In this paper we present a novel method of hybridizing physical board games by adding dynamic and digitally controlled fields utilizing electrochromic inks. In particular we built electrochromic displays that fit the hexagon fields on the Settlers of Catan board game and thereby added the ability to change a fields resources during game play. In this paper we report on the prototypical implementation and two preliminary studies that indicate how these dynamic fields can increase the excitement and reward of playing the game.

Abstract-Due to the availability of sattelite-and radio-based location systems in most new devices, it is possible to use geographical location of a node for network management and communication protocol optimization. It is a common belief that usage of location information can bring performance benefits. However, inaccuracy and delay in obtaining such information, together with an associated overhead, can have a negative impact. In this paper we have considered a particular case of usage of location information, namely for cluster selection in mobile networks and have analyzed the impact of inaccurate movement prediction and inaccurate location estimation on its performance. The proposed algorithm is compared with two reference algorithms: when a considered node associates with either the first discovered cluster or the nearest cluster. Evaluation shows significant performance benefits in terms of average connectivity time to a cluster head and reduced overhead in case of exact future trajectory prediction. Under more realistic scenarios where location estimation or movement prediction are not perfect, performance benefits are reduced. This emphasizes the need for good movement prediction module if location-based schemes should be implemented in products.
