It is already an extremely relevant and valuable activity in many industries and revealed as an essential element of experience design. Service prototyping is a new prominent progressive process used within service innovation intended to improve the service experience and quality while accelerating the service development process. Different types of service prototypes can be used to encompass all the different service elements throughout the service design and engineering processes. This paper presents a comparative study between the conventional and immersive service prototyping This comparison encompasses application, advantages and disadvantages of these different service prototyping. Several use cases of immersive service prototyping, either based on Virtual, Augmented or Mixed Reality technologies, are presented. This study aims to improve the body of knowledge on the use of immersive service prototyping. This is intended to help service designer understand what can be done with immersive service prototyping, and increase awareness on service prototyping. The main objective is to provide a guidance to service designers for selecting the most appropriate immersive service prototyping techniques per each case specificity.

We report in this paper about the first part of our research study on service prototyping that led to design a specific framework, model and instrument to be evaluated during several experiments. Service prototyping offers an early service experience enabling stakeholders to explore a new service idea, communicate a new service concept, and evaluate a new service design, even before the service exists. This paper presents the outcome of the literature review and the resulting designed research framework, model and instrument. The main goal is to increase and clarify the knowledge on service prototyping and to introduce the service prototyping framework and model for further validation and exploration through a series of experiments.

Immersive technologies, such as: Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), in service prototyping have the potential to enhancing the co-creation of service ideas. It is intended to transform intangible service aspects into an experience, even before the service exists. However, there is a lack of research studies comparing different forms of service prototype. Such studies would help to find out the most appropriate Service Prototype (SP) form for exploring, communicating and evaluating new service ideas. Several SP experiment sessions were conducted in France and Germany within an academic context in 2018 to compare different performance factors of conventional Service Prototypes (CSP) versus Immersive Service Prototypes (ISP). The participants have to disassemble and then reassemble a simple three-part mechanical element with the aid of four different SP forms. This paper presents the results of the experiment sessions, involving 38 participants, conducted at Furtwangen University campus in Germany. These results reveal that participants preferred ISP forms rather than CSP forms. However, it also confirms that there are still some difficulties in applying and using VR or AR devices.
