Thematic presentations

1. Challenges in Augmented Reality usability/UX (Beatriz Sousa Santos)
2. Magic and Realism in 3D User Interfaces (Beatriz Sousa Santos)
3. [Sérgio Pereira] Evaluation methods for immersive virtual environments (Beatriz Sousa Santos)
4. [Malik Saad Sultan] Evaluation methods for gesture-based interfaces (Beatriz Sousa Santos)
5. Study of VR Frameworks possible to be used in Augmented/Virtual Reality (Paulo Dias): This work involves a bibliographical research on existing VR Frameworks (for example VRJuggler, Unity, etc.) to evaluate the existing frameworks that allow easy integration of all the available equipment at DETI/IEETA. The work also involves small demonstrations of most interesting frameworks to show how easy is the creation of VR worlds and the integration of VR equipment with the frameworks.
6. [Filipe Alves] Use of Gesture in Virtual Environments (Paulo Dias): With the development of affordable gesture tracking sensors like Kinect or Leap motion, it is now possible to use gestures to interact with virtual environments. This objective is to study how these sensors may be used in Virtual Environments, what are their benefits and limitations and present examples of applications.
7. [Paula Branco] Human-Robot Interaction (José Creissac Campos): Human-Robot Interaction (HRI) is a multidisciplinary area addressing the challenges arising from the increasingly closer interaction between robots and humans. The goal is to produce a review of the state of the art, identifying the current main themes and research challenges in the area.
   • Bray-Miners et al. wrote a report presenting an extensive literature review on HRI for unmanned vehicles operation. Alma et al. review addresses physical HRI, focussing safety and dependability in particular. The goal is to provide an overview of the different types of HRI and the relevant research challenges for the area.
8. [Cláudio Silva] Automated usability evaluation (José Creissac Campos): A number of tools have been proposed over the years with the goal of automating (parts of) a usability evaluation process, from capturing usability relevant data to suggesting improvements to designs. The goal is to identify which techniques and tools can we use to support usability evaluation, discussing also the tradeoffs implied in their use?
   • Ivory and Hearst have written a review on The State of the Art in Automating Usability Evaluation of User Interfaces. The review is a good starting point, but is now 14 years old. Present a summary of the review, but look also for what has been done since then.
9. [Marco Couto; David Aparício] Evaluation techniques for safety and mission critical interactive computing systems (e.g. medical devices) (José Creissac Campos): Traditional usability evaluation techniques are not exhaustive and systematic enough to provide the level of guarantee needed by safety of mission critical systems. The goal is to review the state of the art on proposals to guarantee the quality/usability of user interfaces for such systems.
   • Bolton et al. have written a review on Using Formal Verification to Evaluate Human-Automation Interaction. According to the authors the review is not exhaustive and they have invited others to complement it. Present a summary of the review, but look also for approaches not mentioned in the paper.

Welcome

According to the ACM SIGCHI Curricula, Human-Computer Interaction (HCI) is "a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them". The term ’Computing systems’ is used here in a broad sense to denote from systems consisting of a single user interacting with a single computer to spaces enhanced with ubiquitous technology to support the activities or needs of multiple users. Technological development, in particular in the areas of embedded and mobile systems, means that the interface between humans and computers is harder than ever to define while at the same time we become more and more dependent on technology.

Objectives and Learning Outcomes

This course approaches HCI from an Engineering perspective, drawing on the background of the team. As explained above, the objective is to present students with in-depth treatment of a number of selected topics. Upon successful completion of this curricular unit, students should be able to:

• formulate UI hypothesis and devise validation experiments, discussing and applying different evaluation techniques;
• explain the advantages and limitations of describing interactive computing systems with models, as a way to abstract from the systems’ complexity and to reason about their properties;
• discuss the main 3D interfaces available as well as their main applications and limitations, the guidelines for their development, and present the main challenges in 3D and Natural User Interfaces applications;
• identify which types of context information, context-sensitive procedures, and interaction techniques might be realistically supported given the limitations of the technology and the specificities of a particular interaction scenario;
• discuss the advantages, limitations and challenges of interaction through public displays, the role of the shared nature of public displays in user engagement, and the key interaction techniques with them;
• explain the concepts of Lean UX and Model-based User Interface development and contrast their roles in developing interactive computing systems.

Education/MAPiICS Web Preferences

The following settings are web preferences of the Education.MAPiICS web. These preferences overwrite the site-level preferences in TWiki.TWikiPreferences and Main.TWikiPreferences, and can be overwritten by user preferences (your personal topic, eg: TWikiGuest in the Main web).

Web Preferences Settings

These settings override the defaults for this web only. See full list of defaults with explanation. Many of the settings below are commented out. Remove the # sign to enable a local customization.

• Set SKIN=nat
• Set SKINSTYLE = Kubrik
• Set STYLEBORDER = thin
• Set STYLEBUTTONS = off
• Set STYLESIDEBAR = left
• Set STYLEVARIATION = Bluefield
• Set STYLESEARCHBOX = off
• Set PAGETITLE = Interactive Computing Systems
• Set NATWEBLOGO = Interactive Computing Systems

• List of topics of the Education/MAPiICS web:
  • #Set WEBTOPICLIST = Changes | Index | Search | Go

• Web-specific background color: (Pick a lighter one of the StandardColors).
  • Set WEBBGCOLOR = #FFCC99
  • Note: This setting is automatically configured when you create a web

• Image, URL and alternate tooltip text of web's logo.
  Note: Don't add your own local logos to the TWikiLogos topic; create your own logos topic instead.
  • Set WEBLOGOIMG =
  • Set WEBLOGOURL = WebHome
  • Set WEBLOGOALT = Interactive Computing Systems

• List this web in the SiteMap. If you want the web listed, then set SITEMAPLIST to on, do not set NOSEARCHALL, and add the "what" and "use to..." description for the site map. Use links that include the name of the web, i.e. Education/MAPiICS.Topic links.
  Note: Unlike other variables, the setting of SITEMAPLIST is not inherited from parent webs. It has to be set in every web that is to be listed in the SiteMap
  
  • Set SITEMAPLIST = on
  • Set SITEMAPWHAT = MAPi - Interactive Computing Systems
  • Set SITEMAPUSETO = MAPi Doctoral Programme
  • Note: Above settings are automatically configured when you create a web

• Exclude web from a web="all" search: (Set to on for hidden webs).
  • Set NOSEARCHALL =
  • Note: This setting is automatically configured when you create a web

• Prevent automatic linking of WikiWords and acronyms (if set to on); link WikiWords (if empty); can be overwritten by web preferences:
  • #Set NOAUTOLINK =
  • Note: You can still use the [[...][...]] syntax to link topics if you disabled WikiWord linking. The <noautolink> ... </noautolink> syntax can be used to prevents links within a block of text.

• Default template for new topics for this web:
  • WebTopicEditTemplate? : Default template for new topics in this web. (Site-level is used if topic does not exist)
  • TWiki.WebTopicEditTemplate: Site-level default topic template

• Comma separated list of forms that can be attached to topics in this web. See TWikiForms for more information.
  • Set WEBFORMS =

• Users or groups who are not / are allowed to view / change / rename topics in the Education/MAPiICS web: (See TWikiAccessControl). Remove the # to enable any of these settings. Remember that an empty setting is a valid setting; setting DENYWEBVIEW to nothing means that anyone can view the web.
  • #Set DENYWEBVIEW =
  • #Set ALLOWWEBVIEW =
  • #Set DENYWEBCHANGE =
  • #Set ALLOWWEBCHANGE = TWikiAdminGroup
  • #Set DENYWEBRENAME = Set ALLOWWEBCHANGE = JoseCampos,Main.PauloDias,Main.BeatrizSantos,Main.RuiJose
  • #Set ALLOWWEBRENAME = TWikiAdminGroup

• Users or groups allowed to change or rename this WebPreferences topic: (e.g., TWikiAdminGroup)
  • #Set ALLOWTOPICCHANGE = TWikiAdminGroup
  • Set ALLOWTOPICRENAME = TWikiAdminGroup

• Web preferences that are not allowed to be overridden by user or topic preferences:
  • Set FINALPREFERENCES = NOSEARCHALL, ATTACHFILESIZELIMIT, WIKIWEBMASTER, WEBCOPYRIGHT, WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE, DENYWEBRENAME, ALLOWWEBRENAME

Help on Preferences

• A preference setting is defined by:
  3 or 6 spaces * Set NAME = value
  Example:
  • Set WEBBGCOLOR = #FFFFC0
• A preferences setting can be disabled with a # sign. Remove the # sign to enable a local customisation. Example:
  
  • #Set DENYWEBCHANGE = UnknownUser
• Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
  • When you write variable %WEBBGCOLOR% , it gets expanded to #FFCC99
• The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
• You can introduce your own preferences variables and use them in your topics and templates.
