Quadratic Encoding for Hand Pose Reconstructionfrom Multi-Touch Input
Monday, February 23rd, 2015 from 12-1 pm in GHC 6501.
One of the most compelling challenges in virtual reality today is to allow users to carry out virtual manipulation tasks using their hands. Multi-touch devices are an interesting interface for this task, as they are widely avail-able, they provide users with some haptic sensation of their motions, and they give very precise locations of the fingertips. We introduce a quadratic encoding technique to provide plausible and smooth hand reconstructions from multi-touch input at real-time rates suitable for virtual reality applications. Another nice feature of our data-driven approach is that it does not require explicit identification or registration of fingers. We show that quadratic encoding outperforms linear encoding, cubic encoding, and a PCA based inverse kinematics approach, and is well suited for performing real-time virtual manipulation using a multi-touch device.
The Student Seminar Series is an informal research seminar by and for SCS graduate students from noon to 1 pm on Mondays and Fridays. Lunch is provided by the Computer Science Department (personal thanks to Sharon Burks and Debbie Cavlovich!). At each meeting, a different student speaker will give an informal, 40-minute talk about his/her research, followed by questions/suggestions/brainstorming. We try to attract people with a diverse set of interests, and encourage speakers to present at a very general, accessible level.
So why are we doing this and why take part? In the best case scenario, this will lead to some interesting cross-disciplinary work among people in different fields and people may get some new ideas about their research. In the worst case scenario, a few people will practice their public speaking and the rest get together for a free lunch.
Note: Step #1 below are applicable to all SSS speakers. You can schedule AT MOST THREE talks per semester.
SSS is an ideal forum for SCS students to give presentations that count toward fulfilling their speaking requirements. The specifics, though, vary with each department. For instance, students in CSD will need to be familiar with the notes in Section 8 of the Ph.D. document and follow the instructions outlined on the Speakers Club homepage. Roughly speaking, these are the steps:
