The frequency and length of daily phone use continues to rise, especially among young people. It’s a global concern, driving recent decisions to ban phones in schools in Canada, the United States and elsewhere.

But we need to look at the phones themselves to get the bigger picture. As I argue in my newly published book, Needy Media: How Tech Gets Personal, our phones — and more recently, our watches — have become animated beings in our lives. These devices can build bonds with us by recognizing our presence and reacting to our bodies. Packed with a growing range of technical features that target our sensory and psychological soft spots, smartphones create comforting ties that keep us picking them up. The emotional cues designed into these objects and interfaces imply that they need our attention, while in actuality, the devices are soaking up our data.A responsive presenceFace recognition, geolocation, touchscreens, vibration, sound alerts and audio and motion sensing all play their part in catching our attention and responding to our actions. Separately, these may not create a strong emotional attachment, but collectively they situate the phone as a uniquely intimate, sensitive and knowing presence in our lives.Take facial recognition locks, for example. Convenient for quick access, a smartphone will light up and unlock with a glance when it encounters a known and trusted face. When introducing Face ID in 2017, Apple claimed: “Do it up anyway you do it, Face ID learns your face. It learns who you are.” This implies a deeper user-device connection, like the one we have with folks we know when we spot them crossing our path.Some devices have repurposed the hand wave — a typical gesture of friendship — into a feature that triggers the camera to take a photo.Geolocation converts networking signals into a dot on a map, and we see that dot as us — not our phone — just as we may see the dots of our friends’ phones on the map as them.Phantom vibrationsSensory cues play a strong role. Touchscreens allow the phone’s interface to react subtly, like edge lighting and rubberbanding, to mimic the pliability of skin.Vibration and sound alerts make us highly sensitive to the smallest movement or sound from the device. This produces conditions like phantom vibration syndrome, where we imagine that the device requires our attention, even when it doesn’t. Audio and motion sensing, on the other hand, allows the device to react to us almost instantly, as when it lowers its ringing on an incoming call when we grab its body. Phones are constant companions as we move through our days. (Muradi/Unsplash), CC BY Roots and originsMost of these features were developed decades ago for other uses. GPS was created by the U.S. military in the early 1970s, then was adopted by hikers and sailors to both navigate and to allow others to locate them if necessary.Vibration alerts were created for pagers in the late 1970s for professionals — from hospital staff to travelling salespeople — to notify them of an important phone call.Sound alerts became more widespread with Tamagotchi and other 1990s digital pets. Those toys are especially significant when discussing today’s psychological dependency on portable devices. Through their beeping cries for attention, Tamagotchi trained millions of school-age millennials to build emotional attachments to virtual handheld companions needing care and nurturing. Not surprisingly, these toys were banned in many schools for their tendency to disrupt classes and distract students.Indiscriminate trackingPhones have become an essential part of who we are and how we behave. But there’s also an issue of privacy around our most intimate actions and behaviours. Sensors keep sensing, measuring sounds, movements and proximity.There is the risk that our dependency will intensify as phones learn things about us that have, until recently, been off limits.Sleep is a good example. Audio and motion sensing allows the device to get a reasonable picture of when and how we sleep, often collecting and sharing biometric data through pre-loaded health and wellness apps.Another example is more sophisticated facial recognition, that will not only be able to recognize a face, but also analyze expressions to determine alertness or mood. All of this collected data may have profound consequences, making our bodily behaviour, our off-line interactions with others and our emotional fragility a regular part of the data profiles used to leverage our lives for corporate profit.Managing dependencyShort of powering off or walking away, what can we do to manage this dependency? We can access device settings and activate only those features we truly require, adjusting them now and again as our habits and lifestyles change.Turning on geolocation only when we need navigation support, for example, increases privacy and helps break the belief that a phone and a user are an inseparable pair. Limiting sound and haptic alerts can gain us some independence, while opting for a passcode over facial recognition locks reminds us the device is a machine and not a friend. This may also make it harder for others to access the device.So-called “dumb phones” limit what a user can do with their devices, though that’s a tough sell when 24/7 connectivity is becoming an expectation.Manufacturers can do their part by placing more invasive device settings in the “off” position in the factory and being more transparent about their potential uses and data liabilities. That’s not likely to happen, however, without stronger government regulation that puts users and their data first.In the meantime, at a minimum, we should broaden our public discussions of dependency beyond social media, gaming and artificial intelligence to acknowledge how phones, in themselves, can capture our attention and cultivate our loyalty.Stephen Monteiro does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment.
