Danado J., Paterṇ F. Puzzle: a mobile application development environment using a jigsaw metaphor. In: Journal of Visual Languages and Computing, vol. 25 (4) pp. 297 - 315. Elsevier, 2014. [Online First 29 March 2014]
Objective: Create a visual mobile end user development framework, named Puzzle, which allows end users without IT background to create, modify and execute applications, and provides support for interaction with smart things, phone functions and web services. Methods: Design of an intuitive visual metaphor and associated interaction techniques for supporting end user development in mobile devices with iterative empirical validation. Results: Our results show that the jigsaw is an intuitive metaphor for development in a mobile environment and our interaction techniques required a limited cognitive effort to use and learn the framework. Integration of different modalities and usage of smart things was relevant for users. Conclusion: Puzzle has addressed the main objective. The framework further contributes to the research on mobile end user development in order to create an incentive for users to go beyond consuming content and applications to start creating their own applications. Practice: Usage of a mobile end user development environment has the potential to create a shift from the conventional few-to-many distribution model of software to a many-to-many distribution model. Users will be able to create applications that fit their requirements and share their achievements with peers. Implications: This study has indicated that the Puzzle visual environment has the potential to enable users to easily create applications and stimulate exploration of innovative scenarios through smartphones.
