USC Viterbi Scholar Creates Digital Actuality Button System – USC Viterbi

5 min read

Cami Gomez’s problem combines VR graphics with 3D printed fashions to simulate the feeling of pressing a button.

Sophomore Cami Gomez, like lots of of various school college students, had an unconventional first yr at USC. Her freshman yr was totally digital. However that didn’t stop her from discovering the hands-on engineering different of her wishes.

“My freshman yr was fully on-line, and I used to be anxious I wouldn’t get to pursue any analysis alternatives,” Gomez said. “However I ended up discovering an opportunity to develop my electrical and pc engineering expertise by Professor Heather Culbertson’s HaRVI Lab.”

Via the HaRVI Lab, transient for Haptics, Robotics, and Digital Interplay Lab, Gomez labored on rising digital button pressing. The problem blended VR graphics with 3D printed fashions to simulate the feeling of pressing a button.

Gomez, {{an electrical}} and laptop computer engineering foremost, spent 10 weeks engaged on the problem remotely with help from a graduate scholar mentor, Sandeep Kollanur, a laptop science Ph.D. scholar.

“Each Sandeep and Professor Culbertson have been, and proceed to be, superb mentors to me,” said Gomez. “They’ve helped me by each step of the best way with this mission.”


Creating a ideas for engineering

Gomez’s curiosity in laptop computer engineering began far sooner than her work on the HaRVI problem. She traces this curiosity once more to highschool.

“My highschool calculus instructor was the primary one that pushed me to attempt engineering,” said Gomez. “She even gave me the variety of an engineering alumnus to achieve out to. I used to be unsure at first, however I reached out to them. I grew to become actually curious about their work on the Fb Digital Actuality Labs, so I interned there throughout my junior yr of highschool.”

Via this internship, Gomez met a variety of mentors who helped cultivate her passion for engineering. As she continued to watch this curiosity, Gomez realized how her totally different pursuits factored into engineering.

“I really feel like I’ve a broad number of pursuits. For example, I like visible arts and music, two issues which can be typically thought of very totally different from engineering,” Gomez elaborated. “However, I’ve discovered that engineering requires a artistic thoughts. Engineering is about constructing options to issues, and my expertise with artistic fields has helped me with problem-solving.”

“Engineering is about constructing options to issues, and my expertise with artistic fields has helped me with problem-solving.” Cami Gomez.

Studying one factor new

As she gained additional experience with engineering, Gomez adopted this curiosity into school. She joined USC as a freshman in electrical and laptop computer engineering foremost in 2020. Gomez began her work on the digital button-pushing problem the summer season season after, through USC’s Robotics and Autonomous Techniques (REU) program.

Gomez expressed curiosity in engaged on this problem due to the hands-on nature of its testing and features. Haptics, the science of transmitting and understanding knowledge through contact, is the inspiration of this problem. Digital button-pushing entails tactile objects as rather a lot as a result of it entails VR.

“I hadn’t labored with haptics earlier than, so this appeared like a fantastic alternative to study one thing new,” said Gomez. “And, as soon as I started studying extra about haptics, I noticed how I used to be in it.”

Simulating a button clicking

The problem itself is 2 interactive devices worn on prospects’ fingers. The individual’s left hand presses the digital button, and the button “click on” is simulated on the individual’s correct hand. The left-hand gadget often known as a Leap Movement controller.

Most VR devices, such as a result of the Oculus Quest 2 and the Sony Ps VR headset, are generally worn on one’s face. Nonetheless, Gomez describes the Leap Movement controller as “a pair of VR goggles on your palms.”

On their correct hand, the individual wears a instrument containing an actuator and an amplifier. When the Leap Movement controller detects a digital button press, the actuator strikes on the right-hand gadget. This simulates a button clicking.

Cami Gomez’s work focuses on VR and haptics devices and strategies.

Through the interval of the REU program, Gomez primarily used objects on the market around her residence to create the system. Nonetheless, with the help of Kollanur and Professor Culbertson, she started rebuilding the problem in-person in the midst of the Fall 2021 semester.

“The tip of the mission was additionally form of the start of the mission,” said Gomez. “My aim for the summer season was to have the gadget detect a button press and simulate a click on. I used to be in a position to accomplish that aim. Now, the plan is to enhance this technique.”

She’s moreover been considering the precise approach to broaden this problem previous button-pushing. Transferring sliders, turning rotary knobs, and clicking totally different sorts of buttons all have distinctive sensations. By 3D printing fashions of these objects and interacting with them, the workforce is determining the precise approach to nearly replicate these sensations.

Expertise the world tactically

At present, VR is primarily used inside the on-line recreation commerce, since headsets give gamers a way more immersive gaming experience than TVs or laptop computer screens. Nonetheless, Gomez envisions VR having features inside the medical self-discipline, too.

“VR can enable folks to work together with objects they usually wouldn’t be capable of see or contact in individual,” Gomez says. “As VR applied sciences advance, digital environments with 3d printed, interactive objects inside them grow to be more and more lifelike. This may be leveraged to present hospitalized sufferers an opportunity to expertise the world tactically. That’s what I hope this mission will lay the inspiration for.”
