I recently learnt a little known iPad/iPhone trick – that is really useful, especially for people using an iPad in a teaching and learning situation.
If you have a newish headphone set that has a volume control on the headphones – then this can be used to take a photo or video on the iPad. Pressing the volume down button on the headphones – will have the same effect as pressing the button on the screen when in the default camera app.
There are a few uses of using this technique as follows:
- If I am creating a video of myself (e.g. introducing a topic to learners) – I can start and stop the video with my headphones, which are out of site of the camera – without having to lean forward and (visibly) touch the screen.
- If I am carrying out movement analysis in a sports setting, and I have set my iPad up on a tripod (see previous blog post on this topic) – if I touch the screen to start the recording – I risk wobbling the set-up, which reduces the quality of the video. By using the headphones there is no wobble in the system.
- Again if the iPad is on a tripod and I am operating the taking of the photos/videos – by using the headphones, I can do this without having to look at the device – which means I can keep my full attention on the class. If I am pressing the button on the screen, I have to momentarily take my attention away from the class, potentially missing something important.
- If working outdoors in the cold, it is possible to operate the camera with gloves on.
- If working in certain environments such as a workshop, kitchen, farmyard – it is possible to operate the camera even without fully clean hands. At the end of the session you can wipe the controls of the headphones clean.
- If working with disabled learners, the processing of holding the device, and looking at the screen, and pointing in the right direction, and then taking the photo can be tricky for some, often resulting in movement of the device as the on-screen button is pressed. By using the headphones (and possibly a tripod) we can reduce this effect. This won’t work for all – some will find the on-screen button easier to manage, but others will find the headphones option easy to control.
There will be many other uses that I haven’t listed here (maybe people will comment if they can think of any).
