CALL FOR PAPER HASCA WORKSHOP
In Conjunction with UBICOMP 2026
Shanghai, China
****************************************************

We are pleased to announce the International Workshop on Human Activity Sensing Corpus and Applications 2026.

https://hasca2026.hasc.jp/cfp/index.html

This workshop deals with the challenges of designing reproducible experimental setups, running large-scale dataset collection campaigns, designing activity and context recognition methods that are robust and adaptive, and evaluating systems in the real world. We wish to reflect on future methods, such as lifelong learning approaches that allow open-ended activity recognition.

The objective of this workshop is to share the experiences among current researchers around the challenges of real-world activity recognition, the role of datasets and tools, and breakthrough approaches towards open-ended contextual intelligence.

Topics of interest include but are not limited to:
- Data collection / Corpus construction
- Effectiveness of Data / Data Centric Research
- Tools and Algorithms for Activity Recognition
- Real World Application and Experiences
- Sensing Devices and Systems
- Mobile experience sampling, experience sampling strategies:
- Unsupervised pattern discovery
- Dataset acquisition and annotation through crowd-sourcing, web-mining
- Transfer learning, semi-supervised learning, lifelong learning

Please see our website for more details: http://hasca2026.hasc.jp
