“…A limitation of this study, and of any touch-based interaction study (e.g., Hwangbo, Yoon, Jin, Han, & Ji (2013); Romano, Paolino, Tortora, & Vitiello (2014) ;Tu, Ren, Tian, & Wang (2014)), is that the results depend on the specific devices that are used. Results may not be generalizable to devices with difference specifications (e.g., different screen, processor speed, or native gestures).…”

This study aimed to determine the most appropriate touch-based interaction technique for I2Vote, an image-based audience response system for radiology education, in which users need to accurately mark a target on a medical image. Four plausible techniques were identified: landon, take-off, zoom-pointing and shift. The techniques were implemented in such a way that they could be used on any modern device. An empirical study was performed in which users marked a target on an image using all four techniques on either a smartphone or a tablet. The techniques were compared in terms of accuracy, efficiency, ease-of-use, intuitiveness, and compatibility Downloaded by [Fudan University] at 16:30 16 May 2015A c c e p t e d M a n u s c r i p t 2 with the different devices. The results showed that shift was the most accurate technique, but it was hampered by its high complexity and low intuitiveness. Land-on was the fastest technique, but also the least accurate. Take-off and zoom-pointing provided the best trade-off between accuracy, efficiency, ease-of-use, and intuitiveness. We therefore conclude that both take-off and zoom-pointing are viable interaction techniques for I2Vote.

“…There are studies about the influence of font size in users' performance and preference when they are using mobile devices, both with Western characters (Darroch, Goodman, Brewster, & Gray, 2005) and Chinese characters (Huang, Rau, & Liu, 2009), as well as the influence in readability of texts (Mustonen, Olkkonen, & Hakkinen, 2004) and text entry performance (Lin, 2015;Romano, Paolino, Tortora, & Vitiello, 2014;Tu & Ren, 2013) when using this kind of device. There are also studies about the adequate font size for older people to improve their performance and reading speed when they are using mobile devices (Bernard, Liao, & Mills, 2001;Darroch, et al, 2005).…”

Mobile devices have small screens that require that the user constantly resizes the web content in order to read the text. This study sets out to: (1) check whether current mobile devices are able to zoom or increase the font size of text on websites and (2) check the most efficient, effective and satisfying usability method for the user to do so. A preparation stage with mobile devices and an experiment with real users were designed and carried out. Results suggested that current mobile devices are able to resize text in web pages. User testing returned that there is no difference in the ability to perform the task, nor in errors or time to complete it between text resizing methods. However, users preferred increasing/decreasing font size links method in nontouch screen devices. In the light of results, we recommend to provide links to resize the text in web contents and make them readily available.

Figure 1: TapStr is an unambiguous reduced-Qwerty that maps the standard Qwerty in a single row divided into four zones. Tapping on a zone enters the central character and stroking on a zone towards one of the eight characters around the border enters the respective character. Dwelling for 500 ms upon a tap or stroke enters the uppercase letters or the secondary characters, distinguished using a smaller font (right). Dwelling for 1000 ms activates or deactivates Caps Lock. Stroking towards '↙' switches the layout for numeric and special characters (right) and stroking towards ' ' switches the layout for emojis.
