A brief introduction
to Jukka..

• Topic of the thesis Interaction Methods in
  Haptic Environment
• Advisors Kari-Jouko Räihä, Roope Raisamo
• Background M.Sc. in Computer Science, University
  of Tampere (2003)
• Professional interests HCI, multimodal
  interfaces, haptics
• Affiliated to UCIT since summer 2003 (funding
  2006-2009)
• Born in 1977, lives in a common-law marriage,
  plays with 11 children
• Hobbies include mostly lots of sports and often
  inadequate amount of literature plus countless
  hours of time spent on the playgrounds

What is haptics, anyway?

• Derived from the Greek word haptesthai, meaning
  to touch
• Just a fancy synonym for touch..?
• describe the field of research exploring human
  perception and interactions mediated via the
  sense of touch
• used in context of hardware and software systems
  providing touch feedback
• Haptic feedback means using touch as a medium for
  interaction

Motivation

• Human perceptual system forms a holistic
  experience from the world outside
• vision tends to dominate the other senses
• computer interfaces based merely on visual (and
  auditory) modalities lack the feeling of reality
• Haptic modality can help to create more natural
  and informative interfaces, because it
• is intrinsically bidirectional,
• provides multi-parametered feedback,
• is either active exploration or passive sensing,
  and
• helps to make the interaction more emotional.

Research problems

• The questions risen so far
• How do different properties of touch affect the
  perceived feedback?
• What are the effects caused by different designs
  of the devices?
• Where it is at its best?
• How to combine it with other modalities?
• Is it sensible to design interfaces for all?
• How does the haptic memory work?
• How detailed guidelines it is possible to define?
• Design dimensions for haptic research

Approaches

• Empirical research
• basic research on haptic sensing and interaction
• validate the prototypes
• compare the new interaction techniques and
  artifacts with the existing ones

• Constructive research
• ideas
• prototypes
• testing
• publication

Objectives

• Three phases of research
• I defining thresholds and limits for
• perceiving haptic parameters
• II designing natural interaction techniques
• based on the devices used in the research
• III implementing a prototype environment
• taking advantage of the results
• PhD in 2009

Goals

• To lay foundations for haptic signal language
• To gain new knowledge on the haptic interaction
• To develop interaction techniques that take into
  account the different qualities of the current
  haptic devices

Activities for 2006

• Continue the research on the detectability
  thresholds
• creating a set of tasks for more exact measures
• comparisons between a greater variety haptic
  devices
• 2 publications (journal conference)
