Design Example

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

The Tongue and Taste Buds

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Area of Science:

Biomedical Engineering
Rehabilitation Technology
Human-Computer Interaction

Background:

Existing tongue tracking devices often require invasive, powered sensors and trailing wires.
There is a need for non-invasive, user-friendly assistive technologies for individuals with severe motor impairments.

Purpose of the Study:

To introduce a novel passive tongue control and tracking device.
To provide a means of environmental and computer control for severely disabled and quadriplegic individuals.

Main Methods:

The device utilizes a passive haptic interface with inductive sensors.
No powered electrical sensors or intraoral components are required, eliminating trailing wires.

Main Results:

The device successfully performs keyboard and mouse functions for computer control.
It enables users to control daily electrical devices and appliances, enhancing environmental interaction.

Conclusions:

The operating principle and setup of this passive tongue Human-Computer Interface (HCI) have been validated through laboratory trials.
Further clinical trials are necessary to assess the device's efficacy in disabled populations prior to commercialization.
