This paper addresses modern-day, touch screen devices that use a stylus for interaction and text input. To date, such devices utilized QWERTY-based designs for virtual keyboards. However, the assumption here is that there is no necessity for implementing QWERTY-based virtual keyboard designs on modern-day devices such as personal digital assistants...

... design targeted female users, and the design was intended to represent a feminine 'look and feel' [ figure 2]. Figure 3 illustrates the vocal words (AEIOU) grouped together at the top prior screen space followed by the second level of BHNWY for the most commonly used words (e.g. H, hi, how, W, where, why, and so on). ...

... to technicalities and functionality, only 3 aesthetically pleasing virtual keyboard designs were selected for the user trial. The 3 selected alternative virtual keyboard designs are shown in Figure 3 (design 1), Figure 4 (design 2) and Figure 5 (design 3) as opposed to design 4, which is a standard QWERTY keyboard. ...

In this article, we use an entry to an international architectural student competition on future care to explore how social norms about older bodies may be challenged by designs that are sensitive to the spatial contexts within which we age. The power of the ‘My Home’ design by Witham and Wilkins derives from its hand drawn aesthetic and thus we co...

... For direct touch input, we implemented our custom T9 soft keyboard layout on the smartwatch (Figure 6d) by closely following the design guidelines for small screen display [32]. We maximized the button size, and used high contrast, bright color and legible text at a minimum of 14pt for effective viewing. ...
We introduce FingerT9, leveraging the action of thumb-to-finger touching on the finger segments, to support same-side-hand (SSH) text entry on smartwatches. This is achieved by mapping a T9 keyboard layout to the finger segments. Our solution avoids the problems of fat finger and screen occlusion, and enables text entry using the same-side hand which wears the watch. In the pilot study, we determined the layout mapping preferred by the users. We conducted an experiment to compare the text-entry performances of FingerT9, the tilt-based SSH input, and the direct-touch non-SSH input. The results showed that the participants performed significantly faster and more accurately with FingerT9 than the tilt-based method. There was no significant difference between FingerT9 and direct-touch methods in terms of efficiency and error rate. We then conducted the second experiment to study the learning curve on SSH text entry methods: FingerT9 and the tilt-based input. FingerT9 gave significantly better long-term improvement. In addition, eyes-free text entry (i.e., looking at the screen output but not the keyboard layout mapped on the finger segments) was made possible once the participants were familiar with the keyboard layout.
... However, text entry using touch-sensitive screens such as handheld devices is difficult, although people want accurate inputting devices for touch-sensitive screens [3]. Representatively, a pen is the most common tool used as an input device and pointing tool. ...
Stylus pens are often used with mobile information devices. However, few studies have examined the stylus’ simple movements because the technical expertise to support documentation with stylus pens has not been developed. This study examined the usability of stylus pens in authentic documentation tasks, including three main tasks (sentence, table, and paragraph making) with two types of styluses (touchsmart stylus and mobile stylus) and a traditional pen. The statistical results showed that participants preferred the traditional pen in all criteria. Because of inconvenient hand movements, the mobile stylus was the least preferred on every task. Mobility does not provide any advantage in using the stylus. In addition, the study also found inconvenient hand support using a stylus and different feedback between a stylus and a traditional pen.
... For example, text entry is very similar to the keyboard of a personal computer. However, it is not intuitive for people to manipulate with a touch-sensitive screen, people want to get an accurate input device to use directly to use a touch-sensitive screen [3]. Additionally, a pen can be both an input tool and pointing tool. ...
Stylus pen is often used in documentation for a touchscreen. However, little work has been focused on stylus features to improve usability; no work has examined the effect of the full-length of stylus in creating document. In this paper, we found the satisfaction and efficiency of various stylus lengths' in creating document. Our experiment had two tasks with five styluses (7, 9, 11, 13 and 15cm). Results showed that participants can write documents with 13cm or longer styluses compared to shorter lengths. Among them, participants preferred 13cm stylus. Therefore, we suggest a stylus optimal length in creating document. The results can support the most efficient and comfortable stylus in creating document.
There have been escalating research interests on areas relating to haptic modality in recent years, especially towards mobile devices. However, there seems to be limited studies in determining the relation between haptic user interfaces and its influence on the playability of mobile games. This paper aims to measure playability of mobile games by comparing two different types of haptic interfaces, namely hard and soft keypad, for mobile gaming. The results show that the participants (N=12) scored highest in using a soft keypad (mean = 591.92, SD = 322.57) as compared to playing games using a hard keypad (mean = 471, SD = 359.29). However, this paper highlights that the majority of users prefer using the hard keypad method in virtue of greater player experience with regards to game play.
