Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.

Abstract (eng): The objective of our study was to design, implement, and evaluate an oculomotor training system for beginning readers.
The system is based on the theory of optimal viewing position for word identification.
It consists of an eye tracking device and a computer program that gives real-time feedback in the form of a game to the reader about their fixation position on words.
An experimental study was conducted with 8- year old children.
The effectiveness of the training system was evaluated for each child by comparing saccade landing site distributions, gaze durations, and number of fixations per word before and after playing the game.
We found that the peak of the landing site distribution moved towards the optimal viewing position after playing the game.
We also determined that training had a positive effect on the evaluated measures in the majority of subjects.
We propose that this type of oculomotor training may have potential benefits for some underperforming beginning readers or dyslexic readers.
Abstract (fin): Tutkimuksen tavoite oli suunnitella, toteuttaa ja arvioida aloitteleville lukijoille tarkoitettua silmänliikkeiden kontrollin harjoittelujärjestelmää.
Järjestelmä perustuu teoriaan optimaalisesta katseenkohdistuspaikasta sanan tunnistamiseksi.
Se koostuu silmänliikeseurantalaitteesta ja tietokoneohjelmasta, jotka antavat reaaliaikaista palautetta pelin muodossa lukijalle hänen fiksaatiopaikastaan sanassa.
Kokeellinen tutkimus tehtiin 8-vuotiaiden lasten kanssa.
Järjestelmän vaikuttavuutta arvioitiin jokaisen lapsen kohdalla verraten sakkadien laskeutumispaikkajakaumaa, katseen kestoa ja fiksaatioiden määrää sanaa kohti ennen ja jälkeen pelin pelaamisen.
Päädyimme tulokseen, että koulutuksella oli positiivinen vaikutus arvioinnin kohteena olleiden mittarien valossa suurimmassa osassa koehenkilöitä.
Tämänkaltaisesta silmänliikkeiden kontrollia tukevasta harjoittelujärjestelmästä saattaisi potentiaalisesti olla apua lukihäiriöisille tai aloitteleville heikkotaitoisille lukijoille.
