HCI on Mobile Devices

 

Objectives

The objective of this project is the study of methods and tools for the development of new forms of interactions for pen based systems (sketching), with applications to text entry on mobile devices.
In particular, we have proposed a new text entry approach based on soft keyboards and a study on its expected performances. The basic idea of the approach is to enhance the keyboard with a menu whose items (characters) can be selected more than once through a single pointer (pen, finger, etc.) stroke, in order to enter particularly frequent text patterns. The gesture to enter these patterns is similar to that used for Cirrin. Furthermore, using well-established methods for measuring the time required for performing simple interactions with pointers on touchscreens, we have evaluated the expected performances of our method. The results, obtained through a text entry simulation, are encouraging with respect to those measured for previous approaches based on menu-augmented keyboard.
 

Activities

In February - March 2010 we lead an experiment in order to test the speed and accuracy of users when using our new text-entry method. The experiment involved a software keyboard implemented on a Sympodium tablet. Results will be soon presented at a CHI Workshop next April. The experiment involved 6 students from our University (and not only from Computer Science) which we want to thank for their patience and also for their enthusiasm:
 
Giovanni Mastroianni
Angelica Chiaviello
Marco Ruggiero
Antonio Liguori
Domenico Depalo
Nicola Gravino 
 
Well,  they will also receive an ipod, thanks to our sponsor Unlimited Software.

FARB Projects

Weblab people participates or has participated to the following FARB Projects:

 


 

FARB Project 2009

Project Title: DEFINIZIONE ED ANALISI DI NUOVE FORME DI INTERAZIONE HUMAN-COMPUTER E MACHINE-BASED 

Principal Investigator: Prof. G. Costagliola

The project is aimed at proceeding with the past researches of the last two years:

 

  1. HCI on mobile devices;
  2. HCI on Web 2.0
In the former ambit, the objective is the study of methods and tools for the development of new forms of interactions for pen based systems (sketching), with applications to text entry on mobile devices. In the latter ambit, the study is aimed at the definition and the development of new architectures for the access to the main services related to Web 2.0 and of new visual techniques and methodologies for the analysis of the interactive user behaviour.  

 

 

Departmental FARB Project 2009 

Project Title: Modelli Matematici e Informatici per il Trattamento dell'Informazione e Studio di problemi fisico-matematici 

Principal Investigator: Prof. V. Loia

 

 

FARB Project 2008

Project Title: Sketch Understanding ed E-learning 

Principal Investigator: Prof. G. Costagliola

 

In the ambit of HCI, the objective is the study of methods and tools for the development of new forms of interactions for pen based systems (sketching), with applications to text entry on mobile devices. In the ambit of e-learning, the study is aimed at the proposal of new techniques and methodologies for the development and the access to learning contents on the  Web (courseware), also investigating the use of pen-based interfaces.
