Diary-Like Long-Term Activity Recognition: Touch or Voice Interaction?
Philipp Scholl, Marko Borazio, Martin Jansch, Kristof Van Laerhoven · 2014
The experience sampling methodology is a well known tool in psychology to asses a subject's condition. Regularly or whenever an important event happens the subject stops whatever he is currently involved in and jots down his current perceptions, experience, and activities, which in turn form the basis of these diary studies. Such methods are also widely in use for gathering labelled data for wearable long-term activity recognition, where subjects are asked to note conducted activities. We present the design of a personal electronic diary for daily activities, including user interfaces on a PC, Smartphone, and Google Glass. A 23-participant structured in-field study covering seven different activities highlights the difference of mobile touch interaction and ubiquitous voice recognition for tracking activities.
