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.

Design Example

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...

Area of Science:

Biomedical Engineering
Human-Computer Interaction
Assistive Technology

Background:

Developing intuitive and unobtrusive human-device interfaces is crucial for assistive technology.
Existing interfaces often require significant training or invasive components.

Purpose of the Study:

To demonstrate a novel human-device interface utilizing tongue position with low-profile, passive mouth tags.
To evaluate user accuracy and learning rates with this tongue-controlled system.

Main Methods:

Passive, wireless mouth tags were developed to detect tongue-tag separation.
User accuracy was assessed using confusion matrices for tongue position targeting.
Training sequences were implemented to measure learning rates and performance improvements.

Main Results:

High user accuracy was achieved, with errors close to 1% after short training.
Zero missed targets were recorded, indicating reliable performance.
The intuitive nature of the interface was evidenced by rapid learning rates.

Conclusions:

Low-profile, passive wireless mouth tags offer an intuitive and effective human-device interface.
This technology has significant potential for controlling assistive devices for individuals with motor impairments.
The cost-effective and disposable nature of the mouth-mounted technology enhances its practical applicability.
