Nowadays, Smart TV has been the new trend of TV landscape, which brings streaming media, personalized communication and social networking to TV screen in living room. How to add web-enhanced features to traditional TV viewing experience has been the focus of the competition in TV industry. As one of the major TV producers, Philips realizes that Smart TV calls for smart control experience, resulting in TV Fluid Control Project. Fluidity is proposed to be the durable wow experience for Philips new Smart TV remote control (RC) interaction. Touchpad-based interaction and pointer-based interaction are both promising for fluid control experience duo to their support for heads-up and lean-back viewing posture. In this project, the two interactions were compared from the perspectives of anticipated user experience (UX) and actual UX, concluding that touchpad-based interaction with uFlow user interface (UI) is more relaxing and moderate for diverse 10-foot TV consumption context. However, multiple swiping on touchpad is the main issue that degrades the fluid interaction. It is found that two-handed operation is better than one-handed operation for releasing natural and intuitive swipes. Swiping in horizontal is superior to that in vertical especially for thumb movement. The size of natural swipe revealed in this study is more than 1 cm larger than that of current touchpad on TV remote control. The criteria for touchpad-based RC were given based on user studies: remote control feeling, touchpad affordance, handholding, finger swiping, one/two-handed operation flexibility, tactile button-click interaction. The final result is the redesign of touchpad-based RC for fluid swiping UX with features as follows. A touchpad keyboard on back side for coherence of two-handed touching navigation and text entry A concave touchpad below the centre of RC on front side for comfortable and precise swipe An ergonomic shape for hand gripping to reduce the constraints of thumb movement
