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:

Assistive Technology
Human-Computer Interaction
Sensory Impairment Research

Background:

Limited assistive technologies exist specifically for individuals with dual sensory loss (deafblindness).
Existing technologies for visual or hearing impairments are not always suitable for deafblind individuals.
Deafblindness encompasses diverse experiences, influencing technology use.

Purpose of the Study:

To envision future technologies supporting people with severe hearing and visual impairments.
To explore potential technological solutions for accessing space and astronomy experiences for the deafblind.
To identify desired characteristics for future assistive technologies.

Main Methods:

Literature review on deafblindness, museum accessibility, and social-haptic communication.
Analysis of three case studies: Kennedy Space Centre's Rocket Garden, observatory visits, and the Mars 2020 mission launch.
Imagining future technologies based on identified challenges and needs.

Main Results:

Identified challenges in accessing space and astronomy for individuals with deafblindness.
Documented adaptations of existing technologies and improvised strategies.
Proposed desired characteristics and conceptualized future technologies.

Conclusions:

Future technologies should be designed inclusively for deafblind individuals.
Social-haptic communication offers a promising avenue for augmenting sensory input.
Tailored technological solutions are crucial for equitable access to complex experiences.
