Hacking The Nintendo Wii Remote
Johnny Chung Lee in this paper discuss about the sophisticated use of Wii Remote, instead Wii Remote use only in playing game. Although Nintendo doesn't release the official specification ,The Global Community Hacker already, release unofficial Wii specification by doing a reverse engineering the Wii Remote (the source is in www.wiibrew.org). With its outperform ability, Chung Lee shows in this paper the use of Wii Remote that never intended, such as as a Finger and Object Tracking application, Interactive Whiteboard and Tablet Display, Head Tracking for Desktop VR, and Spatial Augmented Reality. The later discussion John Chung Lee describe, the future development program using Wii Remote such as 3D motion tracking, Tracking objects with ID, IR glyphs, Laser tag, and Gesture recognition.
After reading this paper, we can conclude that the advantages ability of the Wii sensor such as:
1. Outperforming application .
2. Can widely connect to another device, since using bluetooth.
3. Relatively low price comparing to another single sensor.
It is may use in several pervasive computing system such as sensor for for house-gate system, sensor for parking gateway, sensor for ticketing, etc. It is when we add tracking ID, we can use that ID to recognize our self in pervasive system.

MobiUS: Enable Together-Viewing Video Experience across Two Mobile Devices
This paper describes the development of together-viewing video application in mobile device with real-time and synchronous decoding. The challenge doing a together viewing by establishing a half-frame video in mobile device is because mobile device has a limitation in computing complexity, bandwidth efficiency and also power consumption. The together-viewing scenario may useful in mobile gaming view (put side by side viewing) and collaborative mobile. The author in this paper has successfully applied the method in 2 mobile devices. This is by the assumption, if it success in this 2 mobile device, the next development can applied in several mobile device also in more modifications. The author is also publishing the system architecture for implementing the half-frame video.
My comment, the success of this research for as a stepping stone to create another chalangging application such as realtime-interactive gamming for more than 1 player, hence players viewing togeteher same scene realtime. In other cases, the example is viewing higer resolution video by joining devices together.
However, there future next development of this method should over come such as:
1. Create an open standard for together-viewing via mobile
2. Enhance the application for more than 2 device (an n-device)
3. Enhance the application for non-homogeny device (including screen)
4. Overcome a sudden-off of any device. This is especially for overcoming a sudden-off of left-device (left device to control partial-bit-stream)
5. How to remove extra band but still performing CDC traffic by (76%), although it is only give extra computing consumption about 7%.
6. Handling low-connectivity on the streaming transfer
