Summary:
The wearable EOG goggles were designed to fulfil thefollowing requirements:
1. To achieve a convenient and unobtrusive implementation and minimise user distraction the device needs to be wearable and lightweight.
2. To allow for autonomous long-term use in daily life the device needs to be low-power.
3. The device needs to provide adaptive real-time signal processing capabilities to allow for context-aware interaction.
4. To compensate for EOG signal artefacts caused by physical activity and changes in ambient light an accelerometer and a light sensor need to be added.
Two components in the EOG - goggles and processing unit. Gesture based interaction include blink detection and removal, saccade detection and eye gesture recognition
Discussion:
Looks like a device specification and a user study to support the specification.
Comment: Josh
I think the user study was pretty weak though - didn't ever tell us how many people in the study, nor indicate how long each user wore the devices. More heavy on the device spec, which surprises me for acceptance at CHI.
ReplyDeleteI agree, this looks like a device specification. However, a micro-controller for EOG signal processing based on DSP, it's an impressive device.
