Poster:Discovering requirements of behaviour change software systems from negative user experience

Behavior Change Software systems (BCSSs) have shown promising outcomes in terms of promoting healthy behaviors. However, a negative User Experience (UX) can be induced by BCSS if designers do not have clear understanding of the requirements that factually help in changing the user behavior that achieves a sustainability goal. In order to get insights into how to discover such sustainability requirements, we propose a discovery approach, whose emphasis is placed on negative UX assessed through attitudes and behaviors expressed by users due to the lack of fulfillment of actual user needs. The approach is tested on existing software systems designed for preventing or reducing Repetitive Strain Injury as a particular category of BCSS. Twelve requirements that contribute to social sustainability were discovered

ReFridge App Concept

ReFridge is an app with the goal of helping reduce household food waste. When a grocery receipt is scanned, the app creates an organized fridge inventory that will help decrease the amount of food that is thrown out. The user will receive custom expiration reminders and suggested recipes while using meal prepping calendars and personalized shopping lists. Buying, cooking and consuming food will become more efficient and users will experience an increase in healthy and regulated eating habits

Towards a Non-Functional Requirements Discovery Approach for Persuasive Systems

[Abstract] A number of software systems that attempt to help people achieve behavior change have been proposed in various domains such as health and wellness. However, sometimes, such systems have failed to provide a satisfactory or sustainable User Experience (UX), as it is observed when users may be reluctant to respond to the activation of the systems' changing demands. Moreover, a negative User Experience (UX) can be exposed by Behavior Change Support Systems (BCSS) if designers do not have clear understanding of the requirements that factually help changing the user behavior that accomplishes a sustainability goal. We first explored the Persuasive System Design (PSD) model that should be considered in UX assessment of BCSSs. Then, we propose a requirements discovery process that can be considered to redesign a software interactive system based on negative UX.This work has received partial support by the projects FEDER-UE CSI ED431G/01, ED43C 2018/29, accreditation 2016-2019 ED431G/08, KUSISQA supported by N° 014-2019-FONDECYT-BM-INC.INV, NOVA LINCS UID/CEC/04516/2019, MICINN IJC2018-037522-I, RTI2018-099646-B-I00Xunta de Galicia; ED431G/01Xunta de Galicia; ED43C 2018/29Xunta de Galicia; ED431G/08Gobierno de Chile; 014-2019-FONDECYTBM-INC.INVRepública Portuguesa.
