VelociWatch: Designing and evaluating a virtual keyboard for the input of challenging text

© 2019 Association for Computing Machinery. Virtual keyboard typing is typically aided by an auto-correct method that decodes a user’s noisy taps into their intended text. This decoding process can reduce error rates and possibly increase entry rates by allowing users to type faster but less precisely. However, virtual keyboard decoders sometimes make mistakes that change a user’s desired word into another. This is particularly problematic for challenging text such as proper names. We investigate whether users can guess words that are likely to cause auto-correct problems and whether users can adjust their behavior to assist the decoder. We conduct computational experiments to decide what predictions to ofer in a virtual keyboard and design a smartwatch keyboard named VelociWatch. Novice users were able to use the features of VelociWatch to enter challenging text at 17 words-per-minute with a corrected error rate of 3%. Interestingly, they wrote slightly faster and just as accurately on a simpler keyboard with limited correction options. Our fnding suggest users may be able to type dif-fcult words on a smartwatch simply by tapping precisely without the use of auto-correct

Magic, Emotion and Practical Metabolism:Affective Praxis in Sartre and Collingwood

This article develops a new way of understanding the integration of emotions in practical life and the practical appraisal of emotions, drawing on insights from both J-P. Sartre and R. G. Collingwood. I develop a concept of ‘practical metabolism’ and show that emotions need to be understood not only as transformations from determinate to indeterminate practical intuitions, but also as transformations in the reverse direction. Firstly, I provide a new conception of the dynamic phenomenal structure of the emotions that can resolve significant tensions in the Sartre’s theory. Secondly, I develop that theory to shed light on the diverse socially mediated roles of emotions in practical life by drawing on Collingwood’s philosophy of magic. Thirdly, I deploy the notion of practical metabolism to address the appraisal of emotions, setting out a framework for understanding the various ways in which emotional expression is subject to structural breakdown

Hermeneutic Phenomenology meets Transformative Learning

The research methods that have been employed in the latest studies on transformative learning are several. This diversity can be considered as a strength insofar as each method, with its underlying philosophy of research, has contributed to the enhancement of transformative learning, namely disclosing new insight
