Combining multi-touch input and device movement for 3D manipulations in mobile augmented reality environments

Asier Marzo, Benoît Bossavit, Martin Hachet
2014 Proceedings of the 2nd ACM symposium on Spatial user interaction - SUI '14  
The objective of a manipulation technique is to define how the input data modify the properties of the virtual objects. Current devices have multi-touch screens that can serve as input.  ...  To interact with these environments it is necessary to use a manipulation technique.  ...  For instance, with small screens, it is difficult to use more than two fingers simultaneously.  ...

Effects of Key Size and Spacing on the Completion Time and Accuracy of Input Tasks on Soft Keypads Using Trackball and Touch Input

Martin Schedlbauer
2007 Proceedings of the Human Factors and Ergonomics Society Annual Meeting  
A key size of 15mm appears to be sufficiently large to provide acceptable accuracy for touch input, although a key size of 10mm was equally acceptable for trackball input.  ...  This paper describes an experiment in which the performance and accuracy of data input on soft keyboards with square key of two different widths (10 and 15mm) and two inter-key gap distances (1.5 and 4.5mm  ...  Two differently sized square keys were tested (width = 10 and 15mm) at two gap distances (1.5 and 4.5mm). All 4 blocks were repeated with finger, stylus, and trackball input while standing up.  ...

Back-of-device interaction allows creating very small touch devices

Patrick Baudisch, Gerry Chu
2009 Proceedings of the 27th international conference on Human factors in computing systems - CHI 09  
The opposite is true, however, because the user's fingers occlude contents and prevent precision. We argue that the key to touch-enabling very small devices is to use touch on the device backside.  ...  In this paper, we explore how to add pointing input capabilities to very small screen devices.  ...  Using this device, we ran a user study comparing back-ofdevice touch input with front-side touch input augmented with the shift technique [23] ).  ...
