“…Despite these advantages, and the fact that touchscreens and software keypads are often preferred to other pointing devices [17,44,50,52], or to alternative input methods, including handwriting [25], or speech recognition [51], especially by novice users, this study also revealed some ergonomic and usability problems. The first problem commented on by participants was arm fatigue.…”

“…Lack of tactile feedback may be compensated for by providing users with alternative feedback [43,52]. Touchscreen driver software by ELO touchsystems could provide auditory feedback with short click sounds (which may be turned off if the user prefers), whereas the software keypad package by NTT PC Communications has a function to highlight the selected key.…”

“…The first problem commented on by participants was arm fatigue. The touchscreen is well known for its potential to cause arm fatigue [19,36,40,52]. The surface of the terminal used in this study was placed at approximately 75°to the horizontal, and this steep screen angle is considered to be the main reason for the arm fatigue [40].…”

Lowering elderly Japanese users? resistance towards computers by using touchscreen technology

The standard qwerty keyboard is considered to be a major source of reluctance towards computer technology use by Japanese elderly, due to their limited experience with typewriters and the high cognitive demand involved in inputting Japanese characters. The touchscreen enables users to enter Japanese characters more directly and is expected to moderate this resistance. An e-mail terminal with a touchscreen was developed and compared with the same terminal using a standard keyboard and mouse. Computer attitudes and subjective evaluations of 32 older adults were measured. The results showed that the anxiety factor of computer attitudes declined significantly in the touchscreen condition.

“…Yet even though Daniel the second generation of commercial direct pen input devices such as the Tablet PC, where the input and output spaces are coincident (Whitefield, 1986), are now cost effective and readily available, they have failed to live up to analysts' prediction for marketplace adoption (Spooner & Foley, 2005;Stone & Vance, 2009). Relying on text entry without a physical keyboard could be one factor, but part of the problem may also be that current software applications and graphical user interfaces (GUIs) are designed for indirect input using a mouse, where there is a spatial separation between the input space and output display.…”

“…One reason for the lack of pen-specific commercial applications is that the primary adopters of pen computing are in education, healthcare, illustration, computeraided design, and mobile data entry (Chen, 2004;Shao et al, 2007;Whitefield, 1986) in spite of initial expectations that business users would be early adopters. These vertical Downloaded by [University Of Maryland] at 01:20 14 October 2014 markets use specialized software that emphasizes handwritten input and drawing, rather than general computing.…”

We examine the usability and performance of Tablet PC direct pen input with a conventional graphical user interface (GUI). We use a qualitative observational study design with 16 participants divided into 4 groups: 1 mouse group for a baseline control and 3 Tablet PC groups recruited according to their level of experience. The study uses a scripted scenario of realistic tasks and popular office applications designed to exercise standard GUI components and cover typical interactions such as parameter selection, object manipulation, text selection, and ink annotation. We capture a rich set of logging data including 3D motion capture, video taken from the participants' point-of-view, screen capture video, and pen events such as movement and taps. To synchronize, segment, and annotate these logs, we used our own custom analysis software.We find that pen participants make more errors, perform inefficient movements, and express frustration during many tasks. Our observations reveal overarching problems with direct pen input: poor precision when tapping and dragging, errors caused by hand occlusion, instability and fatigue due to ergonomics and reach, cognitive differences between pen and mouse usage, and frustration due to limited input capabilities. We believe these to be the primary causes of nontext errors, which contribute to user frustration when using a pen with a conventional GUI. Finally, we discuss how researchers could address these issues without sacrificing the consistency of current GUIs and applications by making improvements at three levels: hardware, base interaction, and widget behavior.

Interaction with an autostereoscopic touch screen: effect of occlusion on subjective experiences when pointing to targets in planes of different depths

It is well known that the usability of a typical touch screen depends on several parameters, including interface design, device characteristics, and input operations. However, there is virtually no knowledge regarding how people evaluate interaction with 3D display‐integrated touch screen. Twenty‐one participants were asked to use standard touch screen to point to targets in planes of different planes on an autostereoscopic display and evaluate how natural and easy this action was. Clear differences in pointing experiences across depth levels and input operators were found. Pointing to targets in a back plane was reported to be more natural and easier than the same action with targets in a front plane. The use of finger input was less unnatural than the use of a stylus, but the use of stylus with icons in the front plane was more fun and entertaining.
