Abstract: 
Searching for information with mobile devices is pervasive. However, mobile devices are limited in numerous ways, leading to less than optimal interaction when dealing with large amounts of information. For example, their small screens and limited input modalities (i.e., touch primarily), results in users performing many minute operations, such as flicking through screens, and opening and closing items of interest. For this reason, for many serious information exploration and decision making tasks, users abandon mobiles in favor of traditional keyboard and mouse cursor input, on laptops or desktops. In my talk, I will present my vision on optimizing the information interaction bandwidth on mobile devices. More specifically, I will present two approaches I have developed to overcome the aforementioned limitations. My first approach includes extending devices' input capabilities by using the around-device in-air space for input. I will give an overview of the various design strategies and outcomes that have led to improved user performances for information exploration tasks. My second approach is an initiative involves augmenting current mobile devices with additional input/output capabilities. I will discuss how multiple mobile devices can enhance users' around-device content browsing experiences. I will also present how these two approaches are effective in comparison to standard mobile touch interactions. At the end of my talk, I will provide an overview of my future research goals which build on these promising results and that aim to improve how users' interact with mobile and wearable devices, specifically when it concerns interacting with large information spaces.

Mohammad Khalad Hasan is a PhD Candidate at the University of Manitoba under the supervision of Dr. Pourang Irani. Khalad earned his M.Sc. degree in Computer Science from the same university. He is currently working as a Research Associate in the Human-Computer Interaction (HCI) Lab at the University of Manitoba where his research focus is on developing and studying novel interactions with mobile and wearable devices. More specifically, he is interested in exploring users’ needs and making an impact in their lives when it concerns efficient mobile interactivity. During his graduate studies, he developed strong collaboration ties with academics as well as with industry partners including Autodesk Research, Canada and Honda Research, Japan. His research work has led to a number of publications, with many appearing in top-tier HCI venues which include the ACM Conference on Human Factors and Systems (ACM CHI) and the ACM Conference on User Interfaces and Technology (ACM UIST). His work has also been recognized through best paper award at ACM Symposium on Spatial User Interaction (ACM SUI) and featured in popular press via the Discovery News and New Scientist outlets. His current focus is on designing and developing novel interfaces for mobile and wearable devices to enable users’ access to digital content anytime, anywhere.
