During this phase, designers identify the main functionalities, concepts and contents of the system without creating a fully functional system. This paper aims to discuss the development of ProtoSketchAR, a tool enabling Augmented Reality (AR) prototyping by sketching. The application has different interaction modes, depending on the performed functionality. Basically, it is possible to create 2D/3D sketches to be placed in the real environment and to manipulate them.  \nThese functionalities allow the creation of virtual elements that can be used to prototype screens of AR applications. The application is web-based so that it can be run on any device with a compatible AR browser, regardless of the operating system used.  \nCCS Concepts  \n• Human-centered computing ! Mixed / augmented reality;  \n1. Introduction  \nApplications developed for Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) exploit the senses of the user to obtain a more engaging and immersive experience. Each one of these technologies has its characteristic features: in Virtual Reality, the user is wholly involved in a simulated virtual world, while in Augmented Reality he/she can define an enhanced version of the real world that is obtained through the use of digital effects, sounds or other sensory stimuli provided by the technology. Finally, Mixed Reality combines both AR and VR elements, allowing the user to directly interact with digital objects. Typically, the development of AR, VR and MR applications involves developing platforms or specific graphics engines, such as A-Frame, Unity or Unreal Engine. It is immediately clear that such tools are reserved for developers with technical skills, experience in programming or in the creation of 3D content. In addition, developing complete applications using these tools is a time-consuming and costly task and requires asignificant commitment from the developers. For this reason, it is crucial to find a way to define an initial primordial version of the project (prototype) without necessarily have the ability to use oneof the development platforms mentioned above. The prototyping phase is essential to understand the objectives and the technical aspects to implement before actually starting with the development. There are several ways of setting up this phase, and the implementation choices depend on various aspects: budget, time and materials available, designer skills, specific requests, and so on. Generally, the prototypes can have different categories: they can be low or high fidelity, in such a way as to define the level of detail and  \nfunctionality present within the prototype, or they can be vertical or horizontal, task-oriented or based on scenario [RvHPR18] .  \nIn the case of an AR, VR or MR application, it is recommended to use a type of immersive prototyping, which allows total immersion by the user in order to \"deceive\" his/her senses and perceive the immersive reality as real, while allowing natural intuitive interactions. This approach typically creates a high fidelity prototype and requires more effort than a simple paper-based sketch. Although the existence of prototyping techniques more suitable for specific application contexts, this does not prevent using an approach that involves the combination of several techniques. For example, paperbased prototyping is not entirely suitable for creating AR, VR or MR prototypes, but it can be used as a preliminary technique for immersive prototyping [RvHPR18] .  \nIn this paper, we introduce ProtoSketchAR, a web-based application that provide a tool capable of creating low-fidelity AR prototypes.
