Abstract
We investigated the spatial knowledge that users of pedestrian navigation support acquire about the navigated area. In particular, we compare two conditions: A spatially richer condition, which provides continual access to information about route directions and surroundings via a local map at closest zoom level. And a spatially sparser condition, in which route directions are given via a tactile display and only as decision points come up. In a field study, 28 participants navigated on foot through a previously unfamiliar urban area. Data on resulting spatial knowledge, gaze distribution on environmental features, performance, individual spatial abilities, and user experience were collected and analysed. We were specifically interested in the route and survey knowledge that participants had acquired. The results point to advantages for acquiring route knowledge through using the sparser, tactile display condition and for acquiring survey knowledge through using the richer map condition. We conclude with discussing ramifications for the design and use of different types of pedestrian navigation support systems for different task scenarios.

Abstract
We present a novel method for deriving solution strategies used when solving rotation tasks. Process-based findings about physical rotation are obtained from an analysis of how angular disparity between stimuli changes over time. Data on angular disparity was gathered through a study on mental and physical rotation with 37 primary school students between the ages of 8 and 11. For controlling physical rotation, students used touch-based input on our iOS app Rotate it!, which also logged their interactions. Data on changes of angular disparity was used in the construction of Markov models. The models were employed to generate sets of synthetic angular disparity time courses, based on which we identified three distinct rotation-based solution strategies. Our analysis has implications for understanding processes involved in physical and mental rotation alike. It helps to lay grounds on which novel interactive diagnostic and training tools for spatial skills can be developed.

Abstract
Difficulty in TETRIS is adjusted by adapting the speed with which blocks fall. In this contribution, we describe results of an exploratory study in which we investigated relationships between players performance and their subjective assessment of difficulty and fun. We tested five different algorithms that, instead of adjusting game speed, adjust difficulty by choosing blocks based on the current game state. With our results, we establish pile height and bumpiness as parameters that indicate the performance of a player during a live game, discuss the inherent difficulty of different block choosing algorithms and show how the relationship between fun and perceived difficulty varies for distinct player groups. With regard to adapting difficulty, we argue that one can still teach an old dog such a TETRIS a lot of new tricks.
