Selfie Guidance System in Good Head Postures

Taking selfies has become a popular and pervasive activity on smart mobile devices nowadays. However, it is still difficult for the average user to take a good selfie, which is a time-consuming and tedious task on normal mobile devices, especially for those who are not good at selfies. In order to reduce the difficulty of taking good selfies, this work proposes an interactive selfie application developed with multiple user interfaces to improve user satisfaction when taking selfies. Our proposed system helps average users take selfies by providing visual and voice guidance interfaces on the proper head postures to achieve good selfies. Preprocessing through crowdsourcing-based learning is utilized to evaluate the score space of possible head postures from hundreds of virtual selfies. For the interactive application, we adopt a geometric approach to estimate the current head posture of users. Our user studies show that the proposed selfie user interface can help common users taking good selfies and improve user satisfaction.
