—A MAG-µIMU which is based on MEMS accelerometers, gyroscopes and magnetometers has been developed for real-time estimation of human hand motions. Appropriate filtering, transformation and sensor fusion techniques are combined in the Ubiquitous Digital Writing Instrument (UDWI) to record the handwriting on any surface. However, because of the sensors'(More)

This paper examines the effectiveness of employing precomputation techniques to reduce power consumption of field configurable computing systems. Multiplier is modified with precomputation techniques and are implemented using commercial off-the-shelf FPGAs. Precomputation techniques reduce dynamic power consumption of a module by eliminating unnecessary(More)
We have recently developed a ubiquitous digital writing instrument system based on a micro inertial measurement unit (mulMU), which consists of MEMS (micro- electro-mechanical system), accelerometers and gyroscopes, to compute the position of a marker through double integration of the acceleration measured, so as to real-time record and recognize human(More)
A micro inertial measurement unit (μlMU) which is based on Micro-Electro-Mechanical Systems (MEMS) accelerometers and gyroscope sensors is developed for real-time recognition of human hand motion. By using appropriate filtering, transformation and sensor fusion algorithms, a ubiquitous digital writing instrument is produced for recording handwriting(More)
