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.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng):A piezoelectric haptic user interface (UI) demonstrator is a device that shows the capabilities of piezoelectric elements for generating vibration feedback to a user through an interface having button-less keys.
The existing piezoelectric haptic UI demonstrates piezoelectric vibrational feedback to some extent but is limited due to drawbacks, such as low strength of the haptic feedback, the absence of visual feedback in the form of back-lighting, limited number of keys that can be controlled by a single microprocessor, low modularity of the design, difficulty in prototype testing, and high risk of errors in the assembly.

The main purpose of this thesis is to design and develop an improved user interface demonstrator which increases the visibility of numerous types of sensational feedback produced by piezoelectric technology, and show the advantages that are only possible with this technology.
The existing piezoelectric haptic UI demonstrator of Aito Interactive Oy was developed further for this thesis, in addition to a brief review of some different methods for generating haptic feedback in a user interface.
The advantage of this haptic feedback over capacitive and other similar types of feedback is highlighted.
The new prototype is tested to meet customer requirements in terms of functionality, durability, environmental temperature, and moisture effects.

This next generation haptic UI demonstrator fulfills all the important requirements lacking in the current generation.
However, the demonstrator designed in this thesis will further be improved in the coming years to meet the ever-changing market needs of user interfaces and stay ahead of the competition.
