Understanding mobile search & app interactions

(Slideshare deck courtesy of Karen Church)

Last Wednesday April 22th, I presented the paper “An in-situ study of mobile search and app interactions”, during a session chaired by Matt Jones and titled “Understanding Everyday Use of Mobile Phones”. This took place in Seoul, South Korea, during the International Conference on Human Factors in Camputing Systems, CHI2015. I want to share the deck that Karen Church and I put together for the presentation.

I also want to share some of the implications of our work.

CHI2015 highlights (updated)


This is some sort of log or diary of all the activities I attended during the Conference of Human Factors in Computing Systems–CHI2015 in Seoul, Korea. I also had the pleasure to present two papers, “An In-Situ Study of Mobile App & Mobile Search Interactions” (part of my PhD dissertation) and “To Call or to Recall? That’s the Research Question” (the result of my internship at Yahoo! in Summer 2014).

It was an incredible conference and it was a great opportunity to see old and new friends and colleagues.

I had the pleasure to be invited to the event “Diseño Con-Ciencia”, one of several academic events that took place during the “Cátedra Europa” in the Universidad del Norte. The main focus of the event was research and design. My talked focused why and how Human-Computer Interaction research can serve to inform the process of designing mobile phone technologies. I presented some of my research work as well as some past projects developed by my colleagues at the Human Media Lab, where I al working now.

I also had the opportunity to meet several interesting people, both professors from the university and invited speakers, and to know the campus.

Universidad del Norte is one of the top-ranked universities in Colombia.

Talk at the Universidad ICESI, Cali, CO

I presented some of my research work at the Universidad ICESI, in Cali, Colombia, last Friday, September 12th. The talk spawned very interesting discussions with professors and students from different areas of the university surrounding topics on privacy, economics and HCI. I’d like to thank my hosts Pablo Monroy and Adela Parra. Pablo showed me how the ICESI university has grown and expanded both in physical size and professional scope. Additionally, I had the pleasure to talk with Juan Salamanca, director of the Leonardo research group, and we shared interesting thoughts on HCI and projects involving interaction and design.

MixPerceptions: the hidden sound and movement in paintings

MixPerceptions is an art installation where users interact with artworks using their smartphone or tablets and headphones. The interaction is achieved by means of an augmented reality app that reveals rich and dynamic visual and auditory elements that create an engaging multi-sensorial experience.

MixPerceptions brings paintings to life, offering a unique and personal experience to every user, and provoking emotive feelings while encouraging exploration and engagement.

It was created by a multidisciplinary team consisting of Aurelio San Pedro, José San Pedro, Matylda Smukier and myself.

MixPerceptions was first presented during the Art Exhibition of the ACM Multimedia Conference that took place during October 21-25t of 2013, in Barcelona.

I created the soundtrack, sound design and programmed the audio interaction using Puredata.

Visit MixPerceptions website for more information on the project.
