This paper presents the findings of a comparative study investigating different input interfaces for a mobile phone games application. A standard mobile phone joystick interface is compared with a phone camera interface to detect the phone translation and tilt to control a ball's movement within various levels of difficulty of a virtual maze game. Game completion times together with the resultant user experience for each of the games was collected during the studies. Results indicate that the joystick control provided the fastest completion times for each game, but with the lowest levels of user engagement. The Tilt interface, although perceived as challenging by the participants, provided the greatest level of user involvement, independent of game complexity. The design of appropriate human interfaces which go beyond the standard phone keypad is suggested. The selection and design of these interfaces should also consider the intended user experience for the game.

Purpose In what is going to be an uncertain and rapidly evolving global economic landscape, it is clear that firms will have to become more adaptive and responsive to changes within their marketplace. To do this, businesses will not only need to engage in business model experimentation but also look to embrace business model innovation as a core competency and a means for sustained competitive advantage. Design/methodology/approach This paper outlines how a design process of experimenting and prototyping can apply to the design of business models through the case study of hypothetical luggage company Packright. Findings Five meta-models with differing foci are illustrated as an accessible and provoking framework that provides a new logic to classifying, experimenting and prototyping business model designs. Practical implications These five meta-models provide a tangible starting point from which a business can begin to explore different perspectives and gain insights into the internal and external capabilities of their company. Originality/value This paper builds upon the emerging research and exploration into the importance and relevance of dynamic, design-driven approaches to the creation of innovative business models.
