Summary
Background
Many individuals will experience a voice disorder in their lifetime, especially occupational
voice users. While a number of voice monitoring systems have been developed, most
were designed with the clinician/researcher as the end user. For a patient to use
these systems, they need field experts to help them interpret data from the system
to understand its meaning. Most of these systems would have challenges in being used
in a preventative context with the occupational voice user as the sole system user.
Objective
The current study introduces a novel design approach: user-centered design (UCD) with
paper prototypes in the creation of a voice monitoring system for voice disorder prevention
(VDP). The goal of this design approach is to design systems that are engaging and
intuitive for users so they will be interested in interacting with the system and
be able to benefit from the system without the need of external support.
Methods
The current study was conducted in two phases: an iterative design phase and a test
phase. In the iterative design phase, 15 participants gave their opinions on the measures
and feedback designs they felt would be the most beneficial to users. In the test
phase, the researchers collected real voice data over multiple sessions for 18 additional
participants and provided this data using the final feedback displays from the design
phase.
Results
By engaging in UCD, the researchers identified key design challenges for VDP: (1)
educating the user, (2) balancing contextualization and granularity, and (3) addressing
disconnection between user and system goals.
Conclusion
UCD holds promise for designing VDP systems that are both engaging and intuitive for
occupational voice users.
