This study presents a smart remote controller (SRC) framework for the Android. The Android mobile device acts as the client side of the proposed SRC software. The software uses intuitive dynamic user operation modes to send remote control commands to the controlled side by leveraging the multi-touch events, gesture recognition and hand gesture features of the Android device. The remote controlled server side is based on a Java framework. This facilities portability to PCs or networked information appliances such as Internet TVs, thus, allowing users to establish connections and translate events to control corresponding programs or actions. In this design of the proposed SRC, advanced features are categorized into various modes that can be applied to the scenarios offices and digital homes.

Multitransform techniques have been widely used in modern video coding and have better compression efficiency than the single transform technique that is used conventionally. However, every transform needs a corresponding hardware implementation, which results in a high hardware cost for multiple transforms. A novel method that includes a five-step operation sharing synthesis and architecture-unification techniques is proposed to systematically share the hardware and reduce the cost of multitransform coding. In order to demonstrate the effectiveness of the method, a unified architecture is designed using the method for all of the six transforms involved in the H.264 video codec: 2D 4 × 4 forward and inverse integer transforms, 2D 4 × 4 and 2 × 2 Hadamard transforms, and 1D 8 × 8 forward and inverse integer transforms. Firstly, the six H.264 transform architectures are designed at a low cost using the proposed five-step operation sharing synthesis technique. Secondly, the proposed architecture-unification technique further unifies these six transform architectures into a low cost hardware-unified architecture. The unified architecture requires only 28 adders, 16 subtractors, 40 shifters, and a proposed mux-based routing network, and the gate count is only 16308. The unified architecture processes 8 pixels/clock-cycle, up to 275 MHz, which is equal to 707 Full-HD 1080 p frames/second.

This study adopts usability evaluation method for evaluating the user's acceptance of a Cloud Computing based context-aware Personal Healthcare Records (PHR). The system features include basic phys-iological measurement, life style management, etc. It exploits the so called “polling scheme for Bluetooth” and multi-device automatically reading physiological measurements to achieve the efficacy of context-aware. Moreover, the entire personal health records can be transmitted synchronously into a Cloud system in real time. To evaluate the usability, we conduct an experimental test on the prototype system. We recruit 100 par-ticipants for the evaluation. The study results show that the participants have high rating of positive response to the system usability.
