The NPA is a detailed mapping of your brain and requires very precise data be collected from the headset. Because the assessment is so targeted, some users will find that they experience difficulty with headset connection, or not getting enough 'good data'. Below are a few tips that may help with completing the NPA successfully:
- Make sure to apply sensor conditioner to each of the headset's 5 sensors before starting the NPA.
- If your eyes are susceptible to dryness, apply eye drops before beginning the NPA.
- Posture can have a big impact on the quality of data the headset can collect. Be sure to sit up straight, and orient your phone so that you are not hunched over, and that your head is not facing down.
- If the headset becomes uncomfortable, remove the headset and take a 15 minute break to get up and walk around.
- Be aware of muscle movement and fatigue. As the CPT nears it's end, you may inadvertently tense up, or feel your eyes start to strain. If this becomes uncomfortable, remove the headset and take a 15 minute break to get up and walk around.
- If you wear contacts: Remove your contacts and use glasses while taking the assessment. If your eyes are susceptible to dryness, apply eye drops before beginning the NPA.
What is causing these errors?
Not enough good data? There can be a number of factors causing this message to be shown. Below are the most common reasons for this.
- Inadvertent muscle tension including: Eye strain, jaw clenching, touching/moving the headset, yawning, leaning over (causing the headset to disconnect), talking, excessive blinking, teeth grinding, eyebrow movement, leg movement, moving the iDevice between hands.
- Bad Headset Connection: If the sensor disconnection window is continually shown, return to the Main Menu, and complete a Warm Up game. This will help to identify if the headset has a stable connection, in which case you will complete the warm up with no errors or sensor disconnects. See the links below for more information.
