Conclusions: Elimination of a fiducial marker and application of virtual reality, the International Food Unit™ and an automated training allowed quick food volume estimation and control of the estimation error. The estimated volume could be used to search a nutrient database and determine energy and nutrients in the diet.]]> Wed 22 Mar 2023 14:36:56 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49649 Wed 14 Jun 2023 18:46:51 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:13793 Wed 11 Apr 2018 17:12:08 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55535 Wed 05 Jun 2024 09:38:22 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36082 Wed 05 Feb 2020 13:13:07 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54375 Tue 20 Feb 2024 20:24:25 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39346 Tue 14 May 2024 08:37:30 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33039 Tue 03 Sep 2019 17:55:08 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30430 3), subdivided into eight 2 cm sub-cubes for estimating smaller food volumes. Compared with currently used measures such as cups and spoons, the IFU™ standardizes estimation of food volumes with metric measures. The IFU™ design is based on binary dimensional increments and the cubic shape facilitates portion size education and training, memory and recall, and computer processing which is binary in nature. Methods: The performance of the IFU™ was tested in a randomized between-subject experiment (n = 128 adults, 66 men) that estimated volumes of 17 foods using four methods; the IFU™ cube, a deformable modelling clay cube, a household measuring cup or no aid (weight estimation). Estimation errors were compared between groups using Kruskall-Wallis tests and post-hoc comparisons. Results: Estimation errors differed significantly between groups (H(3) = 28.48, p < .001). The volume estimations were most accurate in the group using the IFU™ cube (Mdn = 18.9%, IQR = 50.2) and least accurate using the measuring cup (Mdn = 87.7%, IQR = 56.1). The modelling clay cube led to a median error of 44.8% (IQR = 41.9). Compared with the measuring cup, the estimation errors using the IFU™ were significantly smaller for 12 food portions and similar for 5 food portions. Weight estimation was associated with a median error of 23.5% (IQR = 79.8). Conclusions: The IFU™ improves volume estimation accuracy compared to other methods. The cubic shape was perceived as favourable, with subdivision and multiplication facilitating volume estimation. Further studies should investigate whether the IFU™ can facilitate portion size training and whether portion size education using the IFU™ is effective and sustainable without the aid. A 3-dimensional IFU™ could serve as a reference object for estimating food volume.]]> Thu 24 Mar 2022 11:35:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48432 Thu 16 Mar 2023 14:17:54 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45422 Thu 10 Nov 2022 11:07:07 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45571 Thu 03 Nov 2022 15:10:03 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12888 Sat 24 Mar 2018 10:35:37 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12454 Sat 24 Mar 2018 08:17:51 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29530 Sat 24 Mar 2018 07:32:29 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28996 Sat 24 Mar 2018 07:29:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39175 Mon 23 May 2022 14:54:30 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37432 Mon 16 Nov 2020 17:04:51 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35700 Fri 25 Oct 2019 13:27:18 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35670 Fri 22 Apr 2022 10:23:52 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41778 Fri 12 Aug 2022 12:03:26 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36859 Fri 10 Jul 2020 19:14:42 AEST ]]>
