Smartphone-Based Learning Analytics
Advantages:
• Unobtrusive
• Suitable for different interaction paradigms
• Constant connectivity
• Enriching logging data
• More personalization
Challenges:
• Smartphone Limitations: Processing Power,
Storage, Battery Life
• Uncontrolled Context: mobility, illumination &
exposure variation, unstable camera
• Privacy Concerns:
-> Cloud Computing, sensor-
fusion for algorithm efficiency
-> sensor-fusion
-> keeping least info: e.g.
cropping of images
