Abstract

We describe the development and testing (across three studies) of an open-source device designed to measure sit-stand desk usage: the Desk Positioning System (DPS). Accuracy of the DPS was assessed under prescribed (Study 1) and free-living (Study 2; video criterion) conditions, across multiple desk-types. Study 3 assessed usability and acceptability in the short-term (1-week) and longer-term (5-weeks).

Results

In Study 1, the DPS was 100% accurate at identifying most conditions (presence at desk 59/72 conditions, detecting desk height 166/168). In Study 2 (n = 10) the DPS demonstrated high accuracy (F1>0.95) and precision (>0.98) against the criterion (7866 observations). Study 3 participants (n = 23) reported high device acceptability in both the short- (mean [sd] 4.4/5 [SD 0.4]) and longer-term (4.6/5 [0.5]). Usability was above the 68-score industry benchmark at the short- (72.4/100 [14.2]) and longer-term (74.7/100 [18.5]).

Conclusion

The DPS may provide an accurate, acceptable and useable way of understanding sit-stand desk usage.

我们介绍了一种用于测量坐立办公桌使用情况的开源设备--办公桌定位系统（DPS）的开发和测试（涉及三项研究）。在规定（研究 1）和自由生活（研究 2；视频标准）条件下，对 DPS 的准确性进行了评估，涉及多种办公桌类型。研究 3 对短期（1 周）和长期（5 周）的可用性和可接受性进行了评估。结果在研究 1 中，DPS 对大多数情况的识别准确率为 100%（在办公桌前 59/72 次，检测办公桌高度 166/168 次）。在研究 2（n = 10）中，DPS 的准确度（F1>0.95）和精确度（>0.98）均高于标准（7866 次观察）。研究 3 的参与者（n = 23）表示，设备在短期（平均值 [sd] 4.4/5 [SD 0.4]）和长期（4.6/5 [0.5]）的可接受性都很高。短期（72.4/100 [14.2]）和长期（74.7/100 [18.5]）可用性均高于 68 分的行业基准。
