Presentation @ CHI2015: Understanding mobile search & app interactions

Last week JP Carrascal presented our study on the interactions between mobile search and mobile apps at CHI 2015 in Seoul, Korea. JP did a fantastic job presenting and handled the flurry of questions afterwards very well! In fact JP gave two talks in the same “Understanding Everyday Use of Mobile Phones” session chaired by Matt Jones!

The idea behind this work is to understand more about the behaviors and motivations around smartphone users transitioning between mobile search engines and mobile apps (and vice versa) when trying to find information to satisfy their daily information needs. We were also interested in exploring the various triggers and actions associated with mobile search. To shed some light on these mobile search and app interactions we designed and conducted a 2-week, mixed-method study involving 18 Android users in the Bay Area. The deck explains the core motivations, approach alongside key results. Questions or comments feel free to contact JP or I. And if interested in reading the full CHI 2015 paper it’s available here.

CHI 2015 Work-in-progress (WIP) Accepted – Location Requirements in Local Search

We have just had a CHI WIP accepted for presented in Seoul, Korea in April 2015! WooHoo :-) This work-in-progress paper was conducted with Henriette Cramer in which we conducted a large-scale survey via Mechanical Turk to shed light on what factors of location are important when choosing a target place of interest in a local search scenario, namely restaurant search.

The survey was deployed in December 2013 and collected a range of demographic information as well as details regarding participants’ current and most recent locations. The core of the survey was a local restaurant search scenario in which participants were asked to provide freeform textual responses to the following question: Read More

CHI 2015 Paper Accepted! An In-Situ Study on Mobile App & Mobile Search Interactions

We recently discovered that all our hard word has paid off! This past summer, JP Carrascal (a PhD candidate from UPF, Barcelona) and I worked together on a study to understand more about if and how mobile search and mobile app usage interacts. And a full CHI paper reporting our findings has been accepted for publication at CHI 2015 in Korea!

The motivation behind this work is that smartphone users spend much of their time transitioning between mobile search engines and mobile apps (and vice versa) when trying to find information. The figure below helps highlight this fact. The figure shows the timeline of mobile device interactions for a 1 hour period of a single day for an actual participant in our study, showing sequences of mobile device interactions in the form of mobile app launches, home screen interactions and mobile searches.

Mobile Search: A Force to be Reckoned With – ECIR 2013 Industry Talk

On Wednesday 27th of March 2013 I gave an invited industry talk on the topic of mobile search at ECIR 2013 in Moscow. This years edition of ECIR was great.
