Investigating User Experience Using Gesture-based and Immersive-based Interfaces on Animation Learners

Creating animation is a very exciting activity. However, the long and laborious process can be extremely challenging. Keyframe animation is a complex technique that takes a long time to complete, as the procedure involves changing the poses of characters through modifying the time and space of an action, called frame-by-frame animation. This involves the laborious, repetitive process of constantly reviewing results of the animation in order to make sure the movement-timing is accurate. A new approach to animation is required in order to provide a more intuitive animating experience. With the evolution of interaction design and the Natural User Interface (NUI) becoming widespread in recent years, a NUI-based animation system is expected to allow better usability and efficiency that would benefit animation. This thesis investigates the effectiveness of gesture-based and immersive-based interfaces as part of animation systems. A practice-based element of this research is a prototype of the hand gesture interface, which was created based on experiences from reflective practices. An experimental design is employed to investigate the usability and efficiency of gesture-based and immersive-based interfaces in comparison to the conventional GUI/WIMP interface application. The findings showed that gesture-based and immersive-based interfaces are able to attract animators in terms of the efficiency of the system. However, there was no difference in their preference for usability with the two interfaces. Most of our participants are pleasant with NUI interfaces and new technologies used in the animation process, but for detailed work and taking control of the application, the conventional GUI/WIMP is preferable. Despite the awkwardness of devising gesture-based and immersive-based interfaces for animation, the concept of the system showed potential for a faster animation process, an enjoyable learning system, and stimulating interest in a kinaesthetic learning experience

Puppetry-inspired Animation: A Midair Hand Gestures Manipulation for 3D Character Animation

Bringing together keyframe and motion-timing can be very difficult to control especially when manipulating body parts of a character animation. Both seem are ‘detach’ in their event as keyframe is physically visible, while timing is imperceptible and merely appears as substance of a sequence of keyframes. This paper presents an overview of my doctoral research, which focuses on an approach to create a puppetry-like animation technique in computer animation that provides an embodied interaction between user and animated character. The proposed project investigates how character animation acquires direct response from the user hand-centered direct manipulation using Leap Motion. Such midair motion-sensing device is used to automate keyframes that create motion timing for character animation based on the timing of a user’s movements

How I Animate: A Hand Gesture-Centric Technique

The complexity of movement requires detailed observation imagining continuous real‐time movement into fragmented keyframes that are used to construct movement in 3D computer animation. Although movement is the key element underpin every animation, however, animation remains blunt and movement merely a movement without imbuing the aesthetic of timing.We propose a novel approach to animation techniques based on hand gesture movement using motion sensing controller, Leap Motion. We investigate the depiction of timing of movement through a motion sensing device that detects hand/finger movements and gestures in midair

Wireless medical monitoring instrumentation system using fabric dipole antenna

Nowadays, most effective nurses time was spent on recording patient information data manually. By monitoring wirelessly, the nurses routine work processes can be fully automated, saving time while at the same time ensure patient care continues to remain effective and efficiency. In this paper, the 2.45 GHz monitoring system using dipole antenna is presented. The performance of Spo2 monitoring for indoor and outdoor environment is discussed and verified. The performance in outdoor environment is better compared with indoor environment
