The popularity of various wireless communication applications is crowding the radio spectrum. As an alternative medium, the visible light spectrum is be- ing exploited. Camera-based visible light communication systems are gaining much attention due to the widespread use of smartphones equipped with small embedded cameras. Screens (e.g., liquid...

This thesis introduces LightDigit, a recognition system for fingertip air-writing digits that enables low-cost, privacy-preserving, and in air interaction with pub- lic devices such as touchscreens. The current LightDigit prototype can input digits to public devices with a simple array of photodiodes and with ubiquitous ambient light in our...

Passive visible light communication (VLC) takes advantage of the pervasive<br/>nature of ambient light in our environment for wireless transmissions. The<br/>design of transmitters in passive VLC predominantly uses Liquid Crystal Displays (LCD’s). While LCD’s are an economical choice with low power consumption, they lack some key properties that...

Solar cells are usually used as power source, but can be used for sensing as well. We propose a novel indoor tracking system that tracks people by using the change in output caused by their shadows. First, we develop a simulator to determine how the solar cells should be positioned in the tracking environment to get the best detection rate. This...

Many wheelchair users actively engage in wheelchair sports, for instance in the Paralympics. Trainers increasingly use the developments in sports technology for analysis. But wheelchair athletes do not benefit as much from these developments. A wheelchair can, for instance, disturb signal transmission. Recently, a set of studies describe the...

Ever since its invention in the 1930s, photoplethysmography (PPG) is a wide-spread technique used for health-monitoring. Via illumination of the human skin with a light source and capturing the light, an estimate of important physiological properties such as the heart rate can be made. This is commonly done with dedicated medical equipment, but...

The IoT contains billions of interconnected devices and is only growing larger by the day. These devices often need to operate for years while keeping mobile objects, such as animals or vehicles, connected to a larger system. Therefore they will be battery-powered, energy efficient and, their position will be tracked. Therefore, connecting these...

The idea of having a smart environment to automate day to day tasks appeals to us all. To enable this, we need objects with embedded electronics to communicate with each other in a network known as the Internet of Things (IoT). The IoT communication infrastructure is built on top of existing Radio Frequency (RF) technologies such as Bluetooth...

Nowadays, 19% of the global energy consumption is used for lighting. For this reason, saving energy in lighting is vital. A simple way to save energy is to “simply” turn the lights off, or reduce the amount of light used when nobody is around. This thesis proposes a new method for luminaires to detect the presence of humans and objects which...

The idea of the internet of things (IoT) states that devices with embedded electronics will outnumber the devices operated by humans. All those "things" will require connectivity to exchange information gathered from processed sensor data. A large part of the data will be sent through the air, such that mobile devices can be deployed without a...

A growing number of wireless devices and increasing traffic in the radio spectrum has pushed for alternatives to radio based communication. Among these, communication using visible light (VLC) has gained considerable momentum. The imminent adoption of energy efficient Light Emitting Diodes (LEDs) and the high data transmission rates offered by...

In commercial buildings, smart lighting control systems are applied to minimize the electrical energy consumption. These systems use occupancy and light sensor data to adapt artificial light in accordance with changing occupancy and daylight conditions. In these systems, the performance relies on a pre-calibration phase to achieve daylight...

The way people meet each other is usually face to face. Meanwhile, the way people maintain their contacts is mostly through social media. This results in a gap of translating a handshake into a digital connection. Shake-On is a start-up that has come up with an answer by means of a smart bracelet. Their aim is to wirelessly exchange contact...

In a modern environment users are more dependant on their ability to use their mobile phone for nearly everything. They communicate with almost any device and those devices provide nearly limitless access to for instance a watch or in new applications, a lock. Issues encountered with these devices are the almost always lack the ability to keep...

Traditionally, link quality estimation (LQE) has been viewed as an a priori step in sensor network routing protocols because it filters out unreliable links before data transmission. Recent results, however, show that protocols can perform well without a priori LQE. Because getting rid of LQE seems rather counter-intuitive, the aim of this work...
