Streaming what you see as you perform your daily activities. Lifecasting is widely used for sports events of all variety. Over the years, numerous cameras, computers and wireless systems were stitched together to create wearable cameras. Today, cameras are so small, anyone can lifecast, and there are thousands of lifecasters worldwide. Also called "livecasting," "lifelogging," "lifeblogging," "glogging" (cyborg logging), "personal casting" and "mobile blogging" (see moblogging). See live streaming.

The First Lifecaster
In the late 1970s, Steve Mann was the first person to transmit his daily view of the world in real time to the Internet. Later, as a professor in the Department of Electrical and Computer Engineering at the University of Toronto, Mann was instrumental in creating the predominant site for "glogger streaming" and developing wearable cameras (for more information, visit See sousveillance and Webcam.

Steve Mann
In 1980 (left), with an Apple II backpack and helmet video camera, Mann used his own radio protocol to access the Internet wherever he could install his wireless base station. Some 20 years later (right), he wore an eyeglass camera connected to a computer embedded in the fabric of his undershirt, both of which he invented. He is operating a remote control with his left hand. (Images courtesy of Steve Mann.)

A Whole Lot Smaller
Point-of-view (POV) cameras have come a long way from the Apple II on Steve Mann's back. This small GoPro camcorder takes HD videos and can be attached to the body via several mounting accessories. (Image courtesy of Woodman Labs, Inc.,

Smaller Yet
In 2013, Memoto introduced a tiny shirt camera (orange square) that stores up to 4,000 pictures over a two-day period on a single battery charge. (Image courtesy of Memoto AB.)

The Positional Activity Logger Version 1 (a), is a lightweight, battery-operated, automated position sensor, which measures the frequency and duration of uptime versus downtime (sitting or lying) (Eldridge et al 2003b).
Measures of mobility were collected on the day of attachment of the activity logger. Participants wore the activity logger for three consecutive days, including a weekend day (or public holiday).
They were excluded if they: were medically unstable; were non-ambulant; had a history of skin allergy to tape or adhesive surgical dressings; had an unhealed leg wound, local skin condition, or pressure area over the attachment sites of the activity logger; had sensory loss over the attachment sites of the activity logger; or were undergoing radiotherapy.
Physical activity was measured as uptime using the Positional Activity Logger Version 1.
The activity logger reset itself during data collection from two participants, resulting in data being lost.

A recent innovation in the quantification of upright mobilisation has been the development of the Positional Activity Logger (a).
Within 24 hours of surgery, and prior to commencement of upright mobilisation, an activity logger was attached to the thigh where it recorded data continuously for the first four postoperative days before being removed on the morning of Day 5.
Measurement of upright mobilisation: Uptime was measured using the Positional Activity Logger. The battery-operated activity logger (90 x 54 x 18 mm) was adhered to the lateral aspect of the right thigh and recorded uptime when the thigh was in a position greater than 45 degrees to the horizontal axis (ie, during standing and walking).
On each day the activity logger was worn, participants were asked to describe their pain relief during mobilisation as adequate or inadequate.
It's really getting people out exploring their neighbourhoods, and at the same time, clocking up the steps on their Fitbits (other fitness activity loggers are available) and enjoying the fresh air.
