Parkinson's disease (PD) is often responsible for difficulties in interacting with smartphones; however, research has not yet addressed these issues and how these challenge people with Parkinson's (PwP). This paper specifically investigates the symptoms and characteristics of PD that may influence the interaction with smartphones to then contribute in this direction. The research was based on a literature review of PD symptoms, eight semi-structured interviews with healthcare professionals and observations of PwP, and usability experiments with 39 PwP. Contributions include a list of PD symptoms that may influence the interaction with smartphones, a set of experimental results that evaluated the performance of four gestures tap, swipe, multiple-tap, and drag and 12 user interface design guidelines for creating smartphone user interfaces for PwP. Findings contribute to the work of re-

This study mainly aims to investigate characteristics of touch input. In addition, the touchable area that yields a specific hit rate is suggested for effective touch control. To achieve these goals, an empirical test was conducted through smart phone interface. The layout (3x4, 4x5, 5x6 and 6x8) and icon ratio (0.5, 0.7 and 0.9) were manipulated as an independent variable. A number of measurements (input offset, task completion time and preference) were utilized to assess the controllability of icon design. As a result, the layout and icon ratio were statistically significant on all three measurements. The 3x4 and 4x5 layouts were shown to have better performance. The icon ratio of 0.7 and 0.9 was also shown to have better preference. Meanwhile, the touchable area was derived based on the distribution of touch input. The general shape of the touchable area was vertically long rectangle. Based on the results of this study, the locations of the central region indicated a pattern of vertical touch and showed better performance. It was also shown that task completion time increased with an increase in the icon ratio while user preference became higher. This research is expected to contribute to practical suggestions for the interaction with an index finger.

“…Second, it is difficult for users to point at targets within their finger width. Recently, some studies on thumb use recommended that 9.2mm is the most proper width for on-screen icons [2]. Below 9.2mm, users' performance tends to degrade when they attempt to correctly select an icon on the screen with their thumb.…”

Abstract. Small touch screens are widely used in applications such as bank ATMs, point-of-sale terminals, ticket vending machines, facsimiles, and home automation in the daily life. It is intuition-oriented and easy to operate. There are a lot of elements that affect the small screen touch performance. One of the essential parts is icon feedback. However, to merely achieve beautiful icon feedback appearance and create interesting interaction experience, many interface designers ignore the real user needs. It is critical for them to trade off the icon feedback type associated with the different users needs in the touch interaction. This is especially important when the user capability is very limited. This paper described a pilot study for identifying factors that determine the icon feedback usability on small touch screen in four older adult Cognitrone groups since current research aimed mostly at general icon guidelines and recommendations and failed to consider and define the specific needs of small touch screen interfaces for the elderly. In this paper, we presented a concept from the focus on human necessity and use a cognitive assessment tool, which is, Cognitrone test, to measure older adult's attention and concentration capability and learn more about how to evaluate and design suitable small screen icon feedback types. Forty-five elder participants were participated. Each subject was asked to complete a battery of Cognitrone tests and divided into 4 groups. Each subject was also requested to perform a set of 'continuous touch' usability tasks on small touch screen and comment on open-ended questions. Results are discussed with respect to the perceptual and cognitive factors that influence older adults in the use of icon feedback on small touch screen. It showed significant associations between icon feedback performance and factors of attention and concentration. However, this interrelation was much stronger for the Group 2 and Group 4, especially for Type B, Type C and Type G. Moreover, consistent with previous research, older participants were less sensitive and required longer time to adapt to the high-detailed icon feedback. These results are discussed in terms of icon feedback design strategies for interface designers.
