Sitter. Similar solutions exist for certain Liouville-type potentials for the dilaton.Comment: 24 pages, harvmac.tex, no figure
