AIR QUALITY IN OFFICES
The effect of different environmental variables is a particularly busy area for research. However my research as part of the ReFresh Project is some of the first which has looked into how social factors such as individual preferences, office dynamics and workplace relations can affect decisions around air quality and in turn, directly affect the air quality of offices e.g. over-heating and carbon dioxide build up in winter. Resulting poster and papers published to date from this work are below, and my blog post on this subject is here.

RAISING AWARENESS OF AIR QUALITY IN OFFICES USING SENSOR NETWORKS
I have supervised two electronic design undergraduate projects, one of which sought to prototype and design an in-office display to improve employee awareness of indoor air quality.
Aether- situated awareness of indoor air quality
The journey toward the Aether began with a process of contextual enquiry, qualitative interviews and prototype development towards the final product featured below. The Aether represents an impressive design and build project for single 3rd year project student. The system uses a Rasberry Pi Zero to drive sensors for CO2, temperature and humidity and display the values on a LCD. Ambient lighting curtousy of a WS2812B ring changes with increasing CO2 levels from green to orange to red. The casing is an original design which has been 3D printed. The aim of the Aether is to develop a better understanding how people use air quality information and whether such devices lead to healthier ventilating behavior.
THE COGNITIVE & PHYSIOLOGICAL EFFECTS OF CO2 IN OFFICES
Recent research suggests that poor ventilation in naturally ventilated offices of meeting rooms can have a negative effect on cognition and drowsiness. We are attempting to replicate the carbon dioxide levels of a stuffy office by means of introducing ultra-pure CO2 into a room from a cylinder. In this envionment we are measuring people's brain activity using electroencephalogram (EEG) and physiological signals such as skin temperature, respiration, heart rate and blood-oxygen using electrocardiogram (ECG). The first protocol involved 42 subjects, for which we are now writing up this work into a full length journal paper.
The second protocol involved a counter-balanced design including EEG and a cognitive performance test battery. We are presently analysing results from the 31 subjects.
Ambient lighting curtousy of a WS2812B ring changes with increasing CO2 levels from green to orange to red. The casing is an original design which has been 3D printed. The Aethers has been deployed in 11 offices (to date), with questionnaires and qualitative interviews following on from each deployment to understand factors affecting engagement and the potential for the Aether to prompt healthier ventilation behaviours. The project is currently being written up as a full length journal article.
ColourCool- networked office air quality monitors
ColourCool is the product of a team of four 4th year students. It comprises an expandable wireless sensor network of currently two air quality monitors which measure CO2, temperature and humidity and display the information via a server to a user interface accessible by a login/password combination specific to a given office. Two ColourCool sensors have been deployed in a local Southampton tax and accountancy firm for a 5 week deployment. ColourCool was developed with a custom-made PCB to minimise power consumption and size.
The user interface is built on FireBase with colour-coding of CO2 levels to inform occupants of when the CO2 is good (green), high (yellow) or at levels likely to cause lost productivity (red). Office occupants can see readings from both sensors in their office on the one webpage, which they can access in the same way as any other URL. ColourCool was deployed in a Southampton accountancy office over the winter of 2016/2017. It was found having air quality information available to office workers provokes conversations within the office about air quality and leads to any changes in ventilation behaviour by occupants.
SOCIAL CONTEXT OF MONEY
Australia is one of the most expensive countries to live in the world. In this research we explored the social contexts of money. We used contextual interviews and ran a large participatory design workshop in partnership with a local non-profit organisation. The aim of the interviews and workshop was to understand the barriers and facilitators of how people live well on less and to inform the design of technology to meet the information needs of the organisations' clients.
The papers resultant from this research detail the various and creative ways that people on a various levels of income income saved money, shared with others and lived well. We highlight the limitations of traditional budgeting apps and instead provide implications for the design of sharing economy platforms which may provide means supporting people getting by on limited financial means.
SMART THERMOSTAT DESIGN
My colleague Fred Auffenberg designed and built a participatory sensing system allowing office occupants to register their thermal comfort as input into smart thermostat learning algorithm. This involved the placement of over 100 posters around a floor of an office building and four floors of a library.
Following the deployment I conducted 13 in-depth interviews with occupants in the office deployment about their use of the system, motivations behind logging their thermal comfort and insight into what we noticed was a profound "novelty effect" during the deployment. People would log their thermal comfort regularly at the beginning and then forget to or simply stop. This research led to two publications:
