Raw-Hand Form
Hang gliding's sector called "micro hang gliding (mHG)" includes a sub-sector called "hand hang gliding" (HHG) which differs from hand flying (hand out moving-car window).
HHG has the pilot place his or her hands up in parasol position in a traverse-to-wind and generally parallel-with-the-horizon position; that is, place one's hand up high over one's head; perhaps interweaved fingers from each hand (one of the several options for this HHG mode of flight); control the airfoil shape of the hand wing by cupping and strategic placement of the fingers. When the hand wing is ready: face the wind, if any, and begin to lean the body into the direction of the walk, jog, run. With hand wing up high: control the angle of attack (AoA) of the hands wing(s) to best fit flight desires. When both feet are off the ground mHG occurs with the HHG method. Visualize the flight you wish. Keep your eyes on targets; pick up your feet. You can fly, yes you can! This HHG may be done in active HG airfields for various purposes, say mind readying, wind direction determining, warming up legs and arms, and more. Depending on what one thinks about, how one directs eye and mind, etc. bring on benefits from the HHG. One may hang glide daily on sidewalks, roads, floors, inclines, etc. Every day of the year, no matter the weather. Much of mHG and sectors of HHG can be seen as part of WR (wing running); when both feet are off the ground, then some mHG occurs. Advanced HHG may incorporate mind and body practice over very many issues that may play importantly into other HG sectors.
Another form of HHG involves what was seen on the cover of Argosy magazine, January, 1962, which was part of the HG renaissance.

In this second form of HHG, the hands of the pilot are used to hang from the glider, not a harness. The tendons of the arm form the kite tethers of the hanging method. This HHG method permits little control, but allows some control; the method allows dropping away from the wing in the system, if wanted.
=========================
One form of unfortunate HHG involves FTHI (failure to hook in) hanging from TCF (triangle control frame); there has been some awful injuries from such mode.
Another form of unfortunate HHG involves inadvertent holding onto a parachute or soaring parachute (PG):

Post subject: Paraglider killed in PV

A paraglider plunged to his death after a gust of wind lifted his chute 100 feet into the air over a rocky Rancho Palos Verdes beach and he lost his grip, authorities said Monday.
Seoung Man Lee, 44, of Torrance was pronounced dead at the scene of the 6:25 p.m. accident Saturday on the beach below the Trump National Golf Club at 1 Ocean Trails Drive, witnesses and the coroner's officials said.
"It was pretty stressful as far as just witnessing it," said Joyce West, who was walking along the beach with her husband. "We were all standing around, `What can we do? What can we do?"'
West said she and her husband walked past some paragliders packing their parachutes shortly before the accident occurred.
When the couple turned around, they looked up and saw the man hanging from the sail as it lifted into the air.
"He was going up so fast," West said.
Coroner's Department Lt. Cheryl MacWillie said witnesses told investigators that Lee was not wearing the harness or his safety helmet as he was inspecting or preparing to store his paragliding apparatus near the shoreline.
He was grasping both steering handles that were secured by lanyards when a gust of wind inflated the canopy, MacWillie said.
"He was lifted from the beach and quickly gained altitude," she said. "After reaching about 100 feet, he lost hold of his grasp and fell to a rocky patch on the ground."
West said Lee lost his grip with his left hand first and then the other hand came free.
"I guess he panicked," she said. "Instead of letting go, he just rode up with it. It took seconds to get up. It was really, really fast."
Authorities said Lee was married. His wife was not with him at the beach.
