How are you using your smartphone or tablet? An observational tool

摘要

The last 30 years have seen major technological advances in computing technology. Many people now routinely carry computing power in their hands that would previously have occupied a room. This paper reports on an observational tool being developed as part of a study of the use of smartphones and tablets amongst workers in Singapore, and any associated health issues. The tool will allow an observer to make a quick visual posture assessment of a smartphone or tablet user.
