David Filipe Ribeiro da Costa

My name is David Costa, I have a MSc degree on Adaptation of Multimodal Outputs and currently I'm doing my PhD on On-body interaction for visually impaired people. I am a junior member of the Human Computer Interaction and Multimedia research Group (HCIM) since August 2010.


My MSc Thesis was made in scope of GUIDE
My interests in research currently are:

  • On-Body Interfaces
  • Skin Interaction
  • Acessibility
  • Human Computer Interaction
  • Multimodal interaction
  • Adaptive Multimodal Interfaces
  • Usability


I was involved in the following projects:

Student Volunteer

I've been student volunteer in the following conferences:

  • Mobile HCI 2010

Other minor past works

  • A flash application that describes the existent courses on the Informatics Department. This application integrates some accessibility features such as TTS description of the information presented on the screen. All the navigation could be done using the keyboard and the instructions were given by the TTS system. This work was done for the Hypermedia Systems subject.
  • A web application that uses web services to gather georeferencied news and posts about portuguese public figures. This web application uses Tweeter, FriendFeed, Verbatim, Google Blog Search, Youtube, Picasa, Google Geocode and Yahoo Geocode as sources. this work was made for the Web Applications subject.
  • A gesture recognizer that compares the gesture made by the user with a set of gesture templates, then it returns the template which had most score. This gesture recognizer was tested in two contexts: execution of applications associated with gestures; and a Paint-like application that matches the gesture with a function (e.g. draw a circle, undo, etc). This work was done for the Advanced Interaction Techniques subject.
