With the increasing prevalence of smartphones, gesture-based interaction has arrived in our everyday life, but we still do not exploit its full potential. This paper describes the benefits and drawbacks of gestural input and presents interaction techniques that address these drawbacks.
Gestures provide the user with a new form of interaction that mirrors their experience in the real world. They feel natural and require neither interruption nor an additional device. Furthermore, they do not limit the user to a single point of input, but instead offer various forms of interaction.
However, gestures also raise issues that are not relevant with traditional methods of input. The need to be learned and remembered, which requires the development of guides that promote the discoverability and memorability of these gestures and deal with input and recognition errors. Another aspect is the design of the gestures itself, which should make them memorable and easy and comfortable to execute.

Zusammenfassung der Kapitel (Chapter Summaries)
1. Introduction: This chapter introduces the increasing prevalence of gesture-based interaction, particularly with the rise of smartphones, and sets the stage for exploring the advantages and drawbacks of this interaction method. It highlights the naturalness of gesture interaction as it mirrors real-world communication, contrasting it with the limitations of traditional desktop computing paradigms.
2. Advantages: This chapter delves into the benefits of gesture-based interaction. It emphasizes the immediate and powerful nature of gestures, eliminating the need for interruptions and additional devices. The inherent intuitiveness and enjoyment associated with gestures are also highlighted, referencing studies that demonstrate improved user experience and performance compared to traditional input methods. Examples are given to show how gestures allow for multiple points of input and the definition of several parameters simultaneously.
3. Drawbacks and possible solutions: This section addresses the challenges posed by gesture-based interfaces. It identifies issues such as discoverability, memorability, fatigue, and recognition errors. It then proposes and discusses various solutions designed to alleviate these drawbacks. The chapter covers systems like OctoPocus, ShadowGuides, and GestureBar, detailing their mechanisms for enhancing discoverability and providing feedback to the user.
