Projector Apps for Wireless Devices

Q: I’ve got both an iPhone and an iPad, and occasionally I find useful content for my dance classes that I’d like to share with my students on both devices. Is there a way to project content from all of my devices easily—and preferably wirelessly?

A: A great way to get more functionality out of any projector is a computer app called Reflector. You use this app to project an iPad or iPhone onto your computer, which can in turn hook up to your projector. There’s no extra hardware or plugging and unplugging of devices required. You’re now free to move about the room with your device in your hand as you project its screen image for your class.

Reflector relies on your iPad or iPhone’s (4S or later models) ability to connect through AirPlay. This means that as long as your computer and device are on the same WiFi connection, you can connect them. This also means that if your students are using Apple devices, too, they can project their screens onto your computer as well. Not to worry: You can set a password to limit who has access to presenting information on your computer.

You can even show multiple iPads at the same time, allowing you to compare two or more students’ work right in front of the class. Reflector works on both Mac and PC, and it starts at $12.99.

Another option for wireless projection is Apple TV. It allows you to stream from your computer or AirPlay from your iPhone or iPad, and it also lets you play your iTunes through it. Apple TV is significantly more expensive and does not allow you to project more than one device at a time, but it does support quite a bit of content, like Netflix and Hulu Plus.

I often teach ballet over Zoom in the evenings, shortly after sunset. Without the natural light coming from my living room window, I drag a table lamp next to my portable barre so that the computer's camera can see me clearly enough. I prop the laptop on a chair taken from the kitchen and then spend the next few hours running back and forth between the computer screen of Zoom tiles and my makeshift dance floor.

Much of this setup is the result of my attempts to recreate the most important aspects of an in-person dance studio: I have a barre, a floor and as much space as I can reasonably give myself within a small apartment. I do not, however, have a mirror, and neither do most of my students.

If you'd hear it on the radio, you won't hear it in Anthony Lo Cascio's tap classes.

"If I play a song that my kids know, I'm kind of disappointed in myself," he says. "I either want to be on the cutting edge or playing the classics."

He finds that most of today's trendy tracks lack the depth needed for tap, and that there's a disconnect between kids and popular music. "They have trouble finding the beat compared to older genres," he says.

After the birth of her daughter in 2018, engineer Lisa McCabe had reservations about returning to the workforce full-time. And while she wanted to stay home with the new baby, she wasn't ready to stop contributing financially to her family (after all, she'd had a successful career designing cables for government drones). So, when she got a call that September from an area preschool to lead its dance program, she saw an opportunity.

The invitation to teach wasn't completely out of the blue. McCabe had grown up dancing in Southern California and had a great reputation from serving as her church's dance teacher and team coach the previous three years (stopping only to take a break as a new mother). She agreed to teach ballet and jazz at the preschool on Fridays and from there created an age-appropriate class based on her own training in the Cecchetti and RAD methods. It was a success: In three months, class enrollment went from six to 24 students, and just one year later, McCabe's blossoming Lovely Leaps brand had contracts with eight preschools and three additional teachers.
