analyses_obj_puzzle.xls dataset

The project contains open data, in partial fulfillment of a submission to Scientific Reports (SREP-23-00924A) for the manuscript: Blind people can actively manipulate virtual objects with a novel tactile device authored by Mariacarla Memeo, Giulio Sandini, Elena Cocchi, and Luca BraydaThe dataset contains two sheets.The first sheet 'discreteMeasures' contains the values of independent and dependent variables, for all participants, with one row for each trial of each participantThe second sheet 'averageMeasures', instead, computes variables across all trials of a single participant, for a single resolution of the environment. Therefore all trials of a certain resolution are collapsed in a single row.We label data as follows:ID -> the participant IDgenderresolution[1,2,3] -> categorical variable indicating one of three resolution of the map: 2x2, 2x3 and 3x3group[1,2] -> counterbalanced order of presentation of stimulihorizontal[1/0] -> whether the participant was asked to build a horizontal (1) or vertical (0) parallelepipedtrial match[1,0] -> whether the participant did build what was asked (1) or not (0)execTime[s] -> how long the trial lasted, in secondsnMovements -> how many times the participant pushed any of the four directional buttons of the keyboardidealManhDistance -> what is the minimal amount of movements that the participant can do to build the requested objecttargetManhDistance-> what is the actual amount of movements that the participant performedefficiencyMov(1+nmov/1+idealManh) -> the ratio of the actual amount of movements with respect to the ideal number of movements that led to the correct solution. The number can be lower than one in case the participants is building an object different that what is requestedefficiencyDist(1+targetManh/1+idealManh) -> same as above, but in terms of Manhattans distance. This number does not take into account movements back and fourth the same position, therefore it consider only the starting and ending position of the object.efficiencyDiff(targetMahn-idealMahn/targetMahn+idealMahn) -> a meaasure of consistency between ideal and target Manhattan distance. If it is equal to 1, the match is certainly 0uncertainty(accuracy/execTime) -> a measure of efficacy of being accurate over timemouseUse[s] -> the amount of time the TAMO3 was actively moved on the tabletkeyboardUse[s] -> the amount of time the keyboard buttons where pressedrestTime[s] -> the amount of time no action or motion were detectedtotalTime[s] -> the total trial timeaverageSpeed[mm/s] -> the average speed of the TAMO3 across the trialpercentageMouseUse[%] -> portion of time spent in moving the TAMO3The sheet "averageMeasures" contains average and standard deviations of most of the variables above, computed across all trials of a given resolution of a given subject

本项目包含公开数据集，用于补充提交至《Scientific Reports》（科学报告，SREP-23-00924A）的研究论文，论文标题为《盲人可通过新型触觉设备主动操控虚拟物体》，作者为Mariacarla Memeo、Giulio Sandini、Elena Cocchi与Luca Brayda。
本数据集包含两个工作表。第一个工作表"discreteMeasures"存储所有受试者的自变量与因变量数值，每一行对应一名受试者的一次实验试次。
第二个工作表"averageMeasures"则针对单个受试者、单一场景分辨率，计算其所有实验试次的变量均值，因此某一特定分辨率下的所有实验试次将被合并为一行数据。
本数据集的变量标签说明如下：
1. ID：受试者编号
2. gender：受试者性别
3. resolution[1,2,3]：分类变量，代表三种地图分辨率之一，分别为2×2、2×3与3×3网格
4. group[1,2]：平衡后的刺激呈现顺序
5. horizontal[1/0]：标签变量，指示受试者被要求搭建水平（1）还是垂直（0）平行六面体
6. trial_match[1,0]：标签变量，指示受试者是否按要求完成搭建（1为完成，0为未完成）
7. execTime[s]：实验试次持续时长，单位为秒
8. nMovements：受试者按下键盘上任意四个方向按键的总次数
9. idealManhDistance：搭建目标物体所需的最小移动次数（曼哈顿距离，Manhattan Distance）
10. targetManhDistance：受试者实际完成的移动次数（曼哈顿距离）
11. efficiencyMov(1+nmov/1+idealManh)：实际移动次数与达成正确搭建目标所需的理想移动次数之比。若受试者搭建的物体与要求不符，该比值可小于1
12. efficiencyDist(1+targetManh/1+idealManh)：与efficiencyMov同理，但基于曼哈顿距离计算。该指标不考虑在同一位置来回移动的情况，仅统计物体的起始与终止位置
13. efficiencyDiff((targetManh - idealManh)/(targetManh + idealManh))：理想与目标曼哈顿距离的一致性指标。若该指标等于1，则说明搭建结果与要求完全不匹配
14. uncertainty(accuracy/execTime)：单位时长内的准确率指标，反映随时间变化的任务完成有效性
15. mouseUse[s]：TAMO3设备在平板上被主动移动的总时长，单位为秒
16. keyboardUse[s]：按下键盘按键的总时长，单位为秒
17. restTime[s]：未检测到任何操作或移动的时长，单位为秒
18. totalTime[s]：实验试次总时长，单位为秒
19. averageSpeed[mm/s]：实验试次中TAMO3设备的平均移动速度，单位为毫米/秒
20. percentageMouseUse[%]：移动TAMO3设备的时长占总试次时长的百分比
"averageMeasures"工作表包含上述多数变量的均值与标准差，计算维度为单个受试者在某一特定分辨率下的所有实验试次。
