Anticipated, Momentary, Episodic, Remembered: the many facets of User eXperience

Abstract

Abstract-User experience (UX) has been defined in several ways. In general terms, it refers to everything that is individually encountered, perceived, or lived through. The literature on UX reports studies mostly focused on specific interaction events, which may have an impact on the user's emotions and feelings. This paper provides a reflection on how UX evolves over time. We performed a medium term study comparing four types of UX: Anticipated, Momentary, Episodic and Remembered (or Cumulative) experience [1]. Anticipated UX refers to the period of time before first use, and focuses on the expectations a person has on the product, service or system. Momentary UX refers to any perceived change during the interaction in the very moment it occurs. Episodic UX is an appraisal of a specific usage episode extrapolated from a wider interaction event. Remembered UX is the memory the user has after having used the system for a while. The different facets of UX have been analysed in a medium term research spanning over four weeks. The study compared the experience of ten users of a pedometer/fitness app that counts steps and burned calories all day long. The results show that the experience of use changed over time decreasing significantly before, during and after the interaction. The evaluative judgment related to the overall satisfaction with the product, was largely formed on the basis of an initial high expectation on pragmatic aspects (i.e. utility and usability) before and during the first encounters. After four weeks of use, the problems related to usability, reliability of data, and battery drain became a dominant aspect of how good the product was perceived. Hedonic qualities and Attractiveness were negatively impacted as well. The continuous reflection on the use, documented in online diaries, made the problematic aspects prevailing on the overall UX in particular on the evaluation of Episodic and Remembered UX. This prevented any change in behaviour in the participants.

An Empirical Study on User Experience Evaluation and Identification of Critical UX Issues

“…Previous UX studies have predominantly focused on short-term measurements, emphasizing experiential qualities related to improvements of product's first impression, such as usability and usefulness [11,17,22], while in recent years, an increasing number of researchers have started to emphasize the great importance of long-term user experience evaluation. Studies find that hedonic qualities like pleasure and beauty play an essential role in long-term use [23].…”

“…Hedonic quality refers to the psychological needs of the user. The AttrakDiff further divides hedonic quality into two subdimensions: stimulation and identification, which refer to the product's potential to provide positive emotional experience and ownership separately [22]. Hassenzahl indicates that hedonic and pragmatic qualities are independent of one another, but both contribute equally to the rating of attractiveness [42].…”

Readiness for Voice Technology in Patients With Cardiovascular Diseases: Cross-Sectional Study

“…Anticipated experience refers to the expectations a person has prior to the use of a solution, while momentary experience is associated with a perception after the first interaction. As a continuum, episodic and remembered experience mirror users' approaches toward the specific usage of a service and their general impressions after a longer period of use, respectively [25]. It is important to apply a systematic methodology while exploring patients' needs.…”

Experiência do usuário em AVA: uma observação da experiência de uso e não uso

“…Para isso, é interessante fazer uso de instrumentos de coletas de informações além da entrevista e observação de dados quantitativos. Experiências relatadas como de Marti (2016) revelam o uso de diários para registros da experiência momentânea bem como o uso de questionário para sondar as expectativas iniciais e posteriormente, para confirmar tais expectativas ao final da experiência.…”
