Exploring How Drivers Perceive Spatial Earcons in Automated Vehicles
David Beattie, Lynne Baillie, Martin Halvey
Article No.: 36
Automated vehicles seek to relieve the human driver from primary driving tasks, but this substantially diminishes the connection between driver and vehicle compared to manual operation. At present, automated vehicles lack any form of continual,...
EarBit: Using Wearable Sensors to Detect Eating Episodes in Unconstrained Environments
Abdelkareem Bedri, Gregory Abowd, Richard Li, Malcolm Haynes, Raj Prateek Kosaraju, Ishaan Grover, Temiloluwa Prioleau, Min Yan Beh, Mayank Goel, Thad Starner
Article No.: 37
Chronic and widespread diseases such as obesity, diabetes, and hypercholesterolemia require patients to monitor their food intake, and food journaling is currently the most common method for doing so. However, food journaling is subject to...
How to Remember What to Remember: Exploring Possibilities for Digital Reminder Systems
R. N. Brewer, M. R. Morris, S. E. Lindley
Article No.: 38
Digital reminder systems typically use time and place as triggers to remind people to perform activities. In this paper, we investigate how digital reminder systems could better support the process of remembering in a wider range of situations. We...
Participatory Sensing or Participatory Nonsense?: Mitigating the Effect of Human Error on Data Quality in Citizen Science
Matthias Budde, Andrea Schankin, Julien Hoffmann, Marcel Danz, Till Riedel, Michael Beigl
Article No.: 39
Citizen Science with mobile and wearable technology holds the possibility of unprecedented observation systems. Experts and policy makers are torn between enthusiasm and scepticism regarding the value of the resulting data, as their decision...
The current norm for measuring blood pressure (BP) at home is using an automated BP cuff based on oscillometry. Despite providing a viable and familiar method of tracking BP at home, oscillometric devices can be both cumbersome and inaccurate with...
Device-free human sensing is a key technology to support many applications such as indoor navigation and activity recognition. By exploiting WiFi signals reflected by human body, there have been many WiFi-based device-free human sensing...
Does this App Really Need My Location?: Context-Aware Privacy Management for Smartphones
Saksham Chitkara, Nishad Gothoskar, Suhas Harish, Jason I. Hong, Yuvraj Agarwal
Article No.: 42
The enormous popularity of smartphones, their rich sensing capabilities, and the data they have about their users have lead to millions of apps being developed and used. However, these capabilities have also led to numerous privacy concerns....
Detecting Gaze Towards Eyes in Natural Social Interactions and Its Use in Child Assessment
Eunji Chong, Katha Chanda, Zhefan Ye, Audrey Southerland, Nataniel Ruiz, Rebecca M. Jones, Agata Rozga, James M. Rehg
Article No.: 43
Eye contact is a crucial element of non-verbal communication that signifies interest, attention, and participation in social interactions. As a result, measures of eye contact arise in a variety of applications such as the assessment of the social...
Devices and Data and Agents, Oh My: How Smart Home Abstractions Prime End-User Mental Models
Meghan Clark, Mark W. Newman, Prabal Dutta
Article No.: 44
With the advent of DIY smart homes and the Internet of Things comes the emergence of user interfaces for domestic human-building interaction. However, the design trade-offs between the different representations of a smart home’s capabilities...
Remote Control by Body Movement in Synchrony with Orbiting Widgets: an Evaluation of TraceMatch
Christopher Clarke, Alessio Bellino, Augusto Esteves, Hans Gellersen
Article No.: 45
In this work we consider how users can use body movement for remote control with minimal effort and maximum flexibility. TraceMatch is a novel technique where the interface displays available controls as circular widgets with orbiting targets, and...
Lessons Learned from Two Cohorts of Personal Informatics Self-Experiments
Nediyana Daskalova, Karthik Desingh, Alexandra Papoutsaki, Diane Schulze, Han Sha, Jeff Huang
Article No.: 46
Self-experiments allow people to investigate their own individual outcomes from behavior change, often with the aid of personal tracking devices. The challenge is to design scientifically valid self-experiments that can reach conclusive results....
Building Cognition-Aware Systems: A Mobile Toolkit for Extracting Time-of-Day Fluctuations of Cognitive Performance
Tilman Dingler, Albrecht Schmidt, Tonja Machulla
Article No.: 47
People’s alertness fluctuates across the day: at some times we are highly focused while at others we feel unable to concentrate. So far, extracting fluctuation patterns has been time and cost-intensive. Using an in-the-wild approach with 12...
