When Half-Life was first released in 1998 by Valve, it was revolutionary. Before it came out, most first-person shooters took place in static environments with storytelling occurring almost entirely through cut scenes — if at all. Half-Life featured interactive environments that were often used for puzzle-solving and plot elements that unfold during gameplay. 2004’s Half-Life 2 dramatically expanded on those ideas. We haven’t been lucky enough to get a Half-Life 3 yet, but Valve did release the virtual reality-focused Half-Life: Alyx earlier this year. Redditor Ephex_ recently built a glove inspired by Half-Life: Alyx that is absolutely packed full of sensors.
Half-Life: Alyx takes place between the events of Half-Life and Half-Life 2, and features many physics puzzles and environmental interaction. But, unlike the other games in the Half-Life series, it is intended to be played only in virtual reality. Because of that, your character’s hands are an important part of gameplay, as they mirror your own hands in the real world. Your character, Alyx Vance, wears a special glove on her left hand that the player uses to interact with the world. It’s that glove that Ephex_ has replicated in the real world. It isn’t a visually-accurate recreation, and it certainly can’t manipulate gravity. But it does have a lot of interesting functions.
This glove has two displays that can show the data collected by the sensors: an OLED screen and a four digit seven-segment display. Additional output comes from an LED, a buzzer, and a laser pointer. Turning a potentiometer allows the user to switch between functions. Those include a thermometer, humidity sensor, pressure sensor, altimeter, and even an ultrasonic distance sensor. All of those sensors are monitored by an Arduino Uno board. Power is provided by a single 9V battery. All of the hardware components are strapped onto a mechanic’s glove. It looks a bit “hacked together,” but that reflects the aesthetics of the glove seen in Half-Life: Alyx.
