“…The experts' assessments outline a tool scenario that is characterized by blended toolboxes with an increasing share of electronic change management tools. This trend gets more momentum when new hybrid tools such as augmented reality [24,25] will be applied in the training of interpersonal and not only technical skills. Unlike virtual reality (e.g.…”

Being able to navigate accurately is one of the fundamental capabilities of a mobile robot to effectively execute a variety of tasks including docking, transportation, and manipulation. As real-world environments often contain changing or ambiguous areas, existing features can be insufficient for mobile robots to establish a robust navigation behavior. A popular approach to overcome this problem and to achieve accurate localization is to use artificial landmarks. In this paper, we consider the problem of optimally placing such artificial landmarks for mobile robots that repeatedly have to carry out certain navigation tasks. Our method aims at finding the minimum number of landmarks for which a bound on the maximum deviation of the robot from its desired trajectory can be guaranteed with high confidence. The proposed approach incrementally places landmarks utilizing linearized versions of the system dynamics of the robot, thus allowing for an efficient computation of the deviation guarantee. We evaluate our approach in extensive experiments carried out both in simulation and with real robots. The experiments demonstrate that our method outperforms other approaches and is suitable for long-term operation of mobile robots.

“…With AR interfaces, users can contextualize digital information in the physical world [12], leveraging real-world physics, as well as their bodily and environmental awareness in the interactions. Moreover, for multiple users, AR enables them to view a hybrid space from their own perspective, while leveraging their verbal and nonverbal cues for face-to-face or remote collaboration [11,41]. Games are one of the biggest domains that AR interfaces have been applied to.…”

The game industry and related research communities have shown a surge of interest in reality-based interfaces that create "embodied" game play experiences. Handheld AR (HAR) is a reality-based interface that renders digital objects onto a player's perception of the physical world. HAR creates a hybrid space in which players can leverage their existing physical and social skills to interact with the game system and with each other. Although HAR has received some attention in the world of handheld gaming, there is little research that summarizes and communicates design principles and implications across multiple examples. In this paper, we analyze and generate design lessons from dozens of HAR games, drawn from academic and commercial AR games, and also our years of experience designing and teaching HAR game design. We summarize our experience in this new field into a set of design "pre-patterns" as a means of formalizing significant design lessons derived from these existing practices into repeatable principles and solutions. We contribute to both the game and interaction design communities with pre-patterns that support embodied game play. KEYWORDS:Handheld augmented reality interface, design patterns, game design, game interface. As new designers and researchers approach HAR technology, they are asking themselves similar questions. What kind of experience can HAR support and create for the player, aside from the shear "novelty" of the interface? What are the constraints and complexities that this technology adds? How can we transform embodied interaction with a HAR interface into meaningful embodied game play? Both AR research and game design communities have something to contribute to the discussion. AR researchers have investigated the affordances and constraints of AR interfaces [11,12], and empirically examined AR systems in a number of contexts, including collaborative work, instructor support, learning, and games [7,[13][14][15][16][17][18]. Game designers are familiar with game elements and conventions that are critical for enjoyable game experiences. We hope to bridge this discussion between the two communities by presenting our results as a collection of design pre-patterns for HAR games. INDEX TERMS:Design pattern research is a tool to capture and communicate repeated solutions for recurring problems in the field [19][20][21]. Although it was first created in the context of the mature field of architecture, recent research has suggested the idea that sharing design knowledge might also be appropriate for less mature design domains, such as ubiquitous computing and home technology [22,23]. Recognizing that HAR game design is a nascent, fast-growing domain, we adopt the term "pre-patterns" in our work, which has been used to identify patterns that focus on summarizing ongoing practice to inspire new design.In this paper, we present nine design pre-patterns that leverage four kinds of embodied human skills [4]. Different from software engineering design patterns, where the "problems" are usually ...

Abstract: Blending reality and virtuality, these interfaces let users see each other, along with virtual objects, allowing communication behaviors much more like face-to-face than like screen-based collaboration.
