Abstract: Well-being/quality of life has emerged as a strand of inquiry in human factors research that has expanded
the field’s reach to matters beyond fit, functionality and usability. This effort has been spearheaded by
“hedonomics,” a human factors conceptualization of well-being that reflects the philosophical notion of
hedonia, traditionally defined as pleasure. However, recent work in the psychology of well-being has shown
that hedonia constitutes only one facet of well-being. In light of this, the concept of “eudaimonics” as a
complement to hedonomics is introduced. First, these concepts are positioned relative to their counterparts
in philosophy: where hedonomics is characterized by pleasure and avoidance of pain (hedonia),
eudaimonics is characterized by flourishing and personal excellence (eudaimonia). Following this, a
working conceptual framework for eudaimonics that is informed by the psychological literature is
presented. An expansion of the hedonomics model of design priority hierarchy is offered. Applications to
the domains of ageing well and technologies for older populations are proposed. Directions for future work,
including the adoption and modification of psychology instruments for human factors research, is discussed.
1 INTRODUCTION
Human factors/ergonomics (HF/E; hereafter “human
factors”), a multidisciplinary domain of research and
practice that looks at the fit between people and
systems, is typically concerned with three main
issues: safety, productivity, and prevention of error
(Meister 1999; Vicente 2004). However, a growing
number of researchers and practitioners have begun
to consider other factors that affect fit, including
satisfaction and motivation for life activities and the
impact those activities have on overall well-being.
A relatively new domain of inquiry called
“hedonomics,” which takes its name from the Greek
root of “hedonia,” has attempted to tackle the
intersection of well-being, people and systems.
Hedonomics is explicitly concerned with positive
and pleasurable interactions between people and
systems (Hancock et al., 2005; Helander and Tham,
2003). However, a review of the philosophical
foundations and recent work on psychological
constructs of well-being show that hedonomics is
limited by its focus. This combined with recent
insights on the need for a well-rounded perspective
of well-being, e.g. for older adults and mobility
(Nordbakke and Schwanen, 2014), argue for an
expanded view of well-being in human factors that
addresses well-being factors that are conceptually
outside the purview of hedonomics.
In this paper, “eudaimonics” is introduced as a
complementary concept to hedonomics and potential
area of research and practice that is (a) proposed by
the philosophical underpinnings of well-being, and
(b) supported by established psychological work on
well-being. A preliminary conceptual framework for
eudaimonics as well as an expansion of the
hedonomics model of design priority is proposed.
The main contribution of this paper is therefore an
informed expansion of well-being in human factors
from philosophical and psychological perspectives,
particularly with respect to the ageing process.
2 CONCEPTUAL OVERVIEW
In the last century, interest in well-being has taken
root within many disciplines, including health,
gerontology, philosophy, and psychology. A wealth
of terms and definitions abounds within and among
these domains. In psychology, for instance, well-

being has been defined as (a) “optimal psychological
experience and functioning” (Deci and Ryan, 2008,
p.1), (b) happiness, positive affect, and lack of
negative affect (Bradburn, 1969), and (c) life
satisfaction (Ryff, 1989), among many others. To
compare with a perspective from another domain:
the World Health Organization defines well-being as
“individuals’ perception of their position in life in
the context of the culture and value systems in which
they live and in relation to their goals, expectations,
standards and concerns” (World Health
Organization, 1997, p.1). Likewise, the constructs
that make up conceptualizations of well-being and
the measures used to assess well-being are equally
varied.
This diversity of domains and definitions provide
several valid options on which to base a conceptual
understanding of well-being in human factors. Given
the ties human factors has to psychology and the
effort undertaken by psychologists to achieve a
coherent, rich, measurable conceptualization of well-
being, as well as overlap between the psychological
literature and conceptualizations of hedonomics, we
have chosen to focus on the psychological literature.
2.1 Philosophical Foundations
Well-being can be traced to Hellenic philosophy on
what constitutes “the good life” (Ryan and Deci,
2001; Keyes et al., 2002; Ryff, 1989).
Disagreements among philosophers gave rise to two
perspectives on well-being: the Aristippian
“hedonia” as the pursuit of pleasure; and the
Aristotelian “eudaimonia” as the pursuit of
excellence (Deci anf Ryan, 2008; Ryan and Deci,
2001). Recently, an alternative to the Aristippian
view has been proposed: “hedonic utility,” a view
based on the utilitarian philosophy of 18
th
century
philosopher Jeremy Bentham (Sirgy, 2012; Graham,
2012, p.33). Regardless, the essence of each position
is that eudaimonia focuses on virtue and hedonia
focuses on pleasure.
2.2 Psychological Foundations
As in the time of the early Greek philosophers,
debate about what well-being is—how it should be
defined, what it constitutes, how it can be measured,
and what to call it—continues. A perusal through the
literature will reveal several terms that are
sometimes used to refer to the same or different
constructs. For example, in his recent text on the
psychology of well-being, Sirgy (2012) argues for
three constructs of well-being: “hedonic well-being”
(which constitutes happiness and affect, components
that others, have attributed to subjective well-being),
“life satisfaction” (which others consider to be a
component of subjective well-being, or SWB), and
“eudaimonia” (which encompasses psychological
well-being, or PWB, and flourishing), while also
sometimes using “subjective well-being” to refer to
all aspects of well-being. In contrast, Waterman et
al., (2010) argue that “hedonic well-being” can be
used to refer to SWB, where both refer to the same
concept. Here, we will review the literature and
endeavour towards a consensus in terminology and
concepts using the latest empirical research on how
well-being constructs can be distinguished.
2.2.1 Subjective Well-being and Hedonia
Subjective well-being (SWB) has a lengthy history
within psychology. It is important to note that while
some (e.g. Sirgy) may use the term to refer to well-
being as a whole from a psychological perspective,
and it can be confused as a reference to subjective
approaches to assessing well-being, SWB is a
standalone concept with empirical backing.
Historically, SWB has been defined as an
individual’s subjective level of happiness, comprised
of and measured through three components: positive
affect, a lack of negative affect, and life satisfaction
(Diener et al., 1999; Diener, 1984). Notably,
researchers in this area commonly use the term
“happiness” to refer to SWB (Deci and Ryan, 2008).
A new view of SWB has been developing within
the past two decades: Kahneman, Diener and
Schwartz’s (1999) conceptualization of SWB as a
hedonic construct. In this view, SWB as “happiness”
is analogous to presence of pleasure and absence of
suffering. However, a hedonic view of SWB creates
a problem for the inclusion of life satisfaction as a
component of well-being, because life satisfaction
involves conscious appraisal of one’s position in
life, a process that falls under the purview of
eudaimonia (Deci and Ryan, 2008). In sections 2.2.3
and 2.2.4, we discuss how this problem may be
resolved through a unified model of well-being
based on recent empirical work.
2.2.2 Psychological Well-being and
Eudaimonia
Research on psychological well-being (PWB) has
only gained stead in the last two decades (Deci and
Ryan, 2008). It is important to note that the term
does not merely refer to well-being from a
psychological perspective, and could instead be
better understood as “cognitive” well-being, where
knowledge of one’s well-being requires cognition:
self-awareness and conscious thought processes
about the self and one’s impact on the self and the
world. Additionally, PWB (as a psychological
construct) has been earlier and more explicitly tied
to eudaimonia (as its philosophical foundation) in
the literature than SWB to hedonia; further, some
have argued that PWB and eudaimonia should not
be conflated. We will attempt to reconcile these
differing outlooks while working towards a unified
view of this aspect of well-being.
Waterman (1993) introduced the notion of
eudaimonia as an essential quality of well-being.
Drawing from early philosophy, Waterman proposed
that eudaimonia is self-realization: a process of
fulfilment characterized by personal expressiveness
(PE) as one moves closer to one’s true self, or
“daimon.” A truly eudaimonic process meets six
criteria: deep understanding, unusually good fit with
the activity, feeling alive, feeling fulfilled, feeling
that the activity is “meant to be done,” and feeling
that one is truly being oneself (Waterman, 1990).
Waterman makes explicit ties to intrinsic motivation
(Deci, 1971), flow theory (Csikszentmihalyi, 1991),
and self-actualization (Maslow, 1962).
Ryff (1989) introduced the concept of
psychological well-being (PWB) as a multi-
dimensional construct distinct from SWB. She
developed and then validated with colleagues (Ryff
and Keyes, 1995) six dimensions of PWB:
autonomy (personal will to action), environmental
mastery, personal growth, positive relations with
others, purpose in life, and self-acceptance. More
recently, Ryff and Singer (2008) performed a close
reading of Aristotle’s eudaimonia (from
Nichomachean Ethics) and discussed how it relates
(and does not) to PWB. Even so, there is some
contention among scholars, particularly Waterman
(2008), regarding the validity of using PWB alone to
characterize eudaimonia.
In their review, Deci and Ryan (2008) posit two
central differences between Ryff and Waterman’s
conceptions of eudaimonic well-being (EWB): one,
that Ryff’s PWB is about an individual’s global
well-being, whereas Waterman’s PE is specific to an
activity; and two, that Ryff’s PWB is content-
specific, e.g. the environment, relationships, etc.,
whereas Waterman’s PE is content-free.
More recently, Ryan and Deci (2001) have
argued that their self-determination theory (SDT)
underpins and gives rise to eudaimonia. SDT (Ryan
and Deci, 2000) comprises three basic psychological
needs: autonomy (also an aspect of Ryff’s PWB),
relatedness (again, an aspect of Ryff’s PWB), and
competence. They posit a number of differences
between SDT and PWB. For instance, SDT nurtures
EWB while PWB describes it. Further, SDT is
thought to nurture both SWB and EWB.
2.2.3 Life Satisfaction
Recent large sample studies that employed factor
analysis have shown that hedonia and eudaimonia
are related but distinct concepts (Proctor et al., 2014;
Huta and Ryan, 2010). However, the results of these
studies also suggest that life satisfaction, generally
considered a component of SWB (Linley et al.,
2009), is a distinct concept that may be determined
or mediated by hedonic and eudaimonic well-being
together. This provides some empirical support for
the notion that SWB cannot be considered entirely
hedonic; however, whether this is due to the
cognition involved in assessing one’s own life
satisfaction or some other reasons(s) is unknown.
2.2.4 Synthesis
The above overview presents an emerging picture of
how psychological conceptualizations of well-being
and philosophical standpoints on well-being can
mesh. Psychological research involving large sample
studies using factor analysis have shown that SWB
and PWB are distinct but related concepts (Linley et
al., 2009; Keyes et al., 2002). From a philosophical
standpoint, researchers tend to align SWB with
hedonia and PWB with eudaimonia (Waterman et
al., 2010), although some contention remains (Deci
and Ryan, 2008; Ryan and Deci, 2001) and
conceptual relatedness, if not overlap, almost
certainly exists. In any case, a growing area of
empirical work points to the need for a well-rounded
view of well-being that incorporates hedonic and
eudaimonic qualities (Huta, 2013; Nordbakke and
Schwanen, 2014).
A working model that synthesizes our conceptual
overview can be found in Figure 1. We use this
model to express a conceptual understanding of
hedonomics that is based on relevant, established
philosophical and psychological concepts, and
further propose a complementary domain that we are
calling “eudaimonics.”
2.3 Hedonomics
Hedonomics as an area of research and practice was
first proposed by Helander and Tham (2003) in light
of increasing interest within human factors on the
topic of affect, and in particular pleasure, as opposed
to pain, which has generally been associated with the
established topic of safety. Helander and Tham
make reference to Kahneman’s work on hedonic
well-being as a founding theory, while also drawing
on several relevant trajectories within human factors,
namely: Kansei (feeling) engineering (Nagamachi,
1995), affective computing (Picard, 1995),
pleasurable product design (Jordan, 1998), and
Donald Norman’s insights on pleasure in design
(Norman, 2002), which has recently culminated into
a new area called positive computing (Calvo and
Peters, 2014). However, perhaps because of the
nature of the paper as an editorial, the authors do not
suggest a particular theory or provide a theoretical
framework for the concept of hedonomics; rather,
they offer it as a new area of research and practice.
Figure 1: Conceptual overview of well-being.
Hancock (who coined the term “hedonomics”
and is cited by Helander and Tham as the inspiration
for bringing attention to this topic), Pepe and
Murphy (2005) offer a deeper take on the theory and
conceptual foundations of hedonomics. Here, the
focus of hedonomics is explicitly positioned
opposite to ergonomics: where ergonomics focuses
on the prevention or alleviation of pain, hedonomics
focuses on providing or increasing pleasure. Hence,
“additive” (rather than subtractive) human factors.
Further, hedonomics is contrasted with human-
centred design, which the authors argue takes a
general stance to design (e.g. designing for the
capacities of people in general, or centaurs in
general, to use their example), rather than focusing
on an individual and their personal needs. Thus,
human-centred design must be extended to include
“individuation,” or individual-centred design.
2.3.1 Theoretical Model
The structure of the hedonomics model is based on
Maslow’s (1970) hierarchy of needs, where lower-
level needs must be met before high-level needs can
be achieved. In the hedonomics model, the first three
needs are the domain of traditional human factors:
safety, functionality, and usability. The final two
needs are the domain of hedonomics: pleasurable
experience (hedonia) and individuation (defined by
the authors as “personal perfection”). An exception
is made for usability, which the authors consider a
cross-domain factor. In the hierarchy, the needs
closest to the bottom are more relevant to a general
(or “collective”) approach to design, while the needs
closest to the top are more relevant to an
individuation approach to design.
To the authors, pleasurable experience may be
generated by designers’ use of “hedonomic
affordances,” which attempt to elicit specific
affective states in the end-user. This idea reflects
psychological conceptualizations of SWB, which is
the domain of hedonia, thus complementing the
psychological work on well-being. Individuation
may be attained by developing smart tools that allow
end-users to customize their experience, perhaps by
responding to their affective needs.
2.3.2 Critique
A review of the model combined with a close
examination of how hedonomics is described by the
authors in-text and with respect to the psychological
literature reveals some discrepancies. As expected
given the term’s inspiration (hedonia), the authors
define hedonomics as the promotion of pleasure.
However, they also at times characterize its scope as
eudaimonic. For instance: “To fulfil the needs of the
user, we need to incorporate an explicit recognition
of motivation, quality of life, enjoyment, and
pleasure into design recommendations” (Hancock et
al., 2005, p.11). Further, they argue that the concept
of individuation, which in the model is separate from
the need for a pleasurable experience, fulfils the
need for autonomy, a eudaimonic construct. Finally,
they refer to Peterson and Seligman’s (2004) work
on the nature of virtue (philosophically the domain
of eudaimonia). This reference provides motivation
for the adoption of well-being into the domain of
human factors but also serves to highlight a gap in
the model: explicit inclusion of eudaimonic factors.
These issues raise two harmonizing possibilities
for expansion of the model: (1) clarification of the
definition and scope of hedonomics, and (2)
introduction of a eudaimonic aspect to the model. To
this end, we propose an expanded human factors
model of well-being that explicitly addresses the
concept of a eudaimonics of human factors.
3 CONCEPTUAL FRAMEWORK
The philosophical and psychological underpinnings
of well-being advocate at least two perspectives: a
hedonia of human factors—the already established
hedonomics—which is concerned with positive and
negative affect (and especially pleasure), but also a
eudaimonia of human factors—we propose
“eudaimonics”—which addresses flourishing as
personal expressiveness and self-realization. In
Figure 2, we offer an expanded version of Hancock
and colleagues’ hierarchy of hedonomic needs as a
general model of well-being in human factors that
includes a eudaimonic perspective.
Figure 2: A human factors model of well-being that
includes a eudaimonic aspect. Based on the hierarchy of
hedonomic needs by Hancock, Pepe and Murphy (2005),
which was based on Maslow’s (1970) hierarchy of needs.
Here, eudaimonics shares the need for
individuation with hedonomics (as per the idea that
individuation elicits autonomy, a eudaimonic
construct). The new need that represents the
eudaimonic aspect of well-being—flourishing—is a
catch-all term derived from the psychological
literature on eudaimonic well-being. Its position at
the top of the hierarchy is based on the philosophical
and psychological justifications of how hedonia and
eudaimonia are positioned with respect to each other
as well as the original model’s use of a scale of
global-individual appropriateness.
3.1 Application to Ageing Well
If we assume that optimal well-being is a common
goal of all adults regardless of age, then systems,
technologies, and devices must be designed with all
elements of the model in mind. When these systems
are designed to replace or augment changing human
functions, such as mobility, sensory and cognitive
functions, it is insufficient to only consider human
factors and hedonomic elements. Further, the
context in which these systems are used may have a
direct impact on an individual’s sense of self and
ability to flourish, particularly as the individual faces
new challenges due to changes in their health and
well-being status as they age. Finally, efforts are
required to determine how the design of assistive
technologies and systems can positively affect a
person’s transitioning state of well-being and sense
of self resulting from the aging process.
Going forward, measures of well-being that
include hedonic and eudaimonic factors must be
adapted or devised so that they are actionable by and
fathomable to designers and users, similar to how
usability measures (Rogers et al., 2011) have been
developed. For instance, Huta and Ryan’s (2010)
Hedonic and Eudaimonic Motives for Activities
(HEMA) instrument may be used to assess human-
system interactions for specific contexts, tasks and
activities, but this needs to be tested in human
factors work. Further, eudaimonic well-being design
guidelines similar to the safety, functionality and
usability triad that can be found in textbooks and
standards, e.g. the ISO/TC 159 Ergonomics
standard, are required. This will involve empirical
human factors studies in which eudaimonia, as well
as hedonia and other aspects of well-being (e.g. life
satisfaction), are assessed.
4 CONCLUSIONS
An initiative towards establishing well-being as an
important factor in the fit between humans and
systems is underway. To this end, we have identified
eudaimonics as a potential domain that complements
the established area of hedonomics. We have
developed a conceptual framework that distinguishes
the two and is informed by relevant philosophical
and psychosocial concepts. We have discussed how
this framework may be used to understand the
ageing process and the affect on ageing people. We
can suggest several trajectories for future work:
Adapting existing, validated psychological
instruments for use in human factors research.
Development of design guidelines for
eudaimonic systems.
Validation and expansion of the model: While
founded on sound theoretical work that has
empirical backing in psychology, the model
needs to be validated with respect to human
factors knowledge.
