  Context: Research on human aspects within the field of software engineering
(SE) has been steadily gaining prominence in recent years. These human aspects
have a significant impact on SE due to the inherently interactive and
collaborative nature of the discipline.
  Objective: In this paper, we present a systematic literature review (SLR) on
human aspects affecting developer-user interactions. The objective of this SLR
is to plot the current landscape of primary studies by examining the human
aspects that influence developer-user interactions, their implications,
interrelationships, and how existing studies address these implications.
  Method: We conducted this SLR following the guidelines proposed by Kitchenham
et al. We performed a comprehensive search in six digital databases, and an
exhaustive backward and forward snowballing process. We selected 46 primary
studies for data extraction.
  Results: We identified various human aspects affecting developer-user
interactions in SE, assessed their interrelationships, identified their
positive impacts and mitigation strategies for negative effects. We present
specific recommendations derived from the identified research gaps.
  Conclusion: Our findings suggest the importance of leveraging positive
effects and addressing negative effects in developer-user interactions through
the implementation of effective mitigation strategies. These insights may
benefit software practitioners for effective user interactions, and the
recommendations proposed by this SLR may aid the research community in further
human aspects related studies.
