Sammanfattning
Voice assistants are increasing in popularity with the rise of devices like smart speakers
and screens. As people grow accustomed to using these assistants, it is likely they
would want use the same voice assistant in their car. Many modern cars already
support integration of voice assistants from both Apple and Google. In this project,
voice assistants integrated into the vehicle and their effects on safety in terms of
increased diverted attention and cognitive load are examined. Current voice assistants
are also reviewed. Apple Siri and Google Assistants, two commercial voice
assistants, are evaluated under the conditions of manual driver, as well as with
longitudinal and lateral assistive drive features. New, improved design solutions
and guidelines were evaluated through two prototypes with different approaches to
solving found problems in existing voice assistants. The results indicate several
similarities and differences in the existing design guidelines for the different voice
assistants. Users provide input and thoughts about the existing solutions. New design
solutions for decreasing distraction and cognitive load are presented. These new
solutions can help continued research and further improvement of voice assistants
within cars in the future to come.
