“…Stone proposed a special free text input method for elderly people [17]. There have been some accessibility-related evaluations of mobile touchscreens for visuallyimpaired or motor-impaired users [18] [19]. Stößel et al compared older users and younger users in how they interacted with touchscreens including multi-touch systems.…”

Abstract. Smartphones with touchscreen-based interfaces are increasingly used by non-technical groups including the elderly. However, application developers have little understanding of how senior users interact with their products and of how to design senior-friendly interfaces. As an initial study to assess standard mobile touchscreen interfaces for the elderly, we conducted performance measurements and observational evaluations of 20 elderly participants. The tasks included performing basic gestures such as taps, drags, and pinching motions and using basic interactive components such as software keyboards and photo viewers. We found that mobile touchscreens were generally easy for the elderly to use and a week's experience generally improved their proficiency. However, careful observations identified several typical problems that should be addressed in future interfaces. We discuss the implications of our experiments, seeking to provide informal guidelines for application developers to design better interfaces for elderly people.

“…The overload of the visual channel makes it difficult to use these devices when engaged in a secondary task, such as walking, attending a meeting, or shopping. Furthermore, the inability to use these devices in an eyes-free manner affects people with visual impairments [10].…”

-We present an eyes-free text entry technique for touchscreen mobile phones. Our method uses Graffiti strokes entered using a finger on a touchscreen. Although visual feedback is present, eyes-free entry is possible using auditory and tactile stimuli. In eyes-free mode, entry is guided by speech and non-speech sounds, and by vibrations. A study with 12 participants was conducted using an Apple iPhone. Entry speed, accuracy, and stroke formations were compared between eyesfree and eyes-on modes. Entry speeds reached 7.00 wpm in the eyes-on mode and 7.60 wpm in the eyes-free mode. Text was entered with an overall accuracy of 99.6%. KSPC was 9% higher in eyes-free mode, at 1.36, compared to 1.24 in eyes-on mode.

“…Unfortunately, as discussed by McGookin et al [1], the creation of accessible modifications and enhancements for touch-based devices is lagging behind the breakneck pace of mainstream development. Touchscreens pose an especially daunting challenge for blind or visually impaired users.…”

Abstract. Mobile devices with multi-touch capabilities are becoming increasingly common, largely due to the success of the Apple iPhone and iPod Touch. While there have been some advances in touchscreen accessibility for blind people, touchscreens remain inaccessible in many ways. Recent research has demonstrated that there is great potential in leveraging multi-touch capabilities to increase the accessibility of touchscreen applications for blind people. We have created No-Look Notes, an eyes-free text entry system that uses multi-touch input and audio output. No-Look Notes was implemented on Apple's iPhone platform. We have performed a within-subjects (n = 10) user study of both No-Look Notes and the text entry component of Apple's VoiceOver, the recently released official accessibility component on the iPhone. No-Look Notes significantly outperformed VoiceOver in terms of speed, accuracy and user preference.
