[Exp1_PerformanceData.csv]

Measurements of task performance from experiment 1 in [1]. Column descriptors:

* Participant: unique ID per participant
* Block: identifies experiment block (order of execution)
* Task: identifies experiment task (order of execution)
* TaskId: unique ID per task (participants completed same tasks in random orders)
* SphereSize: refer to [1]
* Sphere: identifies target for task (left or right)
* Success: 0 or 1 (for N or Y)
* Time: task time in milliseconds (see [1])
* TargetX, TargetY, TargetZ: coordinates of target object (all distance in mm relative to Leap Motion)
* FingerX, FingerY, FingerZ: coordinates of user's finger at task end
* IntersectX, IntersectY, IntersectZ: coordinates where the ray intersected the target sphere (see [1])


[Exp2_PerformanceData.csv]

Measurements of task performance from experiment 2 in [1]. Column descriptors:

* Participant: unique ID per participant
* Block: identifies experiment block (order of execution)
* Task: identifies experiment task (order of execution)
* TaskId: unique ID per task (participants completed same tasks in random orders)
* Condition: refer to [1]
* Target: identifies target for task (nearest or furthest away)
* Success: 0 or 1 (for N or Y)
* Time: task time in milliseconds (see [1])
* AimingTime: time spent aiming at targets (see [1])
* TargetingTime: time spent disambiguating selection (see [1])


[Exp2_Survey.csv]

Survey responses from the post-experiment survey. Column titles contain the questions. All numerical ratings are on a 1-7 scale, where 1 was negative and 7 was positive. For example, a "how difficult" question had 1=difficult, 7=easy.
