The document summarizes the design process for an app that maps users' emotions to photos based on geolocation. It describes initial goals of simplicity and insight. Participatory sessions focused on ease of use. The concept evolved to map emotion by geolocation. User testing provided feedback to improve the home screen and explain the emotion/color mapping. The final app allows taking photos, viewing locations on a map, and exploring photos in a gallery. Potential improvements include cloud storage, better gallery integration, and future technologies like augmented reality.
