Abstract Do you want to know what an anti-chiece Latin square is? Or a non-consecutive toroidal modular We invented ton of new types squares, some inspired by existing Sudoku variations. can’t wait introduce them and answer important questions, such as: do they even exist? If so, under conditions? What are their interesting properties? And how we generate them?

This paper describes a toolkit for measuring fun with children aged between 5 and 10. The relationship of fun to usability is discussed and three dimensions of fun; Endurability, Engagement, and Expectations are described. A set of tools that can be used in empirical studies to measure these dimensions of fun is described in detail. These tools include a Smileyometer, a Fun-Sorter and an AgainA...

Relations between OWFs, PRGs and PRFs (revised) Jan-Erik Ekberg February 19, 2002 1 Introdu tion These le ture notes intend to give an overview of the provable relations between one-way fun tions (OWFs), pseudorandom generators (PRGs) and pseudorandom fun tions (PRFs). Only a sele ted number of proofs and redu tions are thoroughly presented in this paper (most are left to the referen es), but t...

Recent work has emphasized the importance of pure delay components as well as rate components in the user perceived performance of elastic Internet applications, namely Web browsing. “Fun factors” have been previously introduced to describe the obtained performance with respect to the maximum possible performance on a scale of zero (no fun) to one (maximum fun). In this paper, several options f...

This paper describes an empirical study of fun, usability, and learning in educational software. Twenty Wve children aged 7 and 8 from an English primary school participated.
