Beyond the switch: explicit and implicit interaction with light

The commercial introduction of connected lighting that can be integrated with sensors and other devices is opening up new possibilities in creating responsive and intelligent environments. The role of lighting in such systems goes beyond simply functional illumination. In part due to the large and established lighting network, and with the advent of the LED, new types of lighting output are now possible. However, the current approach for controlling such systems is to simply replace the light switch with a somewhat more sophisticated smartphone-based remote control. The focus of this workshop is to explore new ways of interacting with light where lighting can not only be switched on or off, but is an intelligent system embedded in the environment capable of creating a variety of effects. The connectivity between multiple systems and other ecosystems, for example when transitioning from your home, to your car and to your office, will also be explored during this workshop as a part of a connected lifestyle between different contexts.

Methods for measuring work surface illuminance in adaptive solid state lighting networks

The inherent control flexibility implied by solid-state lighting - united with the rich details offered by sensor networks - prompts us to rethink lighting control. In this research, we propose several techniques for measuring work surface illuminance and ambient light using a sensor network. The primary goal of this research is to measure work surface illuminance without distraction to the user. We discuss these techniques, including the lessons learned from our prior research. We present a new method for measuring the illuminance contribution of an arbitrary luminaire at the work surface by decomposing the modulated light into its fundamental and harmonic components.Massachusetts Institute of Technology.

Power-managed smart lighting using a semantic interoperability architecture

Abstract-This paper presents a power-managed smart lighting system that allows collaboration of lighting consumer electronics (CE) devices and corresponding system architectures provided by different CE suppliers. In the example scenario, the rooms of a building are categorized as low and high priority, each category utilizing a different system architecture. The rooms collaborate through a semantic interoperability platform. The overall smart lighting system conforms to a power quota regime and maintains a target power consumption level by automatically adjusting lights in the building

How smart work environment applications can add strategic value

The way people work has changed and many corporate real estate (CRE) and facility managers (FM) are thinking about whether and how to implement smart-building applications in the work environments of their client. The data collected by these applications can be a valuable asset, however it is necessary to identify beforehand which type of data collection could provide which strategic value(s). Therefore, this study examined the expected strategic value of specific smart work environment applications for organizations from the perspective of CRE and FM professionals. A questionnaire was developed based on existing literature. In total, 122 CRE and FM experts participated and provided their perception of 20 different applications and 9 different strategic values. During follow-up expert interviews, the practical implications of the findings were discussed and translated into recommendations. The smart applications that are expected to decrease real estate costs mostly relate to the automatization of facility services. Employee satisfaction is particularly supported by smart applications related to personal preferences and personalization (e.g. temperature control, smart coffee machine). The smart applications that are expected to support productivity mostly concerned either features of the work environment (automatic printer and meeting room allocation), ways to eliminate negative conditions (noise cancelling), or support in finding colleagues elsewhere in the building. Although many studies have proven the effect of physical work environment characteristics on employees and/or on organizations, there is little insight into the effect of smart work environment applications on both. This paper has started to build theory on smart building applications. The findings in this paper are also relevant for CRE and facility managers and consultants as they provide insight in what their colleagues expect of different available smart work environment technology applications, to support their own decision making

Discovery, monitoring and management in smart spaces composed of low capacity nodes

This paper introduces a lightweight architectural solution for discovery, monitoring and management of nodes, services and resources in smart spaces composed of low capacity nodes. A wireless sensor network software architecture is used as the baseline and is extended to a scalable smart space architecture. Discovery, monitoring and management tasks are realized by means of a Resource Manager that acts as just another node. The proposed architecture is deployed on physical wireless sensor nodes. Experimental results show that the proposed smart space architecture is indeed lightweight and suitable for very low capacity nodes. Keywords: Lightweight smart space architecture, low capacity node, service discovery, resource discovery

LiFi and its integration with the internet of the things

En el documento, se lleva a cabo una revisión de la literatura sobre la comunicación por medio de la luz visible conocida como Light Fidelity (LiFi, por sus siglas en inglés) y el internet de las cosas (IoT, por sus siglas en inglés). Para lo anterior, se usa una metodología cualitativa de tipo descriptivo, con el fin identificar el funcionamiento de la tecnología LiFi; las ventajas y desventajas que presenta frente a otras tecnologías existentes; y los principios de funcionamiento y oportunidades de la integración de la internet de las cosas con LiFi como uno de los pilares de desarrollo para las ciudades inteligentes. Las conclusiones de la revisión apuntan a que la integración de bombillas LED (Diodo Emisor de Luz) con tecnología LiFi a redes IoT y servicios en la nube, permitirá el fortalecimiento de la iluminación LED conectada donde se aportan nuevos conocimientos y se puede considerar la iluminación como un servicio.In the document, a review of the literature on communication through visible light known as Light Fidelity (LiFi) and the Internet of Things (IoT) is carried out.For the above, a qualitative methodology of descriptive type is used, in order to identify the operation of LiFi technology; the advantages and disadvantages that it presents compared to other existing technologies; and the principles of operation and opportunities for the integration of the internet of things with LiFi as one of the pillars of development for smart cities.
