This paper presents several conceptual approaches for improving user engagement and happiness in mass transport systems by effectively integrating principles of ambient and aesthetic intelligence. We introduce themed passenger carriages as constructed spaces with an overarching topic or narrative, designed to make commuting a meaningful and immersive experience. We examine the challenges for commuters and the existing solutions. Following which, we develop scenarios related to the fields of recreation, culture, education, business and entertainment. With an increasing interest of policy-makers in the concept of happiness as a socioeconomic measure for national wellbeing, we identify generic approaches for future research. (C) 2015 The Authors.
