Abstract:In this graduation project, the potential and implementation of three-dimensional capacitive sensing technology in wearable technology is explored. To give this project a clear scope, the potential of this technology is defined through its satisfaction in three requirements: the technology should be advantageous to other forms of Human Computer Interaction in specific contexts, the technology should be accessible for the Creative Technology bachelor programme of the University of Twente and the technology should be implementable in a form of wearable technology. The satisfaction of these requirements is evaluated through multiple methods. First, a state of the art and background research. Then, development of an exemplary prototype implementing the provided MGC3130 Hillstar development Kit, provided by MicroChip®, in a piece of wearable technology. A goal is set to evaluate the provided sensor set; get the dev-kit working, form a communication between the system and an accessible open source program, and create an interesting, meaningful interaction. This interaction is realized in the development of a touchless computer supported presentation controller using a pair of programmed Arduino Micro MCU utilizing wireless 2.4GHz RF transmission. Through the development of this exemplary prototype, including user- and prototype-testing, along with implicit research, it is found that this technology is accessible for developers, specifically students of the Creative Technology programme, and shows potential to be implemented in future products or projects. Additionally, from state of the art and background research, three-dimensional capacitive gesture recognition technology is found to be advantageous over multiple other forms of human-computer interaction or other forms of gesture recognition technology. Limitations in interaction and comfort as a wearable have been found due to body noise interference and electrode size, respectively. To solve this, extended electrode customization and future research is recommended.
