Manual material handling tasks, including vehicle and building maintenance, animal care, and seed preparation, will be video-recorded using a digital video camcorder (Sony Handycam HD). Exposure to manual handling will be summarized by reviewing the data with Observer XT event-logging software (Noldus Information Technology Inc, Leesburg, USA) into daily counts and durations, and then compared with risk assessment guidelines such as the National Institute for Occupational Safety and Health (NIOSH) lifting equation, American Conference of Industrial Hygienists (ACGIH) Lifting threshold limit value (TLV), University of Michigan’s Three-Dimensional Static Strength Prediction Program (3DSSPP) and psychophysical acceptability tables [45 (link),46 ].

We used a rectangular experimental tank of size 120 × 120 cm, made of glass, supported by a structure of metal beam 20 cm high. A plywood plate was interposed between the mesh and the basin to dampen the forces exerted on the glass basin by its own weight and water. This structure also enables the attenuation of vibrations. The setup was placed in a chamber made by four opaque white curtains surrounded by four LED light panels to provide an isotropic lighting. A circular tank of radius R = 250 mm was set inside the experimental tank filled with 7 cm of water of controlled quality (50% of water purified by reverse osmosis and 50% of water treated by activated carbon) heated at 24.9°C (±0.8°C). Reflection of light due to the bottom of the experimental tank is avoided thanks to a white PVC layer.
Each trial started by placing groups of N = 5 fish randomly sampled from the breeding tank into the circular tank. Fish were let for 10 minutes to habituate before the start of the trial. A trial then consisted of one hour of fish freely swimming in the circular tank with experimenters out of the room. Fish trajectories were recorded by a Sony HandyCam HD camera filming from above the setup at 25 Hz (25 frames per second) in HDTV resolution (1920 × 1080p). We performed 11 trials with groups of N = 5 fish, and for each trial, we used different fish taken from the breeding tank.

Materials associated with each of the interactive activities are summarized in Table 1. Materials included printed and laminated cards as well as apps presented on two iPad Air devices with 9.7-inch touch screens, one Samsung Galaxy Tab 2 tablet computer with 10.1-inch touch screen, and one Asus EeeTop PC with 15-inch touch screen. The latter was used to demonstrate the Novel Assessment of Nutrition and Ageing (NANA) method, a research tool, which is pictured in Figure 1. In addition, at the beginning of their first session, participants completed a demographics questionnaire, requesting information on age, education, experience using different types of everyday technology, and self-perceived health status. Sessions were videotaped using a Sony HD Handycam on a tripod and were audiotaped using three Olympus digital audio recorders.
