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.

Empirical Investigation into the Effect of Orientation on Text Readability in Tabletop Displays

Tabletop collaborative groupware is a newly re-emerging field in CSCW. The use of a tabletop display presents a unique challenge to interface designers: how to optimally orient displayed objects for viewing and manipulation by users situated at various locations around the table. A great deal of CSCW research has been conducted under the implicit assumption that textual elements should be oriented directly toward the reader, despite research that demonstrates that a simple, straight-on orientation is not necessarily ideal in all circumstances. Absent from this ongoing research dialogue, however, has been an empirical examination of user performance of reading text on tabletop displays at non-zero orientations. In this paper, we present two studies which examine the effect of text orientation on common tasks: the reading of a small piece of text, and the serial search for a label. We found that, though statistically significant, the effects of orientation on the performance of these tasks were less dramatic than might have previously been assumed. From this, we hope to help guide collaborative groupware designers as to when orientation should be "corrected".

Haptic Feedback Intensity Affects Touch Typing Performance on a Flat Keyboard

Abstract.We study the effect of haptic feedback intensity on touch typing performance on a flat keyboard. In this study, we investigate how local and global haptic feedback intensities affect typing performance and examine if haptic feedback at a higher intensity brings more performance benefit. We also investigate if auditory feedback intensity affects typing performance. Participants are asked to type on a flat keyboard with given texts on a computer screen. We measure typing performance in terms of typing speed, efficiency and error rate at different intensity levels for both haptic and auditory feedback. The results show that the intensity of haptic feedback affects typing performance while the intensity of auditory feedback does not. Our findings suggest that haptic feedback is beneficial to typing performance and its intensity should be carefully chosen in designing a flat keyboard.Keywords: haptic feedback intensity, auditory feedback intensity, touch-typing performance, flat keyboard, zero-travel keyboard, touchscreen IntroductionThe present study is part of an on-going investigation of how visual, auditory and haptic keyclick feedback affects typing performance in general and touch typing on a flat surface in particular. As touchscreen devices like smartphones and tablet PCs are becoming more pervasive, finger typing on a flat keyboard (either a virtual keyboard on a glass or a slim keyboard that serves as a touchscreen cover) is commonplace. With a larger screen size, people are able to touch type with multiple fingers instead of tapping with a single finger. It is however difficult to type on a flat keyboard because of the lack of sensory feedback. Our recent work studied how multi-finger touch typing performance depends on different types of sensory feedback that are available on a flat keyboard [1]. We found that localized haptic keyclick feedback (feedback on the typing finger only) resulted in the highest typing speed and the lowest total error rate among other types of feedback conditions. Furthermore, we also found through preliminary testing that higher haptic feedback inten-
