Portrait: Martin Hitz
Martin Hitz
Professor
Martin is heading the group and curr­ently working on his con­tri­bu­tions to the group’s text­book pro­ject on ‘User-Centered Prac­tice Patterns for In­ter­ac­tive Systems’. He is also draft­ing a ‘Cu­rated Collec­tion on Human-Technology Inter­action in Tour­ism’ for JITT and ed­i­ting a Special Issue on ‘Human-Smarthome Inter­action’ for Sensors. His re­search ideas find their way into the work of his col­le­agues, espe­c­i­ally the more junior ones. The last disser­­ta­­tions com­­plet­ed under his super­­vision dealt with na­tu­ral, in­tu­i­­tive and calm inter­­action.
Portrait: David Ahlström
David Ahlström
Associate Professor
further information
David’s main research inte­rests revolve around the design and empirical evalu­ation of novel user inter­faces and inter­action tech­ni­ques for smart­phones and smart­watches, such as map navigation, menu, and image browsing in­ter­faces, and in-air hand ges­tures, vibration-based input, and touch-commands.

Portrait: Gerhard Leitner
Gerhard Leitner
Associate Professor
Gerhard’s research areas are human system inter­action, usa­bility and user ex­peri­ence, with a special focus on smart homes, specific user groups (elderly, private home owners) and specific goals (active and assi­sted living, com­fort enhance­ment, efficient and easy con­fi­gura­tion and control).
Portrait: Martin Stettinger
Martin Stettinger
Senior Scientist
Martin’s research focus is relat­ed to the topics of re­commen­der sys­tems and human dec­i­sion mak­ing, group re­commen­der sys­tems, as well as con­fi­gu­ra­tors for com­plex pro­ducts and ser­vices in­clud­ing AI-based techniques and con­cepts for in­tell­i­gent know­ledge re­pre­sen­ta­tion in in­dust­rial sett­ings.
Portrait: Anton Josef Fercher
Anton Josef Fercher
Predoc Scientist
In his current research, Anton investi­gates new ways to support (end-) users in the do-it-yourself con­fi­guration pro­cess of Smart Homes. Here his special focus lies on the app­li­cation of aug­mented reality based inter­faces to pro­vide users with tech­nical back­ground and guid­ance, as well as possi­bili­ties of risk-less ex­plo­ration on demand.
Portrait: Mahmoud Sadeghi
Mahmoud Sadeghi
Predoc Scientist
Mahmoud explores diff­e­rent poss­i­bi­li­ties and stra­te­gies of using evo­lu­tio­nary algo­rithms to im­ple­ment graph­i­cal user in­ter­faces which auto­ma­ti­cally change them­selves across time acc­ord­ing to the user’s cur­rent acti­vi­ties and needs.
