barış serim / hci research

I am a doctoral student at UIx Group, University of Helsinki and Department of Design, Aalto University. My research is on using gaze and visual attention information for human-computer interaction. To this end, I prototype user interfaces that combine various sensing technologies such as eye tracking, head tracking and touch input.

Visual Attention-Based Access: Granting Access Based on Users' Joint Attention on Shared Workspaces

During collaboration, individual users' capacity to maintain awareness, avoid duplicate work and prevent conflicts depends on the extent to which they are able to monitor the workspace. We propose managing access by taking the visual attention of collaborators into account. For example, actions that require consensus can be limited to collaborators' joint attention, editing another user's personal document can require her visual supervision and private information can become unavailable when another user is looking. We prototyped visual attention-based access for 3 collaboration scenarios on a large vertical display using head orientation input as a proxy for attention. (UbiComp'18) doi pdf video

Gaze-Adaptive Above and On-Surface Interaction

We explore the combination of above-surface sensing with eye tracking to facilitate concurrent interaction with multiple regions on touch screens. Conventional touch input relies on positional accuracy, thereby requiring tight visual monitoring of one's own motor action. In contrast, above-surface sensing and eye tracking provides information about how user's hands and gaze are distributed across the interface. In these situations, we facilitate interaction by 1) showing the visual feedback of the hand hover near user's gaze point and 2) decrease the requisite of positional accuracy by employing gestural information.

Pointing while Looking Elsewhere: Designing for Varying Degrees of Visual Guidance during Manual Input

We propose using eye tracking to support interface use with decreased reliance on visual guidance. While the design of most graphical user interfaces take visual guidance during manual input for granted, eye tracking allows distinguishing between the cases when the manual input is conducted with or without guidance. We conceptualize the latter cases as input with uncertainty that require separate handling. We describe the design space of input handling by utilizing input resources available to the system, possible actions the system can realize and various feedback techniques for informing the user.

teaching

I lecture on interactive visualization, interaction techniques, user-centered design and prototying techniques at various bachelor and master level HCI courses at the University of Helsinki. These are Interactive Data Visualization, Human-Computer Interaction and Designing Interactive Systems.

community

I am a frequent reviewer for ACM CHI (excellent reviewer for 2017), MobileHCI, DIS and ISS conferences. I was a PC for CHI'18 Late Breaking Work. I used to organize student activities for the local HelsinCHI community.

stuff I find relevant

Scientific publishing and peer review. I feel like the current system of publishing is long due for a change and we will see developments towards new models of peer review and interactivity.

contact

I am based in Helsinki and open to collaborations. Feel free to contact me through serim(DOT)baris(AT)gmail(DOT)com
