DigiDress: A Field Trial of an Expressive Social Proximity Application

Per Persson, Jan Blom, Younghee Jung

Lecture Notes in Computer Science > UbiComp 2005: Ubiquitous Computing > 195-212

In May 2005 Nokia Sensor application (www.nokia.com/sensor) was launched, allowing mobile phone users to create digital identity expressions, seen by other users within Bluetooth range. This paper describes the design and mass-scale longitudinal field trial of a precursor prototype called DigiDress. 618 participants voluntarily used the application for an average of 25 days. The identity expressions...

Development of an economic rearing and transport system for an arid-adapted strain of the predatory mite, Neoseiulus californicus, for spider mite control

Eric Palevsky, Phyllis G. Weintraub, Einat Zchori-Fein, Shira Gal, more

Trends in Acarology > Agricultural Acarology: Biological Control > 425-429

Neoseiulus californicus (McGregor) is a relatively effective phytoseiid predator against spider mites reported from the Americas (North and South), Africa, the Mediterranean basin, and Japan. This study was a collaborative effort to identify and mass-rear a strain of N. californicus that is more efficacious under arid conditions than the standard commercial strain from California (USA)....

From big smartphone data to worldwide research: The Mobile Data Challenge

Juha K. Laurila, Daniel Gatica-Perez, Imad Aad, Jan Blom, more

Pervasive and Mobile Computing > 2013 > 9 > 6 > 752-771

This paper presents an overview of the Mobile Data Challenge (MDC), a large-scale research initiative aimed at generating innovations around smartphone-based research, as well as community-based evaluation of mobile data analysis methodologies. First, we review the Lausanne Data Collection Campaign (LDCC), an initiative to collect unique longitudinal smartphone dataset for the MDC. Then, we introduce...

Mining large-scale smartphone data for personality studies

Gokul Chittaranjan, Jan Blom, Daniel Gatica-Perez

Personal and Ubiquitous Computing > 2013 > 17 > 3 > 433-450

In this paper, we investigate the relationship between automatically extracted behavioral characteristics derived from rich smartphone data and self-reported Big-Five personality traits (extraversion, agreeableness, conscientiousness, emotional stability and openness to experience). Our data stem from smartphones of 117 Nokia N95 smartphone users, collected over a continuous period of 17 months in...

Discovering places of interest in everyday life from smartphone data

Raul Montoliu, Jan Blom, Daniel Gatica-Perez

Multimedia Tools and Applications > 2013 > 62 > 1 > 179-207

In this paper, a new framework to discover places-of-interest from multimodal mobile phone data is presented. Mobile phones have been used as sensors to obtain location information from users’ real lives. A place-of-interest is defined as a location where the user usually goes and stays for a while. Two levels of clustering are used to obtain places of interest. First, user location points are grouped...

Characterization of nitric oxide signaling pathways in the mouse retina

Jan Blom, Tom Giove, Monika Deshpande, William D. Eldred

Journal of Comparative Neurology > 520 > 18 > 4204 - 4217

Nitric oxide (NO) is a gaseous neuromodulator with physiological functions in every retinal cell type. NO is synthesized by several nitric oxide synthases (NOS) and often functions through its second messenger, cyclic guanosine monophosphate (cGMP), and protein kinase G (PKG). This study combined NO imaging, immunocytochemistry, biochemistry, and molecular biology to localize NO and its downstream...

Who's Who with Big-Five: Analyzing and Classifying Personality Traits with Smartphones

Gokul Chittaranjan, Jan Blom, Daniel Gatica-Perez

2011 15th Annual International Symposium on Wearable Computers > 29 - 36

2011 15th Annual International Symposium on Wearable Computers (ISWC)

In this paper, we investigate the relationship between behavioral characteristics derived from rich smart phone data and self-reported personality traits. Our data stems from smart phones of a set of 83 individuals collected over a continuous period of 8 months. From the analysis, we show that aggregated features obtained from smart phone usage data can be indicators of the Big-Five personality traits...

New Metaphors from Old Practices—Mobile Learning to Revitalize Education in Developing Regions of the World

Divya Viswanathan, Jan Blom

IEEE Transactions on Learning Technologies > 2010 > 3 > 1 > 18 - 23

By drawing on practices and metaphors familiar to children in the Indian school environment, we aim to develop mobile learning solutions that are grounded on the existing educational practices but have the potential of revitalizing the approach to learning technologies in a developing world context such as India. This paper outlines key findings of our user-centric research to the Indian educational...

Motivations in personalisation behaviour

Antti Oulasvirta, Jan Blom

Interacting with Computers > 2008 > 20 > 1 > 1-16

A number of emerging technologies including mobile phones and services, on-line shopping and portals, and games and communities are designed to provide users with control over appearance and functioning. Understanding why users personalise could help design personalisation features so that they promote the acceptance and adoption of information and communication technology (ICT). This paper examines...

Radiotherapy for oesophagus carcinoma: the impact of p53 on treatment outcome

Jacqueline Pomp, Jacob Davelaar, Jan Blom, Cees van Krimpen, more

Radiotherapy and Oncology > 1998 > 46 > 2 > 179-184

Background and purpose: Wildtype p53 protein plays an important role in the cellular response to ionizing radiation and other DNA damaging agents and is mutated in many human tumours. We evaluated the relationship of the immunohistochemically determined p53 protein status and the disease control with radiotherapy alone for carcinoma of the oesophagus.Materials and methods: Immunostaining for p53 protein...
