Presenting personalized recommendations : how interfaces should reveal what they know about users
Abstract/Contents
- Abstract
- The present age of digital commerce affords many of the key wins of the previous two stages (local and mass) and also allows new opportunities to provide a personalized experience to consumers. Abstracting the key elements of the interaction between retailers and customers that make it feel personalized offers a guiding framework for taking digital commerce to its apex: 1) Gather user information and needs, 2) Build user model and profile, 3) Match user with appropriate available content, and 4) Present personalized content. This framework offers an approach for extracting the lessons learned from the two previous stages of media evolution as well as from social science and human-computer interaction to make digital consumer experiences feel more personal. This dissertation focuses on the last step of this personalization cycle and details empirical evidence tackling how interfaces should reveal what they know about users in the context of affective computing systems for emotion-based adaptation. The first experiment uncovered how a personalized interface should respond to users when it has detected they are feeling either happy or sad and the consequences for revealing it has made an inaccurate assessment. Experiment 1 was a 2 (Mood Induced: happy or sad) by 2 (Feedback Accuracy about Emotion Detection: accurate or inaccurate) by 2 (Recommendation Sentiment: happy or sad) between-subjects experiment on the web (N = 96). The results illuminated that feedback accuracy and the congruency of recommendation sentiment have different effects for happy and sad users. The second experiment investigated how a personalized interface should respond to frustrated users. Experiment 2 was a 2 (Source: internal or third party) by 2 (Blame Attribution: user or system) by 2 (Recommendation Difficulty: easy or hard) between-subjects experiment on the web (N = 96). The results stress that it is critical for systems to avoid patronizing users when they are frustrated. These experiments and the larger personalization framework offer design implications for the numerous cross-functional teams working in this space. They also suggest directions for future research aiming to uncover insights to advance the user experience of personalized recommendation systems.
