v Study adherence tends to increase significantly when moving from paper to mobile formsv Moral: Do not innovate without a good reason
qThe traditional design in mobile form (e-Paper) gave the best results
v Expand the study to pathological subjects
v Analyze the disorder factor in study adherence
e-Paperv ObjectivesqDevelop an app for interpersonal circumplexqTest conventional and novel interfaces
against the paper controlv Methods
q Adherence [on-time reporting? yes/no]q Time performanceq Redundant tapsq Subjective feedback
