Bit Tech noticed Valve founder Gabe Newell hinted at a biofeedback peripheral while speaking to Penny Arcade in an interview. Newell said the company has been conducting experiments in the field of biofeedback and biometrics, and hinted that the company may use an incremental approach to get in the peripheral market, similar to how the company created the Team Fortress series.
Speaking in an interview with Penny Arcade, Newell stated clearly that a move into hardware would not be impossible for his previously software-only company. 'Well, if we have to sell hardware we will. We have no reason to believe we’re any good at it,' Newell admitted, 'it's more we think that we need to continue to have innovation and if the only way to get these kind of projects started is by us going and developing and selling the hardware directly then that's what we’ll do.'
Although Newell offered no hints as to what form the hardware might take, he did prove to be enthused about the concept of wearable computing. Discussing experiments that Valve has been carrying out in the field of biofeedback and biometrics, Newell's comments suggested that a PC peripheral could be on the cards.
