Dynamics of tilt-based browsing on mobile devices

Abstract

A tilt-controlled photo browsing method for small mobile devices is presented. The implementation uses continuous inputs from an accelerometer, and a multimodal (visual, audio and vibrotactile) display coupled with the states of this model. The model is based on a simple physical model, with its characteristics shaped to enhance usability. We show how the dynamics of the physical model can be shaped to make the handling qualities of the mobile device fit the browsing task. We implemented the proposed algorithm on Samsung MITs PDA with tri-axis accelerometer and a vibrotactile motor. The experiment used seven novice users browsing from 100 photos. We compare a tilt-based interaction method with a buttonbased browser and an iPod wheel. We discuss the usability performance and contrast this with subjective experience from the users. The iPod wheel has significantly poorer performance than button pushing or tilt interaction, despite its commercial popularity.

IntelliTilt: An Enhanced Tilt Interaction Technique for Mobile Map-Based Applications

“…Research into the use of tilt interaction has since been extended to a range of domains including menu navigation, text entry, mobile museum guides, photo browsing and interacting with mobile map-based applications [3,4,11]. Most existing research has focused on the use of tilt as a means of performing panning, where the tilt angles along the x and y axes are mapped onto panning speeds in the horizontal and vertical directions.…”

“…Previous research has shown that users prefer to only use one hand when interacting with maps on mobile phones [2]. Keypad interaction limits the user's freedom of movement and provides little control over panning speed [3,4].…”

“…Tilt interaction offers an intuitive alternative, with the user being able to interact with mobile map-based applications using natural gestures [3]. Tilt interaction typically allows users to interact with the display using rotations about the x and y axes.…”

Glaze: A Visualization Framework for Mobile Devices

“…Other sensors are more focused on user interaction. For example, the sensing of pose to control the orientation of graphical displays (Hinckley et al, 2005), motion as input to dynamic simulations (Cho et al, 2007) and camera input to perform cursor-like navigation and selection (Rohs, 2005).…”

Multi-context photo browsing on mobile devices based on tilt dynamics

“…In this paper, we propose a tilt-based photo browsing system with enhanced controllability from a tilt dynamics model [21] and a multi-context screen dynamics model. The dynamics model is designed for remedying major controllability errors in browsing photos.…”
